Compression of frequency domain based Stego-Image for swift transmission
Sudhanshu Garg, Farhan Khan
Network is a group of many computer systems connected together. Computer networks are of many types, which includes: local-area networks (LANs), wide-area networks (WANs) metropolitan area networks (MANS).Network security subsist of the policies adopted to prohibit and monitor unauthorized access, misuse, modification, or denial of network-accessible resources and a computer network. Security of network includes the authorization of access to data in a network, which is controlled by the network administrator. In this project, we send the data from sender to receiver securely by using steganography method. Steganography is used to hide the data inside the image. In existing system, the secret data which is embedded inside the cover image could make the resulting image very large in size, so it consumes more time for transmission. But in this proposed system, user can compress the data which is to be shared which will reduce the transmission time for sending the data from sender to receiver. Through this method of compression, the total time required for sending the data can be remarkably reduced. The main theme of this project is to transmit the data securely in the network. The user can hide the data in the image which he wants to share securely and also he can compress the data, so the files size will be reduced and this will increase the transmission speed of the data and hence can save a lot of time.
