A letter signed by some of the most prolific US-based technology companies such as Apple, Facebook and Google has been sent to the Obama administration and Congress today asking for greater transparency over national security-related data requests. The alliance, rumored yesterday to be readying the document, is now urging the US government to give them permission to publish regular reports that would indicate at least some of the type and quantity of information being collected. This would include the number of requests for information – related to their users – submitted under specific legislation such as Section 215 of the USA Patriot Act and Section 702 of the FISA Amendments Act. It would also cover the number of individuals, accounts and devices that were requested by each authority, as well as the total amount of requests for data related to user messaging or calls.
