Network information security input system and method based on independent encryption

Abstract

The invention relates to an independent encryption based network information safe input system. The system comprises a safe input method client end and a safe input method server end. The safe input method client end comprises an input method module and a content encryption and decryption module. The safe input method server end comprises a business show module, a business service module and a data access module, and a safe input method. The input method is not bound with a third-party application, so that the input method and the third-party application are separated but cooperate with each other. Information that the user needs to encrypt can be encrypted flexibly, namely, a certain passage of dialogue or key content can be encrypted; the user can encrypt and decrypt the information conveniently without through complicated operation; and information and a secret key are managed and transmitted through independent channels, thereby guaranteeing safe transmission of the information.

Description

technical field [0001] The invention relates to the technical field of network information security, in particular to a system and method for securely inputting network information based on independent encryption. Background technique [0002] With the popularity of smart phones and the rapid growth of mobile Internet users, the functions of mobile phones are becoming more diversified. The functions of mobile devices are becoming more and more powerful. As the most frequently used mobile phone software, input methods are applied to more and more functions. Relevant information shows that text input has become a daily routine for mobile phone users when writing text messages, writing emails, sending Weibo and most other applications. At present, there are many types of input methods, and the most widely used ones are Sogou input method, Tencent input method, Google input method, Ziguang input method, Baidu input method, etc., but they all focus on how users can quickly input...

Problems solved by technology

What's more serious is that when you send sensitive information such as card number and password to your friends, once it is stolen, it will directly cause economic property loss

At present, due to the popularization of mobile devices and the diversity of existing application software, the attacks of malicious software such as program loopholes and Trojan horses directly cause user information to be stolen, bringing great security risks

The current solutions are mainly divided into two types: one is the method of providing a safe input method by the application itself, but there are problems such as tight coupling with the application, difficulty in development, high development cost, and limited application range; Network authentication and encryption measures, such as VPN, OpenID, etc., but these heavier enterprise-level solutions still have performance and user experience problems for current mobile devices
