New types of legislation concerning electronic surveillance of communications 1. Data retention of traffic data 2. Signal intelligence (strategic monitoring)

Changes in Our SocietyTechnological changeUntil the end of the 1990s satellites were the main medium for international communication. Now it is fiber optics in cables controlled by private companies.Shift in Threats Relevant for National SecurityThe perceived threat from the Soviet Union has been replaced with vague threats such as terrorism, international criminality, migration, environmental threats and financial imbalancesNew Legal DemandsThe European Convention on Human Rights requires that interferences in the private life and family has a legal basis (article 8)PrivatizationTelecom operators were previously state-owned and controlled. Now they are private companies whose priority is to safeguard the interests of their customers, not the interests of the state 4

Signal Intelligence- why legislation?Considering the changes in the 1990s:The technological change and privatization creates a need to adopt legislation or other binding measures that obligates the private operators to surrender communication to the State. This makes the existence of previously top secret surveillance public knowledgeThe shift in perceived threats creates a need to expand the mandate or codify an already expanded mandate of signal intelligence organizations The public knowledge about this surveillance and new legal demands creates a need for legislation protecting privacy 5

Data retention - why legislation?Communication providers have stored traffic data (who is phoning who and when) about the phone calls of their customers for billing purposes. Law enforcement agencies have used such data in order to detect, prevent and investigate crimeNowadays, consumers are turning to flat-rate subscriptions and voice over IP-services (for example Skype). Thus, there is no need to retain traffic data for billing purposes.Law enforcement agencies still want/need traffic data. 6

Traffic analysis and social network analysis We humans leave electronic footprints after us, in the form of credit card payments, visits to websites, records of phone calls and e-mail (communication data). Imagine that somebody could collect everything and process it through a powerful computer. With the right tools one could find patterns that in detail describe what groups and networks you belong to. Such techniques are referred to as traffic analysis and social network analysis 7

With traffic analysis social networks may be identified A communication pattern can depict relations between individuals, Organisations, websites, etc with purpose of charting the social networks, position of power, views and other personal data about an individual. The actual message is less important than the information about the sender, recipient, the time of transaction, and means of communication. Knowledge about the communication pattern and thus the social network of person is often enough Individual 8

U.S. National Research Council, report October 2008 “Protecting Individual Privacy in the Struggle Against Terrorists: A Framework for Program Assessment”

Two general types of data mining techniques • 1. Subject-based data mining • 2. Pattern-based data mining • U.S. National Research Council“Protecting Individual Privacy in the Struggle Against • Terrorists: A Framework for Program Assessment”

Subject-based data mining Subject-based data mining uses an initiating individual or other datum that is considered, based on other information, to be of high interest, and the goal is to determine what other persons or financial transactions or movements, etc., are related to that initiating datum. U.S. National Research Council

Pattern-based data mining Pattern-based data mining looks for patterns (including anomalous data patterns) that might be associated with terrorist activity—these patterns might be regarded as small signals in a large ocean of noise. U.S. National Research Council

When to use the two different techniques In the case of the decentralized group, subject-based data mining is likely to augment and enhance traditional police investigations by making it possible to access larger volumes of data more quickly. Furthermore, communications networks can more easily be identified and mapped if one or a few individuals in the network are known with high confidence. By contrast, pattern-based data mining may be more useful in finding the larger information footprint that characterizes centrally organized terrorist groups. U.S. National Research Council

Utility of pattern-based data mining The utility of pattern-based data mining is found primarily if not exclusively in its role in helping humans make better decisions about how to deploy scarce investigative resources, and action (such as arrest, search, denial of rights) should never be taken solely on the basis of a data mining result. Automated terrorist identification through data mining (or any other known methodology) is neither feasible as an objective nor desirable as a goal of technology development efforts. U.S. National Research Council

Panopticon (Bentham) Panspectron (Delanda) “There are many differences between the Panopticon and the Panspectron being assembled at the NSA. Instead of positioning some human bodies around a central sensor, a multiplicity of sensors is deployed around all bodies: its antenna farms, spy satellites and cable-traffic intercepts feed into its computers all the information that can be gathered. This is then processed through a series of “filters” or key-word watch lists. The Panspectron does not merely select certain bodies and certain (visual) data about them. Rather, it compiles information about all at the same time, using computers to select the segments of data relevant to its surveillance tasks.”

DiscussionBased on the material distributed, discuss for 15 minutes:1. When does the interference with privacy occur in relation to systems of mass surveillance of electronic communication? 2. How does the American system differ from the legal regime under ECHR in its approach to the content/non-content distinction? 3. In the country you come from, do you have any regulations concern signal intelligence/strategic monitoring/surveillance for intelligence purposes? If not, does your country still have a state agency similar to the NSA, GCHQ, BND and FRA? 4. Is it appropriate to involve courts in issues concerning the implementation of policies on national security? 16

Defining content and traffic dataAs opposed to the content of a message, traffic data is the information used by the communication network to deliver the message to or from the user. In a telephone network, traffic data will reveal the number dialed (“to”), the originating number (“from”), the time of the call, and its duration. In the internet context, traffic data will similarly reveal the “to” and “from” e-mail address, the instant message to and from account names, and the other administrative information the computers generate in the course of deliveryCompare with Orin Kerr: content and envelope information 17

Four fields of legislation International communication N/A Signal Intelligence Act (2008:717) 1. Chapter 27 of the Code of Judicial Procedure 2. Chapter 6 section 22(3) of the Electronic Communications Act (2003:389) 3. Act on measures concerning certain serious crimes (2008:854) 1. Act on measures to prevent certain serious crimes (2007:979) 2. Chapter 6 section 22(3) of the Electronic Communications Act (2003:389) Domestic communication Preliminary Investigation Intelligence 18

EU Data Retention Directive1. Data is retained for periods of not less than six months and not more than two years from the date of the communication2. The data retained purports to the questions who was communicating with who, when the communication occurred, where was the communicating parties and what type of communication used. 3. No content data may be retained for the purpose of the directive.4. The access for national authorities to the data is to be regulated through domestic law 19

Summary of the legislation adopted 18 June 2008:IT- and telecom operators are obligated to transfer all communication in cables crossing Swedish borders to nodes controlled by the StateThe Defence Radio Establishment will intercept communication and collect data at the nodes (signal intelligence)

Review Mechanisms

Information life cycle • 1. Interception of messages and traffic data (meta data) • 2. Processing • i) Traffic analysis of traffic data (who is communicating with who) • ii) Cryptanalysis • iii) Analysis of the content of messages • 3. Analysis with the use of other sources, for example Open Source Intelligence (OSINT) • 4. Report to client 4. Method – what is signal intelligence?

1. Fairly small amounts of messages are intercepted and processed • Example from Germany, judgement of the First Senate of 14 July 1999, para. 89 : • The capacity of the Federal Intelligence Service (BND) permits the screening • of approximately 15,000 acts of telecommunication per day out of a total of • approximately 8 million telecommunications contacts between Germany • and foreign countries. The material and personal resources of the Federal • Intelligence Service, however, are not sufficient to evaluate all contacts. • Approximately 700 fall under the area of application of the G 10 Act. Only • these acts are selected with the help of the search concepts. • About 70 of them are examined more closely by employees of the Federal • Intelligence Service. • 2. Traffic data (meta data) relating to all or large amounts of commun- • ication is stored by the Defence Radio Establishment in a database (Titan) • Example from the USA: The NSA Call database contains 1,9 trillion records which • include the records of tens of millions of Americans 5. Scope of Surveillance

To consider… • Is this kind of data collection and surveillance… • Consistent with the right to privacy? This is both a human right and a constitutional right. • Efficient? • Proportional? • Confident and reliable in the sense that it provide accurate intelligence and not false alarms?
