DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment using the information equipment of the present invention will be described below with reference to FIGS. still,
In this example, the information device stores and holds an authentication code for personal use as data, and uses the authentication code,
An example in which the authentication system is used to authenticate that the user is a legitimate user will be described, but the present invention is not limited to this.

In the present embodiment, the data held in the information device is not limited to the authentication data assigned to the individual, but also includes, for example, data used for various purposes.

In this embodiment, an example will be described in which the external authentication system is used for a security gate that permits a properly authenticated user to pass through the gate, but the present invention is not limited to this.

As shown in FIG. 2, this security gate 5
0 is basically a microcomputer that controls the opening and closing of the gate door 51. The terminal device 52 sends an inquiry to an information device and receives an authentication code to which the information device responds, and the terminal device 52 receives the authentication code. The CPU 53 includes a memory 53a storing information and a program for determining the validity of the authentication code, and a gate door 51 that is opened by a door driving device when the CPU 53 determines that the code is valid. I have.

As shown in FIGS. 1 and 2, the information device 10 is configured to be small and lightweight, which can be worn on a human body and portable, and is basically used only by the individual user. . The user enters the information device 10 for the user,
Various types of data such as authentication data are input, and the authentication check by an external authentication system such as the above-described security gate 50 is properly and smoothly passed using the authentication data while the information device 10 is mounted. It is.

That is, the information device 10 is basically a wrist-type small and lightweight portable device which is easily attached to and detached from the user's arm, and has the same appearance as a normal wristwatch. As well as a wristwatch, it is possible to wear comfortably with less discomfort and a sense of burden, and to ensure sufficient operability and confirmation of an operation state.

The information device 10 includes a small and lightweight device body 11, a belt-shaped mounting member 12 for easily mounting the device body 11 to a user, and an information device 10
And attachment / detachment detecting means 13 for judging the state of attachment to the user. The device main body 11 includes an operation input unit 14 for inputting various codes and setting operation of the information device 10, and a display unit 15 for displaying various information to a user.
A CPU 16 having a memory 16a for performing various processes according to a predetermined program; and a terminal device 52 connected to the CPU 16 via an I / O interface unit 17a and provided in an external authentication device. And a communication unit 17 that communicates with the user.

The device main body 11 has a built-in secondary battery of a predetermined capacity so that sufficient operating power can be obtained from the secondary battery while the information device 10 is in portable use. I have to.

Further, the operation input unit 14 of the device main body 11
And the display unit 15 is installed in a place where the user can easily see and operate, and while the user sufficiently checks the operation contents and the like,
Operation input is enabled.

That is, the operation input unit 14 is configured by arranging a predetermined number of select buttons for setting various operations on the information device 10 and a plurality of small switches for inputting codes.

Therefore, the user can operate and set the information device 10 while carrying the information device 10 in a portable manner.

That is, since input operation and correction can be performed using the operation input unit 14 of the information device 10 at any place, a flexible measure can be taken, and the handleability can be improved.

For example, if there is an input error in the authentication data and the user finds the error at a place where the user performs authentication, it is possible to immediately correct the input error at that place and pass the authentication. It becomes possible.

Further, the display unit 15 is disposed at least on the front side of the device main body 11 when worn on the arm of the user, and has a relatively large area on the front side as a display surface. A display mechanism or the like is used.

The display unit 15 displays input data such as codes and characters input by the user and operation modes and the like set by the operation as character and graphic information. Information equipment 10 at present
It is possible to easily grasp the operation status, setting status, and the like.

Further, using a timer function such as a timer and a calendar provided in the CPU 16, information relating to various times such as the current time can be acquired and displayed.

Therefore, when the information device 10 is used in a portable manner, it is not necessary to carry a separate wristwatch to know the time, and the burden on the user can be reduced.
Since the appearance design is the same as that of a wristwatch, the appearance of strangeness to others is reduced, and convenience can be improved.

The CPU 16 having the memory 16a
Has a general microcomputer configuration, stores and holds various information data and programs in the memory 16a, and controls data processing and each unit of the information device 10 based on the programs.

The program defines various functional operations of the information device 10 described later.

Further, as the communication unit 17, the one corresponding to the terminal device 52 provided in the external authentication device is used.
The communication operation according to the authentication procedure specified by the external authentication device is enabled.

That is, the communication unit 17 performs non-contact communication so that various data for authentication can be transferred to and from the terminal device 52 of the authentication device.

Although it depends on an external authentication device, if it is a non-contact type communication method, it is necessary to select an optimum communication method from various communication methods such as weak radio, infrared rays, ultrasonic waves, etc. in terms of use conditions and cost. Also, a plurality of communication means may be simultaneously mounted on the information device 10 according to different communication methods of different authentication systems.

In this example, the information device 10
Of the information device 10 and the terminal device 52 of the authentication device.
If there is an obstruction on the straight line between the information device 10 and the communication device, such as an infrared ray or an ultrasonic wave, which hinders or impairs the communication operation between the two, the position of the information device 10 can be easily changed.
An obstacle can be avoided, and the reliability of the communication operation can be sufficiently ensured.

The information device 10 further includes a mounting member 12
, So that it can be easily attached to and detached from the user's wrist, and can be stably attached when worn.

That is, when the mounting member 12 is mounted, the mounting member 12 is wrapped around the mounting site of the user. For example, in the example shown in FIG. 3, a three-fold metal fitting 21 for maintaining the wrapped state is provided. Also, by using the three-fold metal fitting 21, the mounting member 12 is not divided into two as described later,
Is maintained in a ring shape as a whole, and when not mounted, the inner diameter of the ring is expanded so that the ring can be expanded.

The mounting member 12 is composed of a single member formed in a relatively wide band of a predetermined length using a material having a predetermined flexibility, and has a middle portion in the longitudinal direction. At the location, a three-fold metal fitting 21 that can be folded and unfolded is provided.

It should be noted that a high quality material such as leather may be used as the material of the mounting member 12 so as to obtain a comfortable wearing feeling and a high quality feeling.

The three-fold metal fitting 21 is made of a metal material having a predetermined strength, and is composed of at least three bent plate-shaped members connected to each other so as to be overlapped with each other from an expanded state and folded. The folded state can be maintained by an engagement structure provided at a predetermined position of the outermost curved plate-shaped member.

That is, when the three-folded metal fitting 21 is deployed, at least the inner diameter of the entire mounting member including the three-folded metal fitting 21 is expanded to a size that allows the user's hand to pass through (the diameter is increased). On the other hand, when the three-folded metal fitting 21 is folded, the inner diameter is reduced (reduced) to about the outer diameter of the user's wrist.

Therefore, when the user wears the information device 10 on his / her wrist, the mounting member 12 has a three-fold metal fitting 21.
After leaving the hand of the user with
By folding near the wrist, the information device 10 can be easily and stably mounted on the wrist of the user via the mounting member 12.

Although the description is simplified, at least the pin connection positions of the two members of the three-folded metal fitting 21 can be changed in the longitudinal direction along the outer peripheral direction of the mounting member 12. Accordingly, the circumference of the entire mounting member 12 when the three-folded metal fitting 21 is in a folded state is adjusted, so that different wrist thicknesses can be applied to different users.

The attachment / detachment detecting means 13 for judging the attachment / detachment state of the information device 10 is provided with a relatively inexpensive micro switch or pressure-sensitive sensor 22 on the opposed and overlapping surfaces of the three-fold metal fitting 21. The switch or the sensor is electrically connected to the main body of the information device 10. When the three-fold metal fitting 21 is folded, that is, when the information device is attached to the user, the switch or the sensor signal is output. Is to be obtained.

Therefore, the attachment / detachment state of the information device 10 can be determined based on the detection signal from the micro switch or the pressure sensor 22 disposed on the three-fold metal fitting 21 of the mounting member 12 as described above.

The attachment / detachment detection means 13
When it is determined that the information device 10 has been separated from the user, a data security operation for protecting data for an unspecified other person than the user is started.

That is, the data security operation is started after a predetermined hold time elapses from the time when the detachment of the information device 10 is detected.

Accordingly, since the hold time is provided before the start of the data security operation, even if the user detaches the information device 10 from the human body for a relatively short period of time for any reason. Even without performing a specific operation, the information device 10 can be mounted again and can be used continuously, and the handling property can be improved.

The hold time is a variable time that can be arbitrarily set, including 0 second, by a user's specific operation, even if the fixed time is fixedly set in advance in accordance with use conditions and the like. It may be configured so that both can be selected as appropriate.

Further, the data security operation is started when the detachment of the information device 10 is detected. However, even if the function for disabling the use of the data is suspended for a predetermined time, it is practically possible. Are identical.

Next, this data security operation includes at least a first stage in which data can be returned to a usable state;
A second stage in which data is not returned to a usable state unless data is re-input, and a predetermined time for shifting to each stage is set.

That is, the first-stage data security operation means that the user operates the information equipment 10 during the first-stage operation state.
When the user performs a predetermined specific operation while returning to the state in which the information device 10 is mounted, the information device 10 can be returned to a state in which data can be used. After the second stage is activated, even if the user performs a specific operation, the information device 10 is not returned to a state where data can be used.

The return operation during the operation of the first stage also requires that the information device 10 be attached to the user. However, the present invention is not limited to this. Although the data remains unusable, returning to the start time of the above-mentioned holding time, if the information device 10 is attached to the user during this holding time, the data usage of the information device 10 can be performed without performing any additional operation. May be configured to return to a state where it is possible.

Similarly to the hold time described above, the time required to shift to each stage of the data security operation can be set to any value including 0 second by a specific operation of the user, even if it is a fixed time set in advance. The configuration may be such that the variable time is possible, or the user or the like may be able to select from both as appropriate.

Incidentally, while increasing the number of these steps,
The configuration may be such that the operation content of each stage is different, and these may be appropriately selected and set by the user.

That is, for example, in the data security operation in the initial stage, the use of data in the information device 10, that is, the data input and the correction are enabled, but the communication operation between the information device 10 and the outside or the external The output operation may be suppressed, and in the next stage, the use of data in the information device 10 may also be suppressed.

Further, the content of the return operation when the use of data can be returned may be changed stepwise.

In other words, in the return operation in the data security operation at the stage where the data use can be restored, if the stage where the data use can be restored includes a plurality of stages, the process proceeds to the next stage. It may be configured so that it becomes more complicated with time or with the passage of time.

For example, even in a data security operation at a certain stage in which data use can be returned, if a relatively short time has elapsed since the start of the data security operation at this stage, a simple procedure operation can be used. While the use can be restored, a more complicated procedure may be required after a predetermined time has elapsed.

The method of making the data in the information device 10 unusable by the first and second data security operations described above includes a method of directly processing the data held therein and a method of processing various types of data. The method of interrupting the data operation command and the flow of the data itself in the middle of the transmission path is roughly classified.

That is, the method of directly processing data is to delete or change the data itself, and the method of shutting down data is to stop data input / output and management functions or to control external data. When the communication operation is performed with the authentication system, this is a method for suppressing the reception or transmission function of the information device 10, and any of these methods for suppressing functions at various operation levels may be selected or used in combination.

Also, as an actual concrete realizing method,
Design, use conditions and cost of hardware-logic type that inhibits the functional operation of a certain circuit by the circuit configuration, software-logic type that interrupts the flow of data by program control, and the combination of these From the viewpoint, an optimal one may be appropriately selected.

Further, for example, when data is stored after being encrypted, the decryption means is made inoperable or the decryption key code is deleted.

Further, for example, when data is output at least from the storage means to the outside or from the information device 10 to the outside, the data is not output as it is but is scrambled using a circuit or software, and the data is scrambled. And make it unavailable.

In any case, in the information device 10, unless an explicit operation setting is made by the user,
If the information device 10 is left detached from the human body, it is assumed that the information device 10 will not be returned to a state where the data can be used unless data is re-input.

The state in which the data cannot be restored basically means that at least a part or all of the data necessary for the authentication is deleted or deleted. No trace shall be left.

When the information device 10 is in the data security operation state as described above, a warning is given to the user using the display unit 15 or the like, indicating that the data security operation is being performed. The configuration prevents the user from erroneously recognizing that the information device 10 itself has failed because the data cannot be used.

Further, as described above, when a certain hold time is provided for the activation of the data security operation, the messenger warns that the hold time before the execution of the data security operation is in progress. The notification may be made to prevent the user from making useless mistakes.

Also, when the data security operation has at least a first stage in which data use can be returned and a second stage in which data cannot be used unless data is re-input, the same applies. In addition, in addition to the above, the user may be warned that the operation is in the first stage, that is, the suspension time is before the operation of the second stage is performed. Inadvertent use mistakes can be prevented.

Further, for example, the remaining time until each operation is started may be notified to the user by using a display or the like, together with the above. Similarly, the effect of preventing a use error may be enhanced. And at the same time, the handleability as a device can be improved.

In particular, when proceeding to an operation that does not return the data to a usable state, at least before this operation, an aggressive warning using the vibration of the information device 10 and the like is performed in addition to the notification. It is preferable that the user be alerted.

Next, the information device 10 configured as described above
A usage pattern will be described.

The authentication data for causing the external authentication device to authenticate the user as a proper permitter is determined in advance by a system administrator or the like of the authentication system, and is passed from the administrator or the like. .

That is, when the user moves near the terminal device 52 provided at the security gate 50 to pass through the security gate 50, the terminal device 52
The authentication procedure by communication between the information device 10 and the information device 10 is automatically and instantaneously performed.

First, an inquiry signal is transmitted from the terminal device 52 on the side of the security gate 50 using weak radio or the like, and this inquiry signal is transmitted to the communication unit 17 of the information device 10.
Receiving and responding to this inquiry, the authentication process defined by the security gate system is performed,
At least, at the security gate side, it is determined whether or not the user is an appropriate user, and is confirmed.

That is, for example, the authentication data is transmitted from the information device 10 to the terminal device 52 on the reverse path of the inquiry signal, and the authentication data of the information device 10 and the security gate 5 are transmitted.
The authentication data stored in the memory 53a provided in the CPU 53 of the CPU 0 is compared and collated, and if it is determined that they match, the security gate 50 determines that the user is an appropriate user.

When the security gate 50 authenticates the user as an appropriate user, the user can pass through the gate door 51 of the security gate 50. That is, the closed gate door 51 is opened by the door driving device 55 of the security gate 50, and this gate door 51 is opened.
Is kept open at least until the user passes.

When the user moves on to such an authentication system or uses the information device 10 on a daily basis,
For example, when the user removes and misplaces the information device 10 or, contrary to the user's will, removes the information device 10 from the human body of the user, first after a predetermined hold time has elapsed, the first stage is performed. Is started.

The specific operation of returning the information device 10 in such an operation state to a data usable state is, for example, a password input operation set in advance by the user. Accordingly, even if a third party metaphorically picks up the information device 10 in this state, the information device 10 cannot be illegally used unless the third person knows an appropriate password. At the same time, when the user picks up the information device 10 in this state, if the user performs an appropriate password input operation, the information device 10 can be promptly returned to a data usable state.

When the first-stage data security operation is continued for a predetermined relatively long time, the second-stage data security operation is started, and the internal data of the information device 10 is
For example, the data is changed or deleted, and the data use is not returned to a usable state. Therefore, the user performs a procedure for re-acquiring various data for authentication to the administrator of the authentication system, and unless the data is re-input, the data does not return to a usable state. Higher security against unauthorized use by a third party can be ensured, and the security strength of the entire authentication system can be improved.

As described above, according to this example,
In a portable information device that stores predetermined data and uses the data for various purposes in a state where the data is worn on the user's human body, the information device includes a detachment detection unit that detects a detachment state of the user from the human body. At least, when detecting the departure of the information device from the user, at least the data security operation for disabling the data stored in the information device is performed, thereby preventing unauthorized use of the data by an unspecified other person. Is prevented,
High security can be ensured.

That is, by this data security operation,
For example, even when the user inadvertently misplaces the information device or removes the information device from the user's body against the will of the user, the data of the information device is protected.

In particular, for example, when such an information device is used in various authentication systems, the security of the authentication data can be improved, and the security strength of the entire authentication system can be increased.

Further, since a predetermined holding time is provided between the detection of the detachment of the information device from the user and the start of the data security operation, there is a certain reason including an erroneous use error for some reason. However, if the user detaches the information device from the human body for a relatively short period of time, the user can continue using the information device by wearing the information device again without performing any specific operation. And the handling of information equipment can be improved.

Next, a second embodiment of the present invention will be described with reference to FIG.

In the second specific example and a specific example described later, the configuration of the information device main body 11 and the overall control method are the same as those of the first specific example described above. Will be omitted.

In the information device 10 of the second specific example, the attachment / detachment detecting means 13 detects whether or not the attachment member 12 of the information device 10 has been attached to a human body, thereby detecting the attachment / detachment of the information device 10. The state is determined, and the detection of the state is performed using a sensor that does not perform a mechanical operation.

The mounting member 12 of this embodiment is wound around the user's mounting site when the mounting member 12 is mounted, similarly to the above-described specific example. It is not a shape but divided into two.

The attachment / detachment detecting means 13 of the second specific example
Detects whether such a mounting member 12 has a closed ring shape in a mounted state or a split and expanded shape in an unmounted state, that is, detects whether the mounting member 12 is open or closed. In addition, the state of attachment / detachment of the information device 10 is determined.

That is, the mounting member 12 is composed of two members 12a and 12b formed of a relatively wide band having a predetermined length using a material having a predetermined flexibility. Is fixed to the information device 10 main body, a buckle-shaped connection fitting 25 is provided at one end, and a receiving portion 26 for latching the connection fitting 25 is provided at the other end. ing.

Further, the connection fitting 25 has at least
Frame-shaped fitting 25a formed with a frame width larger than the belt width

Next, the distortion sensor 31 basically
A resistance wire having a predetermined resistance value is built in, and the current / voltage value output from the resistance wire changes according to the curvature in the longitudinal direction of the wire, that is, the degree of bending.

Such a strain sensor 31 is provided with a certain length along the circumferential direction of the mounting member 12, and a detection value corresponding to a change in curvature of the outer circumference of the mounting member 12 is obtained. Like that.

Accordingly, when the information device 10 is mounted, the mounting member 12 is formed in a predetermined shape along the outer circumference of the wrist of the user, and accordingly, a predetermined detection value is obtained from the distortion sensor 31 while the non-mounting state is obtained.

2 has a shape different from the shape along the outer circumference of the wrist of the user, and similarly, a detection value different from that at the time of wearing is obtained,
It is possible to simply and accurately determine whether the device is mounted or not.

Since the curvature, that is, the sensor output value is different depending on the wrist thickness which varies depending on the user, the detected value for the normal user is recorded in advance, and this recorded value is
The accuracy of the attachment / non-attachment determination may be enhanced by comparing and determining the sensor output value actually obtained at the time of the attaching / detaching operation.

Further, a stress sensor or a tension sensor for detecting a stress state or a tension state of the mounting member 12 which changes depending on whether or not the user wears the mounting member 12 may be provided on the mounting member 12. Even if the member 12 uses a relatively elastic material such as a rubber band, for example, in addition to the above-described configuration, the same effect is achieved, and the state of the mounting member 12 is detected by these sensors. Since the location is not relatively limited, the degree of freedom in design can be improved.

That is, for example, in the configuration for detecting a change in curvature by the distortion sensor 31, the detection point of the distortion sensor 31 requires a certain length along the circumferential direction of the mounting member 12, whereas in this case, The detection location may be only one point on the mounting member 12, or a plurality of the detection locations may be provided to improve the detection accuracy and accuracy.

As described above, according to this example,
As a method for detecting the state of mounting the information device on the human body, a distortion sensor is provided on the mounting member to detect whether or not this member has a mounted shape, as in the second specific example, Problems due to mechanical switches and sensors can be avoided beforehand, durability and operation reliability can be improved, and various types can be used without restricting the mounting member itself.

That is, since the degree of freedom of the material and design of the mounting member is increased and various materials and designs can be used, the decorativeness can be enhanced and the commercial value of the information device 10 can be improved.

Similarly, it is not affected whether the mounting member always maintains the ring-shaped configuration or separates into two when not mounted. Also, the degree of freedom of these designs can be improved without being affected by the configuration of the connection metal fittings that are separately connected and the connection form.

It should be noted that the attachment / detachment detecting means 13 of each of the above-described specific examples is used.
Are not excluded from each other, and may be used in combination depending on use conditions or the like. By using a plurality of detection methods at the same time, it is possible to determine whether the information device 10 is mounted or not mounted in relation to the basic operation. Accuracy and reliability can be improved.

Further, the present invention relates to the above-mentioned portable information devices, specifically, portable devices such as watches, mobile phones, pedometers, glasses, hair bands, necklaces, earrings, rings, belts, and the like. It can be used for accessories such as tie pins.
