A Novel Technique of Image Steganography for sensor information with socket TCP/IP connection
Ahmed Al-Baghdadi · 2015
Steganography is the art of hiding information in other information in order to hiding the fact that communication is taking place. It serves as a better way of securing message than cryptography which only conceals the content of the message not the existence of the message. There are different types of steganography but images are the most popular because of their frequency on the Internet. In this paper a novel way of image steganography is applied to embed information in colors of pixels and alpha (ARGB) using python language in four steps. First step include change all alpha that have 254 in byte to 255 in ARGB pixels. The second step include convert all information to bytes. Third step include select distributed pixels from image in suitable ratio depend on size of image in order to put information in it. Fourth step include put first byte of information instead of byte of blue color and make byte of alpha as 254. The result image is encrypted using base64 encoding techniques in order to send it using proposed TCP/IP socket between Python language and VB.NET language or any other way. The receiver represented by VB.NET program makes same steps in reverse arrangement for extract information. Python language is used in order use in raspberry pi platform to hide information of important sensors.
