## Abstract

As information output device includes: a first output unit that outputs acquired information acquired by a sensor; and a second output unit that converts personal information included in the acquired information into attribute information from which identification of an individual is impossible, and outputs the attribute information.

## Claims

### Claim 1

An information output device comprising:
a first output unit that outputs acquired information acquired by a sensor; and
a second output unit that converts personal information included in the acquired information into attribute information from which identification of an individual is impossible, and outputs the attribute information.

### Claim 2 (depends on 1)

The information output device according to claim 1, wherein the first output unit encrypts the acquired information, and outputs the encrypted acquired information.

### Claim 3 (depends on 1)

The information output device according to claim 1, further comprising:
an output determination unit that determines whether personal information is included in the acquired information,
wherein the second output unit converts personal information into attribute information only in a case where the output determination unit has determined that personal information is included in the acquired information.

### Claim 4 (depends on 1)

The information output device according to claim 1, further comprising:
an output determination unit that determines whether personal information is included in the acquired information,
wherein the first output unit encrypts the acquired information in a case where the output determination unit has determined that personal information is included in the acquired information.

### Claim 5 (depends on 1)

The information output device according to claim 1, wherein the attribute information includes gender and age group of the individual.

### Claim 6 (depends on 1)

The information output device according to claim 1,
wherein the acquired information includes time series position information of the individual, and
the second output unit calculates a movement path of the individual from the time series position information of the individual, and outputs the attribute information including the movement path.

### Claim 7 (depends on 1)

The information output device according to claim 1,
wherein the acquired information includes a plurality of time series image data representing an at-shelf behavior of the individual, and
the second output unit converts the at-shelf behavior of the individual into information represented by text data, and outputs the attribute information including the information represented by text data.

### Claim 8

(canceled)

### Claim 9 (depends on 1)

A camera comprising the information output device according to claim 1.

### Claim 10

An information output system comprising:
an information output device comprising a first output unit and a second output unit, the first output unit encrypting acquired information acquired by a sensor and outputting the encrypted acquired information, the second output unit converting personal information included in the acquired information into attribute information from which identification of an individual is impossible and outputting the attribute information;
a first server terminal device that acquires the acquired information output by the first output unit; and
a second server terminal device that acquires the attribute information output by the second output unit,
wherein the first server terminal device comprises a decryption unit that decrypts the acquired information.

### Claim 11 (depends on 10)

The information output system according to claim 10,
wherein the first server terminal device further comprises a key generation unit that generates an encryption key, and
the first output unit acquires the generated encryption key, and encrypts the acquired information using the encryption key.

### Claim 12 (depends on 10)

The information output system according to claim 10,
wherein the information output device is connected to an external connection device storing an encryption program, and
the first output unit executes the encryption program stored on the external connection device, to encrypt the acquired information.

### Claim 13

(canceled)

### Claim 14

An information output method comprising:
outputting acquired information acquired by a sensor; and
converting personal information included in the acquired information into attribute information from which identification of an individual is impossible, and outputting the attribute information.
