Embodiment Construction

[0049] At present, clients such as text messages are not encrypted during transmission, and are easily intercepted or leaked. Clients such as WeChat and QQ are encrypted at the bottom of the transmission process, but they are displayed on the client. When displaying, it is the plain text displayed directly. If the mobile phone is lost, or other people share the mobile phone, or the server account is stolen by others, the past sensitive chat records will still be leaked, causing huge losses to users.

[0050] In order to solve the above problems, the embodiment of the present invention provides an information encryption method that directly encrypts the communication content on the mobile terminal. The user can directly encrypt the plaintext that needs to be encrypted before sending, and then send it after encryption. What the other party receives is ciphertext, and the other party can only decrypt it through the key agreed by both parties. In this way, even if other people obt...

Abstract

The invention provides an information encryption method and a mobile terminal and relates to the field of mobile communication. The security problem of leaking information of a user through a terminal is solved. The method includes the steps that an encryption instruction is obtained; according to the encryption instruction, plaintext inside an input box is encrypted to obtain ciphertext; the ciphertext is used for replacing the plaintext to be displayed. According to the technical scheme, the information encryption method and the mobile terminal are suitable for communication software, and input information in the communication software is encrypted.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an information encryption method and a terminal during a real-time session. Background technique [0002] With the rapid development of the mobile Internet and the popularity of smartphones, social software based on smartphones and instant messaging software cannot greatly change the way people communicate. During the communication process, it is often necessary to send some sensitive private information, such as bank card numbers, passwords, or important business secrets that can only be known by both parties. If the information can be encrypted and sent during the sending process, it will provide users with more assured security. At present, clients such as text messages are not encrypted during transmission, and are easily intercepted or leaked. Clients such as WeChat and QQ are encrypted at the bottom of the transmission process, but they are displayed on the client. Whe...
