چکیده
In this work, an algorithm and a tool for image authentication and restoration based on DCT coefficients, classic cryptography primitives, and blockchain are presented (Source code appears in https://github.com/capamir/image-authentication). The proposed scheme can verify the authenticity of an image that has been subjected to malicious alteration, localize the modified regions, and restore the original image. However, just the malicious areas (column-wise) will be reconstructed and substituted while the intact parts (columns) are left as are to save unnecessary reconstruction costs. The tool is currently provided as a prototype serving as a web interface that is able to detect the possible maliciously altered columns of the received image precisely and to store the generated hash on a blockchain structure in almost real time. Experimental results together with the analysis of the scheme presenting the performance and security of the approach are provided which enhances the usability and trustworthiness of the scheme in further developments.
