Enhancement In Data Security for Generation of Novel Encrypted Code Using Cryptography for Multiple Level Data Security

Abstract

In today's scenario, where everything is based, there is a huge demand for data security. A large number of cryptographic techniques are available to handle this problem. EPR is a collection of several private information related to a patient which needs data authenticity, data security as well as safe and secured transmission. The proposed methodology used both cryptography and image processing techniques to build a new type of encrypted information code in image format which can be transmitted and used like bar code, QR code but even more secure. The success rate of recovery of data is 100% for both short and long messages. The information can also be retrieved at the receiver side exactly same without any loss of information. Use AES algorithm consequently, with three keys and followed by some image processing techniques like complement, flip make the proposed algorithm more unbreakable. In this analysis a complete Graphical User Interface (GUI) has been developed for both encoder transmitter and decoder- receiver section. To increase data security, data can first be compressed using compression techniques and then encryption techniques can be applied. This technique increases the security and reduces the speed.
