Different Aspects and Reviews on Steganography for Data Hiding
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 6
Abstract
Security of confidential information has always been a major issue from the past times to the present time. It has always been the interested topic for researchers to develop secure techniques to send data without revealing it to anyone other than the receiver. Therefore from time to time researchers have developed many techniques.to fulfill secure transfer of data and steganography is one of them. Steganography is the art and science of communicating in a way which hides the existence of the communication. Important information is firstly hidden in a host data, such as digital image, text, video or audio, etc, and then transmitted secretly to the receiver The main aim in steganography is to hide the very existence of the message in the cover medium. Steganography and cryptography are counter parts in digital security. The obvious advantage of steganography over cryptography is that messages do not attract attention to themselves, to messengers, or to recipients. Also, the last decade has seen an exponential growth in the use of multimedia data over the Internet.These include Digital Images, Audio and Video files. This rise of digital content on the internet has further accelerated the research effort devoted to steganography.In the current work we are going to present the different aspects and reviews on stegnography , that has been completed and studied by different authors.
