With the development and progress of the economy and society and the arrival of the network era, we have fully enjoyed the convenience brought by the information age, and the influence of information on people's lives have become increasingly prominent. However, the risk of improper use of personal information is increasing, such as the credit card theft, mobile phone fraud, and so on. The serious leakage of personal information not only involves personal reputation, but also disturbs the normal order of production and life. Therefore, this paper analyzes the existing countermeasures to prevent the leakage of personal information on the Internet, and on this basis, puts forward a more perfect solution, and uses domestic cryptography technology to realize the omni-directional protection of personal information security on Internet.
