Information camouflage method of mobile phone address book based on cloud platform

Abstract

The invention discloses a cloud platform-based mobile phone contact list information disguising method. Phone numbers in a contact list uploaded and issued between a cloud server and a mobile phone are all pseudo numbers. The pseudo numbers are decoded into real numbers by a number calculator according to an APP (Application) built-in key. The APP built-in key is combined by SIM (Subscriber Identity Module) card information, mobile phone numbers, mobile phone information, cloud specified codes and cloud random codes through an asymmetric algorithm. The encryption mode and algorithm of the cloud server can be changed at any time; after the encryption mode and algorithm are changed, the mobile phone terminal can synchronously and automatically update and download a new number calculator. The phone numbers stored or displayed by the server and the mobile phone are all pseudo numbers, so that only pseudo numbers can be seen by thieves even though the mobile phone is stolen, and the contact list information cannot be stolen easily; no high-grade encryption and authentication mode is required, so that low cost is realized; a number is dialed by a third party, so that the safety level is high and the customer resources can be effectively controlled; both the number calculator and the acquisition of the number calculation key are required to be authenticated for many times, so that the data safety is high.

Description

technical field [0001] The invention relates to a method for disguising information in a mobile phone address book based on a cloud platform. Background technique [0002] The enterprise address book has huge data value, so the encryption of the address book contact list is the ultimate basis for success or failure. The current mainstream corporate address books in the market are mainly encrypted in the way of confusion and diffusion. The methods adopted by different companies are basically the same. Most of the differences lie in the level of encryption. Some are encrypted with MD5, some are encrypted with a private algorithm, and some are encrypted with Military 128 or even 256 bit encrypted. [0003] At present, there is also a processing mechanism in the form of cloud plus end, that is: the mobile phone adopts high-strength encryption, and in the case of the loss of the mobile phone, through network detection (for example: the mobile phone has changed the card for some ...

[0005] Chinese patent application number 200810211442.5 discloses a method and system for disguising information, which can realize the disguising of information. However, the patent server switches according to the request of the client. Correspondence list, that is to say, the real information must be pre-stored in the server of the system, and the false information can be obtained by looking up the table according to the true-false information correspondence list. This information camouflage method based on the database true-false information correspondence list is very easy It is cracked, which brings huge hidden dangers to data security
