<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>
Archives play a vital function concerning the dynamics of people and nations as an instrument to treasure information in diverse domains of politics, society, economics, culture, science, and technology. The acceleration of digital transformation triggers the implementation of a smart government that supports better public services. The smart government encourages a national archival system to facilitate archive producers and users. The four electronic-based government system (SPBE) factors in the archival sector and open archival information system (OAIS) as a data preservation standard are the benchmarks in developing this study's national archival platform system. An improved service computing system engineering (SCSE) framework adapted to the microservice architecture is used to aid the design of the national archival platform system. The proposed design met the four-factor service design validation of coupling, cohesion, complexity, and reusability. Also, the prototype suggests what resources are needed to put the design into action by passing the performance test of availability measurement.
A rise in the number of digital ecosystem users, as well as an increase in cyberthreats, has occurred in recent years. Risk of security breaches puts important data at risk for the public. With its high-level encryption security features, blockchain technology keeps data safe from unauthorized access. The study's goal is to find out if the blockchain framework can withstand the modern cyberthreats that exist inside the digital ecosystem today. It is critical that consumers are informed of the potential dangers of their online activities. These cyberthreats have been identified in the digital environment according to the research. An additional focus of the research is on identifying and resolving any security vulnerabilities with blockchain technology. The problem statement of the study, which is cyberthreat, is discussed in the introduction. It is also important to understand how blockchain operates and evaluate its security. Aim and purpose of the research are outlined in the introduction. The literature review discusses the study identified areas, gaps toward the issue, and the strategy to dealing with the gaps. The study's research approach makes use of a survey questionnaire and a random sample method to conduct descriptive research. Approximately 100 people are expected to participate in the survey. The analysis will be based on the figure itself where we evaluate based on how it shows. As a consequence, this finishes the study and provides further recommendations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
