Safety information exchange device and method

Abstract

The invention provides a security information interaction device and method. Wherein, the security information interaction method includes the following steps: (A1) The security information interaction device executes an initialization operation on the security information data file, wherein the security information data file contains information related to available resources in offline An effective amount controls relevant data; (A2) The security information interaction device executes an off-line security information interaction process based on the security information interaction instruction from the security information interaction terminal and the security information data file. The security information interaction device and method disclosed in the present invention have high security information interaction efficiency and low cost.

Description

technical field [0001] The present invention relates to an information exchange device and method, and more specifically, to a security information exchange device and method. Background technique [0002] At present, with the increasingly wide application of the network and the increasingly rich types of business in different fields, the off-line mode (that is, without connecting to the data processing server through the network) through the security information interaction terminal (such as POS machine) It is becoming more and more important to complete the transfer of resources (including data information, funds, items, etc.) through the interaction of security information (that is, information with high security requirements). [0003] In the existing off-line security information interaction system and method, it is usually necessary to pre-set the offline security information interaction device (such as a financial IC card) before performing the off-line security infor...

Problems solved by technology

[0004] However, the existing off-line security information interaction systems and methods have the following problems: due to the need to use a specific device (such as a recharge terminal) with online capabilities (that is, the ability to connect to a data processing server through the network) to update the security information The value of the effective amount of available resources in the offline situation in the interaction device is set, so a large number of specific devices need to be designed and deployed; in addition, with the increasing frequency of use of the security information interaction device, users (e.g. consumers) must frequently go to the location with said specific device to pre-set the value of the effective amount of available resources before using the security information interaction device

Therefore, the efficiency of security information interaction through the existing off-line security information interaction system and method is low, and the cost of system deployment and maintenance is relatively high
