Social networking giant Facebook has been urged to make it easier for users to opt-out of having their data used to generate results for its new Graph Search service.
The firm took the wraps off the beta version of its new search offering earlier this week, which aims to make it easier for users to delve into their friends' interests, checked-in places and photos.
During the launch event, Facebook chief Mark Zuckerberg said the firm had gone to great lengths to ensure its new offering is "privacy aware" through the rollout of new data protection tools.
The system should be opt-out by default and if users wish to be included they should opt-in.
These include the introduction of Privacy Shortcuts, which allow users to clearly see who can view their content and contact them on the site, and a new mass untag tool.
The latter lets users disassociate themselves from multiple pictures or posts they would rather not be tagged in.
Furthermore, Zuckerberg said, as Graph Search is rolled out across the firm's user base, Facebook members will receive a prompt on the homepage telling them to review the data they have on show.
Industry feedback
Despite the introduction of these measures, concerns about how the new service may infringe on users' privacy have still been raised.
Eden Zoller, principal analyst at market watcher Ovum, said, despite Facebook's reassurances, users will need to keep their guard up.
"[Facebook] claims to have built Graph Search with privacy in mind, but Facebook has a mixed track record on this front and is in the habit of pushing privacy to the limits of what is acceptable," said Zoller.
Meanwhile, independent privacy expert, Alexander Hanff, said Facebook users should have the right to opt-in if they want their information shared via Graph Search.
"It is my belief that the system should be opt-out by default and if users wish to be included they should opt-in," Hanff told IT Pro.
"Since users never submitted their data for the purpose of Facebook creating and monitising search, it is questionable whether or not the move is compliant with the Data Protection Act," he added.
He also suggested Facebook should directly point users to the privacy settings they need to adjust to opt-out of Graph Search.
"[This should include] text overlays explaining exactly what to change and how to change it," he advised. "Anything less is completely unacceptable."
In a statement to IT Pro, Facebook said, while there is no way for users to completely opt out of Graph Search, they can easily control the amount of data featured about them.
"We think it will take time for our users to understand the full potential of Graph Search," said the statement.
"We are going to be working hard to make sure there is plenty of information available from new user education, in-product education, and...our recently announced privacy tools to help users control what they share and find the best way to use the new product," it added.
