Group purchase information transmission method and group purchase system

Abstract

The invention provides a group buying information transmission method and a group buying system. The method includes that after a group buying website receives a group buying request, a group buying website authentication request is generated, wherein the group buying website authentication request carries a website identification of the group buying website, a commodity identification of a group-bought commodity and corresponding prestored signiture data; a media exchange center generates a random number and a transaction serial number according to the group buying website authentication request; the group buying website takes an invited user number group carried in the group buying request as a corresponding group buying invited user terminal and generates a group buying notice; the group buying website combines the group buying notice, the random number and the transaction serial number into group buying information; the media exchange center checks the corresponding random number according to the transaction serial number, and verification is passed if checking is successful. As the prestored signiture data are obtained through calculation of the group buying website specific to the commodities, cost of time calculation during a private key signiture generation is reduced and work efficiency is improved.

Description

technical field [0001] The invention relates to a group buying information transmission method and a group buying system, belonging to the field of network communication. Background technique [0002] The existing group buying transaction technology provides a method for online group shopping.

The trading platform will send emails to every group buying user on the invite list according to the invite list provided by the initiator; when the group buying users of the invite party receive the email, they can The link in the website is directly connected to the invited product introduction webpage in the online trading platform, so as to place an order and other operations. Since all invited parties involved in placing an order are acquainted with the initiator, transaction disputes caused by unfamiliarity with each other can be eliminated. ...

AI Technical Summary

Problems solved by technology

[0003] There are at least the following problems in the prior art: In the above-mentioned existing group buying transaction process, the invited list and reply emails are transmitted on the network in plain text, so there is a problem of user information leakage, which brings security to the group buying process Hidden danger

In order to improve the security of group buying information transmission, it is necessary to use private key signatures. However, the process of generating private key signatures requires a large computational time overhead, thus affecting work efficiency
