## Abstract

A measurement device includes: a short-range wireless communication interface; a processor; and a storage. In a state where a communication connection with an information terminal using short-range wireless communication is established, the processor receives, from the information terminal, user information specifying a user of the information terminal, shares, with the information terminal, encryption information for performing encryption communication using short-range wireless communication, and stores the encryption information and the user information in the storage in association with each other.

## Claims

### Claim 1

A measurement device, comprising:
a short-range wireless communication interface;
a processor; and
a storage, wherein
in a state where a communication connection with an information terminal using short-range wireless communication is established, the processor receives, from the information terminal, user information specifying a user of the information terminal, shares, with the information terminal, encryption information for performing encryption communication using short-range wireless communication, and stores the encryption information and the user information in the storage in association with each other.

### Claim 2 (depends on 1)

The measurement device according to claim 1, wherein
when the processor receives, from an information terminal, information that is same as first user information stored in the storage and when the processor shares new encryption information with the information terminal, the processor replaces the encryption information corresponding to the first user information with the new encryption information shared with the information terminal.

### Claim 3 (depends on 1)

The measurement device according to claim 1, wherein
when the processor receives, from an information terminal, information that is same as first user information stored in the storage, when the processor shares new encryption information with the information terminal, and when the processor receives, from the information terminal, a request to additionally register the new encryption information for the first user information, the processor stores the new encryption information in the storage in association with the first user information.

### Claim 4 (depends on 1)

The measurement device according to claim 1, wherein
when the processor receives a deletion request for user information stored in the storage from an information terminal, the processor deletes the user information and the encryption information corresponding to the user information.

### Claim 5 (depends on 1)

The measurement device according to claim 1, wherein
when the processor receives, from an information terminal, a change request for user information stored in the storage, the processor changes the user information to designated information.
