'Canary Watch' legally reveals when sites get national security requests

10 Feb 2015 • engadget.com

Like the birds that show a mine is safe by not being dead, the site tracks statements by websites like Pinterest saying they haven’t received national security requests. If such “warrant canaries” suddenly disappear, Canary Watch will flag that fact, revealing that the site actually has received a request without breaking any laws.

Great idea for a service.
