Security in real time multimedia data based on generalized keys

Abstract

In this paper, address the problem of encryption/decryption regions of interest in a video sequence for the purpose of security in video data. The proposed an efficient solution based on 3D encryption/decryption based. More specifically the videos files breaks different frames as 2D based digital images, after 2D based images encrypt/decrypt by the 2D generalized algorithms. The simulation results show that the mechanism can be successfully applied to obscure information in regions of the interest in the scene which provides the different level of security. Further, the keys values are flexible and allow choosing different types for security purpose.
