Protecting Privacy in Surveillance Systems via Selective Video Encryption

The "Privacy Preservation in Surveillance Video Using Selective Encryption" study addresses the issue of privacy in surveillance videos. Video surveillance systems are widely deployed in many public places such as banks, supermarkets, airports, roads, and residential areas. However, the privacy of individuals in these videos is a major concern. The proposed system aims to conceal faces while not interfering with the observation and recognition of human activities. The system uses selective encryption to encrypt only the face region of the frames while other parts of the frame are retained as it is. The proposed method is reversible for revealing faces whenever needed to the authorized person using proper secret keys. The project also aims to ensure the security of the encryption algorithm used and provide a user-friendly interface for ease of use. Overall, this study aims to provide an efficient and scalable solution to the problem of privacy in surveillances.
