The cost of protecting privacy in multimedia applications
Khalil El‐Khatib · 2008
The concept of protecting the privacy of the users of multimedia applications is a new and interesting research area, which has many challenges. While protecting the privacy while using traditional communication services was provided by trusted telecom provider, the situation today is different, with the insecure Internet becoming an important communication network. Current Internet telecommunication protocols do not address the issue of protecting the user's privacy, which became one of the key factors for determining the future of multimedia communications. In previous work, we have designed a framework for the exchange of user's preferences, and presented a negotiation protocol for negotiating the acceptable configuration parameters for each user while protecting the privacy of the exchanged information. In this paper, we will present a review of the protocol and study its complexity; we will argue that the cost of protecting the user's privacy can be used a quality of service differentiator between different service providers.
