Research ArticleOpen accessPhrase in the titleEfficient Text Data Hiding Technique Using Cryptography and SteganographyNor Fazlida Mohd Sani, Mohamad Adreen NujjaidSteganography serves as a technique for covertly embedding confidential information within other data, ensuring that both the existence and content of this hidden data remain undisclosed to unauthorized parties. Its applications span diverse domains, including military operations, online payment systems, and the Internet of Things (IoT). Steganography proves highly adaptable in concealing data, as information with an unknown presence escapes … …Journal of Computer Science, Vol. 21, Issue 1 · 3 Dec 2024 · 5,986 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEnhancing the Robustness of Visual Degradation Based HAM Reversible Data HidingHabiba Sultana, A.H.M. Kamal, Mohammad Mahfuzul IslamPurposely visual degradation of image quality is a newfangled idea in the area of Histogram Association Mapped (HAM) reversible data hiding. Such scheme first divides the color scale, i.e., 0-255, into some partitions by the range, difference of minimum and maximum value of a block. Next, the histogram of a block resided to a partition, original partition, is moved, e.g., … …Journal of Computer Science, Vol. 12, Issue 2 · 26 Mar 2016 · 6,985 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleModules Over Rings of Small Characteristics and Maximality of Data Hiding ratio in CPTE SchemesPhan Trung Huy, Cheonshik Kim, Nguyen Hai ThanhIntroduced CPT scheme as a block-based hiding scheme based on the ring of the integers modulo 2r, which permits to embed r = ⌊log2(k+1)⌋ secret bits in F by changing at most two entries, while the highest number of secret bits in any CPT-based schemes is MSDR2 = ⌊log2(1+k (k+1)/2)⌋, approximately 2r-1. This ratio can be reached approximately in our … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 6,706 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHiding a Large Amount of Data with High Security Using Steganography AlgorithmNameer N. EL-EmamThis study deals with constructing and implementing new algorithm based on hiding a large amount of data (image, audio, text) file into color BMP image. We have been used adaptive image filtering and adaptive image segmentation with bits replacement on the appropriate pixels. These pixels are selected randomly rather than sequentially by using new concept defined by main cases with … …Journal of Computer Science, Vol. 3, Issue 4 · 30 Apr 2007 · 8,617 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFull Capacity Image Steganography Using Seven-Segment Display Pattern as Secret KeyMohammed A. Fadhil Al-Husainy, Hamza Abbass A. Al-SewadiDue to the vast interchange of images over the internet, exchanging secret message hidden in these images would be encouraged and the technique is referred to as image steganography. Hiding the secret data into the least significant bits of the images pixels is a common practice. However, the choice of the hidden key and the efficiency of utilizing all pixels … …Journal of Computer Science, Vol. 14, Issue 6 · 14 Apr 2018 · 7,851 accessesView PDFCite
Research ArticleOpen accessIn the keywordsApplication of T-Code, Turbo Codes and Pseudo-Random Sequence for SteganographyAnil Kumar, Navin RajpalIn this study, we propose new technique that will address the problem of robustness and data safety in steganography. The steganography consists of techniques to allow the communication between two persons, hiding not only the contents but also the very existence of the communication in the eyes of any observer. T-Codes used with Turbo Codes generates cryptic and error-coded data … …Journal of Computer Science, Vol. 2, Issue 2 · 28 Feb 2006 · 7,079 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDigital Video Watermarking in the Discrete Cosine Transform DomainSadik Ali M. Al-Taweel, Putra Sumari, Saleh Ali K. Alomari, Anas J.A. HusainProblem statement: Nowadays, digital watermarks have recently become recognized as a solution for protecting copyright of the digital multimedia. For a watermark to be useful, it must be perceptually invisible and robust against any possible attack and image processing by those who seek to corsair the material, researchers have considered various approaches like JPEG compression, geometric distortions and noising. Approach: … …Journal of Computer Science, Vol. 5, Issue 8 · 31 Aug 2009 · 7,246 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Computational Efficiency Analysis of LSB and Hybrid Steganographic MethodsDivya Sharma, Chander PrabhaElectronic Medical Images (EMI) are of various types such as X-rays, CT scans, MRIs, etc. EMIs are generally large, but they vary in dimensions and sizes based on the body part to which they belong. Not much research has been done to secure EMIs due to their varied and large sizes, while ensuring their accessibility for real-time transmission. Where access … …Journal of Computer Science, Vol. 21, Issue 10 · 28 Nov 2025 · 2,458 accessesView PDFCite
Research ArticleOpen accessIn the abstractCloud Privacy Preservation Using Improved Squeezenet Based Data Sanitization and Improved Lyrebird Optimization-Based Optimal Key GenerationSmita Sharma, Sanjay TyagiMaintaining privacy in the cloud is critical, which implies reliable and effective models that are adapted to the difficulties presented by cloud settings. This paper introduces a comprehensive privacy preservation model tailored specifically for cloud environments, comprising five important phases such as data acquisition, normalization, feature extraction, sanitization and restoration. It begins with the meticulous collection of data from diverse … …Journal of Computer Science, Vol. 21, Issue 7 · 20 Aug 2025 · 3,190 accessesView PDFCite
Research ArticleOpen accessIn the abstractArabic Text Steganography Using Unicode of Non-Joined to Right Side LettersAtef A. ObeidatSteganography is a technique for hiding data in media in a way that makes its existence hard to detect. Text files are a preferable format for use in steganography due to the small storage size of such files. This paper presents an Arabic text steganographic algorithm based on Unicode. The algorithm imposes a minimal change on connected letters without any … …Journal of Computer Science, Vol. 13, Issue 6 · 24 Jun 2017 · 7,540 accessesView PDFCite
