Problems solved by technology

However, using a fixed encryption algorithm for encryption will bring some problems. For example, when using a more complex (such as high encryption strength) encryption algorithm, the encryption or decryption process will reduce the performance of the mobile terminal. Simple (such as low encryption strength) encryption algorithm, because the encryption degree of the encryption algorithm is not enough, the information security will be relatively low

Abstract

The embodiment of the invention discloses an information encryption method and apparatus, and a terminal. The information encryption method disclosed by the embodiment of the invention comprises the following steps: obtaining current geographical location information of the terminal and user behavior information of a user, then obtaining a necessary target encryption algorithm according to the geographical location information and the user behavior information, and when the target encryption algorithm is different from the encryption algorithm of the current encryption algorithm, encrypting to-be-encrypted information according to the target encryption algorithm. The scheme can improve the security of information and the performance of the terminal.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to an information encryption method, device and terminal. Background technique [0002] With the rapid development of mobile terminals, they have become an indispensable part of people's daily life. However, the information security problems of mobile terminals such as smart phones and tablet computers are gradually revealed. For example, mobile phone passwords are stolen, personal privacy data is leaked, relevant deposits in electronic banking are stolen after the mobile phone is lost, etc. [0003] In order to improve the information security of the mobile terminal, information is generally encrypted, and specifically a fixed encryption algorithm is used to encrypt information. However, using a fixed encryption algorithm for encryption will bring some problems. For example, when using a more complex (such as high encryption strength) encryption algorithm, the encryptio...
