User privacy attitudes regarding proximity sensing

User attitudes on privacy with respect to location data has been extensively studied. However, user attitudes of privacy in relation to proximity sensing is still lacking. We present the results from a survey conducted on users of a proximity sensing application we developed and diffused by handing out phones with the proximity sensing application pre-installed, with 31 respondents. The results compare this type of application to location sensing in general, as well as positions our respondents in relation to previous studies in terms of general privacy policies. Four results stand out in particular: One, our respondents are more aware of and care about privacy policies than in previous studies. Two, trust is reported as being based more on the specific data access asked for, than EULA or similar text based policies. Third, the respondents are willing to allowing having proximity data about them sensed, as long as they are in control of who can sense it. Finally, our results indicate that there is no perceived difference in sensitivity between location and proximity sensing.
