Abstract

The invention discloses an application data backup recovery method of an intelligent card, an electronic device and a storage medium, wherein, the intelligent card comprises a smart card chip and an MCU module. The method comprises: if an application data backup instruction is detected, the application data in the smart card chip is saved in the MCU module according to the application data backupinstruction; if the application data backup instruction is detected, the application data in the smart card chip is stored in the MCU module. If the application data recovery instruction is detected,the application data in the MCU module is read into the smart card chip according to the application data recovery instruction. The invention provides an application data backup and restoration methodof a smart card, ELECTRONIC EQUIPMENT AND STORAGE MEDIUM, when an application data backup instruction is detected, The application data in the smart card chip is backed up to the MCU module, and whenthe data needs to be recovered, the application data in the MCU module is read into the smart card chip according to the recovery data instruction, thereby avoiding the problem that the important data loss in the application caused by deleting the application in the smart card causes the loss to the user.

Description

technical field [0001] The invention relates to the field of data backup and recovery, in particular to a smart card application data backup and recovery method, electronic equipment and a storage medium. Background technique [0002] At present, Java smart card technology provides a safe, convenient and multi-functional smart card platform, which has been widely used in financial and other industries. Developers can download and install self-developed applications, such as applets, into the Java card, and can also delete existing applications in the card. However, when the application program in the smart card is deleted, all data stored in the application program will be deleted, and if important privacy data is included, it will cause losses to the user. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a smart card application data backup recovery solution to solve the problem ...
