ABSTRACT
Location data containing trajectory information is of great value, but its unrestricted sharing also brings problems such as data abuse, privacy threat and lack of audit evidence. Especially when it comes to researchers or governments to collect location data to stem the spread of COVID-19, the authorization of the data owner is often missing. In this paper, we propose a data sharing scheme for location data based on a high-performance consortium blockchain combined with proxy re-encryption, which can guarantee location data sharing under user authorization while ensure the efficiency and security in the process of data sharing. The performance analysis and simulation results illustrate that the proposed scheme can meet the performance requirements in practical scenarios, guarantee the privacy of personal location data while making the data useful for stemming the spread of COVID-19. © 2022 ACM.
