ABSTRACT:
An electronic bill presentment and payment system includes multiple biller computers, a bill presentment computer, and multiple customer computers. Each biller computer stores complete bills for the customer of a corresponding biller, and the bill presentment computer stores a respective summary of each complete bill along with a hash of that complete bill which is digitally signed by the biller computer. Each particular customer computer makes a payment on a selected complete bill by generating a payment message which includes a) the hash of the selected complete bill digitally signed by the biller computer, and b) an authorization to pay a specified amount of funds on the selected complete bill, both of which are digitally signed by that particular customer computer. This payment message is stored in a closing record for use in resolving issues regarding whether or not the bill was changed after payment was authorized, and whether or not an alleged payment on the selected bill was authorized.
