Secure information transmission over the web is one of the critical parts of the information correspondence as the information is a critical resource for correspondence over the web. Accordingly, information security plays a standout amongst the most noteworthy parts for conveyance and transmission of data over unreliable organize. Information security includes insurance of information from different kinds of assaults like interruption or unapproved access of information which are done over the web. Distinctive procedures like cryptography, steganography, watermarking or fingerprinting are utilized to add security to the information exchanged over the web. While cryptography utilizes encryption of information for the reason of security, information concealing methods are utilized for steganography, watermarking and fingerprinting. Steganography makes utilization of information pressure and also cryptography to give a superior security to the information. It can be utilized for various sorts of information like content, picture, sound or video. Information pressure procedures like DCT and DWT are utilized as various changes for giving a higher security and protection of the data.
