Facebook's continued changes in automatically shared information are becoming a concern on a personal level, and on a larger scale.
New Facebook features, including the Timeline feature, automatically offer personal information to other users. Tracking cookies are used to monitor activity and correlate user interests.
Two congressmen and ten consumer and privacy groups have asked the Federal Trade Commission to investigate these new techniques, according to an ABC report.
Facebook representatives maintain their dedication to user security. However, several Internet experts are concerned that users will be subject to scams and information theft.
"This will make it a lot easier to obtain valuable information about an individual," Caitlin Cosoi, an researcher at anti-virus firm Bitdefender, told ABC.
Tracking occurs even after users have logged off the website, according to an MSNBC report. Any website with a "like button" will send information back to Facebook.
A Facebook statement last Thursday claimed that there was "no security or privacy breach," according to the MSNBC report.
