6. The information output device according to claim 1 , wherein the processor is further programmed to acquire the attribute information by using a detection result obtained by a detector of a detection device, the detector detecting user access to the area.

7. The information output device according to claim 1 , wherein the processor is further programmed to acquire the attribute information by using schedule information indicating a schedule of access to the area.

8. The information output device according to claim 1 , wherein, when enabling the authenticated output function, if information is being output while the authenticated output function is disabled, the processor is further programmed to stop outputting the information before enabling the authenticated output function.

9. The information output device according to claim 1 , wherein the processor is further programmed to:

prevent a user from accessing the area if information is being output while the authenticated output function is disabled.

10. The information output device according to claim 9 , wherein the processor is further programmed to:

stop preventing a user from accessing the area when outputting of the information while the authenticated output function is disabled has finished.

11. The information output device according to claim 1 , wherein, after the authenticated output function has been enabled, if a distance between the information output device and a user having attribute information for which the authenticated output function will be enabled is a predetermined distance or greater, the processor is further programmed to disable the authenticated output function.

12. The information output device according to claim 11 , further comprising:

a communication interface that communicates with a terminal of the user by using radio waves,

wherein the processor is further configured to find the distance between the information output device and the user by using strength of radio waves received from the terminal by the communication interface.

13. The information output device according to claim 12 , wherein the processor is further programmed to determine that the distance between the information output device and the user is the predetermined distance or greater when communication between the communication interface and the terminal is disconnected.

14. A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:

acquiring attribute information concerning an attribute of a user having accessed an area where access control is performed;

acquiring a setting condition for setting an authenticated output function, the authenticated output function being a function for demanding authentication for outputting information; and

determining from the acquired attribute information whether the attribute of any of the users in the area satisfies the setting condition, and determining whether the authenticated output function is disabled or enabled;

if a determination is made that the attribute of a user in the area satisfies the condition and that the authenticated output function is disabled, enabling the authenticated output function; and

if a determination is made that no user in the area satisfies the setting condition and that the authenticated output function is enabled, disabling the authenticated output function.

15. An information output system comprising:

an information output device including a processor programmed to:

acquire attribute information concerning an attribute of a user having accessed an area where access control is performed,

acquire a setting condition for setting an authenticated output function, the authenticated output function being a function for demanding authentication for outputting information, and

determine from the acquired attribute information whether the attribute of any of the users in the area satisfies the setting condition, and determine whether the authenticated output function is disabled or enabled;

if the processor determines that the attribute of a user in the area satisfies the condition and determines that the authenticated output function is disabled, enable the authenticated output function; and

if the processor determines that no user in the area satisfies the setting condition and determines that the authenticated output function is enabled, disable the authenticated output function; and
