Abstract: IT revolution along with the industry revolution, gave birth to some modern technologies like internet, web technology, and cloud computing. Among these, cloud computing is the most advanced technology of sharing resources, which have deeply impacted our social life, work culture and privacy. Besides the positive aspects of these growing technologies, the negative impact must be given a second look. All industrial and social dealings are almost completely dependent on the cyber space which can be exploited easily because everything is open and there is lack of security in it. Hence the data exchanged through the communication channels, as well as the data residing in the remote storage spaces provided by the third party service providers, is under threat. Thus the cyber space which is the fifth domain according to modern view is to be protected after the other domains:land, sea, air and space, for developing and retaining the confidence and faith of its users. Different approaches have been proposed by several researchers for enhancing this security issue thorough various information hiding techniques. The latest technologies being used are cryptography, watermarking and steganography. Along with different cryptographic and watermarking techniques, a variety of steganographictechniques also havebeen used for secure transmission of data. Among which image steganography has been proved to have better features in terms of security, capacity, robustness and integrity than the other types. Thepaper focuses on these existing technologies andcompared them all on various aspects, to give an overview on the Security Zone in the web and its journey.

Keywords: Cryptography, Watermarking, Steganography, Information Security.
