The Value of Privacy in Mobile Crowdsourcing
CrowdsourcingĀ systems often include someĀ negativeĀ externalitiesĀ in the form of collecting and using sensitive data about their participants, suchĀ as their location.Ā However, do workers care about theseĀ externalities, and do they take them into account when deciding to accept to reject a task? In this talk, we review the conflicting literature that tried to model the economic valuation of privacy. WeĀ then focus on mobileĀ crowdsourcingĀ as a test case that simplifies some of the experimental settings involved in privacy research. To assess the value users give to their location, and to understand its relationship with information sharing, we conducted a study on a mobileĀ crowdsourcingĀ platform. We quantify how usersā valuation of location privacy is dependent on the sharing scenario. For instance, when the location is to be shared with an untrusted advertiser, the users require a premium as compensation for their information. Additionally, benefit perception and trust are found to be connected with more frequent location sharing, while perceived risks and privacy concern are associated with sharing oneās location less frequently. We then discuss how valuation-based approaches can help us better understand privacy concerns and ground theoreticalĀ notions of privacy to user behavior.
