ABSTRACT:
A system, a method, and a computer readable medium for micropayment with varying denomination are disclosed. The method utilizes a secret value, a public information, a number base parameter, a bit parameter, and merged one-way hash chains to calculate a root for providing a certificate of a transaction among a customer, a merchant and a service device. Therefore, the purpose of varying denomination for micropayment system can be achieved and the trade safety and the efficiency during the transaction process can be enhanced as well.
