Digital copyright protection is a bottleneck in the cross-media industry currently. In this paper, image normalization technique is used to map image into a geometric invariant space. Then, important area is extracted from the normalized image. At last, important area’s low-frequency DCT coefficients and watermark image are used to construct copyright information. Simulation results show that, without changing original image data, the proposed scheme is robust to geometric attacks and some conventional signal processing attacks. Hence it provides an effective solution for high reliability copyright protection.

In this paper, Arnold transform and Singular Value Decomposition(SVD) are combined to be introduced into the research of wavelet domain digital watermarking algorithm.During experiment,we embed the watermark through modifying the singular value of low-frequency domain of host image with the scrambled watermark information.The simulation experiments show that the algorithm realizes the embedding and extraction of watermark smoothly.There is no visual difference between watermarked image and original host image can be found by naked eye,that means the invisibility of the algorithm is well;the watermark still can be extracted after several kinds of algorithm and geometric attacks,that means the robustness of the algorithm is acceptable.The research has a certain value in the digital copyright protection and security printing.

In the rapid technological development, physical boundaries have begun to disappear. The internet has created a ‘free culture’. In addition, the era is challenging the copyright concept along with the emergence of ‘digital copyright’. It has become the main commodity of Over-the-Top services providing means of communication and entertainment through the internet. Content streaming service like Netflix uses films, as well as other cinematographic works, as its main commodities. OTT Streaming media helps to protect copyright holders' rights that previously have been violated by illegal streaming sites on the internet. Unfortunately, it also raises a new question: how digital copyright-objects can be protected in this kind of service. Without physical form, copyright object can be distributed easily on the internet, and it may lead to right violations. To answer this problem, the authors aim to describe the digital copyright protection on OTT Streaming Content Media in Indonesia and compare them to the 1998 Digital Millennium Copyright Act (DMCA) of the United States of America using a descriptive-analytical approach. This study employed a normative juridical approach with secondary data. The results of this study indicate that digital copyright protection in Indonesia is still centered on conventional copyright objects, and a sui generis law is needed to provide better protection for digital copyright objects.

With the recent development in network technology over a few years, digital works can be easily published online. One of the main issues in the field of digital technology is the infringement of digital works, which can seriously damage the data owners’ rights and affects the enthusiasm of the owners to create original work. Thus, more attention is required for the protection of digital copyright as it has a great impact on the development of society. Many digital copyright protection techniques were developed in the past, but still, there are many loopholes in the protection systems to be covered. The protection means are still relatively weak, timeliness is poor, infringement is frequent, a right determination is cumbersome, and the results are not ideal. Aiming at the mentioned problems, this paper proposes a protection technique, which can realize the automatic management of the complete digital rights life cycle on the blockchain using fabric's smart contract technology. The proposed system is based on blockchain technology, which leverages the distributed, tamper-proof and traceable characteristics of blockchain. The system uses smart contracts to manage the full life cycle of digital copyright. The test results show that the proposed system provides effective protection of the digital copyright system and can efficiently confirm the rights of digital copyright.
