Abstract

Selective encryption of visual data and especially MPEG has attracted a considerable number of researchers in recent years. Scalable visual formats are offering additional functionality, which is of great benefit for streaming and networking applications. The MPEG-2 and MPEG-4 standards provide a scalability profile in which a resolution scalable mode is specified. In this paper we evaluate a selective encryption approach on the basis of our hierarchical MPEG video codec.
