Abstract
Steganography is an art of hiding important information in another information which is not important. This branch of science provides a large scope of information security in terms of data transmission. When the data is being transmitted over the internet, there is always a possibility that it might get stolen, as digital data is hackable. Cryptography has proven very helpful in this context of providing high security. With the help of steganography, security level can be increased. The main concern in steganography is the capacity of a cover data to hide the secret data. The size of secret message image must be smaller than the size of cover image, as higher amount of secret data to be hidden can affect the quality of cover data. In this paper, an algorithm has been proposed to increase the capacity of the cover data to its maximum extent to hide the secret information. The algorithm hides the secret information which has the same size as the cover information. The algorithm has been implemented on images and contains the block mapping of both images (Cover and secret) using histogram equalization, and finding the best suitable area to embed the message
