Research ArticleOpen accessIn the keywordsExploring Self-Sovereign Identity Through a Digital Transcript Proof-of-ConceptNaphat Khajohn-Udomrith, Ittipon RassameerojCredential forgery presents a significant threat to the integrity of academic and employment documents. While Self-Sovereign Identity (SSI) and Verifiable Credentials (VC) offer a decentralized alternative, existing solutions often struggle to balance institutional trust with holder privacy. This paper proposes a novel, dual-layered architectural framework for digital transcripts. We implement a strategic bimodal DID approach, utilizing did:web for the issuing … …Journal of Computer Science, Vol. 22, Issue 5 · 21 May 2026 · 1,487 accessesView PDFCite

Review ArticleOpen accessIn the abstractState-of-the-Art in Techniques of Text Digital Watermarking: Challenges and LimitationsNasr Addin Ahmed Salem Al-Maweri, Roslizah Ali, Wan Azizun Wan Adnan et al.Data protection from malicious attacks and misuse has become a crucial issue. Various types of data, including images, videos, audio and text documents, have given cause for the development of different methods for their protection. Cryptography, digital signatures and steganography are the most well known technologies used to protect data. During the last decade, digital watermarking technology has also been … …Journal of Computer Science, Vol. 12, Issue 2 · 19 Mar 2016 · 8,526 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Image Generation Algorithm Using Fractals and Chaos TheoryK. Thamizhchelvy, G. GeethaAn Efficient Image Generation Algorithm is proposed. It generates Message Authentication Image (MAI) by using Fractals and chaos theory. The fractal images are generated by using Iterated Function System (IFS) techniques. We implemented and generated the fractal images exploring the properties of chaos. Chaos is an unpredictable behavior arises in a dynamical system so that the future behavior is not … …Journal of Computer Science, Vol. 11, Issue 2 · 10 Sep 2014 · 7,425 accessesView PDFCite
Research ArticleOpen accessIn the abstractLIGHTWEIGHT VIGILANT PROCEDURE TO IMPLEMENT SECURITY MEASURES IN HIGHLY ROVING MILITARY OPERATIONSJ. Udhayan, Rajesh BabuThe performance of Mobile Ad hoc Network (MANET) becomes questionable in highly roving and mission critical application like military operation. Security measures like encryption, authentication, digital signature has been proposed for MANET. However all those mechanisms need some kind of static infrastructure and it is extremely difficult to implement such an infrastructure throughout the military mission. Therefore in this work, … …Journal of Computer Science, Vol. 9, Issue 10 · 18 Sep 2013 · 6,641 accessesView PDFCite
