Method, equipment and intelligent card for back-upping and recovery of intelligent card application data

Abstract

The invention provides a method, equipment and intelligent card for back-upping and recovery of intelligent card application data and aims to solve the problem in the prior art that data back-upping operations and data recovery operations are complicated during back-upping of data of a to-be-updated application on the intelligent card and during data recovery of the updated application based on the backup data. The method provided by the invention comprises the steps that after receiving an application update request sent by a terminal, the intelligent card backups the application data of an application corresponding to the application update request to a backup pool; and after completion of application update operations, the intelligent card recovers the application data of the updated application according to the application data in the backup pool. According to the embodiment of the invention, the back-upping and recovery operations to the application data carried out by an application publisher or a remote reliable service platform are avoided, and complexity in the back-upping and recovery operations of the application data is reduced, so that the efficiency for the data back-upping and recovery is further increased.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and smart card for backing up and restoring application data of a smart card. Background technique [0002] With the continuous promotion of smart cards and the continuous cultivation of users' habit of using smart cards for consumption, the technology of smart card platforms supporting multiple applications has emerged as the times require. Users can use the smart card for daily consumption settlement, and can also download and install the application provided by the merchant on the smart card, earn points or get discounts when consuming, so as to realize the multi-purpose function of one card. Users can directly download the application to the smart card through the remote trusted service platform. At the same time, as the application is continuously updated, when the user updates the application on the smart card, he needs to delete the application that...
