ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to security technology for personal information equipment in which operation and input are performed with a pen.
BACKGROUND OF THE INVENTION
There is disclosed a method of authorizing an individual in information equipment as security technology for a personal communicating device based on the conventional technology, for instance, in Japanese Patent Laid-Open Publication No. HEI 7-129512 as well as in Japanese Patent Laid-Open Publication No. HEI 6-332861.
FIG. 10
shows the method of authorizing an individual in information equipment disclosed in these publications.
In the authorizing method disclosed in the example, security management for controlling access to information in the information equipment is carried out by correlating data of inputted graphics and characters or the like or handwriting with authorization data or characteristics parameters previously stored therein.
Namely, in these types of information equipment, security control is provided by, at first, receiving data in step
91
, extracting the characteristics in step
92
, correlating the characteristics with cryptographic data or measuring a degree of similarity between the characteristics and the handwriting parameters or the like in step
93
, and further making a determination in the next step
94
as to whether each of the data is identical to the authorization or not, and releasing the access lockout and permitting access to information stored in the terminal in the next step
95
in a case where it is determined that a result of correlation is “yes”.
In this case, the data inputted in step
91
is necessary to be data for particular graphics or handwriting, and further the user is required to have the cryptographic symbol or characteristics data for the handwriting stored in the main system of the terminal. For instance, in the invention on the conventional technology and disclosed in Japanese Patent Laid-Open Publication No. HEI 7-129512, it is required to write a cryptographic symbol in the terminal once, while, in the prior invention disclosed in Japanese Patent Laid-Open Publication No. HEI 6-332861, it is necessary to input characters or the like in the terminal once to authorize the handwriting, so that the inventions can not be applied, for instance, to a case where the user wants to move or open a window in a window system at the beginning of the operation. For this reason, if the inventions are applied to equipment having a user interface with large flexibility like a pen-inputted personal information terminal device, a free session may be impeded. Also, in the operation for releasing the protection described above, completely identical data is not always inputted, so that inaccuracy is inevitably left in the determination for authorizing the cryptographic symbol or handwriting.
However, in the conventional technology as described above, a method of effecting the protected state is not disclosed, and if the protection is once released, protection-released state is continued until an operation for effecting the protected state is executed again, so that, if the user forgets activate the protected state after a session to the main system of the terminal is once finished, there is the danger that anyone can access the information, and for this reason, in a case where the method for authorizing an individual as described above is applied to the pen-inputted personal information terminal device, the information may be abused.
Also, if requirements of writing graphics and characters at the beginning of the operation whenever the user uses the main system of the terminal or of setting protection each time the user leaves the terminal are added to the operation, the user can not smoothly operate the terminal, which causes a free session impeded.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a pen-inputted personal information terminal device in which if the user owns a pen with a specific ID code, a security function can be included in such actions as owning the pen and touching a tablet with the pen, so that the user is not required to release the protection before starting use of the equipment, nor to carry out an operation for effecting the protection after use thereof, which makes it possible to solve the problems on security caused by forgetting to execute an operation for effecting the protection, and at the same time to freely operate the terminal as usual without realizing the necessity for security.
In the present invention, the pen-inputted personal information terminal device comprises a dedicated pen for transmitting thereto its preset ID code, on the other hand, the main system of the terminal stores therein the ID code of the dedicated pen, receives the ID code transmitted by the dedicated pen, and authorizes pen-touched input of various instructions for processing onto the tablet in a case where the received ID code matches the previously stored ID code of the dedicated pen, so that it is possible to prevent any unauthorized user from abusing the pen-inputted personal information terminal device even if the user does not carry out any specific operation so long as the user carries the dedicated pen with the ID code specific to the terminal with the user, and the user can operate the device without realizing the necessity of security because the user is not required to do any specific operation for authorization.
In the present invention, the pen-inputted personal information terminal device further comprises a pen accommodating section for accommodating therein a pen in the main system of the terminal, tries receiving an ID code of a pen from the pen when the pen is accommodated in the pen accommodating section, receives the ID code transmitted from a dedicated pen in a case where it is determined that the pen is the dedicated pen, makes determination as to whether the ID code from the pen can be received or not .when the pen is accommodated in the pen accommodating section, and also further makes determination, in a case where the ID code can be received from the pen, as to whether the received ID code matches the ID code of the previously stored dedicated pen or not, and authorizes pen-touched input of various instructions for processing onto the tablet in a case where the received ID code matches the ID code of the previously stored dedicated pen, so that, so long as the dedicated pen with the ID code specific to the terminal is accommodated in the pen accommodating section, operation with any other pen can always be valid, which makes it possible to improve convenience in use, and if the dedicated pen to the terminal is not accommodated in the pen accommodating section, input with any other pen other than the dedicated pen becomes basically invalid, so that the user can insure security without carrying out any specific operation and also it is possible for any unauthorized user from abusing the pen-inputted personal information terminal device.
In the present invention, the pen-inputted personal information terminal device makes determination, in a case where any of various instructions for processing is inputted by touching the tablet with the pen, as to whether the input is carried out with operation of pen-down or of pen-drag, makes determination, in a case where it is determined that the input is performed with the pen-down, as to whether an ID code can be received from the pen or not, further makes determination, in a case where the ID code could be received from the pen, as to whether the received ID code matches the previously stored ID code of the dedicated pen or not, and authorizes pen-touched input of various instructions for processing onto the tablet in a case where the received ID code matches the previously stored ID code of the dedicated pen, so that, even in a case where the dedicated pen is not accommodated in the pen accommodating section, the input can be performed in a case where pen-input on the tablet is performed with the dedicated pen to the terminal, and for this reason,
