摘要：Steganography technique plays an important role in information hiding in any digital cover object. Security of information oninternet against unauthorized access has become a prime problem. Due to this, steganography technique becomes more popular.Steganography is the science which includes secret communication in an appropriate digital cover objects viz. audio, image, text and videofiles. The main objective of steganography technique is to hide the presence of the embedded information in carrier file and other objectivesare robustness, Un-detectability and capacity of the concealed data. Steganography is separate from other related techniques viz.watermarking and cryptography in term of robustness and Un-detectability of information. Watermarking is a technique that hidesinformation in digital image to protect intellectual properties and copyright, such as logo for proving ownership. Steganography andwatermarking are important techniques to conceal important data in cover object an undetectable and irremovable way. Both techniquesare the fast developing area of information hiding. This paper delivers a comparative study on digital images steganography andwatermarking techniques and significant research growths are also discussed.
