Title: Scalable auditability of monitoring process using public ledgers

Abstract

Secure auditability of monitoring processing using public ledgers that are particularly useful for monitoring surveillance orders, whereby an overseeing enforcer (“E”) checks if law enforcement agencies and companies are respectively over-requesting or over-sharing user data beyond what is permitted by the surveillance order, in a privacy-preserving way, such that E does not know the real identities of the users being surveilled, nor does E get to read the users' unencrypted data. Embodiments of the present invention also have inbuilt checks and balances to require unsealing of surveillance orders at the appropriate times, thus enabling accounting of the surveillance operation to verify that lawful procedures were followed, protecting users from government overreach, and helping law enforcement agencies and companies demonstrate that they followed the rule of law.
