AN ENCRYPTED VIDEO SHARING FOR SENSITIVE BASED SECURE COMMUNICATION

Various multimedia technologies, more and more multimedia data are generated and transmitted in the medical, commercial, and military fields, which may include some sensitive information which should not be accessed by or can only be partially exposed to the general users. Numerous multimedia encryption techniques have been presented in the literature, and some of them have even been implemented in actual products. However, cryptanalytic work has demonstrated that the majority of these schemes contain security flaws and other vulnerabilities. To hide privacy from sensitive areas, different cryptographic and ROI extraction techniques are presented. Each ROI derived from frames will be organized as binary blocks and then set as the initial states for a LCA (Lightweight Cryptography Approach) proposed. Thereafter, the LCA uses its reversible rules and simple transformations model for state transitions. The final state data of the LCA is extracted and saved as the encrypted ROI. All ROIs are encrypted independently. The ROIs are encrypted and stored at the camera side for an on-demand service required by the authenticated users, which makes the proposed method both effective and efficient. ECC-based approach is devised to encrypt ROIs for privacy protection in surveillance videos. This proposed work describes a proposed hybrid model using public key Elliptical Curve Cryptography (ECC). This approach provides more security than other encryption methods.
