Multi-form instant information hiding communication method and system based on image medium

Abstract

The invention relates to a multi-form instant information hiding communication method and system based on an image medium. The system comprises a data conversion module, an encryption module, an information hiding module, a data transmission module, an information extraction module and an API interface. The data conversion module converts multi-form information (such as texts, voices or images) into binary data suitable for hiding; the encryption module is used for generating an information hiding secret key; the information hiding module is used for efficiently embedding the information after the encryption processing into a JPEG image. The data transmission module is responsible for carrier data safe transmission and cross-platform sharing functions. The information extraction module is characterized in that in an information hiding reverse process, the information hidden in the image can be seen only by inputting an encrypted password. An API provides the flexible interface to a user for calling system functions. According to the invention, the complete multi-form instant information hiding core algorithm and communication solution scheme based on the image medium are provided, and the method and the system provided by the invention have important theory and application values.

Description

technical field [0001] The invention belongs to the field of instant information security communication, and in particular relates to a multi-form instant information concealed communication method and system based on graphic media. Background technique [0002] With the widespread popularity of smart phones and the substantial increase in data transmission speed, today is the Internet era of self-media information. People like to use their mobile phones to take selfies or take pictures of life scenes, and share them through social networks (such as WeChat, QQ, Facebook, etc.) To my friends, leave a confession of my feelings at that time. It can be seen that pictures have become the most important source of information in self-media information. When people share pictures, they also share a kind of mood. Some moods involve personal privacy and are only willing to be open to designated friends, and some moods are only willing to be shared by themselves-save for later savorin...
