According to the Pew Research Center, American adults share a lack of confidence in the security of everyday communication channels. While the public feels the most secure using landline phones (67 percent feel at least “somewhat secure”), 81 percent feel “not very” or “not at all” secure using social media to share their private information. More than 65 percent of people report feeling insecure using chat or instant messaging services.

Only five percent of the adults surveyed had heard nothing at all about the NSA’s metadata collection and surveillance of telephone calls, emails and online communications, as leaked by Edward Snowden. News of the leaks has led, the report notes, to lower confidence in online information and communications security.
