## Abstract

Provided are a method and apparatus for managing a terminal. The method of managing a terminal may include obtaining a variable identification value of a first user terminal, generating a first user terminal group including the first user terminal based on an identification value of a first user, and mapping variable identification values of one or more user terminals included in the first user terminal group to the identification value of the first user and mapping user information obtained from an external device to the identification value of the first user.

## Claims

### Claim 1

A method, performed by a computing apparatus, of managing a terminal, the method comprising:
obtaining a variable identification value of a first user terminal;
generating a first user terminal group comprising the first user terminal based on an identification value of a first user; and
mapping variable identification values of one or more user terminals comprised in the first user terminal group to the identification value of the first user and mapping user information obtained from an external device to the identification value of the first user.

### Claim 2 (depends on 1)

The method of claim 1, further comprising
transmitting designated content to the one or more user terminals comprised in the first user terminal group,
wherein the designated content is determined based on the identification value of the first user.

### Claim 3 (depends on 2)

The method of claim 2, further comprising:
obtaining a variable identification value of a second user terminal;
generating a second user terminal group comprising the second user terminal based on an identification value of a second user; and
when the identification value of the first user and the identification value of the second user satisfy a preset condition, transmitting content determined based on the identification value of the first user to one or more user terminals comprised in the second user terminal group.

### Claim 4 (depends on 2)

The method of claim 2, wherein
the variable identification value of the first user terminal is a unique value of the first user terminal that is changeable by a user,
log data of a first application executed in the first user terminal corresponds to the variable identification value of the first user terminal, and
the designated content is executed in at least one of the first application and a second application of the first user terminal.

### Claim 5 (depends on 2)

The method of claim 2, wherein
the first user terminal group further comprises a third user terminal, and
the designated content transmitted to the third user terminal is determined based on log data of a first application executed in the first user terminal.

### Claim 6

An apparatus for managing a terminal, the apparatus comprising
a processor,
wherein the processor is configured to obtain a variable identification value of a first user terminal, generate a first user terminal group comprising the first user terminal based on an identification value of a first user, map variable identification values of one or more user terminals comprised in the first user terminal group to the identification value of the first user, map user account information obtained from an external device to the identification value of the first user, and transmit designated content to the one or more user terminals comprised in the first user terminal group, wherein the designated content is determined based on the identification value of the first user.
