Whenever information that is such maybe perhaps not removed by the dating site, commonly available tools could be used to identify the area of a person’s residence or other places frequented by the individual.

The study approach to the research included the development of user profiles of two individuals, the information that is personal of had been fabricated with the exception of the pictures, which included location information as well as other metadata, Larsen stated. The picture uploaded by one individual then was installed because of one other individual plus the presence of this location information confirmed.

The web sites found to not eliminate location metadata were contacted on Dec. 29, 2011, additionally the Leeds class team has since caused some of those dating companies that are website make sure that location metadata is eliminated prior to the study outcomes had been publicly established.

“It was clear that some businesses would not learn about this problem,” Larsen stated. “The feedback ranged from appreciative to reluctantly removing the metadata to no reaction.” Many of the businesses straight away stated that these were following through to resolve the matter, including SuccessfulMatch therefore the businesses behind CatholicSingles, DeafSinglesMeet and MeetingMillionaires.

A business that tracks consumer that is online, Experian Hitwise, recently detailed significantly more than 1,100 sites with its “lifestyle dating” category.

“Technology is really so today that is important a lot of companies cope with extremely personal data,” Larsen stated. “Company choices on how to cope with information privacy make a difference their valuation.”
