Abstract

Real-time video encryption is a critical need in today’s digital era. With the proliferation of online activities like streaming, virtual meetings, and transmission of sensitive data, the demand for secure data transmission is at an all-time high. In this paper, a new algorithm is proposed for encrypting MPEG-4 video frames. This algorithm involves encrypting the DCT values of a macroblock XOR-ed with the encryption key to significantly enhance the encryption speed and robust security while reducing the computational cost.
