<p>Homomorphic encryption has been widely used to preserve the privacy of watermarking process on blockchain-driven watermarking services. It offers transparent and traceable encrypted watermarking without revealing sensitive data such as original images or watermark data to the public. Nevertheless, the existing works suffer from enormous memory storage and extensive computing power. This study proposed an approximation-based homomorphic encryption for resource-efficient encrypted watermarking without sacrificing watermarking quality. We demonstrated the efficiency of the Cheon-Kim-Kim-Son (CKKS) encrypted watermarking process using discrete cosine transform-singular value decomposition (DCT-SVD) embedding. The evaluation results showed that it could preserve the watermarking quality similar to non-encrypted watermark embedding, even after geometrical and filtering attacks. Compared to existing homomorphic encryption, such as Brakerski-Gentry-Vaikuntanathan (BFV) encryption, it has superior performance regarding resource utilization and watermarking quality preservation.</p>

Blockchain is a modern technology that has revolutionized the way society interacts and trades. It could be defined as a chain of blocks that stores information with digital signatures in a distributed and decentralized network. This technique was first adopted for the creation of digital cryptocurrencies, such as Bitcoin and Ethereum. However, research and industrial studies have recently focused on the opportunities that blockchain provides in various other application domains to take advantage of the main features of this technology, such as: decentralization, persistency, anonymity, and auditability. This paper reviews the use of blockchain in several interesting fields, namely: finance, healthcare, information systems, wireless networks, Internet of Things, smart grids, governmental services, and military/defense. In addition, our paper identifies the challenges to overcome, to guarantee better use of this technology.

Background: In the current advancement of communication, anyone can create digital content. Emerging digital marketplaces provides an environment to share digital data with customers who are interested in content, from other digital sources. Digital marketplaces provide a location for both providers and consumers to connect to meet the increased demand. All of this leads to challenges in content protection, copyright protection, contract creation and work trading. Objectives: To address these issues, this scheme suggests a blockchain based approach for managing digital rights to garment design works. This system uses the blockchain, digital copyright management techniques and off-chain computation for garment design work. The visibility of design effects, the secrecy of design details and compliance with applicable regulations are all considered. The data delivery is also assured with the help of the proof-of-delivery concept. Methods: The proposed system has three steps. They are (i) Creating digital copyright documents using key generation and verification of digital signature (ii) Smart contract creation (iii) Certificate generation for confirmed smart contracts. A Smart contract is defined as computerized transaction protocols that execute the terms of a contract. Findings: Smart contracts are created between the designer and customer using Ethereum which is a blockchain based software platform. The interplanetary file system is used to store digital documents. Ethereum blockchain is used to create the smart contract digitally. Ethereum smart contract provides unchangeable, transparent, tamper-proof logs, traceability and responsibility. Finally, E-certificate is generated by the designer for the confirmed contracts and it is uploaded into the IPFS. Novelty and applications: The trusted, decentralized and proof of delivery frameworks are included for digital design work with the key features of IPFS, blockchain and Ethereum smart contract. The proposed work is also compared with the existing works based on several criteria such as blockchain, IPFS, PoD, etc.
