Research on digital copyright protection based on the hyperledger fabric blockchain network technology

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.

Comparison of Digital Copyright Protection on Over the Top (OTT) Streaming Content Media in Indonesia and the United States

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.

A novel method for copyright protection of digital videos using SWEA and ZPA technique

Digital copyright protection has become an effective way to prove the ownership and protect the multimedia contents from illegal use and unauthorized users. In order to prove the ownership of a video certain security program is embedded in a video and one of the ways of ensuring the ownership of a video is embedding the watermark in a video. In this paper, a new approach to digital video copyright protection, SWEA (Split watermark embedding algorithm) with Zero Padding Algorithm (ZPA) is proposed. With the help of this algorithm, it is hard to know the original pattern of watermark because of SWEA and minimizing the perceptual degradation of watermarked video because of ZPA. Here we are using ‘db1’ wavelet domain for embedding the watermark in the LL sub-band of the original identical frame (I-frame), based on the energy of high-frequency sub-band in an adaptive manner. SCD (Scene changed detection) is used to find out the identical frame (I-frame). The proposed algorithm has undergone various attacks, such as compression, uniform noise, Gaussian noise frame repetition and frame averaging attacks. The proposed algorithm, sustain all the above attacks and offers improved performance compared with the other methods from the literature.

Design and Implementation of Geometric Invariant Zero-Watermarking in Digital Copyright Protection

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.

Copyright and creation: repositioning the argument

Purpose – This paper highlights the challenges and key arguments for digital copyright protection legislation for creative industries. Design/methodology/approach – This briefing is prepared by independent academics who place the arguments in context based upon literature and market data. Findings – Many of the arguments used against copyright protection laws draw upon flawed analysis. Artistic creators should be treated fairly and their work should be afforded the same protection as other property. Practical implications – Digital legislation warrants review, but not for the frequently cited reasons of “stifling innovation” or “restriction” of others using the work. Rather, artists need better protection for their work and fairer treatment with regards their property rights. Originality/value – The paper provides context and practical insights into the data used to influence policy decision makers, providing a stronger case for legislative review.
