Blockchain Based E-Voting System

Increasingly digital technology in the present helped many people lives. Unlike the electoral system, there are many conventional uses of paper in its implementation. The aspect of security and transparency is a threat from still widespread election with the conventional system (offline). General elections still use a centralized system, there is one organization that manages it. Some of the problems that can occur in traditional electoral systems is with an organization that has full control over the database and system, it is possible to tamper with the database of considerable opportunities. Blockchain technology is one of solutions, because it embraces a decentralized system and the entire database are owned by many users. Blockchain itself has been used in the Bitcoin system known as the decentralized Bank system. By adopting blockchain in the distribution of databases on e-voting systems can reduce one of the cheating sources of database manipulation. This research discusses the recording of voting result using blockchain algorithm from every place of election. Unlike Bitcoin with its Proof of Work, this thesis proposed a method based on a predetermined turn on the system for each node in the built of blockchain

Ethereum Blockchain based Secure E-voting System

The security and accountability issues are a challenge to the traditional structure from still widespread elections. General e-voting system use a centralized system, where one organization manages overall system. These organisations have full control over the database and system, allowing manipulation of the database. There should be no e-voting system to secure data and potential attacks should be able to withstand. Blockchain technology should solve certain voting problems. In this paper we are implementing an ethereum blockchain based electronic voting system. Ethereum blockchain networks are used to transfer money and store data. Networks are organized by one or more machines. Every node is a machine that running an ethereum client. The eligible one can run the node. By adopting blockchain in e-voting system database distribution, one of the cheating sources of database manipulation and data loss can be reduced. This can be a better solution for the currently existing issues over rigging the electronic voting machines to win elections by the political parties in our government

Database Secure Manipulation based on Paillier’s Homomorphic Encryption (DSM-PHE)

The objective of this research was to suggest some simple solution to increase database manipulation security. Based on advantage of Homomorphic encryption, user’s data in database is always encrypted by Homomorphic encryption algorithm such as Paillier. User’s data is manipulated or processed on many times such as addition, subtraction, multiplication and division. By the advantage of Homomorphic encryption algorithm, user’s data were no need to decrypt while it was manipulated therefore secrecy of data was still reserved. Unfortunately, Paillier’s Homomorphic encryption is normally coverage only addition and multiplication mathematical data operation. This paper suggests simple technique to enhance Pailler’s encryption algorithm to perform data operation as well in subtraction and division operation. Evaluation in suggested data base manipulation, DSM-PHE, indicates that its operation tasks was five operation times more than ordinary data base manipulation operation tasks, without any encryption. Therefore DSM-PHE should be especially used in more sensitive data.

INFORMATION AND EDUCATIONAL ENVIRONMENT FOR MONITORING AND FORMING A CUMULATIVE ASSESSMENT OF A STUDENT’S ACADEMIC WORK IN A SEMESTER

The article discusses the use of the student's cumulative assessment system of academic progress as a valid element of e-learning in universities. Today, online learning is becoming mainstream. Training on online platforms is convenient and interesting, however, it is not acceptable for all students due to the need to conclude network contracts or lack of regulations on how to recalculate the results of online training at the university, etc. Using the cumulative system becomes the mechanism that solves the issue of e-learning at universities, including using distance learning technologies, without cooperating with the online platforms. The suggested approach is a new one. The purpose of the article is to study the electronic information and educational environment of the university to monitor the students’ progress. The recommended assessment means the cumulative assessment, which reflects the consistency of knowledge of the student as a participant in the training process. The recommended assessment is suggested by the information system and is calculated using a mathematical model that considers all types of student work. The assessment becomes the main one and should be considered during an interim assessment. The study of the recommended assessment formation uses the methods of mathematical statistics, data grouping, associative data sets, data verification, database manipulation. The authors also give an optimal strategy for storing large amounts of data based on minimizing their volume while maintaining the necessary access speed.
