Abstract

In this age of growing and developing information and technology, data security, integrity and confidentiality are essential aspects related to shared data over some network or medium. Many techniques over the years have been developed for securing the messages from attack or theft or breach of very sensible and essential data when shared over a network. The security threats to data have been ascending, so are the data hiding or securing techniques. This is where Information Security has a role to play. Development of techniques and methods that prevents the essential and secret data being stolen and thus providing security to the data. This paper discusses the significance of Information Security, its evolution since its infant stage and study about various subdomains of the same. This paper also shows a comparative study of various Information Security Techniques, their pros and cons and the applications in various domains. This paper analyses various Information Security methods or techniques based on their various characteristics and effectiveness on securing the data from any adversaries. This includes a study of some benchmark techniques and their subsidiaries along with it. The techniques under focus for analyzing were Watermarking, Digital Signatures, Fingerprinting, Cryptography, Steganography and latest being CryptoSteganography Information Security Technique. The characteristics focused were security-related properties, data or message-related properties, their objectives, drawbacks, applications and algorithms.
