Problems solved by technology

When high-level affairs operate on more than two records on the smart card, due to power outages, system crashes, program errors, and malicious card draws, etc., the data modification of the smart card is interrupted, resulting in incomplete data on the smart card, such as only One piece of data has been modified, but another piece of data has not yet been modified

Embodiment

[0040] The present invention further explains the implementation of the method by taking recharging a multi-indicator refueling smart card as an example. The card data structure of the multi-indicator refueling smart card is as follows:

[0041] Record number Indicator type Indicator margin

[0042] 1 index 1 1000.12

[0043] 2 Index 2 2000.34

[0044] Assume that a card operation needs to update the index balance of the two records of index 1 and index 2 on the card, and at the same time deduct the balance of index 1 and index 2 in the index table in the database. Data flow diagram such as image 3 shown.

[0045] When the smart card is operated, a certain record is operated as an independent transaction. When high-level affairs operate on more than two records on the smart card, due to power outages, system crashes, program errors, and malicious card draws, etc., the data modification of the smart card is interrupted, resulting in incomplet...

Abstract

The invention discloses a safe card signing method for an intelligent card database application system, which comprises the following steps: (1) reading intelligent card information and detecting a written mark in an intelligent card; (2) storing intelligent card original data into a database; (3) opening up a database transaction; (4) updating the database; (5) setting a written mark in the intelligent card; (6) updating the intelligent card; (7) changing an intelligent card original data state mark stored in the database into a processed mark; (8) submitting the database transaction; and (9) clearing the written mark in the intelligent card, and accomplishing the singing of the intelligent card. A database transaction processing mechanism is used to ensure that the processing state of the intelligent card original data stored in the database is consistent with the submission state of the transaction processing data in the database, and thus, intelligent cards storing dirty data are prevented from being used.

Description

technical field [0001] The invention relates to a smart card database application system, in particular to a safe card signing method of the smart card database application system. Background technique [0002] In the development of database application system including smart card application, there is a synchronous operation of database transaction and smart card data update, and only relying on the transaction processing mechanism provided by the database management system cannot realize the consistency of database data and smart card data in the system. When the smart card is operated, a certain record is operated as an independent transaction. When high-level affairs operate on more than two records on the smart card, due to power outages, system crashes, program errors, and malicious card draws, etc., the data modification of the smart card is interrupted, resulting in incomplete data on the smart card, such as only One piece of data has been modified, but another piec...
