Image Steganography for Confidential Data Communication
S. Sravani, R. Raniith
Abstract
In the present-day communication system, one of the most important tasks is securing confidential data through a communication channel. Many adequate encryption and decryption algorithms have been developed. But due to growth in technology, these algorithms are prone to attack and there would be loss of information. This led to the development of the steganography method which hides the existence of confidential data. This paper mainly concentrates on steganography using the LSB algorithm. The process involves hiding a secret image in a cover image and then transferring it over the internet. This method can use multimedia such as text, images, audio files, and video files. Here, steganography is developed to hide a location of an area (ex in form of a map) in a cover image and transfer the image through the internet. The performance of this technique has been analyzed through MSE and PSNR values for its utility in security-based applications.
