Satpute Pune University, Flora Institute of Technology, Khopi, Pune yashasrisatpute@gmail.com Prof. Bharat A. Tidke Pune University, Flora Institute of Technology, Khopi, Pune batidke@gmail.com Abstract Data hiding is mainly used to hide the secret data into a cover data like a video file, an audio file, an image, etc. It is popularly used in medical and military applications. Nowadays reversible data hiding is the latest research area in the field of secret data hiding techniques. This paper covers many hiding and compression techniques like vector quantization (VQ), side match vector quantization (SMVQ), histogram shifting technique, locally adaptive data compression technique, and many more. But the topic of our interest is side match vector quantization. 1. Introduction Data hiding involves embedding significant data into various forms of digital media such as texts, audio, video, images, etc. secretly. It is a method of secret data transmission in the internet. Data hiding has been widely used in secret communication, copyright protection, and fingerprinting. The purpose of data hiding techniques is different from that of traditional cryptography or watermarking techniques. Cryptography encrypts the messages into a meaningless data while watermarking is used to protect the copyright. There are mainly two types of data hiding techniques: irreversible and reversible data hiding techniques. In irreversible data hiding techniques, only the secret message is recovered, while in reversible data hiding technique, both the secret message and the cover media is recovered completely. There are many data hiding techniques for the compressed data, which can be applied to various compression techniques of images like JPEG, JPEG2000 and
