Research ArticleOpen accessIn the keywordsSEAchain: A Privacy-Preserving Dual-Credential Model on BlockchainS. Balachander, A. MuruganAll facets of daily life are now impacted by transaction data. The complex and heterogeneous network created by millions of users, devices, online services, and applications makes digital identity management more difficult. Users can maintain control over their personal information via distributed identity, a potentially useful model for resolving identity issues. Nevertheless, current state-of-the-art techniques are inappropriate because of persistent … …Journal of Computer Science, Vol. 22, Issue 5 · 25 May 2026 · 1,310 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Cloud-Based Approach for Privacy-Preserving Medical Image Retrieval: Leveraging Local Features and PCA in Two Efficient StepsM Geetha Yadav, SP ChokkalingamThe major challenges of content-based image retrieval are searching, ranking, and retrieving in secure mode. In this article, we propose a two-step security approach for each database image, utilizing encryption mechanisms and cloud technology. In this approach, the watermark-embedded encrypted images, along with the efficient feature vector database and the list of authenticated users, will be stored in the cloud. … …Journal of Computer Science, Vol. 20, Issue 12 · 4 Nov 2024 · 4,290 accessesView PDFCite
Review ArticleOpen accessIn the keywordsA Comprehensive Survey on Applications, Challenges, Threats and Solutions in IoT Environment and ArchitectureSadia Waheed, Savera Hanif, Rubab Hafeez et al.The influence of the Internet of Things (IoT) on how people live, interact and conduct business has rapidly increased. Integrating physical objects with electronic networking, or the Internet of Things (IoT), allows for better communication and environment detection. In coming years, higher service levels will be offered by IoT-based technologies, remarkably changing how people would conduct their daily lives. Currently, … …Journal of Computer Science, Vol. 20, Issue 3 · 30 Jan 2024 · 7,261 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBidirectional Blockchain-Based Secure Data Transfer Using GALOEEM Routing Protocol in WSNAnitha Rajakumari Ponjothi, Pritee ParwekarData exchange is hampered by the fact that warehouse data are distributed among warehouses. To propose a secure bidirectional blockchain-based data-sharing system that collects warehouse data and controls data sharing through bidirectional transformation. This study is proposed for establishing an efficient bi-directional data warehouse storage for script less blockchains with an infinite lifespan. The sensor provides the data used in … …Journal of Computer Science, Vol. 19, Issue 8 · 20 Jul 2023 · 5,815 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPerformance Analysis of Two Famous Cryptographic Algorithms on Mixed DataEmmanuel Abidemi Adeniyi et al.The rapid development of digital data sharing has made information security a crucial concern in data communication. The information security system heavily relies on encryption methods. These algorithms employ strategies to increase data secrecy and privacy by obscuring the information, which only those parties who have the accompanying key can decode or decrypt. Nevertheless, these methods also use a lot … …Journal of Computer Science, Vol. 19, Issue 6 · 29 May 2023 · 6,020 accessesView PDFCite

Research ArticleOpen accessIn the keywordsSecure Symmetric Block Cipher Design for Encrypting the Bitcoin Wallets in Cryptocurrencies ApplicationsOmar A. Dawood, Othman I. Hammadi, Falath M. MohammedThis paper proposes a new symmetric secret-key cipher for construction of block cipher model. This new approach is considered as a smart step that can be applied to the long process research of modern designing methods used in developing earlier symmetric algorithms. The present cipher can encrypt block lengths of 128-bit by employing Substitution-Permutation Network (SPN) structure. The present cipher … …Journal of Computer Science, Vol. 15, Issue 5 · 1 Jun 2019 · 8,412 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Secure Model for Storage and Dissemination of Examination Results: A Case Study of Zambia Technical Education Vocational and Entrepreneurship Training AuthorityLister Mseteka, Jackson PhiriMost developing countries and public higher institutions of learning have low levels of Information and Communication Technology (ICT) and hence face challenges in securing information and information systems. Therefore, dissemination of examination results through web and mobile applications usually raise security concerns on how to ensure the confidentiality, integrity and authenticity of students’ examination results due to susceptibility of web … …Journal of Computer Science, Vol. 15, Issue 2 · 1 Feb 2019 · 8,058 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSegmented Block Cipher Algorithm Based on ASCII-Codes ManeuverShadi Rasheed Masadeh, Hamza Abbass Al-SewadiDue to their complexity, computation time and power requirement, the secure and widely used cryptographic systems such as 3DES and AES may not be considered suitable for applications like mobile and remote sensing of sensitive data. Therefore, secure but less complicated algorithms for data encryption are still sought. This paper suggests a new Segmented Block Cipher Algorithm (SBCA) is a … …Journal of Computer Science, Vol. 13, Issue 12 · 15 Dec 2017 · 6,899 accessesView PDFCite
