Privacy has been a concern for humans long before the explosive growth of the Internet. The advances in information technologies have further increased these concerns. This is because the increasing power and sophistication of computer applications offers both tremendous opportunities for individuals, but also significant threats to personal privacy. Autonomous agents and Multi-agent Systems are examples of the level of sophistication of computer applications. Autonomous agents usually encapsulate personal information describing their principals, and therefore they play a crucial role in preserving privacy. Moreover, autonomous agents themselves can be used to increase the privacy of computer applications by taking advantage of the intrinsic features they provide, such as artificial intelligence, pro-activeness, autonomy, and the like. This article introduces the problem of preserving privacy in computer applications and its relation to autonomous agents and Multi-agent Systems. It also surveys privacy-related studies in the field of Multi-agent Systems and identifies open challenges to be addressed by future research.

“…However, agents cannot hold more than one pseudonym, i.e., principals should use a different agent each time they want to use a different pseudonym (similarly to what is proposed by Cissée and Albayrak (2007) explained above). Warnier and Brazier (2010) also present a mechanism for the AgentScape AP that offers pseudonymity by means of what they call handlers. Handlers are pseudonyms that agents can use to send/receive messages to/from other agents.…”

Privacy is of crucial importance in the era of global connectivity in which everything is interconnected anytime and everywhere, with almost 2 billion worldwide users with connection to the Internet. Indeed, most of these users are concerned about their privacy. These concerns also apply for the new emerging research fields in computer science such as Multi-agent Systems. A Multi-agent System consists of a number of agents (which can be intelligent and/or autonomous) that interact with one-another. An agent usually encapsulates personal information describing its principal (names, preferences, tastes, credit card numbers, etc.). Moreover, agents carry out interac-XIII agentes. Además, proporcionamos una infraestructura de agentes segura, para que una vez que un agente decide revelar un atributo a otro, sólo esteúltimo sea capaz de tener acceso a ese atributo, evitando que terceras partes puedan acceder a dicho atributo. Para evitar el procesado de información personal proponemos un modelo de gestión de las identidades de los agentes. Este modelo permite a los agentes la utilización de diferentes identidades para reducir el riesgo del procesado de información. Además, también describimos en esta tesis la implementación de dicho modelo en una plataforma de agentes. XIV Contents Contents XV List of Figures XIX List of Tables XXI In the second part of the twentieth century, Alan Westin defined privacy as "the claim of individuals, groups, or institutions to determine for themselves when, how, and to what extent information about them is communicated" (Westin, 1967). This is what is currently known as the informational self-determination right (Rannenberg et al., 2009). The concept of informational self-determination changed the right to privacy from the right to be let alone to its current incarnation as a means to limit the abuse of personal data (Schermer, 2007). Informational self-determination represents today's European understanding and regulation of privacy in the context of information and communication technology (EU Directives 95/46/EC, 45/2001/EC, and 2002/58/EC). Despite all these regulations, as the Internet has no governing or regulating body, privacy breaches are still possible. Nowadays, in the era of global connectivity (every-1.5.
