VASQUEZ, Daniel; CERPA, Narciso  e  ANGLES, Renzo. A secure discussion system with anonymous participation through Web services. Ingeniare. Rev. chil. ing. [online]. 2013, vol.21, n.1, pp.82-98. ISSN 0718-3305.  http://dx.doi.org/10.4067/S0718-33052013000100008.

A challenge for democratic deliberation in a computing environment is to provide security in the process, both for the individual citizen and the social group. In this regard, it is important to provide guarantees of protection to the citizens so as not to affect their freedom of expression and security on the exchange of messages, so they are reliable for all participants. As part of this project a discussion system has been designed and built that allows users to exchange opinions safely, through the application of cryptographic techniques. The system allows multiple levels of security and identification. It allows the participation identified through the use of digital signatures and certificates. Furthermore, it implements a scheme of anonymous participation by signing messages using credentials obtained from a blind signature process. Also security attributes are applied to ensure to ensure the integrity, confidentiality and non-repudiation of these. The discussion system was built embedded in a Web services platform designed to provide functionality to support digital democracy.

Palavras-chave : Deliberative democracy; cryptography; digital signature; blind signature; anonymity; freedom of speech.
