Abstract

In the era of information security, Steganography is a most secure method, used for concealing existence of secret data in any digital cover object such as image, audio, video and text files. In the last several decades broad research has been done on image steganography technique due to their easiness of data embedding and data extraction. Hide the existence of the embedded data in any digital object is the main objective of steganography. The main key factors of steganography are Undetectability, robustness and capacity of the concealed data that separate it from related techniques like cryptography and watermarking. Nowadays, video files are much more accepted because of large size and memory requirements. This paper intends to provide a survey on various video steganographic technique and covering its fundamental concepts.
