Summary: | Aiming at the information security problem of sharing images on social platforms, a selective region of interest(ROI) image encryption scheme based on YOLO v4 and hybrid chaotic map encryption is proposed.By utilizing YOLO v4,the uploaded image is automatically detected and the candidate bounding boxes to be encrypted are provided.Then the image areas selected by user are encrypted with the proposed hybrid encryption algorithm combining cosine and polynomial mapping, so that only legally authorized users can access the sensitive information of the shared image.Through the secret key issuing and authorization mecha-nism, the protection of sensitive information of the image forwarded by a third party is realized.Statistical and security analysis results prove that the proposed scheme can resist various attacks, and the processing speed can meet the real-time needs of online users. |
