Self-Sovereign Identity is an emerging, user-centric, decentralized identity approach utilizing some form of decentralized technology. It provides a means for digital identification without reliance on any external authority, enabling entities to control their identity and data flow during digital interactions while enhancing security and privacy. With the rise of blockchain technology, Self-Sovereign Identity is gathering momentum in academia and industry while the number of research papers increases rapidly. However, Self-Sovereign Identity is still a young unstructured field in its early stages of research. Thus, a systematic mapping methodology was adopted to provide a coarse-grained overview of decentralized and Self-Sovereign Identity and structure the research area by identifying, analyzing, and classifying the research papers according to predefined parameters, which is to say according to their contribution, application domain, IT field, research type, research method, and place of publication. Furthermore, the nature and scope of the research were determined, while existing research topics, gained insights into trends, demographics, challenges, gaps, and opportunities for future research were also presented. The results suggest that validation research and solution proposals prevail, addressing decentralized identity in a general matter. Papers mainly propose systems/solutions, architectures, and frameworks, focusing on authentication, security, privacy, and trust, while there are hardly any studies researching usability, user experience, patterns, and good practices.

Decentralized and Self-Sovereign Identity: Systematic Mapping Study

The utilisation of blockchain has moved beyond digital currency to other fields such as health, the Internet of Things, and education. In this paper, we present a systematic mapping study to collect and analyse relevant research on blockchain technology related to the higher education field. The paper concentrates on two main themes. First, it examines state of the art in blockchain-based applications that have been developed for educational purposes. Second, it summarises the challenges and research gaps that need to be addressed in future studies.

Blockchain-Based Applications in Higher Education: A Systematic Mapping Study

PurposeThe successive waves of the Covid-19 SARS-II pandemic and the attendant lockdown imposed by the governments worldwide drove the economic activities to a halt. Offices and factories closed, production of goods and services declined and supply chains got severely disrupted. Many companies were embattled with the grim reality of shrinkage of aggregate demand, first due to supply shock and later due to loss of jobs and wages. Amidst all this, the handling and shipping of commodities became extremely complex. As the pandemic shifted consumer preference in favour of digital platforms, more and more fast-moving consumer goods (FMCG) companies were confronted with multiple strategies and choices of an appropriate distribution channel to ensure smooth delivery of raw materials and products. The present study aims to study this shift and its implications in the Indian context.Design/methodology/approachA mix-method approach, integrating quantitative and qualitative analysis, is employed to investigate the factors influencing the selection of distribution channels amongst general trade, modern trade, e-commerce and hyperlocal for FMCG companies in India. The first phase of the study uses exploratory factor analysis (EFA), followed by the application of analytical hierarchy process (AHP) approach in a fuzzy environment to realise the priority weights and ranking of the identified factors. Finally, sensitivity analysis is performed to confirm the robustness of the fuzzy analytical hierarchy process (FAHP) outcomes.FindingsThe study revealed that modern trade has emerged as the most favoured channel in the post-pandemic Indian economy. It has the potential to disrupt general trade. The study also revealed that the hyperlocal delivery model is not economically viable, and the partnership of FMCG companies with these applications is at best a short-term solution. However, it must be submitted that due to its sheer capability to ensure quick deliveries within a confined geographic area, hyperlocal delivery will gain momentum with the advancement of technology.Originality/valueThis study can be seen as the first attempt to investigate the issues related to the selection of the distribution channels in the FMCG sector of India using multi-criteria decision-making technique (MCDM).

Assessing the feasibility of hyperlocal delivery model as an effective distribution channel

Identity management is the set of policies, processes, and technologies used for managing access to information systems, safeguarding digital data, and tracking system activities. The existing Identity management system is not that secure, reliable, distributed and trustworthy. All these systems containing digital information are vulnerable to getting hacked or sometimes act as a malicious entity if the data is altered on central servers. Data breaches, including confidential data, are happening regularly. Blockchain on the other hand is one of the most emerging technologies that has gained a lot of attention in the past 5–6 years. Blockchain can address most of the issues with the existing identity management system. Over few years, various dApps have been created using Blockchain Framework (leveraging PKI system) to solve the problem of Digital Identity Management, but at the same time, most of the work done is compromising the feature of decentralization (systems based on Centralization as Verifiable Credentials / Public-Private Keys are stored in the central server for verification). In this system, the authors have proposed an interoperable blockchain solution for Identity Management. The purpose of this research work is to study the feasibility of whether or not we can use interoperable blockchain solutions for Identity and Access Management. The authors were able to create a PoC for illustrating the same. This system was able to complete the authentication and verification process within 1 second, and all the necessary functions created to test the feasibility was able to execute within 1 second. Also in this system authors have achieved full decentralization.

Interoperable Blockchain Solution For Digital Identity Management

The development and growth of blockchain technology today have gained widespread attention from researchers and practitioners. This popularity is due to the various positive benefits of this technology in multiple sectors such as finance, public administration, health care, education, science, culture, and the arts. Various studies have been conducted to examine the application of blockchain technology in the education sector. However, there are still many hidden things and research areas that have not been discussed. This literature review will discuss blockchain applications in the process of education management. This literature study focuses on answering three main questions: what type of application blockchain technology is used for, what kind of data is stored using blockchain, and unresolved constraints or challenges in adopting and implementing blockchain technology in education. The results of our study show that there is great potential that this technology can bring to education. We also found and discuss solutions to various challenges in certain data types and problems in implementing this technology in education management. The results of this literature study are aimed at researchers interested in carrying out research using blockchain technology in education by providing an overview of what needs to be done for further research.

Review of Blockchain Application in Education Data Management

In recent years, there have been many difficulties occurred in the field of education from school to universities while conducting exams. Fraudulent activities can be identified in this field and it leads to reduce trust in the quality of the education system. Most of the scandals are based on the abuse of personal information systems and the user’s data breaches occur and affect the security as well as privacy. In this research work, we propose a high-level framework of the block chain-based identity management system. In Hyperledger Indy using plenum based RBFT protocol the framework will be created. RBFT algorithm in block chain mechanism provides trust and security and complete transparency in the whole system. In this paper, we proposed the secured identity management system and a human intervention could not affect the user’s data system and makes the security even with better results.

An Efficient System Framework for Managing Identity in Educational System based on Blockchain Technology

A large growing market now revolves around selling perishable products such as meat, including poultry and seafood. Virtually many/every kind of fresh meat has been available for customers or purchasers from online vendors, there is very little research that examines the handling, safe delivery that influences this unorganized sector [1]. The purpose of my paper revolves around analyzing the policies for delivering online raw meats by the purveyors of this product. And also, to emphasize the food safety data that are given on the websites of online sellers for this particular sector. Hence, I thought of this website that meets the need of the current Digital Market and is convenient to its users. "WOW SHOPPER" enables the user to browse the range of products along with information about the product's specifications, features, and prices. The digital environment has a growing effect on consumers' minds and buying behavior, this is what makes our website feasible to the current scenario.

In today's world, email spam has become a serious concern, since the number of internet users has grown rapidly. Illegal and unethical practices, such as phishing and fraud, are taking advantage of the diverse classes of users that use different web services. Users that send unsolicited emails with the intention of disrupting or attracting legitimate customers are known as "spammers" by infecting the user system by sending malicious links in a spam email. Spammers prey on those who are unaware of their deceptions by posing as real people in their unsolicited emails and setting up bogus social media profiles and email accounts. These fraudulent spam emails must be identified. The work is an attempt to analyze different machine learning approaches to serve the purpose. This article uses Deep Learning methods for the identification of spam emails with high precision and accuracy.
