The present invention relates to an access control system using a recognition technology, and more particularly, to a message output in an access control system for outputting a stored message when the information recognized through iris recognition matches the recognition information stored in the database.

Common biometric technologies include speech recognition, fingerprint recognition, and iris recognition. Among these biometric technologies, in the case of voice recognition, it is impossible to recognize when the user's neck is rested, and there is a high probability of error when recording or intentionally mimicking the voice of another person, and in the case of fingerprint recognition, sweat or There is a disadvantage in that the false recognition rate increases when water, stains, etc. are stained.

Among biometrics, iris recognition has the advantage of higher recognition rate and more accurate recognition than other biometrics.

The iris recognition system is a system that authenticates an individual by comparing the characteristic pattern of the iris in the iris image photographed by a video camera using image processing technology and comparing it with previously registered iris data.

In such an iris recognition system, the performance depends on how fast and how accurately the iris recognition is performed.

1 is a block diagram of a general iris recognition system, as shown in FIG. 1, for measuring the distance to the user using an infrared sensor and to inform the user of whether the system is activated and recognized. Through the external indicator 103, the illumination device 104 for adjusting the illuminance at the time of iris image irrespective of the surrounding brightness, the optical window 105 for positioning the user's eyes, and through the optical window Cold mirror 106 for blocking the incoming infrared rays and blocking the visible light, a camera 107 for photographing the iris image of the user transmitted through the cold mirror, and a frame grabber for processing the photographed iris image And a distance measurement value measured by the distance sensor 101 to determine whether the user is within the operating range, and automatically recognizes the iris. And a control device 109 for adjusting the light intensity, and an optical image driver 102 for controlling the operation of the external indicator 103 and the lighting device 104 by the control of the control device.

Looking at the operation of the general iris recognition device configured as described above are as follows.

When the user approaches the iris recognition system, the distance measuring sensor 101 measures the distance to the user and transmits the distance to the control device 109.

The control device 109 determines whether the received distance measurement value is within the operating range. If the determination result is within the operation range, the control signal is output to the optical image driver 102 to prepare for iris image extraction.

The optical image driver 102 sends an active signal to the external indicator 103 to inform the user that the system has been activated.

After the user approaches the optical image driver 102 and places the eye on the optical axis of the camera 107 through the optical window, the cold mirror 106 passes infrared light and blocks visible light.

In addition, the cold mirror displays a portion where the iris should be located so that the user can easily check whether or not his eyes are positioned on the optical axis of the camera 107.

Thereafter, the control device 109 drives the camera 107 to control the photographing of the iris image.

When the iris image photographed by the camera 107 is provided to the frame grabber 108, the frame grabber 108 processes the signal to be suitable for image analysis and provides the same to the controller 109.

The control device 109 receiving the processed signal informs the user whether the recognition is performed through the external indicator 103 through the optical image driver 102.

At this time, the obtained iris image is compared with the iris image preset in the database to control the opening and closing of the door.

However, the conventional access control system operated as described above cannot deliver a message to another user when the user goes out.

       Therefore, the present invention is to solve the above problems, it is proposed that the message that the user wants to be delivered when the user is out or away.

At least one or more of the database unit, the function unit, the memory unit, and the input unit may be configured together with the recognition unit or exist as a separate device. have.

As an example of the present invention, the input unit may be a display means for selecting a message to be transmitted by displaying a message stored in a microphone or a memory for inputting a message to be delivered.

In addition, as an example of the present invention, the memory unit selects a destination to which a message is to be delivered and stores it in association with the message to be delivered.

The access control system of the present invention comprises the steps of: database the identification information of the user; Storing a message to be forwarded; Recognizing a user; Comparing the recognized information with the databased recognition information; And outputting the stored message as a result of the comparison.

As an example of the present invention, the storing of the message may include at least one of selecting and storing a message among newly input or previously stored messages.

In addition, as an example of the present invention, the storing of the message may be performed by selecting a destination to which the message is to be delivered and interworking with the destination to which the message to be delivered is delivered.

In addition, as an example of the present invention, the step of outputting the stored message outputs the stored message in connection with the message recognition information, when the recognized user is a target to deliver the message.

Other objects and features of the present invention will become apparent from the detailed description of the embodiments with reference to the accompanying drawings.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
