Photoreceivers 23 to 26, which prestore target IDs, transmit the illumination ID based on the visible light 22a and the prestored target IDs as data when receiving the visible light 22a. A processing unit 30 associates the photoreceivers 23 to 26 located in the illumination area of the same first luminaire 22 based on the data transmitted from the photoreceivers 23 to 26. Treatment is authenticated by deciding whether or not a combination of the associated photoreceivers 23 to 26 matches a combination of the photoreceivers based on a treatment order. ## Claims ### Claim 1 An authentication system authenticating treatment based on a treatment order in a facility, the system comprising: a light source that emits illumination light including an illumination ID for specifying a location in the facility as information; a plurality of photoreceivers that transmit the illumination ID based on the illumination light and a prestored target ID when receiving the illumination light from the light source as data; and a processing unit that associates the photoreceivers located in an illumination area of the same light source based on the data transmitted from the photoreceivers, and then authenticates treatment by deciding whether a combination of the associated photoreceivers matches a combination of the photoreceivers based on the treatment order. ### Claim 2 (depends on 1) The authentication system in a facility according to claim 1, wherein the treatment order is an order of treatment performed on a subject in a predetermined time period, and the combination of the photoreceivers at least includes the photoreceiver attached to the subject and the photoreceiver attached to a person in charge of treatment on the subject. ### Claim 3 (depends on 2) The authentication system in a facility according to claim 2, wherein the light source includes a main light source and a sub light source that emit illumination light including the same illumination ID as information. ### Claim 4 (depends on 3) The authentication system in a facility according to claim 3, wherein the sub light source is mounted at a lower position than the main light source. ### Claim 5 (depends on 4) The authentication system in a facility according to claim 4, wherein the main light source is mounted on a ceiling, and the sub light source is mounted around the subject. ### Claim 6 (depends on 1) The authentication system in a facility according to claim 1, wherein the illumination light is visible light. ### Claim 7 (depends on 1) The authentication system in a facility according to claim 1, wherein the light source is an LED lamp. ### Claim 8 (depends on 3) The authentication system in a facility according to claim 3, wherein the sub light source horizontally emits the illumination light to the subject. ### Claim 9 (depends on 3) The authentication system in a facility according to claim 3, wherein the sub light source is mounted at a height of 1 m from a floor surface of the facility. ### Claim 10 (depends on 3) The authentication system in a facility according to claim 3, wherein the light source superimposes the illumination ID on the illumination light by modulating an illuminance of the emitted illumination light, and the sub light source modulates an illuminance in synchronization with illuminance modulation by the main light source. ### Claim 11 (depends on 3) The authentication system in a facility according to claim 3, wherein the sub light source lights up when the photoreceiver attached to the subject and the photoreceiver attached to the person in charge of treatment are located in the illumination area of the main light source. ### Claim 12 (depends on 2) The authentication system in a facility according to claim 2, wherein after the treatment is authenticated, the processing unit authenticates a movement of a device for treatment on the subject by deciding whether or not the photoreceiver attached to the person in charge of treatment on the subject and the photoreceiver attached to the device for treatment on the subject are located in the illumination area of the same light source. ### Claim 13 (depends on 2) The authentication system in a facility according to claim 2, wherein the processing unit further includes a recording unit that records information for specifying information on a treatment time, information on a location of treatment, information for specifying the person in charge of treatment, and information for specifying the treated subject. ### Claim 14 (depends on 1) The authentication system in a facility according to claim 1, wherein if the treatment is authenticated, the processing unit notifies at least one of the photoreceivers of the authentication.
