A Novel Method of Hiding Transmission of Mobile Phone Images

Abstract

Network has become the most important channel for information transmission. However, insecurity of the network transmission makes information extremely leaky and intercepted. The security of network transmission has increasingly become the focus of attention. Information hiding technology provides a direction for solving this problem. What is called information hiding technology is to embed some important information into digital carriers (such as images, audios, videos, etc.) without damaging the original features of the digital carriers [1]. Mobile phones, as the advanced intelligent mobile terminal, photographing and sharing photos readily are its main functions. This paper mainly introduces a method to implement the hiding transmission of mobile phone images. Through the image format conversion, image Location Encryption-Least Significant Bits steganography [2] and mobile-side application development, we can achieve the realtime image hiding transmission function of mobile phone. Convert the image captured by mobile phone to bitmap for embedding secret images or other information expediently. Improvement in traditional LSB steganography: rearranging the secret image information, packing piecewise and taking Location Encryption-LSB steganography (LE-LSB) in specific pixels of the carrier image which can effectively increase the difficulty of cracking and improve the effect of steganography. The secret image information can be extracted and rearranged at the receiver and the secret image can be recovered. These steps are all implemented at the mobile terminal application. Through experiments, this method has better image hiding and transmission effect and protects secret image security. And it can complete this series of changes in real time in the mobile terminal, increasing the convenience which has a certain value of application.
