SECURING THE DATA USING VIDEO STEGANOGRAPHY
Main Article Content
Abstract
Steganography is a process of hiding important message or data inside other data to protect the important message from unauthorized users. Messages and converted data may be any type of data such as text, audio, image, and video. The main aim of steganography is to mask the hidden message and to prevent the hidden messages from being detected from unauthorized access. In this project we proposed a frequency domain steganography technique for hiding large amount of data with high security a good invisibility and no loss of secret message. The basic idea to hide information in the frequency domain is to alter the magnitude of the entire DCT coefficient of cover image. The 2-D DCT converts the image block from spatial domain to frequency domain.The 2D-DCT ofthe video is taken and the secret message is embedded.The PSNR value is calculated to evaluate the quality ofthe video after the data hiding. The simulation resultsshows that the proposed algorithm is the best suited forsteganography.
