Background technique

Password, as the patron saint of information security, is an important guarantee for property protection and information security. At present, the widely used password systems mainly include digital passwords and biological information passwords such as fingerprints, facial recognition, and DNA. Traditional digital passwords are very easy to be peeped and used by others, resulting in property loss and personal information theft cases are not uncommon. Mobile phones have become a part of people's lives, and they are often used to store personal information, shop online, etc. Therefore, the security of the mobile phone password system is very important. At present, even though pattern passwords and fingerprint passwords have been used in mobile phones, they still have not solved the problem of how to prevent others from cracking the passwords by using cameras, peeping, etc., and there is still a problem that fingerprint passwords cannot be changed once they are copied. How to solve the anti-peeping and anti-cracking security problems of the mobile phone password system itself is the root of solving the security of mobile phone passwords.
