More Information
Summary:The invention discloses a privacy protection system and method for target search through an Internet of Things camera, and the method comprises the steps: allowing a requester and a worker to process an image and a video locally on a mobile device, so as to extract the face information of a target and the face information of a bystander; in order to protect the privacy of the target and the spectators, encrypting the face information of the target and the spectators and then sending the encrypted information to the server; searching a target on encrypted information by using a homomorphic encryption technology based on privacy set intersection; after matching the target face and the detected face, employing a PSI base protocol-careless transmission to allow a requester to receive an image while bystanders of all other captured images are not revealed. In addition, the face image of the target employee is not affected by the employee and the participant. Owing to the high computational overhead of primitives,
