Personalized Multimedia (PMM) services are the emerging area in multimedia technology. A PMMservice is a multimedia service provided according to the users personal profile which typically includes individual preferences, keeping the technical constraints of mobile device in use and the operating environment. We have proposed in [2], a transaction-based authentication scheme for PMM applications using cognitive agents. The proposed approach dynamically deploys authentication challenges based on mobile transaction sensitivity and users transaction time behaviors. This paper provides performance analysis of the authentication scheme in terms of authentication delay and cost. The performance analysis shows that, there is a considerable reduction in security cost compared to regular session based authentication schemes. By combining transaction based authentication with behavior analysis authentication attacks can be effectively identified.
