Privacy is one of the most concerned issues in the information era, and it is especially significant in the study of mathematical science ethics. When it comes to privacy protection, we hope to achieve a state where all parties or different users participating in the game can achieve their maximum benefits while protecting their privacy. Information providers should also act in their best interests without a loss of user privacy. Only in this scenario will privacy be protected, and quick identification at the commencement of privacy leaks, the most straightforward remedy, is critical to privacy prevention.
