Abstract

The invention provides a mobile phone address book management method based on image steganalysis, comprising a saving step and an extraction step. The saving step comprises the sub steps as follows: getting a carrier picture as a hidden storage space on a mobile phone; setting an extraction password of the hidden storage space; acquiring contact information needing to the saved to the hidden storage space; and using an image steganography algorithm to embed the contact information needing to the saved to the hidden storage space into the carrier picture. The extraction step comprises the sub steps as follows: acquiring the extraction password of the hidden storage space through mobile phone input; loading the carrier picture, and using the image steganography algorithm to extract the contact information embedded into the carrier picture; and displaying the extracted contact information via a mobile phone interface. According to the invention, mobile phone address book information is divided into general information and important information, and the image steganography technology is used. Compared with other mobile phone address book management methods, the mobile phone address book management method of the invention is of higher security and practicability.

Description

[0001] technical field [0002] The invention relates to the technical field of mobile phones, in particular to a method for managing mobile phone address books based on image steganography. Background technique [0003] With the increasing maturity of mobile communication technology and the significant reduction of mobile communication costs, mobile phones have become a very popular electronic consumer product. The mobile phone address book is a collection used to record the name, address and contact information of the communication target object. As communication becomes more and more frequent, the amount of data in the address book is also increasing. How to safely save the address book has become an urgent need. [0004] According to the storage location of the address book, it can be divided into two types: local storage and remote storage. Local storage, that is, the user directly saves the address book in the local communication terminal. Remote storage means that ...
