That is, in the publications described in these publications, a terminal device is provided with a voiceprint detecting unit, a fingerprint detecting unit, and the like, and the voiceprint and fingerprint detected by the voiceprint detecting unit, the fingerprint detecting unit, and the like are registered in the terminal device in advance. Only when the fingerprint matches the fingerprint, it is determined that the operation is performed by a pre-registered authorized operator, and the key of the vehicle can be unlocked. Even if the user happens to get and operate the terminal device, the key of the vehicle is not unlocked immediately, and the security is considerably safe.
[0003]
[Problems to be solved by the invention]
However, any of those described in these publications authenticates the operator on the terminal side, and enables the key of the vehicle to be unlocked based on the result, and the terminal is informed in advance of the authorized operator. Voiceprints, fingerprints, etc. are registered.
[0004]
Therefore, in this type of device, it cannot be said that there is no possibility that a third party who happens to have obtained the terminal device may illegally register his / her own voiceprint or fingerprint in place of the voiceprint or fingerprint of the authorized operator. When such a change registration is performed, there is a problem that it can be used as it is by a third party.
[0005]
The present invention has been made in view of the above-mentioned conventional problems, and even if a third party obtains a terminal device, the terminal device illegally prints its own voiceprint and fingerprint instead of the voiceprint and fingerprint of a regular operator. The present invention provides an excellent remote control system with high security that cannot be registered and used.
[0006]
[Means for Solving the Problems]
A remote control system according to the present invention is a remote control system including a terminal device and a controlled device that operates in accordance with an instruction from the terminal device, wherein the terminal device reads biometric information of a current operator who operates the terminal device. The control unit includes a reading unit and a transmitting unit that transmits biometric information, the controlled device receives a biometric information from the terminal device, and a storage unit that stores biometric information of a valid operator in advance. If the biometric information received by the receiving unit matches the biometric information of the authorized operator stored in the storage unit in advance, and the current operator is authenticated as the authorized operator, the Operating means for performing an operation in accordance with the instruction.
[0007]
With this configuration, the biometric information of the legitimate operator is registered in the controlled device, and it is not necessary to register the biometric information of the operator in any portable terminal device that is easily misplaced or dropped. Even if the terminal is forgotten or dropped, and a third party illegally obtains it, there is an effect that no operation can be performed depending on the terminal device.
[0008]
Further, the remote control system of the present invention is configured such that the biological information includes at least one of an operator's iris, retina, fingerprint, palm print, voice print, face, pinna, blood vessel image, and signature. With this configuration, the biometric information of the authorized operator can be limited to one, which is extremely advantageous in terms of security.
[0009]
Further, in the remote control system of the present invention, the controlled device is mounted on a vehicle, and the operating means is a means for opening / closing an opening / closing section of a moving body or a means for opening / closing a key of the opening / closing section. . With this configuration, the biometric information of an authorized operator for authentication is registered in a controlled device mounted on a moving body such as a vehicle. Since the key of the opening / closing part such as the door is closed, the controlled device mounted inside the moving body cannot be touched, and has the effect of not being tampered with.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a remote control system according to an embodiment of the present invention will be described in detail with reference to the drawings.
[0013]
FIG. 1 is a block diagram showing the configuration of a remote control system according to an embodiment of the present invention, FIG. 2 is an external view of a terminal device constituting the remote control system, and FIGS. It is a flowchart.
[0014]
A remote control system according to an embodiment of the present invention includes a terminal device 1 and a controlled device 2 that receives a command from the terminal device 1 and performs a predetermined operation. The exchange of signals between the terminal device 1 and the controlled device 2 is performed wirelessly.
[0015]
As shown in FIG. 1, the terminal device 1 includes a reading unit 11 for reading an iris of an operator, an operation unit 12 for inputting various information and commands, a display unit 13 for displaying various information, The communication unit 14 includes a communication unit 14 that communicates with the device 2 and a control unit 15 that controls the communication unit 14. As shown in FIG. 2, all of these components constituting the terminal device 1 are housed in one portable case 100, and the camera 101 and the operation unit 12 constituting the reading unit 11 are The constituent keys 102a, 102b, 102c, 102d and the display 103 constituting the display unit 13 are appropriately arranged on the front surface of the case 100.
[0016]
The controlled device 2 is, for example, a device mounted on a vehicle, and includes a communication unit 21 that communicates with the terminal device 1 and a storage unit 22 that previously stores iris information and the like of an authorized operator. , A key opening / closing unit 23 for opening / closing a key in a vehicle door, and a control unit 24 for controlling these.
[0017]
Next, the operation of this embodiment will be described in detail with reference to FIGS.
[0018]
First, an operation for starting authentication is performed using one predetermined key (authentication start key) 102a of the operation unit 12 (step (referred to as S in the drawing) 301), and this is displayed on the display unit 103 (step 301). 302), the control unit 15 generates a reference signal of a predetermined constant level under the control of the control unit 15. Therefore, when another key (transmission key) 102b is operated at this stage, the previously generated reference signal is transmitted to the controlled device 2 via the communication unit 14 (step 303).
[0019]
When the reference signal is transmitted to the controlled device 2 (step 303), the reference signal is received by the communication unit 21 of the controlled device 2 (step 304), and the controlled signal is controlled based on the level of the received reference signal. The electric field intensity of the radio wave from the terminal device 1 in the device 2 is measured (step 305). When the electric field intensity is measured, it is determined whether or not the electric field intensity is equal to or greater than a predetermined value (step 306). If the electric field intensity is equal to or less than the predetermined value (N in step 306). If the value is equal to or greater than a predetermined value (Y in step 306), an ACK signal to that effect is output, and the terminal device 1 (Step 307).
[0020]
When the ACK signal is transmitted to the terminal device 1, the ACK signal is received by the communication unit 14 of the terminal device 1 (Step 308), and the display 103 indicates that the ACK signal has been received (Step 309). Therefore, in this state, if the operator looks at the camera 101, the camera 101 photographs the iris of the operator, and the reading unit 11 reads the iris (step 310).
[0021]
When the iris is read, the iris is coded (step 311). When the transmission key 102 is operated again at this stage, the coded iris is transmitted via the communication unit 14 to the controlled device 2 side. (Step 312).
[0022]
When the iris code is transmitted to the controlled device 2, the code is received by the communication unit 21 of the controlled device 2 (step 313), and is compared with the iris code of the normal operator stored in the storage unit 22 in advance. Then, so-called authentication is performed (step 314). As a result of the authentication, when it is determined that the user is not a legitimate operator (N in step 315), the subsequent operations are stopped and terminated, and when it is determined that the user is a legitimate operator (Y in step 315). ), The result is transmitted to the terminal device 1 via the communication unit 21 (step 316).
[0023]
When the authentication result is transmitted to the terminal device 1, the authentication result is received by the communication unit 14 of the terminal device 1 (step 317) and displayed on the display 103 (step 318). At the stage when the authentication result is displayed on the display 103, when further keys (operation instruction keys) 102c and 102d constituting the operation unit 12 are operated, the operation contents corresponding to the operated keys 102c and 102d are performed. Is transmitted to the controlled device 2 via the communication unit 14 (step 319).
[0024]
The controlled device 2 receives the operation content (Step 320), performs an operation according to the operation content (Step 321), and transmits the result to the terminal device 1 (Step 322). That is, in the present embodiment, the controlled device 2 is mounted on the vehicle, and the key opening / closing section 23 of the controlled device 2 is configured to control opening and closing of the key of the vehicle door, and the key 102c is operated. In this case, the door key is unlocked, and when the key 102d is operated, the door key is closed. Then, the result is transmitted to the terminal device 1 (step 322).
[0025]
When the operation result of the operation according to the operation content is transmitted to the terminal device 1, the result is received by the communication unit 14 of the terminal device 1 and displayed on the display 103. Therefore, if the display on the display unit 13 is viewed, it becomes clear at a glance whether the key has operated normally.
[0026]
In the present embodiment, the following procedure is used to detect and code an iris. That is, as shown in FIG. 4, with the user's eyes pointed at the camera 101, the camera 101 continuously shoots an image of the face including the eyes (step 401), and determines the shooting state (step 402). If the size or position of the eyes falls within a predetermined range, it is determined as OK (Y in step 403), the reflected light is detected and removed (step 404), and the eyelid line is detected (step 405). If the size or position of the imaged eye does not fall within the predetermined range, the photographing is continued as NG (N in step 403).
[0027]
Then, polar coordinate transformation of the iris portion is performed based on the results of detection and removal of the reflected light, detection of the eyelid line, and the like (step 406), and coding of the iris portion by a band-pass filter is performed (step 407).
[0028]
In this way, the iris portion is coded into an iris code of, for example, several hundred bytes, and the iris code of the authorized operator is stored in the storage unit 22 of the controlled device 2 and the operator's respective time is stored. The iris code is transmitted from the transmitting unit 14 of the terminal device 1 to the controlled device 2 for authentication.
[0029]
As described above, according to the present embodiment, the iris of the authorized operator used for authentication is stored in the controlled device 2, and the iris of the operator at each time is transmitted from the terminal device 1. Since the information is simply transmitted to the controlled device 2 side, even if the terminal device 1 is misplaced or dropped and illegally obtained by a third party, the obtained terminal device 1 can be operated properly. Cannot be impersonated, and is more advantageous in terms of security than conventional ones.
[0030]
In particular, when the controlled device is mounted on a vehicle or the like, and the controlled device is a key of a door of a vehicle or the like, the controlled device itself is placed in a locked vehicle. As a result, it is impossible to change the iris and the like of the authorized operator stored in the controlled device unless the key is unlocked, and it is possible to easily prevent the iris from being changed as appropriate by a third party. be able to.
[0031]
Further, according to the present embodiment, the electric field strength in communication with terminal device 1 is measured in advance before controlled device 2 controls a key or the like, and the measurement result is equal to or less than a predetermined value. In this case, the subsequent operations are not performed, and the keys and the like are not controlled.Therefore, when the terminal device is far away from the controlled device, the keys and the like are not controlled. In terms of security, it is more advantageous than the conventional one.
[0032]
Then, in this case, a reference signal of a predetermined constant level is transmitted from the terminal device 1 in advance, the controlled device 2 receives this reference signal, and measures the level to determine the electric field strength. By setting a predetermined constant level arbitrarily, there is an advantage that it is easy to set how far the terminal device 1 becomes unusable from the controlled device 2.
[0033]
In this embodiment, each time a terminal device 1 transmits a reference signal, an iris code, an operation instruction signal, and the like to the controlled device 2, how the controlled device 2 operates is described. Although the controlled device 2 transmits the result to the terminal device 1 each time, these results do not necessarily need to be transmitted to the terminal device 1.
[0034]
Of course, as in the present embodiment, if the result is transmitted to the terminal device 1 each time, the result is displayed on the terminal device 1, and further, the guidance of the next operation can be displayed based on the result. Thus, the terminal device 1 can be operated more easily for the operator.
[0035]
Also, in the present embodiment, the iris is used for authentication, but it goes without saying that retina, fingerprint, palm print, voice print, facial appearance, pinna, blood vessel image, signature, and other biometric information may be used.
[0036]
Further, in the present embodiment, the controlled device 2 is mounted on the vehicle, and the controlled device 2 opens and closes the key of the vehicle door. In addition to the opening and closing of the key, in addition to the opening and closing of the window, It goes without saying that adjustment of the seat and the like may be performed, and various devices other than the vehicle may be controlled.
[0037]
【The invention's effect】
As described above, according to the remote control system of the present invention, the biometric information of the authorized operator is registered in the controlled device, and the terminal device that is portable and easily misplaced or dropped includes the operator. Because no biometric information is registered, even if a terminal device is misplaced or dropped and illegally obtained by a third party, depending on the terminal device, it is not possible to impersonate a legitimate operator Has the effect of not being used illegally.
