In the prior art, after a user replaces an SIM card, application data in the old SIM card will be lost, and if the user wants to continue to use the original application, the operation flow is tedious. For example, in the wallet application on the SIM card, the wallet account balance on the old SIM card needs to be brought up, then the account-canceling operation is performed, then the account opening is performed on the wallet application on the new SIM card, and then the recharging operation is performed, so that the wallet application can be continuously used, which is complicated in operation and poor in user experience. In order to solve the technical problem, the embodiment of the invention realizes the cloud migration of the specified AID application data on the SIM card by backing up the Applet based on the SIM card access technology and the SIM card data short message technology.
As shown in fig. 1, an embodiment of the present invention provides a SIM card based application data backup/restore system, which includes a TSM platform 100, a client 200, and a SIM card 300.
The SIM card 300 includes COS, backup Applets and Applets, and the backup Applets and the Applets may perform data interaction through a shared interface/private API; if the backup Applet adopts a Java application form, the backup Applet and Applets realize data interaction through a standard shared interface technology; if the backup Applet adopts a Native application form, the backup Applet and the Applets realize data interaction through a private API (application programming interface) technology, and both the two modes have a safety protection mechanism.
The client 200 communicates with the SIM card 300 based on a mobile phone SIM card access technology, and obtains data to be backed up of a specific AID application (i.e., applets, application to be backed up) through a backup Applet, or writes data to be restored of the specific AID application (i.e., applets, application to be restored) through the backup Applet; the client 200 further communicates with the TSM platform 100 to upload data to be backed up of a specific AID application acquired from the backup Applet on the SIM card 300, or acquire data to be restored of the specific AID application from the TSM platform 100.
The TSM platform 100 may directly communicate with the SIM card 300 through SMS or BIP and other communication technologies, or communicate with the SIM card 300 by using the client 200, so as to obtain the data to be backed up of the specified AID application through a backup Applet, or write the data to be restored of the specified AID application through the backup Applet; data protection is carried out among the TSM platform 100, the client 200 and the SIM card 300 by adopting a point-to-point secure encryption communication technology.
As shown in fig. 2 and fig. 3, in some embodiments of the present invention, a SIM card-based application data backup method is provided, where the method is implemented by the TSM platform 100 communicating with the SIM card 300 through SMS or BIP technologies, and the method includes the following steps:
step S100: in response to a data backup request message sent by the TSM platform 100, the backup Applet obtains data to be backed up of the application to be backed up, and saves the data to be backed up;
step S200: the backup Applet generates a data backup response message according to the data to be backed up and sends the data backup response message to the TSM platform 100;
step S300: the TSM platform 100 acquires and stores the data to be backed up according to the data backup response message, and sends a data backup success message to the backup Applet;
step S400: and responding to the message of successful data backup, the backup Applet removes the data to be backed up and locks the application to be backed up.
Specifically, as shown in fig. 3, the TSM platform 100 issues a data backup request message of an application to be backed up, which specifies an AID, to a backup Applet through an SMS (or a technique such as BIP, the same applies below); the backup Applet calls a shared interface getBackupdata () for the application to be backed up of the specified AID (or calls a private API, which is determined by the form of the backup Applet, the same applies below) to acquire the data to be backed up, and the data to be backed up can be called for many times according to the size of the data volume to be backed up; and after the backup Applet acquires all the data to be backed up, the data to be backed up is stored.
The backup Applet monitors whether the data to be backed up need to be uploaded to the TSM platform 100 through state event polling, and if not, the backup Applet continues polling monitoring; if so, assembling a data backup response message (ciphertext + MAC value) according to the data to be backed up. The backup Applet sends a data backup response message to the TSM platform 100, and may need to send multiple pieces according to the size of the data volume.
After receiving the data backup response message uploaded by the backup Applet, the TSM platform 100 checks the MAC value, decrypts after checking no error, obtains and stores the data to be backed up, and issues a data backup success message to the backup Applet.
And after receiving the data backup success message, the backup Applet clears the data to be backed up, calls a shared interface blockApp () to lock the application to be backed up, and prohibits the transaction after the data backup so as to ensure the data consistency of the TSM platform 100 and the SIM card 300.
The application data backup method based on the SIM card has the advantages of convenient operation, high safety and universality, and can conveniently backup the application data on the SIM card 300, so that the application data on the old SIM card can not be lost when a user replaces the SIM card, and the subsequent re-downloading is facilitated.
Corresponding to the above method for backing up application data based on an SIM card, as shown in fig. 4 and 5, an embodiment of the present invention further provides a method for recovering application data based on an SIM card, where the method includes the following steps:
step S100a: responding to a data recovery request message sent by the TSM platform 100, and obtaining and storing data to be recovered of the application to be recovered by the backup Applet;
step S200a: the backup Applet sends the data to be recovered to the application to be recovered so that the application to be recovered executes data recovery operation;
step S300a: after the data recovery operation is completed, the application to be recovered sends an execution result response message to the backup Applet;
step S400a: responding to the execution result response message, and removing the data to be recovered by the backup Applet;
step S500a: the backup Applet activates the application to be restored and sends a data restoration response message to the TSM platform 100.
Specifically, as shown in fig. 5, the TSM platform 100 issues a data recovery request packet specifying an AID (application to be recovered) to the backup Applet, and multiple packets may be sent according to the size of the data volume; after the backup Applet receives all the data, the data integrity of the data recovery request message is checked, and after the data integrity is checked, the data to be recovered is obtained through decryption and stored.
Then, the backup Applet calls a shared interface restorarebakupdata () to the application to be restored of the specified AID to send data to be restored, and the backup Applet can be called for multiple times according to the size of the data volume; after receiving all the data to be recovered, the application to be recovered firstly verifies the integrity of the data to be recovered, decrypts the data after the verification is passed, and then executes data recovery operation.
After the data recovery operation is completed, the application to be recovered sends an execution result response message to the backup Applet, after the backup Applet receives the execution result response message, the backup Applet empties the data to be recovered, and calls a shared interface activeApp () for the application to be recovered of the specified AID to activate the application to be recovered (after the activation is successful, the application to be recovered can be normally used); finally, the backup Applet sends a data recovery response message to the TSM platform 100.
According to the application data recovery method based on the SIM card, which is disclosed by the embodiment of the invention, by matching with the application data backup method based on the SIM card, the application data on the SIM card can be conveniently migrated, the application data on the old SIM card is migrated to the new SIM card, the operation is convenient, the safety and the universality are higher, and the user experience degree is improved.
On the other hand, as shown in fig. 1, in addition to the TSM platform 100 directly communicating with the SIM card 300 through SMS or BIP technology to implement migration of application data, the TSM platform 100, the client 200, and the SIM card 300 may cooperate with each other to implement migration of application data through a machine-card channel between the client 200 and the SIM card 300.
For this reason, as shown in fig. 6 and fig. 7, in the embodiment of the present invention, another SIM card-based application data backup method is further provided, where the method includes the following steps:
step S100b: in response to a selection command and a backup data obtaining command sent by the client 200, the backup Applet obtains and saves the data to be backed up of the application to be backed up;
step S200b: the backup Applet generates a data backup response message according to the data to be backed up and sends the data backup response message to the client 200;
step S300b: the client 200 sends the data backup response message to the TSM platform 100, the TSM platform 100 acquires and stores the data to be backed up according to the data backup response message, and sends a data backup success message to the client 200;
step S400b: in response to the data backup success message, the client 200 sends a locking command to the backup Applet;
step S500b: and responding to the locking command, the backup Applet clears the data to be backed up and locks the application to be backed up.
Specifically, as shown in fig. 7, the client 200 sends a selection command and a GET BACKUP DATA command GET BACKUP DATA to the BACKUP Applet; the backup Applet calls a shared interface getBackupdata () to the application to be backed up of the specified AID to acquire data to be backed up, and the shared interface getBackupdata () may be called for many times according to the size of the data to be backed up.
After the BACKUP Applet acquires all the DATA to be backed up, the DATA to be backed up is stored, a DATA BACKUP response message is assembled to serve as response DATA to a GET BACKUP DATA command, and the assembled DATA BACKUP response message is sent to the client 200; if the DATA to be backed up cannot be completely sent by a RESPONSE command, the RESPONSE status word of the GET BACKUP DATA command is 0x91XX, and the client 200 obtains the remaining RESPONSE DATA with the length of 0XX by the GET RESPONSE DATA again until the RESPONSE status word is 0x9000, which indicates that all RESPONSEs of the DATA to be backed up are finished.
After the client 200 acquires all the data to be backed up, the data is uploaded to the TSM platform 100, the TSM platform 100 firstly verifies the integrity of the data, decrypts and stores the data after the verification is passed, and transmits a data backup success message to the client 200; after receiving the successful data backup message of the TSM platform 100, the client 200 sends a lock command BLOCK APP to the backup Applet; after receiving the BLOCK APP command of the client 200, the backup Applet removes the data to be backed up, calls a shared interface blockApp () to the application to be backed up of the specified AID to lock the application, and prohibits the transaction after data backup so as to ensure the data consistency of the TSM platform 100 and the SIM card 300.
The application data backup method based on the SIM card has the advantages of convenient operation, high safety and universality, and can conveniently backup the application data on the SIM card 300, so that the application data on the old SIM card can not be lost when a user replaces the SIM card, and the subsequent re-downloading is facilitated.
Corresponding to the above method for backing up application data based on an SIM card, as shown in fig. 8 and 9, an embodiment of the present invention further provides another method for recovering application data based on an SIM card, where the method includes the following steps:
step S100c: the client 200 acquires data to be recovered of the application to be recovered from the TSM platform 100;
step S200c: the client 200 sends a selection command and a data recovery command to the backup Applet so that the backup Applet can acquire and store data to be recovered;
step S300c: the backup Applet sends the data to be recovered to the application to be recovered so that the application to be recovered executes data recovery operation;
step S400c: after the data recovery operation is completed, the application to be recovered sends an execution result response message to the backup Applet;
step S500c: in response to the execution result response message, the backup Applet clears the data to be restored, and sends a data restoration response message to the client 200;
step S600c: in response to the data recovery response packet, the client 200 sends an activation command to the backup Applet, so that the backup Applet activates the application to be recovered, and sends an activation response packet to the client 200.
Specifically, as shown in fig. 9, the client 200 acquires data to be restored of an application to be restored specifying an AID from the TSM platform 100; subsequently, the client 200 sends a selection command and a DATA recovery command RESTORE DATA to the BACKUP Applet, and may send the selection command and the DATA recovery command RESTORE DATA for multiple times according to the size of the DATA volume; after the to-be-backed Applet receives all the to-be-restored data, the to-be-backed Applet calls a shared interface restoraBackuData () to the to-be-restored application of the specified AID to send the to-be-restored data, and the to-be-restored data can be called for many times according to the size of the data.
After receiving all the data to be recovered, the application to be recovered firstly verifies the integrity of the data to be recovered, decrypts the data after passing the verification, and executes data recovery operation; after the data recovery operation is completed, the application to be recovered sends an execution result response message to the backup Applet; after receiving the execution result response message, the backup Applet clears the data to be restored, and sends the data restoration response message to the client 200. The client sends an ACTIVE command ACTIVE APP to a backup Applet, and the backup Applet calls a shared interface activeApp () to activate the application to be recovered of the specified AID (after the activation is successful, the application to be recovered can be normally used); and finally, the backup Applet sends the activation response message to the client.
According to the application data recovery method based on the SIM card, which is disclosed by the embodiment of the invention, by matching with the application data backup method based on the SIM card, the application data on the SIM card can be conveniently migrated, the application data on the old SIM card is migrated to the new SIM card, the operation is convenient and fast, the safety and the universality are higher, and the user experience is improved.
On the other hand, in some embodiments of the present invention, a SIM card based application data backup system is further proposed, where the system includes the TSM platform 100, the client 200, and the SIM card 300, and the system may be used to implement the above SIM card based application data backup method, so as to implement backup of application data.

According to the application data backup/recovery system based on the SIM card, the technical difficulty that the original application data of the old card is lost and cannot be used continuously when a user changes the SIM card is solved, the method is simple and convenient to operate and high in convenience, and the user experience degree is improved. In the SIM card access technology related in the embodiment of the present invention, due to the difference of the Mobile phone operating systems, for the Android system, the client 200 may use Open Mobile, OMA, telephonyManager, or other libraries to access the SIM card 300; for the iOS system, the Bluetooth SIM card technology can be adopted for replacing the iOS system, and the effect of the SIM card access technology can also be achieved.
