Terminal equipment and method for encrypting user information

Abstract

The invention discloses terminal equipment and a method for encrypting user information. The terminal equipment comprises an encryption chip and a terminal main body, wherein the terminal main body is used for acquiring the biological information and private information of a user; and the encryption chip is used for encrypting the private information of the user by using biological identification information as a key and using an encryption algorithm, sending encrypted information to the terminal main body, and storing the encrypted information. By adoption of the technical scheme, a mobile internet device (MID) can change a display policy according to different external lighting environments, so that the satisfaction of visual sensory of the user is improved, and the performance of products is improved. A hardware solution of the encryption chip is superior to a software method in terms of both speed and performance. By adoption of a biological identification technology, the user does not need to memorize any password; and operation processes of encryption, decryption, display and input are finished inside the encryption chip without adoption of a mobile phone, so that information leakage caused by a virus or Trojan in the mobile phone is avoided.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a terminal device and a user information encryption method thereof. Background technique [0002] People live in modern society and deal with different types of passwords every day, such as power-on passwords of work computers, passwords of bank credit cards, login passwords of personal e-mails, passwords of various registration websites, passwords of online banking, securities trading passwords, etc. , it can be said that we live in an environment surrounded by passwords. Although the length, number of digits, and types of each password are different. But any kind of password disclosure or loss will cause huge losses to users. [0003] At present, most users use some numbers or names that are special to themselves as passwords, such as birthdays, phone numbers, ID numbers, names, etc. Moreover, in order to make the password simple and easy to remember, ...

AI Technical Summary

Problems solved by technology

From the perspective of cryptography, the above methods of establishing passwords will bring huge hidden dangers

People with ulterior motives can easily crack weaker passwords through exhaustive and dictionary attacks, obtain users' confidential information, and steal users' property and personal privacy

Therefore, it is best to use a number or name that is not easy to be cracked and guessed for the user password, and it is best not to have the same or similar passwords, so that the user password can be more effectively protected, but this brings another problem, that That is, users may often forget such complex and numerous passwords
