Abstract

The security of multimedia content such as images while transmission is a cause of concern in current times. Traditional watermarking techniques help in identification of source as well as maintaining patient metadata for biomedical images. Similarly, traditional image encryption techniques allow privacy of patients. There is a need for a two-layer security approach with joint watermarking and encryption, to improve over contemporary methods. This paper presents comparative analysis of various joint encryption and watermarking algorithms of biomedical images to fin d the best pair of algorithms based on previous research. Comparative results also indicate that joint encryption and watermarking algorithms are suitable for security of biomedical images.
