European data stored in the "cloud" could be acquired and inspected by U.S. law enforcement and intelligence agencies, despite Europe's strong data protection laws, university researchers have suggested.
A research paper written by legal experts at the University of Amsterdam's Institute for Information Law and titled "Cloud Computing in Higher Education and Research Institutions and the USA Patriot Act" supports previous reports that the antiterror Patriot Act could theoretically be used by U.S. law enforcement to bypass strict European privacy laws to acquire citizen data within the European Union.
The Patriot Act, signed into law in 2001, granted some new powers to U.S. authorities, but it was mainly a "framework law" that amended and strengthened a variety of older laws, such as the Foreign Intelligence Services Act and the Electronic Communications Privacy Act (ECPA).
"Most cloud providers, and certainly the market leaders, fall within the U.S. jurisdiction either because they are U.S. companies or conduct systematic business in the U.S.," Axel Arnbak, one of the authors of the research paper, told CBS News.
"In particular, the Foreign Intelligence Surveillance Amendments (FISA) Act makes it easy for U.S. authorities to circumvent local government institutions and mandate direct and easy access to cloud data belonging to non-Americans living outside the U.S., with little or no transparency obligations for such practices -- not even the number of actual requests."
This holds true for requests targeted at non-U.S. individuals and for entire business records, he added.
Obama signs extension of Patriot Act
Sophie in 't Veld, Dutch vice chair of the European Parliament's civil liberties committee, welcomed the research, adding that it "provided further evidence" to support the theory.
She told CBS News, however, that the European Commission's proposals for new data protection rules will not solve the potential conflicts posed by third country law and that the lengthy period of time it takes for EU laws to become ratified, "would not be a reason to let the situation be for several years to come."
Information security, privacy, and data protection lawyer Bryan Cunningham, who worked under both Democratic and Republican administrations, most recently as deputy legal advisor to former U.S. National Security Advisor Condoleezza Rice under President George W. Bush, told CBS News that this "important report" should "help correct a widespread post-9/11 misconception" that the Patriot Act and related legislation "provided vast new powers for the U.S. government to gain access to sensitive communications and data of non-U.S. persons."
The research resurfaces questions about the security and sovereignty of citizen and government data in an ever-connected global and borderless online world. It also supports a ZDNet report that European data protection rules do not protect EU citizens' data against extra-territorial third country law, such as that of the United States.
Months after the research was published, Microsoft U.K. Managing Director Gordon Frazer was the first to publicly admit that the software giant could not guarantee that European citizen data stored in EU-based data centers would not leave the European Union under any circumstances, including under a Patriot Act request.
"Neither can any other company," Frazer noted.
Frazer's disclosure triggered outrage among politicians in the European Parliament. Subsequently a number of European member state governments began to question their own cloud service provisions, and in some cases banned U.S. providers from offering IT and computing services in their countries.
U.K.-based defense giant BAE Systems in the past year reneged on plans to adopt Microsoft's cloud-based services, citing fears that critical national defense secrets could land in U.S. hands.
The Dutch government is also investigating a potential conflict with third country law in regard to personal citizen passport data. Dutch social-liberal party D66 raised questions in the country's parliament after suspicions arose that U.S. authorities could potentially access Dutch fingerprint and facial scans for passports because the North Holland-based company Morpho is owned by parent company Safran, which conducts systematic business in the U.S.
U.S. jurisdiction 'extends to companies'
Cloud computing is the storing of documents, photos, music, and files online. Governments, in possession of citizen data along with their own national security secrets, are increasingly utilizing cloud services for internal government communications, hosting documents, and enabling the sharing of vast amounts of data between government departments.
For companies, schools, and universities that wish to keep their data in their home jurisdiction -- governments, most of all -- the cloud poses a new set of risks.
Because most major cloud providers, such as Apple, Amazon, Google, and Microsoft, are based in the U.S., the study was focused on the provisions under U.S. law, particularly in reference to the Patriot Act, signed in 2001, and the Foreign Surveillance Intelligence Act, originally signed into law in 1978 and last amended in 2008 by Congress.
The researchers explain that businesses, schools, and universities located outside the United States -- including foreign governments -- that use cloud services offered by a company that conducts business in the U.S. could be forced by U.S. law enforcement to transfer data to U.S. territory for inspection by law enforcement agencies.
"In the U.S. legal framework, there is a legal doctrine called 'extra-territorial jurisdiction.' This implies that cloud providers operating anywhere in the EU, or anywhere in the world for that matter, have to comply with data requests from U.S. authorities as soon as they fall under U.S. laws," said Arnbak.
"These laws, including the Patriot Act, apply as soon as a cloud service conducts systematic business in the United States. It's a widely held misconception that data actually has to be stored on servers physically located in the U.S."
If it is forced to hand over EU-stored data to the U.S., the company could be found in breach of EU law, even if it is covered by both EU and U.S. legal jurisdictions.
"The key criterion in this respect is whether the cloud provider conducts systematic business in the United States, for example because it is based there or is a subsidiary of a U.S.-based company that controls the data in question," the researchers write.
Because non-U.S. residents are not protected from unwarranted searches under the Fourth Amendment, the researchers warn that this "gives the U.S. government entities concerned the statutory power to gather data on a large scale about non-U.S. citizens located abroad. And legal protection under specific U.S. laws applies primarily to U.S. citizens and residents."
However, under FISA -- amended by the Patriot Act in October 2001, just a month after the September 11 terrorist attacks -- foreigners were not the only group immune to unwarranted searches, the Fourth Amendment notwithstanding.
"The Bush administration had intercepted the communications of Americans without obtaining a judicial warrant. The New York Times had carried reports on this from late 2005," the researchers write.
The Patriot Act also added power to FISA which, "enables the FBI to request access to business records for an investigation into espionage and terrorism involving both U.S. and non-U.S. persons."
However, while the researchers warn that U.S. law extends beyond the reach of its borders, figures relating to requests do not exist in the public domain.
The common misconception, according to the researchers, is that FISA gives the U.S. "unrestricted" or "unprecedented" access to data outside the country. FISA warrants do go through a "special court known as the Foreign Intelligence Surveillance Court (FISC)." The role of the court is to, "review the acquisition of intelligence information in this way if U.S. government entities require the assistance of electronic communication service providers for this purpose."
This keeps highly sensitive requests for foreign data, under the premise of keeping terrorism-scale investigations secret, out of the public eye. Because FISA courts hold national security secrets and details of ongoing terrorism investigations, the researchers say the data can't and shouldn't be published.
"Given the nature of intelligence work, it is not possible to gain insight into actual requests for information by the U.S. authorities, other than a description of the general legal framework," the researchers write.
EU citizens 'at risk' from FISA, Patriot Act
While most Americans are aware of the Patriot Act and its wide-ranging provisions for domestic security, its role outside the U.S. border remains widely unknown.
While the researchers focused their efforts on the data protection of cloud users in higher education in the Netherlands, in speaking to CBS News, Arnbak warned that the concern over the ability of third countries accessing data stored in the European Union was not limited to the Netherlands but that it "certainly" extends to the 27 member state bloc, and even outside the European Union.
"The risk of data access by U.S. authorities to cloud data is realistic, and should form an integral part in any decision-making process to move data into the cloud," he said.
Because the Netherlands is a member of the European Union, the country's data protection laws originally stemmed from a wider directive from the European Commission.
Ratified in 1995, the EU Data Protection Directive must have been subsequently implemented into the legal systems of all member states by 1998. Therefore, every EU member state has the same foundation framework for data protection and privacy, allowing data to freely flow across member states' borders, just as EU citizens have the right to do.
Audit Raps FBI On Privacy
"This concerns anyone with an interest in autonomy and control over access to data -- governments, businesses, nonprofits, and consumers alike. That's why the current debate on electronic heath records in the Netherlands is both fascinating and very serious. It appears that nobody has looked into this risk before investing millions in taxpayer money to build these systems," Arnbak said.
He noted that businesses and governments alike, despite the additional costs, should consider in-house solutions instead of moving to the cloud. "If data is processed in-house, institutions will at the very least know of such investigations at an early stage."
Cunningham says, "There remains no credible way -- short, perhaps, of end-to-end encryption with the data provider holding the only key -- to assure confidentiality and security for cloud-stored data, whether stored in the United States or elsewhere."
"Governments and institutions seeking such privacy and security protections should, at least for now, stick to storing their own data or, perhaps, implementing national cloud solutions with robust privacy and security protections."
Because the U.S. government has "ample possibilities to request data from foreign (in this case Dutch) users of the cloud," the researchers claim, "it grants [authorities the ability] to retrieve information on a large scale, including access to complete data sets."
"In other words, these agencies may obtain information not only about a student who could pose a threat to U.S. national security but also about a student who makes an appointment in good faith through e-mail with a person suspected by U.S. authorities of drug trafficking," the researchers assert.
But this also extends outside the Netherlands to countries both in and outside the European Union. "From the U.S. legal perspective, Dutch users of cloud-based computing services therefore enjoy the same degree of [U.S.] constitutional protection as North Koreans," the study says.
However, the U.S. is not alone with laws like FISA or the Patriot Act. The researchers note that such wide-ranging provisions, which can give countries access to cloud-stored data outside their respective jurisdictions, are not limited to the U.S. "Other nation states, including the Netherlands, have comparable provisions in place for access to data in the context of law enforcement and national security."
As an example, the report points to the Dutch Intelligence and Security Services Act, which gives the Dutch security and intelligence services "the power to process the personal data of a wide range of persons." One of the sections of the law specifically carries FISA-like provisions in the Netherlands, which authorize authorities "to carry out, using a technical aid, targeted tapping, reception, recording, and interception of any form of conversation, telecommunication, or data transfer by means of an automated activity, irrespective of where this takes place."
Similarly, the Canadian Anti-Terrorism Act "replicates" much of the provisions in the U.S. Patriot Act. Ontario's information and privacy commissioner, Ann Cavoukian, said in a recent report that the act's provisions are part of the normal data-sharing process between governments.
"You can outsource services, but you cannot outsource accountability," Cavoukian says.
"Legal provisions regulating data access for intelligence and law enforcement purposes will exist in all democracies," Arnbak says.
Cunningham warns that large, multinational, private cloud companies could pose a greater risk to private and sensitive citizen data than governments.
"Many intelligence services around the world, particularly in nondemocratic countries, have no effective legal restrictions whatsoever, and are aggressively collecting massive amounts of sensitive personal, government, and commercially valuable information around the world," Cunningham says, continuing:
"Particularly with the rise of large, lightly regulated cloud data storage providers, private, multinational companies actually may have more access to sensitive, personal data than national governments." Cunningham goes on to say that such firms "assert far more authority to combine and data-mine such data for their own purposes than would the government be permitted under U.S. law."
"And, whether or not such companies would intend to misuse such data, they are far from immune from ill-motivated insiders and external hacking activities by individuals, criminal groups, and foreign governments."
As a result, many countries can also theoretically acquire data stored by companies in another country without a mutual legal assistance request -- used by governments to request help in obtaining evidence from another jurisdiction to assist in investigations in another -- if the company is required by that country's domestic law to assist, in spite of any protection offered by a third country's legal system.
This could include cloud-stored medical data, financial information provided by banks, and business documents or corporate secrets, all the way down to an ordinary user's cloud-stored iTunes music collection or the cloud-stored photos taken on a recent vacation.
Because the U.S. is home to the global powerhouses that run major cloud services -- not limited to Apple, Amazon, Google, and Microsoft -- the research increases the scope of relevance to cloud users. Conversely, the report notes that the company may not have to be headquartered in the U.S. to be supposedly susceptible to a data access request.
"If a company has a subsidiary or branch in the United States, it may be assumed that such jurisdiction exists, but jurisdiction may also exist in other more complex cases," the researchers assert.
Authorities, however, are more likely to be interested in the electronic communications between two or more persons, rather than a citizen's recent holiday photos.
In the case of cloud-stored e-mail, which many businesses, schools, universities, and ordinary citizens use, this can be hosted by an EU-based subsidiary of a U.S.-based parent company. U.S. residents enjoy not only Fourth Amendment protection from unwarranted searches but also additional protection from the Electronic Communications Privacy Act (ECPA) and the Stored Communications Act (SCA), which regulate the U.S. government's access to electronically stored data, such as e-mail, in criminal investigations.
Petraeus scandal developments
One of the strongest legal protections, the researchers note, under the SCA is the provision that requires U.S. authorities to request a search warrant from a judge, based on grounds of reasonable suspicion, if e-mail is less than 180 days old. This law recently came to light after the recent resignation of Gen. David Petraeus, the former director of the Central Intelligence Agency. A warrant from only a federal prosecutor is required to acquire e-mails that are older than six months.
However, if U.S. federal authorities requested foreign citizen data, those citizens would not receive protection under the Fourth Amendment, nor would they receive any protection from the ECPA or the SCA. "The position remains that if a person whose records have been requested is not a U.S. person and is not located in the United States, he cannot invoke the protection of the Fourth Amendment," the research states.
The academics warn that, while in some cases contracts can be offered to cloud customers, these do not override judicial requests by third countries. "The possibility that foreign governments request information is a risk that cannot be eliminated by contractual guarantees."
Did EU laws ever protect against third country snooping?
The EU's Data Protection Directive of 1995 states that EU personal data may be transferred outside the 27 member state bloc only if the transferring country provides guarantees that the data will be given an adequate level of protection.
Data stored in the European Union freely flows to the U.S. so long as the company or government department receiving the data adheres to the EU's Safe Harbor Principles, which were set up between the U.S. government and the European Union after the EU data and privacy laws were first ratified in 1995. The Safe Harbor Principles help U.S. recipients of EU data observe basic EU data protection rules in order to prevent data loss or accidental data disclosure by U.S. companies receiving such data.
The Patriot Act, signed into law in 2001, granted some new powers to U.S. authorities, but it was mainly a "framework law" that amended and strengthened a variety of older laws, such as FISA and ECPA. The 2001 act has since been amended numerous times to extend its powers. FISA, which enables authorities to acquire cloud-stored data in foreign countries and jurisdictions, was first signed into law in 1978, and has also been amended numerous times to keep up to date with current technological trends.
While suggesting that the Patriot Act has bypassed the protection of European data by the EU Data Protection Directive, allowing data to be potentially transferred outside the EU via a U.S.-based company, one former U.S. government lawyer noted that the Patriot Act did not substantially change how the U.S. government acquires data for intelligence purposes.
ZDNet's report suggests that the Patriot Act has "negated" the protection of European data by the EU Data Protection Directive, allowing data to be potentially transferred outside the EU via a U.S.-based company. Politicians in the European Union raised questions over laws that may affect their own nation's legal system.
Cunningham told CBS News that with appropriate judicial or other government procedures, "U.S. law enforcement and security authorities remain, as they were before the Patriot Act, able to lawfully collect both the substance of electronic communications and telephone toll, e-mail, and other business records, both of U.S. persons and those of other countries, without resort to mutual legal assistance or other international agreements and procedures."
"This is particularly true when such data is held by companies physically located in, or with substantial business connections to, the United States," he continues.
U.K., Netherlands raise concerns over cloud legal issues
The issues related to FISA and the Patriot Act notwithstanding, there are already existing agreements and data-sharing arrangements between EU member states and nonmember states such as the U.S. Without them, most Europeans would not be allowed to even step on an airplane bound for the U.S.
Mutual legal assistance (MLA) agreements that conform to EU data protection and privacy laws exist between various nations, in order to assist countries both within and outside the 27 member state bloc with criminal investigations. For instance, the U.S., Australia, or any other country with an MLA agreement with the Netherlands can request data on a Dutch citizen, just as the Netherlands can in return request data on that country's citizens.
"If U.S. government agencies have no jurisdiction over an entity operating in the Netherlands, they may submit a request for mutual assistance under such agreements," the researchers state.
"But in the borderless cloud, in which activities are in the U.S., there is "no clear obligation under U.S. law for the U.S. government to rely on such agreements when seeking access to data on non-U.S. persons."
Also, passenger name record (PNR) data-sharing agreements between the EU and Australia, Canada, and the U.S. not only allow citizens to travel between those countries but also help those authorities fight transnational crime.
PNR data includes personal and sensitive citizen data, such as name, gender, date of birth, and nationality. It can also include "racial or ethnic origin, political opinions, religious or philosophical beliefs, trade union membership or [information] concerning the health or sex life" of the person in question, according to the European Commission, but the report notes that PNR data "rarely contain sensitive data of this kind."
When the EU-U.S. PNR agreement came up for renewal, in 't Veld was appointed the "rapporteur," or the person chosen by the European Parliament to investigate the agreement. After many months of negotiations, with the previously debated EU-Australia PNR agreement set as, in her words, an "acceptable" agreement, in 't Veld ultimately recommended that the European Parliament reject the EU-U.S. PNR deal, citing privacy fears relating to the disclosure of EU citizen data to U.S. authorities.
"The U.S. may also use the data for other, less-explicitly defined purposes such as immigration and border controls," in 't Veld warned in her findings.
Nevertheless, the U.S.-EU PNR agreement passed with a significant minority opposing the deal, but by then in 't Veld had distanced herself from the report in which she recommended the deal be rejected.
"The decision of the European Parliament does not reflect my recommendation. Therefore I choose to distance myself from it," in 't Veld said. If the agreement was not signed, it may have meant "the visa privileges for European travelers to the U.S. fell" -- or the disallowing of EU citizens to travel to the U.S. -- in 't Veld noted.
Lawmakers On NSA Controversy
Beyond the European Parliament, other EU member states are warning their respective parliaments and governments that the reach of third country laws could extend beyond their reach as a result of the borderless "cloud."
The U.K. Parliament recently outlined its plans to move to the cloud, but worries regarding the Patriot Act spurred on two opposition members to question the proposals.
In a recent debate in the House of Commons discussing the cost-efficiency of Parliament, John Thurso, chair of Parliament's Finance and Services Committee, suggested that all parliamentary members should "move to a more cloud-based system." (The full video can be found on the BBC's Democracy Live Web site.)
However, another politician interjected, mentioning that committee members are currently using iPads and saying that they "cannot put information on the cloud on the basis that servers for Apple products are based in the U.S. and therefore covered by the Patriot Act."
Thurso retorted: "The committee is not yet engaged on the Patriot Act." Parliament member Angela Eagle, who was responsible for the early planning of the 2011 census, also questioned Thurso to "ensure when we do get a cloud finally, its storage will be in the U.K."
In the Netherlands, the government is under increasing scrutiny over unrest surrounding the country's electronic patient records system.
The patient records are operated by a Dutch subsidiary of U.S. parent company CSC, though the data is stored on servers in the Netherlands. However, VZVZ director Edwin Velzel, whose company is behind the setting up of the system, told Dutch television earlier this month that unless CSC can give assurances that it is not subject to the Patriot Act, the contract will be withdrawn.
Arnbak highlighted possible problems with the Dutch passport system. He told CBS News in an e-mail: "In order to obtain a passport, all Dutch citizens need to provide fingerprints to the government. Morpho, a company that falls under U.S. jurisdiction, was contracted to process these fingerprints, which are thus stored somewhere in the cloud and within reach of U.S. authorities under the Patriot and FISA Acts."
"When this hit the news in the Netherlands, it logically caused considerable social unrest," he said.
Dutch Home Affairs Minister Liesbeth Spies said in a briefing to members of the Dutch parliament that she could not rule out U.S. authorities accessing Morpho's database of passport data.
In 't Veld told CBS News that the governments who have been confronted by such issues "tend to deny the problem, or -- when they can no longer deny it -- just duck the issue by making vague promises about 'speaking to the U.S. authorities.'"
"Frankly, I wouldn't know what there is to discuss. The only relevant question is: Do European and [member state] authorities feel responsible for enforcing EU law on EU territory, and protecting EU citizens, or do they not?"
Europe's next steps: Secure the European cloud
The potential conflicts between U.S. antiterror laws and EU data protection law, as described by the researchers at the University of Amsterdam, could be solved with the upcoming EU Data Protection Regulation, which was proposed by the European Commission in January.
Speaking in the European Parliament's upper house chamber earlier this year, EU Justice Commissioner Viviane Reding noted there was not enough clarity in the existing data protection and privacy laws, and that the final say on any international disputes regarding the impact of third country legislation on EU laws would be up to the International Court of Justice, the so-called "World Court," in The Hague.
But she said she was confident that the draft Data Protection Regulation, published this past January, would "bring further legal clarity."
Some members of the European Parliament remain skeptical that the new "one size fits all" law will not offer sufficient protections against U.S. or any other third country law.
In 't Veld, who has been particularly vocal in the European Parliament regarding data protection and concerns of third country law impacting European citizens, told CBS News that the European Commission continues to deny the potential conflict between the two continents.
"I do not think it will lead to a change in policies in the short term. The problem is not that governments and the Commission are not aware of the problem. We have brought it to their attention ad nauseam. The real problem is they have no interest in addressing it."
In 't Veld noted in a 2011 letter to Reding that, "EU based companies are currently facing U.S. subpoenas under the Patriot Act." She added: "They are obliged to submit data stored in Europe to U.S. authorities, thereby probably violating EU laws." Because these firms have operations in the U.S., she described it as "very difficult" for them to refuse to comply with a U.S. subpoena.
"I really wonder if the authorities will be just as lax when they realize other countries can and will do the same -- China, for example. The passivity of Commission and [member state] governments sets a very bad precedent. They are failing their citizens."
A European Commission representative told CBS News in an e-mailed statement: "The high standards which we give to our citizens must also be transferred when there is an exchange of data with third countries."
"We in the Commission take this question very seriously, because the Commission believes and supports the principle that, in international public law, a legal act which is enacted by a third country cannot be directly and automatically applied in the territory of the EU unless -- exceptionally -- Union law or Member State law explicitly recognizes the facts of such an act in their respective jurisdiction."
The Commission also explained that existing legal channels -- such as mutual legal assistance requests -- must be used:
"No legal acts of a third country as such can legally overrule the relevant EU legislation or Member State legislation, and this includes data protection rules. Any processing of personal data in the EU has to respect the applicable EU data protection law. If, for example, a U.S. law enforcement authority requires information from companies operating in the European Union, whatever the nationality of those companies, they have to use existing channels of cooperation and mutual legal assistance agreements."
"This issue also applies when personal data are transferred by an EU company to a company in the U.S. and when the data are subsequently processed for law enforcement purposes."
Arnbak argues that a real solution to the concern over third country laws can be found only on an international legal and political stage.
"It is important to realize that government access to cloud data is not a data protection issue," Arnbak says. "Having to comply with a data access request from the government is not something that you can exclude yourself from in a legal contract: you either comply as a cloud provider, or you face prosecution."
"The fact that the important cloud providers of today will have to comply with U.S. legal requirements, while non-Americans living outside the U.S. cannot claim the legal protection that their domestic law provides for, constitutes a gap in legal protection that can only be solved by governments engaging with each other at the international level."
Arnbak resonated in 't Veld's concerns about the cloud. He said that the European Commission should be "open and frank about the wide gap in legal protection for Europeans in the U.S. cloud and either demand that these concerns are addressed through an EU-U.S. approximation of laws, or stimulate alternatives that lower the dependency of European customers on U.S. entities."
