摘要: Data security and data integrity are the two challenging areas for research. So many research is progressing on field like internet security. The requirement of secure transmission important in our life. should be more when channel/network too noisy/fraudulent. Image one application that must securely transmitted over fraudulence network. Secure image required various fields medical/telemedicine, military etc. When it desired to send confidential an insecure bandwidth-constrained channel customary encrypt as well compress cover then embed confidential/important/secure into data.
