Abstract
Method, system and apparatus for securely sharing audio-video data based on full anonymous privacy. The system encapsulates the original audio-video data and uses an obfuscation algorithm to protect service information, such that the requirements of audio-video data sharing are met, and the privacy of data is increased; meanwhile, determines shareable audio-video data by calculating the intersection of the obfuscation sets, such that the accuracy of data access is ensured. In addition, the system further uses an encryption algorithm to protect an identity and permission of a recipient, categorizing information and grading information, only sends data that the data recipient has permission for, improving security and reducing system resources. The system the requirements of audio-video data sharing and protects the privacy and security of the audio-video data, prevents the leakage of sensitive information, and thus improves the security of audio-video data sharing.
