Selective Video Encryption using Harmony Search

To prevent video from unauthorized access and fabrication, the video should be encrypted before sending them on the unsecure network. Traditional method of encryption like AES, DES are not suitable for heavy multimedia objects like videos of conferences etc. due to their high computational complexity and restricted size of the key. We propose a methodology of selective encryption of video using keys generated by harmony search a meta-heuristic artificial intelligence technique. We perform selective encryption to reduce encryption time and encrypt on potential confidential information. We compared the efficiency of the algorithm using entropy and found that proposed technique is suitable for video encryption.
