Data transaction processing method and apparatus

Abstract

The invention discloses a data transaction processing method and a device thereof, including that after a service end receives a transaction request submitted by a client end through the internet, the service end sends data including identification data and transaction feed-back data, which need to be identified and fed back to a movable terminal by the client end; after the movable terminal receives data needing to be identified and fed back, the identification data are verified according to identity key in the movable terminal user identity recognition module card, which is offered in advance, after the verification is passed, the feed-back data is acquired after processing according to transaction feed-back data content; after a user identity recognition module card operating system makes a signature on the feed-back data, the feed-back data is fed back to the service end by the client end; the signature of the feed-back data is verified according to a signature key in the service end, which is offered by the movable terminal user in advance, after the verification is passed, the feed-back data is processed based on the feed-back data content. By utilizing the invention, the identity certification and the transaction certification problems in the network transaction are resolved, and the safety of the client end in the network environment is ensured.

Description

technical field

[0001] The present invention relates to the field of data security, in particular to a data transaction processing method, device, SIM (Subscriber Identity Module, Subscriber Identity Module) card and system. Background technique

[0002] With the vigorous development of various online transactions such as online banks and online shopping malls, the security of transactions has become an increasingly important issue. In any network transaction environment, security issues mainly exist in the server, network and client. The security of the server is the responsibility of the service provider, which can be guaranteed by means of physical control, security management, and network security software and equipment; the security of data transmission on the network can be solved by data encryption and decryption technology based on cryptography methods, such as extensive The SSL (Secure Socket Layer) protocol is adopted; the client user in the network environment ob...
