In this paper we show the potential of two new features as powerful anti-spoofing measures for face-voice person authentication systems. The features based on latent semantic analysis (LSA) and canonical correlation analysis (CCA), enhance the performance of the authentication system in terms of better anti-imposture abilities and guard against video replay attacks, which is a challenging type ...

As well as traditional distributed systems, a SoC and its network are susceptible to attacks to their security properties. This paper presents a survey that was conducted in order to identify the techniques that have been applied to ...
