A cross-platform information input and output protection system

Abstract

The invention discloses a cross-platform information input and output protection system, comprising: 1. a cross-platform input method assistant software, which can be installed on a plurality of operating systems, is used for setting encryption / decryption keys and managing key information, encrypting data and decrypting data, 2. a cloud key cent, including key generation, key distribution and keymanagement modules, can synchronize data between the local key database and the remote key database system, 3. an encryption algorithm library, which can use or combine multiple encryption algorithms,4. a decryption algorithm library, which can automatically match and combine the decryption algorithm according to the parameters of the key, 5. an encryption module which can quickly encrypt the information data input into the buff area by the system of the device through calling the encryption function by the cross-platform input method assistant software, and 6. a decryption module, which cancall the decryption function to decrypt the information data in the system output buffer of the device quickly. The invention can effectively protect various kinds of privacy information of people innetwork communication, and has strong practicability.

Description

Technical field [0001] The invention relates to the field of information technology, in particular to a cross-platform information input and output protection system. Background technique [0002] With the rapid development of computer information technology and the continuous improvement of people's awareness of privacy protection in the new era, people's demands for privacy protection in various scenes of daily life are becoming stronger. There are many privacy leakage problems in the use of the current Internet and smart devices: when people’s mobile phones or computers are poisoned, personal property information, chat information, photos, videos, etc. in the device will be illegally obtained; without data encryption for communication and transmission , Personal privacy will be monitored by others; personal information will be leaked when the device is used on an insecure network; when the computer or mobile phone is lost, all kinds of information data will be peeped by others...

AI Technical Summary

Problems solved by technology

There are many privacy leakage problems in the use of the Internet and smart devices today: when people's mobile phones or computers are poisoned, personal property information, chat information, photos, videos, etc. in the devices will be illegally obtained; , personal privacy will be monitored by others; using equipment on an unsafe network, personal information will be leaked; when the computer or mobile phone is lost, all kinds of information and data will be peeped by others, resulting in privacy leakage

However, the existing network operation service providers and various smart device privacy protection methods cannot fully guarantee the security of user information and data.
