Abstract

(57) [Summary] [PROBLEMS] To provide a computer device which eliminates troublesome input of an ID number and a password and can take a high level of security measure. SOLUTION: When trying to use an application which is the computer device 1, a user first causes a fingerprint reading means 2 to read his / her own fingerprint. As a result, the fingerprint collating means 17 refers to the fingerprint database 15 and extracts information on whether the corresponding fingerprint is registered and information on the management authority of the person having the registered fingerprint. Then, when an input operation is performed by the touch panel 3, the display screen control unit 18 displays the operation content within a range permitted according to the extracted management authority on the display unit 3, and receives an input from the touch panel. In this way, the user only has to read his / her fingerprint, and thereafter, by touching the screen displayed by the display means, only operations within his / her administrative authority can be performed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a computer device.

[0002]

2. Description of the Related Art Generally, in a computer device used for business, when a certain application program is used, a function that can be used with the authority of a user in order to prevent unspecified persons from freely falsifying input data. It is necessary to impose restrictions on the range, and security measures are often taken to input an ID number and a password before using the application.

[0003]

However, for example, in the case of a small computer device such as a touch panel type display which does not have a keyboard, it is not possible to input an ID number and a password using the keyboard. The same contents are displayed to all users who perform the operation, and input operations can be performed from the touch panel without distinguishing the users. For this reason, the above-described security measures cannot be taken, and in particular, a serious operation such as changing a set value of the process control can be operated by any user carrying the computer device regardless of the management authority. It is a situation that does not get.

[0004] In order to avoid this, and to limit the range in which the input operation can be performed in accordance with the administrative authority, even if the above-mentioned small computer device is used to input an ID number or a password, a virtual keyboard is displayed on the display unit. It is conceivable to adopt a configuration in which a touch operation is performed by a touch panel. However, if the size of a portable computer is reduced to a so-called PDA (Personal Digital Assistant) or smaller, which is assumed to be used for input operation with the other hand while holding it with one hand, the display area is reduced. In addition, there is a problem that input errors are likely to occur because the displayed characters are small, and the usability is deteriorated.

On the other hand, if the number of displayed characters is reduced, individual characters can be displayed larger, but in this case, the password is limited to a simple one because of the reduced number of displayed characters. There is a concern that they will be spotted.

On the other hand, if the user releases the input operation of the ID number and the password and performs the touch operation, the fingerprint of the user is read at that time, and only when the fingerprint of the user is verified as a valid user, the fingerprint is checked. A computer device that receives an input by a touch operation is also described in, for example, Japanese Utility Model Laid-Open No. 3-113436. However, in the case of this conventional example, the configuration is such that a fingerprint is collated each time a user inputs an operation, and whether or not the operation input is accepted is determined. It does not change the screen displayed on the display means according to the management authority of.

[0007] Therefore, the display content of the screen for touch operation is uniform even if the user is different, and even a button or an icon displayed on the screen is accepted when an unauthorized user touches it. On the contrary, there is a problem that the user is confused.

The present invention has been made in view of such conventional problems, and reads a user's fingerprint and displays an operation screen in a range of contents in which operation is permitted according to the user's management authority. It is another object of the present invention to provide a computer device that accepts a touch operation input, eliminates troublesome input of an ID number and a password, and can take a high level of security measures.

[0009]

According to a first aspect of the present invention, there is provided a computer device for displaying various information, a touch panel provided on the display device for performing a touch input operation, and a fingerprint of a user. Fingerprint reading means for reading the fingerprint data of a plurality of persons, and a fingerprint database in which data comparing the management authority of each person is registered, and comparing the fingerprint read by the fingerprint reading means with the data of the fingerprint database. A fingerprint collation means for judging management authority, and a screen for restricting an input operation screen to be displayed on the display means for a touch input operation by the touch panel to one according to the level of management authority judged by the fingerprint collation means. Display control means.

In the computer device according to the first aspect of the present invention,
When trying to use the application program which is the computer device, the user first causes the fingerprint reading means to read his / her fingerprint. Thus, the fingerprint collating unit refers to the fingerprint database to extract information on whether the corresponding fingerprint is registered and information on the management authority of the person having the registered fingerprint. This allows
When an input operation is subsequently performed on the touch panel, the display screen control unit displays an operation content in an allowable range according to the extracted management authority level on the display unit as an operation screen, and accepts input from the touch panel.

This eliminates the need for the user to enter an ID number or a password, and allows the fingerprint reader to read his / her own fingerprint. By performing a touch operation on the screen to be displayed, an operation within its own management authority can be performed.
