Description

TECHNICAL FIELD

The present invention relates to the system, device, and method for the interaction of information, and particularly, to the system, device, and method for the interaction of security information, which are related to the transfer of resources.

BACKGROUND

Nowadays, with the increasing popularity of network applications and the emerging of various types of services in different fields, it is becoming more and more important to perform the interactions of security information (i.e., the information that requires relatively high security) related to the transfer of resources by means of security information files (e.g., the letter of credit in the financial field).

The basic operation procedure of the traditional system and method for the interaction of security information related to the transfer of resources is as follows: a first resource receiver (e.g., a buyer) initiates a request for generating a security information file (e.g., a letter of credit) associated with both a first resource (e.g., a physical resource) and a first resource transfer-out party (e.g., a seller) to a first resource transfer service provider (e.g., the buyer's account bank, and for example, a second resource may be funds) associated with the first resource receiver; the first resource transfer service provider generates and stores the security information file based on said request, and sends the security information file to a second resource transfer service provider (e.g., the seller's agreed collecting bank) associated with the first resource transfer-out party; the second resource transfer service provider receives the security information file and notifies the first resource transfer-out party; the first resource transfer-out party transmits the first resource to the first resource receiver through a third party (e.g., a freight company) and submits the physical document provided by the third party (e.g., the delivery order), which is required to take delivery of the first resource, to the second resource transfer service provider; the second resource transfer service provider checks the consistency of the content of the physical document required to take delivery of the first resource with the corresponding content in the security information file, and if there exists consistency, the second resource transfer service provider will transfer-out the second resource corresponding to the amount of the first resource to the first resource transfer-out party, and at the same time, transmits the physical document required to take delivery of the first resource to the first resource transfer service provider; the first resource transfer service provider checks the consistency of the content of the physical document required to take delivery of the first resource with the corresponding content in the security information file, and if there exists consistency, the first resource transfer service provider will transfer-out the second resource corresponding to the amount of the first resource to the second resource transfer service provider; the first resource transfer service provider notifies the first resource receiver that the physical document required to take delivery of the first resource have been received; the first resource receiver transfer-in the second resource corresponding to the amount of the first resource to the first resource transfer service provider, to obtain the physical document required to take delivery of the first resource, and then obtains the first resource based on the physical document required to take delivery of the first resource.

However, the conventional system and method for the interaction of security information related to the transfer of resources have the following drawbacks: since the security information file and the document required to take delivery of the first resource are both physical files, more manual processing steps will be involved, and thus it will be difficult to monitor the steps of processing and transferring such physical files, and the physical files can be easily tampered and forged, moreover, there is a lack of a mechanism for verifying the authenticity of the security information file and the document required to take delivery of the first resource, therefore, there exists high risk of security, furthermore, since the transfer of the second resource is separated from the transfer of the first resource (i.e., the first resource receiver has performed the transfer of the second resource before verifying the authenticity of the first resource), the quality and reliability of the transfer of the first resource through the interaction of the security information can not be guaranteed (for example, the first resource may not be consistent with the expected).

Therefore, there exists a need for the system, device and method for interaction of the security information related to the transfer of resources with high security and reliability.
