Micro-payment method for divisible multimedia streaming commodities

Abstract

The invention relates to a micro-payment method for divisible multimedia streaming commodities, which comprises the following steps that a customer and a merchant respectively select the own false identities, then perform public key encryption on the own true identities, false identities and signatures, and send the encrypted public keys to a trusted third-party payment mechanism for registration; the customer initiates a purchase request to a third-party credible payment mechanism by utilizing a Hash encryption algorithm, the third-party credible payment mechanism confirms the false identity of the customer after receiving the message and then sends the purchase request of the customer to a merchant, and the merchant sends a transaction confirmation message to the third-party credible payment mechanism after receiving the message; the protocol adopts a pre-payment mechanism, and the commodity is delivered to the customer in two parts; the customer sends a payment message including a Hash value to the merchant, which indicates that the customer sends a payment bill of a to-be-purchased commodity to the merchant; and after the merchant receives the payment message and verifies the correctness of the hash value and the legality of the bill, a part of the commodity paid by the customer is sent to the customer.

Description

technical field [0001] The invention belongs to the field of information technology security, and relates to a micro-payment realization method with fair transaction on the Internet. Background technique [0002] With the development of network and information technology, micro-payment on the Internet is becoming more and more widespread, such as online novel reading, watching videos, listening to music, etc. The cost of a single purchase of such information products is generally less, but the purchase frequency is high. Therefore, this type of transaction has special requirements for the system: on the premise of satisfying certain security, it must have high processing efficiency, such as storing as little information as possible, and reducing communication overhead and computing overhead as much as possible. [0003] The classic micropayment protocol is the PayWord protocol. The protocol uses a hash chain called PayWord to represent currency. The value on PayWord is call...

AI Technical Summary

Problems solved by technology

The protocol is highly efficient, but there is no mutual identity verification between customers and merchants. Customers can use the same PayWord chain to initiate payments to different merchants, so repeated consumption by merchants cannot be prevented.

Later, Yen proposed PayFair, a micropayment protocol that prioritizes protecting the interests of users rather than merchants. Payment certificates are used to ensure the security of the protocol, but the efficiency of transactions is reduced.
