Signature Image Hiding in Color Image using Steganography and Cryptography based on Digital Signature Concepts

摘要: Data Transmission in network security is one of the most vital issues today's communication world. The outcome suggested method outlined over here. Enhanced can be achieved by this method. vigorous growth field information has made transmission much easier. But type advancement opened up many possibilities being snooped. So, day-by-day maintaining becoming an inseparable part computing and communication. In paper, authors have explored techniques that blend cryptography & steganography together. steganography, kept hidden behind a cover image. approaches for hiding using both proposed keeping mind two considerations - size encrypted object degree security. Here, signature image into private key sender receiver, which extracts from stego public key. This approach used message authentication, integrity non-repudiation purpose.
