The Wall Street Journal takes a look at privacy questions that arise from broadcasting one’s location:
As the list of programs that collect usersâ€™ location information grows, concern about privacy risks is increasing along with it.
Lorrie Cranor, an associate professor of computer science and one of the authors of the study, said people also value location-based advertising in some circumstances â€” a good thing for the companies that are building a business around precisely that. But she said many people just donâ€™t realize what a database of all the locations theyâ€™ve been at over time could mean.
â€œThere are a lot of concerns about the government being able to subpoena this information,â€ Ms. Cranor said in an interview. She also cited divorce proceedings as a possible way in which a personâ€™s location data could be used.
