Cloud computing has made the software development process fast and flexible but on the other hand it has contributed to increasing security attacks. Employees who manage the data in cloud companies may face insider attack, affecting their reputation. They have the advantage of accessing the user data by interacting with the authentication mechanism. The primary aim of this research paper is to provide a novel secure authentication mechanism by using Blockchain technology for cloud databases. Blockchain makes it difficult to change user login credentials details in the user authentication process by an insider. The insider is not able to access the user authentication data due to the distributed ledger-based authentication scheme. Activity of insider can be traced and cannot be changed. Both insider and outsider user’s are authenticated using individual IDs and signatures. Furthermore, the user access control on the cloud database is also authenticated. The algorithm and theorem of the proposed mechanism have been given to demonstrate the applicability and correctness.The proposed mechanism is tested on the Scyther formal system tool against denial of service, impersonation, offline guessing, and no replay attacks. Scyther results show that the proposed methodology is secure cum robust.

The key objectives of this paper is to propose a design implementation of blockchain based on smart contract which have potential to change international mobile roaming business model by eliminating third-party data clearing house (DCH). The analysis method used comparative analysis between current situation and target architecture of international mobile roaming business that commonly used by TOGAF Architecture Development Method. The purposed design of implementation has validated the business value by using Total Cost of Ownership (TCO) calculation. This paper applies the TOGAF approach in order to address architecture gap to evaluate by the enhancement capability that required from these three fundamental aspect which are Business, Technology and Information. With the blockchain smart contract solution able to eliminate the intermediaries Data Clearing House system, which impacted to the business model of international mobile roaming with no more intermediaries fee for call data record (CDR) processing and open up for online billing and settlement among parties. In conclusion the business value of blockchain implementation in the international mobile roaming has been measured using TCO comparison between current situation and target architecture that impacted cost reduction of operational platform is 19%. With this information and understanding the blockchain technology has significant benefit in the international mobile roaming business.

The purpose of the article. The article considers the Blockchain technology asan innovative tool. In particular, the essence and background of the developmentof blocks, the principles and specifics of the functioning of the system, as well asthe scheme of its work, are determined. The article presents the prospects forusingdistributed registry technologies (blockchain) in various socioeconomic spheresrelated to state administration. Provided examples and forecasts of the use ofblockchain technologies in the provision of state and municipal services forindividuals and legal entities in the following areas: formation of a unified registercontaining the history of the placement of the state, municipal order, as well asprocurement of corporations with state participation and / or control; registers ofdocuments (diplomas, certificates, lost and disavowed passports, policies for movableand immovable property insurance, health, etc.); database of court decisions andexecutive proceedings; public participation portals for citizens of Ukraine district- city – country. The fact that the blockchain technology is, first of all, theprinciples, and not the only possible way of implementing them, allows us to counton maximum openness and multivariate application in a dynamically changingchanging«digital world». Methodology. The research methodology is to use a combinationof methods: analytical, historical, comparative. The scientific novelty. The priorityof state blockchain systems introduction in stationary and distant voting, distributeddocument circulation, medical data registration, land resources registration,electronic auctions (auctions) in Ukraine was grounded. Conclusions. Already today,blockchain systems can change the role and participation of citizens in the conductof the state-management process, by raising the responsibility level, from thetransparent will expression in the elections to regulating the government serviceactivity in the society’s digitization conditions. The main advantages blockchainsystems using by public authorities that will increase the level of citizens trust todigital technologies using in general, namely: reliability and reliability of datastorage, transparency of transactions and virtually absolute protection of informationfrom distortion and unauthorized removal (relocation), are determined. In furtherscientific research it is proposed to consider the promising areas of the blockchaindigital technology usage: service activities of public authorities, legal proceedings,property rights management, implementation of migration control, verification ofgoods and services, registration of data on passing qualifying tests, patenting,intellectual property, digital identification, logistics , taxation, accounting ofbudget funds movement.

AbstractOur contemporary world is on the verge of crucial changes of an unparalleled pace. The ‘technological changeover’ is the new paradigm caused by the unprecedented evolution of the disruptive technologies. The present world has the tendency to evolve at least exponential, therefore future educational environment is fairly different than its present layout. An entire array of nowadays studies widely recognizes that the progress of the disruptive technologies will pose a meaningful impact over the educational system evolution. Among the most spectacular technologies with disruptive features we should encounter Artificial Intelligence, Blockchain Technology, Cloud Computing, and the like. In an era of technological disruption the education is seen as the new currency. With the help of Artificial Intelligence, for instance, the education system could track how people learn from kindergarten to retirement. Besides, the technology domain will move the centre of gravity from the institutional area to that of the education’s beneficiaries, as we might expect that they will recruit and employ the needed teacher staff, not the institutions. Moreover, the education’s recipients will be the main creators of tomorrow’s professions and within their community the overarching events will happen and the main decisions will be taken in the educational domain.
