Election absenteeism rates are steadily rising, partly a result of the distance required to cast a vote. The use of electronic voting procedure would eliminate the need for travel and enhance voter turnout. In addition, compared to the conventional paper ballot voting technique, this reduces dangers like manipulations and produces results more quickly. A remotely electronic voting system should, nevertheless, adhere to the highest standards of security, dependability, and transparency given the significance of an election. Numerous remote e-voting systems, many of which are based on blockchain technology, were examined in this literature review. Blockchain technology provides for the removal of the Trusted Third Party (TTP) and the decentralization of transactions while also providing transparent and completely secure data storage, making it a new technical foundation for many different types of IT applications. The use of smart-contract technology, which automates and executes user agreements, is also permitted. The authors of this study examine the most insightful blockchain-based e-voting options. The lack of openness and auditability in conventional voting methods can be addressed by blockchain technology. A reliable computing platform is offered by running a self-enforcing e-voting system on a blockchain for real-time data verification

“…This scheme can effectively reduce the transmission delay but does not consider large-scale decentralized energy transactions. Garg et al [21] designed a key agreement protocol based on mutual authentication by fully hashing the Menezes-Qu-Vanstone key exchange mechanism combined with an elliptic curve cryptosystem, which can effectively resist denial of service and replay attacks. Thus, communication costs and expenses are considerably reduced.…”

As one of the essential steps to secure government data sharing, Identity Authentication (IA) plays a vital role in the processing of large data. However, the centralized IA scheme based on a trusted third party presents problems of information leakage and single point of failure, and those related to key escrow. Therefore, herein, an effective IA model based on multiattribute centers is designed. First, a private key of each attribute of a data requester is generated by the attribute authorization center. After obtaining the private key of attribute, the data requester generates a personal private key. Second, a dynamic key generation algorithm is proposed, which combines blockchain and smart contracts to periodically update the key of a data requester to prevent theft by external attackers, ensure the traceability of IA, and reduce the risk of privacy leakage. Third, the combination of blockchain and interplanetary file systems is used to store attribute field information of the data requester to further reduce the cost of blockchain information storage and improve the effectiveness of information storage. Experimental results show that the proposed model ensures the privacy and security of identity information and outperforms similar authentication models in terms of computational and communication costs.

“…In different application domains of smart environments, researchers have implemented different types of privacy-preserving identifiers (pseudonyms) to be (re)used for achieving different degrees of data minimisation and anonymity. For instance, transaction pseudonyms are employed in [121] to provide a decentralised ID scheme based on blind signatures and a Bloom filter. Their solution achieves accountability and unlinkability of pseudonyms and is applicable in many application scenarios of smart environments and critical infrastructures such as banks, hospitals, e-voting, etc.…”

Envisioning Usable Privacy in Smart Environments: A Technical and Intercultural Perspective

Smart environments provide users with a large number of new services that will improve their lives, such as smarter and more efficient transportation, advanced smart home services, and pervasive healthcare. Yet, they also have the potential for collecting staggering amounts of personal information, which, if misused, poses a multitude of privacy threats to users ranging from tracking, stalking to monitoring and profiling. Consequently, the users’ right to informational self-determination is at stake in smart environments. Therefore, there is a need for solutions that empower individuals with control over their data in smart environments. Privacy-Enhancing Technologies (PETs) and privacy by design and by default can help to protect users’ privacy. In particular, usable Privacy-Enhancing Identity Management (PE-IdM) can re-establish user control and, thus, informational self-determination by offering users a selection of meaningful preference-based privacy settings that they could choose from to lessen the configuration burden of privacy settings. However, different privacy trade-offs need to be considered and managed for the configuration of the identity management system, as well as various factors influencing users’ privacy preferences. Guidelines for the design of usable management of privacy settings that address varying end-user preferences for control, location sharing and privacy conflicting goals are needed. The objective of this thesis is to propose viable approaches for enforcing usable PE-IdM for smart environments, with a focus on vehicular ad hoc networks (VANETs). To that end, we unravel the technical state of the art regarding the problem space and solutions. We employ qualitative and quantitative empirical Human-Computer Interaction (HCI) research methods to investigate different users’ privacy preferences and factors affecting such preferences. Our results demonstrate a cultural and regional influence on willingness to share location data and preferences for trade-offs for location privacy. Based on our results, we elicit end-users and design requirements and propose high-level design guidelines for usable PE-IdM for VANETs. These guidelines aim to simplify privacy and identity management for users by offering selectable settings that will cater for their different privacy needs and preferences.
