Method and system for acquiring application data

Abstract

The invention discloses a method and a system for acquiring application data in order to solve the problem of high maintenance cost when a merchandiser distinguishes application data, such as electronThe invention discloses a method and a system for acquiring application data in order to solve the problem of high maintenance cost when a merchandiser distinguishes application data, such as electronic ticket information, and the like. The method comprises the steps: a square code is provided by a server according to application data in a downloading request; a secret key KB2 is generated by a seic ticket information, and the like. The method comprises the steps: a square code is provided by a server according to application data in a downloading request; a secret key KB2 is generated by a serial number of a smart card determined by user identification; the server downloads a first cryptograph obtained by using the generated secret key KB2 to encrypt the application data to the smart cardrial number of a smart card determined by user identification; the server downloads a first cryptograph obtained by using the generated secret key KB2 to encrypt the application data to the smart card; the square code is provided by a terminal identifying device according to the prestored application data; and the secret key KB2 is generated by the serial number of the smart card. According to the; the square code is provided by a terminal identifying device according to the prestored application data; and the secret key KB2 is generated by the serial number of the smart card. According to the secret key KB2, the first cryptograph obtained from the smart card is decrypted to obtain the application data. Because the terminal identifying device uses the secret key KB2 which is correlated witsecret key KB2, the first cryptograph obtained from the smart card is decrypted to obtain the application data. Because the terminal identifying device uses the secret key KB2 which is correlated with the serial number of the smart card to finally obtain the application data, the use uniqueness of an electronic ticket can be distinguished without depending on a background database system, and theh the serial number of the smart card to finally obtain the application data, the use uniqueness of an electronic ticket can be distinguished without depending on a background database system, and the maintenance cost of the ticket identification by the merchandiser is reduced.maintenance cost of the ticket identification by the merchandiser is reduced.

Description

technical field [0001] The invention belongs to the field of data processing, in particular to a method and system for acquiring application data. Background technique [0002] With the continuous extension of the development of the Internet, e-commerce has penetrated into all areas of our daily life, and more and more new Internet products have been recognized by consumers. Merchants who provide commodities during commodity transactions will send application data related to commodities to users. For example, electronic ticketing information is the application data in electronic ticketing applications. Electronic ticketing is a new network product based on this point. It is different from Compared with the previous traditional ticketing model, it has the characteristics of low ticket sales cost, easy organization of sales, and convenience for customers, and truly realizes the one-stop service of online ticket purchase. Users can get an electronic ticket as long as they pay ...
