9. A non-transitory computer-readable recording medium which records a program for executing a method for managing a secure element (SE) in a user terminal, the method comprising:

in response to the user terminal receiving a backup command on secure information stored in the SE from a user of the user terminal, identifying, by the user terminal, the secure information stored in the SE;

sending, by the user terminal, a command to request to set suspension of use of a means of payment included in the secure information stored in the SE to a secure server;

generating, by the user terminal, backup data using at least part of the identified secure information after the command to request to set the suspension of use of the means of payment is sent to the secure server;

transmitting, by the user terminal, the backup data from the SE to the secure server through a secure channel set between the secure server and the SE and storing the backup data;

in response to an update of the SE being completed and detected by the user terminal, transmitting, by the user terminal, a restoration command on the secure information to the secure server; and

in response to the restoration command on the secure information being transmitted by the user terminal, restoring the backup data of the secure server to the SE or another SE,

wherein the restoring the backup data comprises sending, by the user terminal, a command to request to set use of the means of payment included in the secure information stored in the SE based on the backup data to the secure server.

10. A system for managing a secure element (SE) in a user terminal, comprising:

a processor; and

a memory storing instructions executable by the processor,

wherein the processor is configured to:

in response to the user terminal receiving a backup command on secure information stored in the SE from a user of the user terminal, identify, by the user terminal, the secure information stored in the SE;

send, by the user terminal, a command to request to set suspension of use of a means of payment included in the secure information stored in the SE to a secure server;

generate, by the user terminal, backup data using at least part of the identified secure information after the command to request to set the suspension of use of the means of payment is sent to the secure server;

transmit, by the user terminal, the backup data from the SE to the secure server through a secure channel set between the secure server and the SE to store the backup data;

in response to an update of the SE being completed and detected by the user terminal, transmit, by the user terminal, a restoration command on the secure information to the secure server;

in response to the restoration command on the secure information being transmitted by the user terminal, restore the backup data of the secure server to the SE or another SE; and

send, by the user terminal, a command to request to set use of the means of payment included in the secure information stored in the SE based on the backup data to the secure server.
