Securing Surveillance Data Using Incremental Cryptography

Incremental cryptography is applicable for an environment wherein the data going through cryptographic changes are modified variants of data which have previously gone through similar cryptographic changes. We implemented a secure surveillance image encryption technique using incremental cryptography. Surveillance systems are generally used for real-time abnormal event detection and autonomous video analysis. Video and real-time images captured by surveillance cameras often contain personally identifiable information, which must be protected by privacy, and sometimes contains sensitive information, such as surveillance locations. Here we consider surveillance images which can exploit the verifiable truth that constant video frames generally have only minor differences. A novel incremental symmetric encryption technique is proposed on this paper. Using incremental encryption, it is possible to rapidly refresh the computational result for a newly updated photo. Thus we can reduce the time complexity. Significant hypothetical consideration has been given to major cryptographic primitives such as digital signatures and message authentication code. The meaning of protection and security has been explored in various works. In this investigation, the attention is on incremental encryption to see how it can assist securing surveillance information.
