BroncoVote: Secure Voting System Using Ethereum’s Blockchain

Voting is a fundamental part of democratic systems; it gives individuals in a community the faculty to voice their opinion. In recent years, voter turnout has diminished while concerns regarding integrity, security, and accessibility of current voting systems have escalated. E-voting was introduced to address those concerns; however, it is not cost-effective and still requires full supervision by a central authority. The blockchain is an emerging, decentralized, and distributed technology that promises to enhance different aspects of many industries. Expanding e-voting into blockchain technology could be the solution to alleviate the present concerns in e-voting. In this paper, we propose a blockchain-based voting system, named BroncoVote, that preserves voter privacy and increases accessibility, while keeping the voting system transparent, secure, and cost-effective. BroncoVote implements a university-scaled voting framework that utilizes Ethereum’s blockchain and smart contracts to achieve voter administration and auditable voting records. In addition, BroncoVote utilizes a few cryptographic techniques, including homomorphic encryption, to promote voter privacy. Our implementation was deployed on Ethereum’s Testnet to demonstrate usability, scalability, and efficiency

Blockchain Solutions for Financial Data Integrity

Since the infamous financial scandals of the early 2000s, business regulatory agencies have established increasingly stringent regulations for public companies to follow. Controls over financial data have become imperative for companies to maintain. Current data management systems would greatly benefit from advances in blockchain technology, strengthening controls over data integrity and data availability. This paper proposes a blockchain-based framework to verify the integrity of financial information. This framework, Akeraiotita, leverages smart contracts in an Ethereum-based blockchain to confirm financial data have been unaltered; the framework allows companies to layer blockchain technology on top of their current data management systems. Two systems are proposed: the first, Eunomia, is for a company to use internally; the second, Eulabeia, is for companies to post transactions with third parties. The goals of this paper are to analyze how Akeraiotita would interact with a company’s current data management system, allow companies to post transactions to a global blockchain, and understand how the framework could address longstanding transactional security concerns

Privacy-Preserving Framework for Access Control and Interoperability of Electronic Health Records Using Blockchain Technology

Despite an increased focus on the security of electronic health records and an effort by large cities around the globe to pursue smart city infrastructure, the private information of patients is subject to data breaches on a regular basis. Previous efforts to combat this have resulted in data being mostly inaccessible to patients. Existing record management systems struggle with balancing data privacy and the need for patients and providers to regularly interact with data. Blockchain technology is an emerging technology that enables data sharing in a decentralized and transactional fashion. Blockchain technology can be leveraged in the healthcare domain to achieve the delicate balance between privacy and accessibility of electronic health records. We propose a blockchain-based framework for secure, interoperable, and efficient access to medical records by patients, providers, and third parties, while preserving the privacy of patients\u27 sensitive information. Our framework, named Ancile, utilizes smart contracts in an Ethereum-based blockchain for heightened access control and obfuscation of data, and employs advanced cryptography techniques for further security. The goals of this project are to analyze how Ancile would interact with the different needs of patients, providers, and third parties, and to understand how the framework could address longstanding privacy and security concerns in the healthcare industry

GenVote: Blockchain-Based Customizable and Secure Voting Platform

Electronic voting has been popularized in recent years as an alternative to traditional voting. Even though electronic voting addresses the problems that traditional voting brings, it is not a perfect solution. Electronic voting brings its own set of concerns which include: election fraud, voter privacy, data integrity, and confidentiality. To ensure fairness in electronic voting, a centralized system is required and the complete process has to be overseen by an authority. Due to these requirements it can be very expensive to roll-out on a large scale during every voting period. Blockchain, the distributed data structure popularized by Bitcoin, can be integrated into electronic voting systems to alleviate some the problems involved with them while being cost-effective. With the use of blockchain, we propose a voting system that is easily accessible, customizable, transparent, and in-expensive. GenVote is a distributed electronic voting system that utilizes Ethereum Blockchain, smart contracts, and homomorphic encryption to achieve a transparent voting process with non-authority based tallying and voter privacy. GenVote also allows the ballot creation and voting process to be customizable with different types of ballots and logic based voting. GenVote is currently a viable solution for university-scaled elections and has been deployed on Ethereum Ropsten testing network to evaluate its viability and scalability as an electronic voting system
