TL;DR: This paper proposes a novel privacy-preserving mechanism that supports public auditing on shared data stored in the cloud that exploits ring signatures to compute verification metadata needed to audit the correctness of shared data.
Abstract: With cloud storage services, it is commonplace for data to be not only stored in the cloud, but also shared across multiple users. However, public auditing for such shared data --- while preserving identity privacy --- remains to be an open challenge. In this paper, we propose the first privacy-preserving mechanism that allows public auditing on shared data stored in the cloud. In particular, we exploit ring signatures to compute the verification information needed to audit the integrity of shared data. With our mechanism, the identity of the signer on each block in shared data is kept private from a third party auditor (TPA), who is still able to verify the integrity of shared data without retrieving the entire file. Our experimental results demonstrate the effectiveness and efficiency of our proposed mechanism when auditing shared data.

TL;DR: A blockchain-based decentralized framework for crowdsourcing named CrowdBC is conceptualized, in which a requester's task can be solved by a crowd of workers without relying on any third trusted institution, users’ privacy can be guaranteed and only low transaction fees are required.
Abstract: Crowdsourcing systems which utilize the human intelligence to solve complex tasks have gained considerable interest and adoption in recent years. However, the majority of existing crowdsourcing systems rely on central servers, which are subject to the weaknesses of traditional trust-based model, such as single point of failure. They are also vulnerable to distributed denial of service (DDoS) and Sybil attacks due to malicious users involvement. In addition, high service fees from the crowdsourcing platform may hinder the development of crowdsourcing. How to address these potential issues has both research and substantial value. In this paper, we conceptualize a blockchain-based decentralized framework for crowdsourcing named CrowdBC, in which a requester's task can be solved by a crowd of workers without relying on any third trusted institution, users’ privacy can be guaranteed and only low transaction fees are required. In particular, we introduce the architecture of our proposed framework, based on which we give a concrete scheme. We further implement a software prototype on Ethereum public test network with real-world dataset. Experiment results show the feasibility, usability, and scalability of our proposed crowdsourcing system.

TL;DR: This research explores the two alternative antecedents to Internet privacy concerns and intention to engage in e-commerce activity and contributes to the understanding of Internet privacy and its importance in the global information environment.
Abstract: This study focuses on antecedents to Internet privacy concerns and the behavioral intention to conduct on-line transactions. Perceptions of privacy are socially constructed through communication and transactions with social entities over a networked environment, a process that involves a certain level of technical skill and literacy. The research model specifies that social awareness and Internet literacy are related to both Internet privacy and intention to transact. Survey data collected from 422 respondents were analyzed using structural equation modeling (SEM) with LISREL and provided support for the hypothesized relationships. Social awareness was positively related and Internet literacy was negatively related to Internet privacy concerns. Moreover, Internet privacy concerns were negatively related and Internet literacy positively related to intention to transact on-line. This research explores the two alternative antecedents to Internet privacy concerns and intention to engage in e-commerce activity and contributes to our understanding of Internet privacy and its importance in the global information environment. The construct of social awareness can be broadened to develop a much-needed construct of awareness in MIS research related to the voluntary usage of information technology. A segmentation of Internet users with respect to privacy concerns is also proposed.

TL;DR: With the revelation that Facebook handed over personally identifiable information of more than 87 million users to Cambridge Analytica, it is now imperative that comprehensive privacy policy laws be developed.
Abstract: With the revelation that Facebook handed over personally identifiable information of more than 87 million users to Cambridge Analytica, it is now imperative that comprehensive privacy policy laws be developed. Technologists, researchers, and innovators should meaningfully contribute to the development of these policies.
