A Novel Method of Invisible Video Watermarking Based on Index Mapping and Hybrid DWT-DCT

International Journal of Online and Biomedical Engineering (iJOE), Год журнала: 2023, Номер 19(04), С. 155 - 173

Watermarking is widely used in multimedia preservation and communication, which comprises, therefore not limited to, data security validation. Security, readability, imperceptibility, resilience are some of the key advantages this technology. However, there still certain issues that need to be addressed, such as ability withstand a variety assaults without substantially affecting quality value embedded data. Based on its operational domain, watermarking technology may divided into two groups: spatial frequency watermarking. An index mapping-based approach for copyright protection multi-media color videos presented paper. We offer hybrid discrete wavelet transform cosine (DCT) algorithm digital video watermark. Peak signal noise ratio (PSNR), similarity structure measure (SSIM), have been analyze distortion produced by It suggested proposed method provides greater imperceptibility conjunction with each other human visual system it offers higher robustness against different attacks.

One of the major capabilities blockchain technology is sharing data in verifiable ways without losing control information possession. Issuing and verifying student certifications for higher study applications or job recruitment require many steps that take days to complete are considered time-consuming. Most universities around world use centralized systems entire procedure when a graduate applies postgraduate studies. Applying certificate verification protocols through comprehensive architecture provides authenticity reduces time significantly. In this paper, framework has been proposed issue locally addition them across internet while maintaining ownership certifications. This leverages advantages electronic certification verification. blockchain-based system will provide low latency issuing, sharing, these The paper presents e-certification an evaluation framework, which consists measuring average transaction time.

Digital Citizenship (DC) is a set of rules, controls, standards, norms, ideas, and principles followed in the optimal proper use technology, which citizens, young old, need to contribute progress nation. In short, it guidance protection, benefits modern technologies, protection from their dangers. Or more precisely, smart approach technology. The concept digital citizenship has strong relationship with education system, so academics higher scientific research institutions must be most experienced, effective among students this field. Especially after Corona pandemic trend that universe gone through towards using internet all areas life, including education, especially integrated become very important for citizen digital. This study dealt sample university professors (200) questionnaires. All who belong colleges human specialization possess citizenship. There are no differences between gender except axis, was favor teaching staff male. addition specialization, science.

The Iraqi power sector is at a critical stage that requires urgent reforms. Concerns regarding the ability of system to provide steady and its operational inefficiencies, in general, have been expressed by industry academia. Currently, experiencing one highest demand growth world, given it capital intensive, takes up large share Iraq's government investment program. More so, there huge increase financial burden electricity supply due high subsidies required for coverage recurrent expenditure. This subsidy regarded as extremely low traffic which does not cover 20% periodic Apart from tariff, another major indirect socioeconomic fact over-staffed with over 50,000 employees under normal circumstances should be more than 15,000. estimated annual cost aforementioned inefficiencies insufficient about $3 4 billion. In 2013, 70% generated was lost, this loss three areas, including commercial, technical, administrative losses. Therefore, need massive reforms are targeted addressing entire issue. can achieved through engagement private sector, higher competition, introduction novel regulatory legislative frameworks. addition that, available sources energy Iraq optimized alongside gas usage related oil extraction, while solar explored hybridization current stations.

USING SPECIAL LETTERS AND DIACRITICS IN STEGANOGRAPHY IN HOLY QURAN

Iraqi Journal for Computers and Informatics, Год журнала: 2023, Номер 49(2), С. 1 - 8

Опубликована: Авг. 14, 2023

Because of the great development that took place in information transfer and communication technologies, issue security has become a very sensitive resonant issue, importance must be given to protecting this confidential information. Steganography is one important effective ways protect while it being transmitted through Internet, steganography technology hide inside an unnoticeable envelope object can image, video, text or sound. The Arabic language some special features make excellent covers from Through diversity letters dotted several forms vowels letters, Holy Qur’an considered cover rich movements grammar, which makes wide for purpose concealing sacred book where not permissible modify, add move any diacritical mark it. algorithm hides two bits by uses six language. Moreover, checks presence specific linguistic referred diacritics. proposed system achieved high ability as Surat Al-Baqarah (4524 bits) also (2576 Al-Imran Al-An’am (2318 bits).

Mathematical connection skills and their relationship with productive thinking among secondary school students

Periodicals of Engineering and Natural Sciences (PEN), Год журнала: 2022, Номер 10(1), С. 421 - 421

Опубликована: Фев. 7, 2022

In recent times, it has increasingly become imperative to demonstrate the function which mathematics plays in different aspects of life general, especially terms solving problems and decision-making. Mathematics is applied that individuals society at large are faced with daily. Also, a crucial role lives students by enabling them prepare for challenges through creation positive interaction between real-life situations, development their mental capabilities problem-solving creativity. It also helps be responsible develop self-confidence. This research seeks find out whether there correlation learners' ability connect its branches other sciences, as well daily think productively. achieved using two statistical tests, whereby one tests used determining mathematical connection skills possessed learners, while employed measure productive thinking among learners. A sample 300 fourth-grade science from Baghdad was study. The results analyses revealed skill positively correlated thinking.

Image Encryption Based on Multi-Level Keys on RC5 Algorithm

International Journal of Interactive Mobile Technologies (iJIM), Год журнала: 2022, Номер 16(17), С. 101 - 115

Опубликована: Сен. 8, 2022

In recent years, the need to develop encryption algorithms has led an increase in working and efficiency of protect transmission reception information from any security breach. The RC5 type algorithm is most common closest perfection symmetry algorithms, knowing that it faces many problems which data collection was limited because occurs only twice by on its also, used for 1 function (XOR) through process. A research report digital image development developing makes more secure adding a new level (using two keys) thus increasing key space. decryption process can be done substituting XOR operation applied Sixteen rounds with (#) based use 2 keys, each consisting 4 states (0,1,2,3) instead using traditional uses (0,1). This increases robustness hacking methods.

International Journal of Online and Biomedical Engineering (iJOE), Год журнала: 2023, Номер 19(01), С. 93 - 106

Опубликована: Янв. 17, 2023

Cyber security is a term utilized for describing collection of technologies, procedures, and practices that try protecting an online environment user or organization. For medical images among most important delicate data kinds in computer systems, the reasons require all patient data, including images, be encrypted before being transferred over networks by healthcare companies. This paper presents new direction encryption method research encrypting image based on domain feature extracted to generate key process. The process started applying edges detection. After dividing bits edge into (3×3) windows, diffusions are applied create used image. Four randomness tests passed through NIST ensure whether generated accepted as true. reversible state decryption retrieve original will gained can any cyber field such comparative experiments prove proposed algorithm improves efficiency has good performance, higher information entropy 7.42 well lower correlation coefficient 0.653.
