Secure data retention of call detail records

Abstract

In today's world communication is relying heavily on electronic means, both for voice and other native data. All these communication sessions leave behind journaling information by the very nature of the underlying services. This information is both sensitive with respect to user's rights and important for law enforcement purposes, so proper storage and retrieval techniques have to be taken into consideration. The paper discusses such techniques in relation with recent EU recommendations and suggests some methods for achieving good performance while preserving the required security levels. © 2006-2010 by CCC Publications.
