This is the fourth in a series of posts mapping global surveillance challenges discussed at EFF's State Surveillance and Human Rights Camp in Rio de Janeiro, Brazil. This article has been co-written with Elonnai Hickok — Centre for Internet and Society India, and a speaker at EFF's Camp.

States around the world are faced daily with the challenge of protecting their populations from potential and real threats. To detect and respond to them, many governments surveil communication networks, physical movements, and transactional records. Though surveillance by its nature compromises individual privacy, there are exceptional situations where state surveillance is justified. Yet, if state surveillance is unnecessary or overreaching, with weak legal safeguards and a failure to follow due process, it can become disproportionate to the threat—infringing on people's privacy rights.

Internationally, regulations concerning government surveillance of communications vary in approach and effectiveness, often with very weak or nonexistent legal safeguards. Some countries have strong regulations for the surveillance of communications, yet these regulations may be largely ineffective or unenforceable in practice. Other countries have no legal safeguards or legal standards differing vastly according to the type of communication data targeted. This is why, EFF organized at the end of last year a State Surveillance and Human Rights Camp in Brazil to build upon this discussion and focused on how states are facilitating unnecessary and disproportionate surveillance of communications in ways that lead to privacy violations.

State-Mandated Identity Verification

In 2012 the Constitutional Court in South Korea declared that country's "real-name identification system" unconstitutional. The system had mandated that any online portal with more than 100,000 daily users had to verify the identity of their users.1 This meant that the individual has to provide their real name before posting comments online. The legal challenge to this system was raised by People's Solidarity for Participatory Democracy (PSPD)'s Public Law Center and Korean Progressive Network—Jinbonet among others.

Korea University professor Kyung-shin Park, Chair of PSPD's Law Center told EFF that portals and phone companies would disclose identifying information about six million users annually—in a country of only 50 million people. The South Korean Government was using perceived online abuses as a convenient excuse to discourage political criticism, professor Park told EFF:

The user information shared with the police most commonly has been used by the government to monitor the anti-governmental sentiments of ordinary people. All this has gone on because the government, the legislature, and civil society have not clearly understood the privacy implications of turning over identifying information of individuals.

The decision by the South Korean Constitutional Court to declare the "real identification system" unconstitutional was a win for user privacy and anonymity because it clearly showed that blanket mandates for the disclosure of identifying information, and the subsequent sharing of that data without judicial authorization, are a disproportionate measure that violates the rights of individuals.2

States Restrict Encryption and Demand Backdoors

Some States are seeking to block, ban, or discourage the use of strong encryption and other privacy enhancing tools by requiring assistance in decrypting information. In India service providers are required to ensure that bulk encryption is not deployed. Additionally, no individual or entity can employ encryption with a key longer than 40 bits. If the  encryption equipments is higher than this limit, the individual or entity will need prior written permission from the Department of Telecommunications and must deposit the decryption keys with the Department.3 The limitation on encryption in India means that technically any encrypted material over 40 bits would be accessible by the State. Ironically, the Reserve Bank of India issued security recommendations that banks should use strong encryption as higher as 128-bit for securing browser.4

In the United States, under the Communications Assistance for Law Enforcement Act, telecommunication carriers are required to provide decryption assistance only if they already possess the keys (and in many communications system designs, there's no reason carriers should need to possess the keys at all). In 2011, the US Government proposed a bill that would place new restrictions on domestic development or use of cryptography, privacy software, and encryption features on devices. The bill has not been adopted.

Allowing only low levels of encryption and requiring service providers to assist in the decryption of communications, facilitates surveillance by enabling States easier access to data and preventing individuals from using crypto tools to protect their personal communications.

States Establish Blanket Interception Facilities

In Colombia, telecommunications network and service providers carrying out business within the national territory must implement and ensure that interception facilities are available at all times to state agencies as prescribed by law. This is to enable authorized state agencies to intercept communications at any point of time. In addition to providing interception facilities, service providers must also retain subscriber data for a period of five years, and  provide information such as subscriber identity, invoicing address, type of connection on request, and geographic location of terminals when requested.

Though Colombia has put in place regulations for the surveillance of communications, these regulations allow for broad surveillance and do not afford the individual clear rights in challenging the same.

Conclusion

The examples above demonstrate that, although state surveillance of communications can be justified in exceptional instances, it leads to the violation of individual privacy when implemented without adequate legal safeguards. Clearly there is a need for international principles articulating critical and necessary components of due process for the surveillance of communications. Those strong legal safeguards are necessary not only in countries that don't have laws in place, but also in countries where laws are lacking and fail to adequately protect privacy. Last year, EFF organized the State Surveillance and Human Rights Camp to discuss a set of International Principles on State Surveillance of Communications, a global effort led by EFF and Privacy International, to define, articulate, and promote legal standards to protect individual privacy when the state carries out surveillance of communications.
