Title: A Novel Image Encryption Optimization Technique Authors: Dr.Srividya R Abstract: Abstract— Image file confidentiality is a difficult issue these days for a variety of reasons in a range of industries, including medical, defence, academia, and many more. A range of practical ways have been studied in recent years to safeguard image data, however owing to technological improvements, such existing solutions have significant limits in current systems. Several academics have investigated a number of methodologies and strategies for maintaining picture secrecy and shielding top-secret information from attackers while images are sent via communications infrastructure. In this paper, an unique picture encryption technique based on a chaotic map and DNA encoding is jointly used for image encryption in a more pragmatic approach, as necessary in today's world to safeguard private data. This approach was tried and confirmed on a personal laptop with a 64-bit operating system, Windows 10, with 16 GB RAM and the MATLAB R2020a version loaded (Random Access Memory). The results of this suggested approach reflect the best NPCR (Number of Pixel Change Rate) and UACI (Unified Average Changed Intensity) scores for a variety of selected photos for testing. This method works with a variety of image formats and is in great demand in today's world for safeguarding sensitive data or information while being transmitted across a communications infrastructure. More research is needed in the future to identify practical answers, as current communication networks are quickly changing throughout the world owing to technology breakthroughs.

Title: A Blockchain based Electronic Medical Health Records Framework using Smart Contracts Authors: Vardhini B; Shreyas N Dass; Sahana R Abstract: The common issues in medical services within the country are mostly associated with doctors' referral process, data transfer between health institutions, and portals for patients to access their medical information. Specific issues arise, such as sharing health Records across institutes or hospitals, problems with misuse of data once shared, no security, etc. The Electronic Health Record (EHR) Framework on Blockchain addresses those issues, resulting from a collaboration of all stakeholders involved. This paper explores the likelihood of representing medical records to make sure data privacy, data accessibility, and data interoperability for the healthcare-specific scenario. Data privacy refers to affording protection to ensure data is available when needed and not used, imparted, accessed, altered, or deleted while being stored or retrieved, or transmitted. Data accessibility is the ability to access the data regardless of natural or artificial accidents, hardware, or others. Improving the accessibility of health data in the healthcare sector while ensuring privacy has been identified as a necessary capability that involves every individual and organization. Traditionally, healthcare interoperability has centered on sharing data between business institutions, such as various hospital systems. The emphasis has lately been on patient-driven information sharing, where the exchange of medical information is patient-mediated and patient-driven. We propose implementing a large-scale information infrastructure to access Smart Contracts sponsored by EHRs as information mediators. The decentralized nature of blockchain technology will aid in making the EHR accessible over a broader network. Using Blockchain will help make far- reaching changes in the healthcare industry by providing immutable, authentic, and accessible medical records, privacy, and faster payments.

Title: An Open Source Distributed Virtualization for Enterprise Infrastructure using OVIRT Authors: R.Chinnaiyan; Preetika B Abstract: Virtualization normally suggests the formation of a virtual machine that can virtualize the total of hardware resources, including memory, stockpiling, processors, and organization availability. The necessities referenced from Goldberg and Popek, are that there are three angles to satisfy the virtualization. A proportional domain ought to be given to run a program that appeared differently in relation to a local framework.If the program shows an undeniable lead under virtualization, it may not be recognized as a virtualized situation. An ensured control of virtualized assets ought to be given by virtualization. Having unlimited oversight of assets is essential to guarantee information and assets on each virtual condition from any risks or lead impedance in sharing physical assets. Performance deterioration is normally expected by virtualization, because of the additional assignment for virtualization, anyway satisfactory execution should be accomplished with programming or equipment uphold in taking care of advantaged directions. These points of interest guarantee successful virtualization. In the going with portion, hypervisors and their sorts are clarified with the application level of virtualization. Virtualized resources are additionally introduced in CPU, memory, and I/O exchange. In this paper, we are examining how virtualization happens utilizing the Ovirt motor which incorporates virtualization, the design of virtualization innovation, Virtual Machine just as Hypervisors. Further examining the strategy of virtualization, motivations to utilize virtualization, Importance of Virtualization in conclusion talk about Pros and Cons of Virtualization. This paper shows the significance of virtualization innovation that can streamline IT tasks just as permit IT associations to react quicker to changing business requests.
