A Framework of Multilayer Encryption Net with MBBS Generator For Images Encryption

2024-05-30T09:44:13+02:00

Ensuring the security of multimedia information, such as images, is essential due to the rapid development of information technology, so various image encryption algorithms have been proposed to ensure privacy and prevent improper behaviour. This paper presents a proposed model called Multi-Layer Encryption Net (MLE-Net) to encrypt the image based on using a multi-layer net to code the image and modify the Blum-Blum-Shub pseudo-random number generator to generate the keys used in the encryption process. The proposed method is organized into two stages: the first stage is plain-image data pre-processing, and the second stage divides the used image into blocks to be input for a multi-layer encryption network. The proposed method uses secure keys generated by the Modified Blum-Blum-Shub (MBBS) random number generator to improve its accuracy, reduce the complexity, and modify its control parameters to maintain data privacy efficiently and accurately. The outcomes show that the suggested approach successfully provides secure information delivery.

Background: In response to the COVID-19 pandemic, the rapid development of vaccines targeting the SARS-CoV-2 virus has been pivotal. These vaccines work by triggering antibody production to neutralize the virus. This study evaluates the efficacy of available COVID-19 vaccines in Iraq, contributing to public health knowledge in the region.

Methods: A cross-sectional analysis was performed using 1,233 Iraqi participants vaccinated with one of the available vaccines in Iraq, including Pfizer, AstraZeneca, or Sinopharm, and exposed to COVID-19 infection after their immunization. Most clinical evaluations were conducted with all participants.

Results: The study found that Pfizer vaccine recipients predominantly experienced mild COVID-19 symptoms, with fewer cases of moderate or severe symptoms. Those vaccinated with AstraZeneca mainly reported mild to moderate symptoms, with fewer severe or asymptomatic cases. Sinopharm recipients generally showed no symptom frequencies, followed by mild and moderate cases with rare severe symptoms. In contrast, unvaccinated individuals primarily exhibited moderate to severe symptoms, with fewer mild or asymptomatic cases.

Conclusions: The study suggests that COVID-19 vaccines are more effective at preventing severe disease outcomes, such as hospitalization and death, than mild or asymptomatic infections. In Iraq, Sinopharm and Pfizer vaccines were observed to be more effective in reducing severe COVID-19 cases and hospitalizations compared to the AstraZeneca vaccine and unvaccinated individuals.

Healthcare facilities in the modern day are a significant problem, particularly in developing nations where distant locations are hampered by a scarcity of high-quality hospitals and medical professionals. As artificial intelligence has revolutionized several fields of life, it has also had a positive impact on health. The existing architecture is facing several issues for the conventional telemedicine store-and-forward method. These include the requirement for a local health centre with dedicated staff, the need for medical equipment to prepare patient reports, the time constraint of 24–48 hours in receiving diagnosis and medication details from a medical expert in the main hospital, the cost of local health centres, and the requirement for a Wi-Fi connection, among others. Medical gadgets equipped with wireless communication capabilities allow for remote monitoring and are becoming more linked to one another and the Internet. Internet of Intelligent Things-enabled Medical and connected medical devices, also known as IoMT, have allowed continuous real-time patient monitoring, improved diagnostic accuracy, and more effective therapy than ever before. Although these devices have various advantages, they also create new attack surfaces, resulting in an increased number of security and privacy risks, which must be addressed. Attacks against medical equipment that are linked to the Internet have the potential to inflict significant bodily injury and even death on the patients who are targeted. In this study, we examine the strategies that may be used to provide advice on how to safeguard a network of connected medical devices.

Review Article: Comparison of three types of polymers Delrin , Polyester and Nylon

2024-06-04T12:02:26+02:00

This article discusses three types of manufactured polymers: Delrin, nylon, and polyester. Polymers are the product of various forms of raw plastics found in nature, whereas plastics are the names given to chemically human-made polymers. Polymer substances consist of a single unit called a monomer, which binds to millions of other similar molecules to form long chains. The length of these chains, the number of branches, and how closely they relate to each other determine the physical properties of the final plastic Polymers and their privileged position in chemistry due to their chemical and physical properties. The strength of the polymer depends on the number of monomers along the chain, side groups, cross-links and branches. If the polymers consist of only one type of monomer, it is called a homopolymer, and if there is more than one monomer in the polymer series, it is called a copolymer. Increasing the length of the chain polymers leads to a high degree of colour acceptance, describing the existence of polymers with different colours. Many chemical names of polymers were used, such as plastics, and became familiar to consumers.
