Research ArticleOpen accessPhrase in the titleBlockchain-Enabled Privacy-Preserving Access Control for Electronic Health Records Using Smart ContractsG. Bhanu Prasad, M. Venkateswara RaoElectronic medical records are crucial for providing high-quality healthcare, but they also raise serious privacy and security issues. Traditional centralised storage systems are vulnerable to manipulation, hacking, and illegal access. This study suggests a smart contract-based blockchain architecture that provides decentralised, unaltered, and privacy-preserving access control for EMRs. The model integrates cryptographic techniques like AES-256 encryption and SHA-256 hashing for … …Journal of Computer Science, Vol. 22, Issue 6 · 22 Jun 2026 · 1,306 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Federative Access Control in a Cloud Environment with a Publish/Subscribe ProtocolAbdelali Saidi, Khalid Aissaoui, Abdessamad MektoubiCloudcomputing is a new concept that has interesting advantages; high computingperformances provided as needed, much lower cost than in-house infrastructures,and better reliability and scalability. However, with some drawbacks that areimpeding its adoption, security is so far the most alarming concern forcompanies or organizations. Access control policies, for example, are the mostchallenging issue that has been tackled these last years; to … …Journal of Computer Science, Vol. 18, Issue 10 · 5 Oct 2022 · 6,012 accessesView PDFCite

Research ArticleOpen accessPhrase in the titleHIERARCHICAL ACCESS CONTROL IN DYNAMIC PEER GROUPS USING SYMMETRIC POLYNOMIAL AND TREE BASED GROUP ELLIPTIC CURVE DIFFIE HELLMAN SCHEMEKumar Krishnan, Sumathy Vembu, Nafeesa Begum JeddyHierarchical Access Control in group communication is an active area of research which is difficult to achieve it. Its primary objective is to allow users of a higher authority group to access information or resource held by lower group users and preventing the lower group users to access information held by higher class users. Large collection of collaborative applications in … …Journal of Computer Science, Vol. 10, Issue 9 · 15 Apr 2014 · 6,999 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleTHE ACCESS CONTROL SYSTEM BASED ON LINEAR DISCRIMINANT ANALYSISWidodo BudihartoFace recognition represents an important computer vision domain that has been researched in the last decades. The objective of this research is to develop an Access Control System based on Face Recognition using Linear Discriminant Analysis (LDA) method. The analysis is done by making an application of face recognition using LDA for extracting features of the face and the output … …Journal of Computer Science, Vol. 10, Issue 3 · 29 Nov 2013 · 6,936 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleTemporal, Delegable and Cheap Update Access Control to Published XML DocumentsWaleed Halboob, Ali Mamat, Ramlan Mahmod, Muhammad Khurram KhanProviding access control for published XML documents on the Web is an important topic. It involves the use of cryptographic techniques, addressing different requirements and, as a result, facing several challenges. Existing solutions still have some weaknesses such as system update cost, number of required secret encryption/decryption keys, size of encrypted document and supporting temporal and delegable access. This study … …Journal of Computer Science, Vol. 9, Issue 4 · 8 May 2013 · 6,532 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleAn Optimal Rate Adjustment Algorithm for Medium Access Control Protocol in 802.11 Multi Hop Ad Hoc NetworksT. Ravichandran, K. SaravananProblem statement: Medium Access Control (MAC) protocol plays an important role in providing a fair and efficient allocation of limited bandwidth in wireless LANs. In IEEE 802.11 standard protocol, data rate selection is not specified. Rate control is the process of switching data rates dynamically based on channel conditions, with the target of selecting the rate that will provide the … …Journal of Computer Science, Vol. 8, Issue 7 · 9 Jun 2012 · 7,023 accessesView PDFCite
Research ArticleOpen accessPhrase in the titlePurpose-based Versus Flow-Based Access Control for PrivacySabah Al-Fedaghi, Bashayer Al-Babtain, Maha Al-FahadProblem statement: Data protection legislation requires handling of Personal Identifiable Information (PII) in special ways to guarantee privacy. Specifically, the notion of handling purpose plays an important role in current access control mechanisms that allow only actions corresponding to intended purposes. A problem that arises in this context is how to ensure that PII is used solely for the intended … …Journal of Computer Science, Vol. 8, Issue 4 · 8 Feb 2012 · 6,819 accessesView PDFCite
