A Comparative Study on Pattern Based Image Steganography

Abstract:
The speedy growth of the Internet and digitized contented made text/image delivery simpler. The capability to protect and secure information is dynamic to the growth of electronic trade and to the growth of the Internet itself. A safe data transmission over computer networks can be realized concluded steganography and cryptography. Steganography is a technique used to transmit a secret message from a source to a receiver in a way such that a probable intruder does not suspicious the being on the message. In steganography different-different carrier files can be used, but the most popular is digital images because they are used a proportion now a day on the internet. Steganography helps in the communication of secured data in numerous carries like images, videos and audio. In image steganography the information is hidden entirely in images. A comparative study on pattern based image steganography, one of the drawbacks of most of the current steganography methods is that it changes the bits used for storing color information. A comparative with different three methods of steganography, pixel pattern, 3D pattern, Dynamic pattern. [1,10]In this Paper, means to give an overview of image steganography, its uses and techniques. It also endeavors to classify the requirements of a good steganography algorithm using pattern based and briefly reflects on which steganography techniques are more suitable for this pattern based steganography.
