Moreover, it has been developed by paying special attention to good practices in the design of software. For using DPGraphJ, the problem to be solved needs to be modelled as an AND/OR graph. In the DPGraphJ package, we provide 5 academic case studies with detailed comments.

They can actually be enhanced through decentralization, particularly by using blockchain technology. Since transaction data on the blockchain are open and readable by all parties, a high level of user trust is achieved, enhancing transparency and interoperability across the network. The software we propose bridges the gap between the security of biometric information and the transparency of blockchain and decentralized technologies. Specifically, the software is a decentralized application (dApp), based on the Ethereum blockchain, which relies on a smart contract to manage its logic. The logic of the smart contract employs the fuzzy commitment scheme (FCS) to securely hash biometric templates, while always maintaining fault tolerance thanks to error correction codes (ECC). This mechanism ensures data integrity within a transparent, decentralized framework. The proposed dApp enhances biometric authentication by supporting both the enrollment and authentication processes. Its smart contract enables managing access control within this decentralized infrastructure. In practical applications, the proposed system can demonstrate its potential as a secure and decentralized alternative to traditional centralized systems.</div></div>","PeriodicalId":21905,"journal":{"name":"SoftwareX","volume":"28 ","pages":"Article 101932"},"PeriodicalIF":2.4,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142532528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
