Problems solved by technology

[0002] Smartphones are no longer just a tool for calling and sending text messages. They have been widely used in life and work like personal computers. Due to their easy portability, they have gradually become a necessary tool for personal mobile office and work. A series of corresponding security issues have also given rise to Mobile phone users bring confusion and worry, such as mobile phone loss, information leakage, virus invasion, information fraud, etc., will bring inconvenience or loss to mobile phone users

Especially in mobile banking, mobile payment, mobile transfer, and mobile shopping, account information leaks frequently cause financial losses. Mobile phone use rights and information protection have become urgent problems for mobile phone users. Common security solutions include power-on password protection. SD card digital authentication, mobile soft certificate application and other technical measures to protect mobile phones, power-on password protection method is relatively weak, sd card digital authentication method has high cost and poor usability. The security of mobile soft certificates also has a fatal loophole of being copied. The Bluetooth key separated from the mobile phone has become an optional solution for smartphone security products. Similarly, the openness of Bluetooth wireless communication, its communication security and identity authentication are another issue. new challenge
