Image steganography approach using spatial and transform domain technique

Abstract

Cryptography is often used to keep information confidential by making it illegible. However, incomprehensible information may raise suspicions of the adversary and may lead him to sabotage this style of communication. Therefore, steganography has a place in the arena of information security. Steganography refers to the technique of hiding information in digital media to hide the existence of information. Data caching is the art of hiding data for colorful purposes similar as; to maintain private data, secure non-public data and so on. Securely exchange the data over the internet network is veritably important issue. So, to transfer the data securely to the destination, there are numerous approaches like cryptography and steganography. In this design we propose a LSB & DCT grounded steganographic system for hiding the data by applying Least Significant Bit (LSB) algorithm for bedding the data into the images which is enforced through the HTML, CSS, JavaScript.
