Encryption method and authentication method based on magnetic resistance sensor, and mobile terminal and server

Abstract

The invention discloses an encryption method and an authentication method based on a magnetic resistance sensor, and a mobile terminal and a server. The encryption method comprises the following steps: A, acquiring a password input by a user and collecting encryption characters corresponding to password units; and B, transmitting the password body and the encryption characters in preset directions corresponding to the password units to a server. Sensing information acquired by a magnetic resistance sensor is provided as encryption characters of the password units of a traditional password. When a traditional text password is used, even if a user chooses to keep the password, the accuracy of user identity can be verified conveniently and safely for key operations. Action memorization is easier and more confusing than character memorization. By combining actions and characters, the importance of text passwords can be weakened, the influence of shortcomings can be reduced, and the security can be strengthened.

Description

technical field [0001] The present invention relates to the field of security assurance of mobile terminal equipment, and more specifically, relates to an encryption and verification method based on a magnetoresistive sensor, and a mobile terminal and a server terminal. Background technique [0002] Due to the advancement of science and technology and the improvement of living standards, mobile terminals bring us convenient, fast and rich experiences in daily life, but also have potential safety hazards. Passwords are an important means for us to verify user identities. Although some passwords have added security measures, it is still uneasy to frequently enter passwords in public places. Lawbreakers take long-distance cameras, causing people to suffer property losses due to peeking at passwords, and it is difficult to provide evidence for claims in addition to property losses. At the same time, on the one hand, the password is too simple and direct, not confusing, and easy...

[0002] Due to the advancement of science and technology and the improvement of living standards, mobile terminals bring us convenient, fast and rich experiences in daily life, but there are also potential safety hazards

Passwords are an important means for us to verify user identities. Although some passwords have added security measures, it is still uneasy to frequently enter passwords in public places. Lawbreakers take long-distance cameras, causing people to suffer property losses due to passwords being peeped, and it is difficult to claim proof for property losses

At the same time, on the one hand, the password is too simple and direct, not confusing, and easy to watch, imitate and copy operations; on the other hand, the text password is easy to record, and needs to be changed frequently to ensure security, but it is not easy to remember, resulting in more people who choose to remember the password
