Vertification and payment method, device and operation method of its system and its component

Abstract

Service procedures and / or message formats such as encryption and attachment of a digital signature are properly used according to an available amount of money defined in a certificate of service, network environments such as intensity of security, transmission band and locations of communication paths and operation policy, whereby the system enables to shorten service providing time, to adjust the intensity of security and to reduce the amount of information transmitted through the information network. It is preferable to encrypt a part of the information or to attach a digital signature to the part of the information, instead of encrypting all information or attaching the digital signature to all information. Consequently, encryption of only the important portion of the information can be available. It is further preferable to store a part of the information into a storage device, instead of containing a part of the information into the body of the message to be sent, and to contain information of the location in the storage device into the body of the message to be sent. As a result, the amount of information transmitted through the information network can be reduced. This technique is particularly effective for an attachment of low usage information.
