Abstract
A payment management system includes a first client and an approval client. The first client provides a trade policy, generates a first hash by applying a first hash function to the trade policy, creates a first signature by asymmetrically encrypting the first hash with a first private key of a first public-private key pair, and broadcasts a first public key of the first public-private key pair. The approval client determines whether the trade policy has not been tampered with by verifying the first signature using the first public key, and determines whether at least one order comply with the trade policy after confirming that the trade policy has not been tampered with.
