Problems solved by technology

[0005] In this way, once the application background environment of the smart card database changes, or the function needs to be expanded in the same application background environment, such as making the smart card used in the financial industry support medical applications, the database card needs to be redesigned The processing method of the smart card needs to re-download the underlying operating system of the smart card, which not only increases the cost, but also is very inflexible and inconvenient
[0006] Therefore, the existing method for processing the smart card database is limited by the specific application of the database card, lacks the versatility of use, and is not convenient for the application and promotion of the database card

Embodiment 1

[0087] Embodiment 1: In this embodiment, the access terminal is a PC terminal, and a data communication protocol is agreed between the access terminal and the smart card. The system for processing the smart card database is as follows: image 3 As shown, it includes a PC terminal 100 and a smart card 200, wherein the PC terminal includes an application unit 110 and a PC terminal database (DB) operation interface 120, while the smart card includes a DB management platform 210 and a smart card terminal DB operation interface 220. The communication between the PC end and the smart card is completed in accordance with the APDU of the ISO7816-4 specification. The basic format of the APDU operation command is shown in Table 1, and the basic format of the APDU response command is shown in Table 3. Wherein, the attribute information of the APDU operation instruction or the APDU response instruction is represented by a hexadecimal number. Then under this system architecture, the process...

Abstract

The invention discloses a method, a system and a device for processing a smart card database, which are used for improving universality of a database card and expanding the application field of the database card. The method comprises the following steps that: an access terminal encapsulates information of each parameter in a database operation request into a corresponding application protocol data unit operation command according to an agreed data communication protocol; the access terminal transmits the application protocol data unit operation command to the smart card to enable the smart cart to analyze the application protocol data unit operation command according to the agreed data communication protocol, acquire command information of operating the database, process the corresponding database according to the command information, encapsulate the processed response data into an application protocol data unit response command and send the application protocol data unit response command back to the access terminal according to the agreed data communication protocol; and the access terminal analyzes the received application protocol data unit response command according to the agreed data communication protocol to acquire a processed result.

Description

technical field [0001] The invention relates to the technical field of smart cards, in particular to a method, system and device for processing smart card databases. Background technique [0002] With the development of integrated circuit (IC, Integrated Circuit) card technology, IC cards are more and more widely used in telecommunications, finance, government, transportation and other fields. The capacity of several GBytes. The data content attributes in the card are also becoming more and more abundant. In order to effectively manage the data on the IC card, a data management platform is introduced into the software platform of the smart card, so that the limited resources on the card can be used to manage various data applications on the card flexibly and efficiently. This kind of smart card introduced into the data management platform is also called database card. [0003] When the database card is applied, it is necessary to process the database in the card from the ...
