The ProofMark software solution is a broadly applicable system that operates on a computer, server, network, system, or infrastructure. This system utilizes public-key cryptography to create an irrefutable record of the time-existence and exact composition of any digital data. This document, the ProofMark System Concepts, Architecture, and Planning Guide, provides you with a broad technical overview of the ProofMark system.
