DETAILED DESCRIPTION OF THE INVENTION Field of Application of the Invention The present invention relates to improvements in important information service systems using telephones and the like.

Prior Art Conventionally, in information service systems using telephone lines, in order to prevent unauthorized use, a user is recognized as a legitimate user when there is a specific relationship between a code that is recited from a push button dial and a pre-registered code. provided information. However, reciting the code alone is not sufficient to prevent unauthorized use.

Purpose of the Invention The purpose of the present invention is to provide a more secure information service system by adding a new means to verification by reciting code verification.

General Description of the Invention The main point of the present invention is that when a center device receives a request for information service, the line is temporarily disconnected and the center side connects the line to the requester to determine whether or not the user is an authorized user. This is what I'm trying to confirm.

EXAMPLES Hereinafter, the present invention will be explained in detail with reference to examples. FIG. 1 is a block diagram illustrating one embodiment of the present invention. A person (user) who wishes to receive an information service requests the service from an information center 10 via a telephone line network 2 from a push-button telephone or a telephone having an equivalent function. The request is displayed as a combination of pushbutton signals, passed through the transmission/reception switch 3, and decoded by the pushbutton signal receiver 4.
The code is sent to the control unit 6 as a code. The center 10 uses the voice response device 5 to allow the user to input a telephone number, a first recitation code, and the like. When the user is confirmed to be an authorized user based on the first recited code, the center 10 activates the voice response device and instructs the user to "hang up the phone and wait."
Have the phone hang up. The control unit 6 records the user's telephone number in the storage device 8, calls the user using the automatic calling device 7, confirms whether the user is the user using a second recitation code, etc., and then starts the service. . It goes without saying that the first and second recitation codes may be speaker identification based on tone.

Summary As explained above, according to the present invention, it is possible to legally perform reverse detection of a user, and it can also be used as important evidence in the event that suspicion arises at a later date, exerting great power in preventing fraud.
