Data Hiding in Video Streaming by Code Word Substitution

Data hiding techniques can be used to embed a secret message and secret image into a video bit stream for copyright protection, access control and transaction tracking. They are some data hiding techniques to assess the quality of video in the absence of the original reference. To avoid the drawback of existing system such as lossless compression, gray scale mapping and noisy images forces higher bit plane when distortion are easily visible.Data hiding is also used for concealment in applications of video transmission, gray scale mapping and noisy image. Edge quality information and number of bits of a block are hidden in the bit streams processed in an encrypted format to maintain security and privacy. DOI: 10.17762/ijritcc2321-8169.15035

A Review on Audio � Video Stegnography

Security is most important issue in digital communication. Data security means protective digital privacy measures that are applied to prevent unauthorized access to computers, huge databases and online data it is also protects data from corruption. Security is most important issue in digital communication. Cryptography and steganography are two popular methods available to provide security. Steganography focuses on hiding information in such a way that the message is undetectable for outsiders and only appears to the sender and intended recipient. It is useful tool that allows covert transmission of information over and over communications channel. Steganography is a technique which is used to hide the message and prevent the detection of hidden message. Various modern techniques of steganography are: a) Video Steganography b)Audio Steganography Audio Video steganography is a modern steganography of hiding information in a way that the unwanted people may not access the information

An Efficient Approach to Secure Versatile Data File in Video using Forbidden Zone Data Hiding Technique

Video Steganography is a technique in which we can hide all types of files with any extension into a carrying Video file. In this dissertation, we are using two main terminology that is host file and carrier file where host file is a hidden file (any kind of file like text file, image file, and audio/video file) and carrier file must be a video file. The main motivation of this dissertation is to secure transferring of data by using steganography and cryptography technique. It is concerned with embedding information in an innocuous cover media in a secure and robust manner. In this dissertation we are using Forbidden Zone Data Hiding technique where no alteration is required in host signal range during data hiding process.To securely transferring the data file, we use video data hiding and making use of correction capacity of repeat accumulate code with superiority of forbidden zone data hiding. Using this approach we can also hide and transfer the large video file whose size is larger than cover file in secure manner. The main advantage of using video file in hiding information is the added security against of the third party or unintended receiver due to the relative complexity of video compared to image and audio file
