A Novel Approach for Improving Security by Digital Signature and Image Steganography
Sarika Sharma, Vivek Kapoor · International Journal of Computer Applications · 2017
Information security is becoming more and more vital with the progress in the exchange of data.Protected communication in the network is a key necessity.Propose a novel technique to encrypt the image and embed the digital signature into the image.A digital signature is a procedure used to certify the authenticity and integrity of a message, software and digital documents.It is a also worn to give testimony of non-repudiation of communications.Steganography is an encryption technique that can be used along with cryptography as more-protected method rising to protect data.Images are the most admired cover objects used for steganography.In the province of digital images lots of different image file formats are present.Java technology proposed to authenticate the performance of the proposed model in circumstances of message length, key length, cipher text length and computational time for encryption and decryption.
