Blockchain-Based Smart Propertization of Digital Content for Intellectual Rights Protection

Several platform companies have been successful in competing with digital piracy by producing consumer-friendly services. Nowadays, however, the digital content service market has become more monopolized than ever, which forms barriers to the entry of new platform companies. The platform monopoly would cause considerable problems both to content providers and consumers as it limits the choice of consumers. To remove the platform monopoly in digital content markets, we propose a public blockchain-based digital content service method. The proposed method encrypts the digital content to a self-decryptable form, which we call Smart Propertized Digital Content (SPDC), and utilizes the decentralization and traceability of the public blockchain to provide a non-monopolistic ecosystem for the management and distribution of the SPDC license. The proposed method can be more beneficial both to content creators and users than the current winner-takes-all platform model. For instance, users can download SPDC once and play many times without requesting the decryption key, and SPDC owners can make SPDC licenses to be time-limited, device-limited, resellable, or terminated without resorting to help from other intermediaries. We conducted the threat analysis on the proposed method by examining possible attacks in various scenarios. Based on threat analysis, we conclude that the proposed method can provide a new type of digital content service ecosystem that can be operated in a completely decentralized way and neutrally beneficial to all participants.

“…The hash value for the license is included to ensure license data integrity. The hash value for the previous block, creation time, user authentication information, and content provider information are provided as headers in the SB, and the SB body stores encrypted content and license information [26]. This solves the storage limitations and personal privacy problems because the SB is solely owned by the consumer.…”

Blockchain is attracting attention as a new solution for problems such as illegal copying, profit distribution, and forgery and falsification in the digital content trading environment, which has become an essential asset in the information age. However, one problem is that it is difficult to propagate digital content to the blockchain network because of a limited capacity to upload to the blockchain. The integrity and transparency of blockchain are also considered as weak points in terms of privacy. In this paper, we propose a new blockchain system, the secret block-based blockchain (SBBC), to address the problems with the blockchain system in the digital content trading environment. SBBC is composed of off-chain and on-chain network components. Off-chain is the part that allows trading digital content through the authentication phase. The digital content that is traded has a digital fingerprint inserted, so if an illegal leak occurs, the destination can be tracked. In addition, the content is encrypted and traded, and only the rightful user can use the digital content, thus ensuring income for the legitimate content author. Next, the on-chain network is licensed to use digital content, and a verification process using a consensus algorithm is performed. The licensed consumer creates a secret block of their transaction and records it only on their ledger. In a private part, secret block creation ensures privacy and solves the network overload that can occur when uploading digital content to the blockchain. Finally, through the verification and agreement of all blockchain participants, a public block is created and recorded in the ledger to finalize the transaction. Consequently, we propose the SBBC system suitable for digital content trading environments and a safe and reliable system through a consensus algorithm in such environments.

“…Existing techniques for data rights lack transparency, decentralization, and trust. In response to above mentioned problems, Zhang and Zhao in [9] proposed blockchain-based decentralized solution. Information regarding the use of digital content, such as transaction and license information is transparent to everyone.…”

A Secure Data Sharing Platform Using Blockchain and Interplanetary File System

In a research community, data sharing is an essential step to gain maximum knowledge from the prior work. Existing data sharing platforms depend on trusted third party (TTP). Due to the involvement of TTP, such systems lack trust, transparency, security, and immutability. To overcome these issues, this paper proposed a blockchain-based secure data sharing platform by leveraging the benefits of interplanetary file system (IPFS). A meta data is uploaded to IPFS server by owner and then divided into n secret shares. The proposed scheme achieves security and access control by executing the access roles written in smart contract by owner. Users are first authenticated through RSA signatures and then submit the requested amount as a price of digital content. After the successful delivery of data, the user is encouraged to register the reviews about data. These reviews are validated through Watson analyzer to filter out the fake reviews. The customers registering valid reviews are given incentives. In this way, maximum reviews are submitted against every file. In this scenario, decentralized storage, Ethereum blockchain, encryption, and incentive mechanism are combined. To implement the proposed scenario, smart contracts are written in solidity and deployed on local Ethereum test network. The proposed scheme achieves transparency, security, access control, authenticity of owner, and quality of data. In simulation results, an analysis is performed on gas consumption and actual cost required in terms of USD, so that a good price estimate can be done while deploying the implemented scenario in real set-up. Moreover, computational time for different encryption schemes are plotted to represent the performance of implemented scheme, which is shamir secret sharing (SSS). Results show that SSS shows the least computational time as compared to advanced encryption standard (AES) 128 and 256.
