## Abstract

Provided is a device control system including: a device, which has a device ID for identifying the device, and is configured to write a user ID for identifying a user in a memory based on an instruction to register the user ID; and a server configured to transmit a message containing the user ID and a command to the device having the device ID. The device is configured to: receive the message, and compare the user ID contained in the message and the written user ID; and determine whether the command contained in the message is executable in accordance with a result of the comparison.

## Claims

### Claim 1

A device control system, comprising:
a device, which has a device ID for identifying the device, and is configured to write a user ID for identifying a user in a memory based on an instruction to register the user ID; and
a server configured to transmit a message containing the user ID and a command to the device having the device ID,
wherein the device is configured to:
receive the message, and compare the user ID contained in the message and the written user ID; and
determine whether the command contained in the message is executable in accordance with a result of the comparison.

### Claim 2 (depends on 1)

The device control system according to claim 1, wherein when the user ID contained in the message and the written user ID are determined to be different from each other in the comparison, the device avoids executing the command contained in the message.

### Claim 3 (depends on 1)

The device control system according to claim 1, wherein when the server receives an operation instruction directed to the device, the server generates a message containing a user ID for identifying a user who has transmitted the operation instruction.

### Claim 4 (depends on 1)

The device control system according to claim 1, wherein when the user ID contained in the message and the written user ID are determined to be the same in the comparison, the device executes the command contained in the message.

### Claim 5 (depends on 1)

The device control system according to claim 1, further comprising a control device configured to transmit the instruction to register the user ID to the device,
wherein the control device is configured to transmit the device ID of the device to the server,
wherein the server is configured to store the device ID and the user ID associated with each other, and
wherein when the server acquires from the user an operation instruction directed to the device, the server transmits, based on the acquired operation instruction, a message containing the user ID of the user having issued the instruction and the command, to the device having the device ID associated with the user ID.

### Claim 6

A device, which has a device ID for identifying the device, and is configured to:
write a user ID for identifying a user in a memory based on an instruction to register the user ID;
receive a message containing the user ID and a command, and compare the user ID contained in the message and the written user ID; and
determine whether the command contained in the message is executable in accordance with a result of the comparison.

### Claim 7

A computer-readable non-transitory storage medium for storing a program that causes a device which has a device ID for identifying the device to execute processing of:
writing a user ID for identifying a user in a memory based on an instruction to register the user ID; and
receiving a message containing the user ID and a command, comparing the user ID contained in the message and the written user ID, and determining whether the command contained in the message is executable in accordance with a result of the comparison.
