Blockchain Technology for Secure Accounting Management: Research Trends Analysis

The scope of blockchain technology, initially associated with the cryptocurrency Bitcoin, is greater due to the multiple applications in various disciplines. Its use in accounting lies mainly in the fact that it reduces risks and the eventuality of fraud, eliminates human error, promotes efficiency, and increases transparency and reliability. This means that different economic sectors assume it as a recording and management instrument. The aim is to examine current and emerging research lines at a global level on blockchain technology for secure accounting management. The evolution of the publication of the number of articles between 2016 and 2020 was analyzed. Statistical and mathematical techniques were applied to a sample of 1130 records from the Scopus database. The data uncovered a polynomial trend in this period. The seven main lines of work were identified: blockchain, network security, information management, digital storage, edge computing, commerce, and the Internet of Things. The ten most outstanding emerging research lines are detected. This study provides the past and future thematic axes on this incipient field of knowledge, which is a tool for decision-making by academics, researchers, and directors of research investment program

Patent analysis for social usage of blockchain

Abstract. This bachelor’s thesis intends to showcase patents related to blockchain that are aimed at individual users or communities. Patents from Europe are specifically an area of interest for this thesis. Patents were searched from European and worldwide patent databases using keywords. Then patents from these searches were analysed individually. Most interesting patents for the scope are examined more in-depth in the thesis

MIGRATING DATA TO THE CLOUD: AN ANALYSIS OF CLOUD STORAGE PRIVACY AND SECURITY ISSUES AND SOLUTIONS

The rise of a digital economy has transformed how individuals do business and carry out daily tasks, including how data is maintained. Because of the vast amount of data that organizations own, cloud storage, a component of the cloud computing paradigm, has emerged as a feasible solution to many businesses\u27 data storage concerns. Despite this, organizations are still cautious about moving all of their data to the cloud due to security concerns, particularly since data management is outsourced to third parties. The aim of this paper is to provide an overview of current challenges in the field of cloud storage privacy and security, with an emphasis on issues related to data confidentiality, integrity, and availability. Using a comprehensive literature study, this research investigates innovative strategies for creating a secure cloud storage environment. The idea of maintaining privacy and data security through the very design of the services, or through the so-called "privacy by design" approach, is explained while avoiding getting into the technical details of how the algorithms and presented solutions work
