| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this study, in order to search for a new digital content copyright management method that achieves both safety and convenience, we aim to improve the digital watermarking technology that embeds evidence information using content redundancy. In our previous study, we found three requirements for digital watermarking. The first is that to prevent watermark information of an image from being diverted to other images, this information must be generated based on the original image. The second is that after the original image is modified/edited, it should still be able to be used the same as the original image. The third is that multiple digital watermarks should be stored and managed without relying on trusted third parties. To meet these requirements, we proposed a digital-copyright-management system based on perceptual hashing and blockchain. However, because we used conventional perceptual hashing in that study, we could not draw sufficient conclusions about the first and second requirements. In this current study, to obtain a stable message digest, we propose a method of improving perceptual hashing based on machine learning and intermediate layer of convolutional neural network (CNN). These can be said to be next-generation technologies applicable to objective image quality evaluation methods and image retrieval systems. | |
