Privacy of Patient Information Implementation and Security Analysis of a Secure Three Tier Patient Information System based on QR Code

In the era of technology data security and information sharing is always a hot topic to talk on. There are lot of methods that are being used in security for secret information sharing such as cryptography, steganography, watermarking etc. another technology that is being used by people is QR code based information sharing but this technology is not enough to provide privacy in information sharing. Therefore, there is need of a better security algorithm which can be used for secure communication and have better efficiency and accuracy than others. In this paper author proposed a QR code based cryptographic technique which can be applied for security patient information.
