Abstract

As the escalation of internet is one of the major traits of information technology, data hiding techniques has taken a significant role for the transmission of multimedia content. One of the essential properties of digital information is that it is in principle very simple to create and share out unlimited number of its duplicates. The fact that an unlimited number of perfect copies of text, image, audio and video records can be illegally created and distributed requires studying ways of embedding copyright information and serial numbers in image, audio and video data. Steganography brings a variety of very substantial technique how to conceal key information in an imperceptible and/or irremovable way in data like image, audio and video. Steganography is most important part of the fast emerging area of information hiding. In this work, we have deliberated steganography methods using LSB substitution for gray scale image also for colored images. Approaches for image steganography always focus on retaining the visual quality of an image while scrambling a secret message in it. The simulation results of our work indicates that this method achieves well especially when embedding secret data at higher LSB bit positions. There are few procedures that try to improve the quality of stego image by embedding secret data only in the channels of least importance. Our work also describes frequency domain techniques to achieve the enhancement in confidential and authenticated data storage and secured transmission. Performances of all these transform are compared according to application of data hiding technique. Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE) is used as a performance index to show the quality of steganographic image.
