The Pew Research Center did an extensive survey on public perceptions of privacy and security in the so called post-Snowden era. There are a lot of interesting takeaways in the report. Here are just a few:

Perhaps most striking is Americans’ lack of confidence that they have control over their personal information. That pervasive concern applies to everyday communications channels and to the collectors of their information—both in the government and in corporations.

And:

Across the board, there is a universal lack of confidence among adults in the security of everyday communications channels—particularly when it comes to the use of online tools. Across six different methods of mediated communication, there is not one mode through which a majority of the American public feels “very secure” when sharing private information with another trusted person or organization.

And:

Most say they want to do more to protect their privacy, but many believe it is not possible to be anonymous online.

And:

Social security numbers are universally considered to be the most sensitive piece of personal information, while media tastes and purchasing habits are among the least sensitive categories of data.

Lots to think about here.
