This paper presents the design and the verification of an efficient image protection method based on the QR code, which is a type of two-dimensional barcode widely used in various fields. For this purpose, we design a new image protection system consisting of a secure image generator and a secure image recognizer. One adds a new pre-processing block to the typical QR code generator and the other combines the existing QR code reader with a new post-processing block. The new architecture provides image de-identification. It is also flexible, allowing the use of text-based compression and encryption. We have implemented prototype applications for verifying the functions of the secure image generator and those of the secure image recognizer. As a result, it is shown that the proposed architecture can be used as a good solution for image privacy protection, especially in offline environments.

Unauthorized access of the data is one of the major threat for the real world digital data communication. Digital images are one of the most vital subset of the digital data. Several important and sensitive information is conveyed through digital images. Hence, digital image security is one of the foremost interest of the researchers. Cryptographic algorithms Biological sequences are often used to encrypt data due to their inherent features. DNA encryption is one of the widely used method used for data security which is based on the properties of the biological sequences. To protect the images from unwanted accesses, a new two stage method is proposed in this work. DNA Encryption and Polymerase Chain Reaction (PCR) Amplification is used to enhance the security. The proposed method is evaluated using different standard parameters that shows the efficiency of the algorithm.
