Some websites that are dating maybe not eliminate GPS information from photos, CU-Boulder pupils find

Although the most of dating internet sites do good work of handling the privacy of the users, a course research study during the University of Colorado Boulder’s Leeds School of Business unearthed that 21 of 90 dating sites the course examined failed to properly remove location data from photos uploaded by their users.

Due to individuals using more photographs with digital cameras and cellular phones containing worldwide Positioning System chips, some dating website profile photos contain GPS coordinates showing where an image was taken, said Associate Professor Kai Larsen, whom taught the course on Privacy when you look at the Age of Twitter. Whenever such info is perhaps not removed by the dating internet site, commonly available tools could be used to identify the positioning of a person’s residence or any other areas frequented by the individual.

This space in privacy protection actually leaves ladies users specially susceptible to online predators, the CU-Boulder pupil researchers stated. Users of dating websites share an array of personal details but generally speaking will maybe not share their details or genuine names unless a stronger relationship develops through numerous online and interactions that are offline.

The biggest online dating sites, such as and, had been found to get rid of location metadata from account pictures. But 23 % associated with the 90 web sites had been found to go out of metadata connected to the profile picture. Many of these specialized internet dating sites were considering such characteristics as age, disability, pastime or faith.

Twelve of this 21 sites had been run by an individual Canadian business, In line with the SuccessfulMatch internet site, the business runs 24 dating sites from the exact same platform, 12 of that have been perhaps maybe not examined within the scientific study.

“While we were very happy to see such a higher degree of accountable behavior by internet dating businesses, a predator that is online need no one or more web site to work irresponsibly,” Larsen stated. “The undeniable fact that we discovered significantly more than 20 internet sites that don’t very carefully keep individual privacy is cause for concern, for the reason that specific users are left to keep up their very own privacy by carefully confirming that any uploaded picture doesn’t include GPS coordinates.”

Metadata is “a collection of data that defines and gives details about other information,” Larsen said. Such information that may be produced from online pictures includes camera type, date of capture, whether or not the photo is modified and GPS coordinates of where in actuality the photo ended up being taken.

Dating websites are able to “scrub” or expel such metadata from their user photos & most do because misuse for the information could compromise the security of these users, Larsen stated.

The study way of the research included the creation of individual profiles of two people, the information that is personal of which had been fabricated with the exception of the photos, which included location information as well as other metadata, Larsen stated. The photo uploaded by one user then was installed because of the other individual while the presence regarding the location information confirmed.

The internet sites discovered not to eliminate location metadata were contacted on Dec. 29, 2011, plus the Leeds School group has since caused some of those dating site companies to make certain that location metadata is eliminated prior to the study outcomes had been publicly established.

“It was clear that some organizations would not find out about this matter,” Larsen stated. “The feedback ranged from appreciative to reluctantly getting rid of the metadata to no reaction.” A number of the firms instantly stated that they certainly were action that is taking resolve the matter, including SuccessfulMatch as well as 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 indeed today that is important a lot of companies cope with extremely personal information,” Larsen stated. “Company choices on how to cope with information privacy make a difference their valuation.”

The information and knowledge management class had been provided jointly because of the Leeds School’s Division of Management and Center for Education on Social Responsibility.
