Abstract
Hacking became a big problem these days. Transmission of secure Data or communication through internet turns to be challenging due to security concerns. In order to forestall these security obstacles, we used Cryptography, Image Steganography. Over the centuries, there are numerous advancements in information security. Steganography and cryptography are the two emerging techniques for secure data transmission over years. Cryptography is the art of encrypting the text whereas Steganography is used to hide the text inside any multimedia element that appears to be nothing. Steganography makes the data secure as if any person views the file, he/she cannot sense that there is some secret message hide in that, human senses cannot detect or sense the data inside the multimedia element. In this paper, we proposed a system that uses both cryptography and steganography to ensure two levels of security to the data. The purpose of this paper is to develop new methodology using XOR operation for encrypting the data and embedding the encrypted data into the image pseudo randomly using user chosen key.
