Abstract: Now a day everywhere Digital formation is involved. all people are use to technology in daily life but the excess use of technology safety is also more important. Quick response code is the process that high quality features such as stored high capacity information in small coded from and embed the secret information. The cryptography technique is used for hiding secret message, the process at the sender side to encode the original message in to any coded from and at receiver side the decoded the original message. Hiding original message is based on bit technique so it is chance to modification attack.if attacker change any bit such as adding a new bit or change the bit then it is some problem arise to recover the original message. In this paper, we propose the a scheme based on Cyclic Redundancy Check and list the decoding to overcome this problem we also conduct our solution by analyzing the complexity, security, experiment.
