Abstract

An information processing apparatus is constructed to include an input section which inputs information and instruction, a comparing section which compares an input operation pattern from the input section with one or a plurality of registered operation patterns which are registered in advance depending on the operation mode, and a control section which controls the operation mode to a state where the operation from the input section is impossible based on a comparison result of the comparing section.

Claims

1. An information processing apparatus comprising:

an input section which inputs information and instruction;

a comparing section which compares an input operation pattern from said input section with one or a plurality of registered operation patterns which are registered in advance, depending on the operation mode; and

a control section which controls the operation mode to a state where the operation from said input section is impossible based on a comparison result of said comparison section.

2. The information processing apparatus as claimed in claim 1, wherein said comparing section outputs a match signal if a difference between the input operation pattern from said input section and the one or plurality of registered operation patterns is within a tolerable range, and said control section controls the operation mode to the state where said operation is impossible in response to said match signal.

3. The information processing apparatus as claimed in claim 1 or 2, wherein said control section controls the operation mode to the state where said operation is impossible, and at the same time, prohibits a restart of the information processing apparatus.

4. The information processing apparatus as claimed in any of claims 1 to 3, which further comprises a notifying section which notifies the state where said operation is impossible and/or the prohibition of restart.

5. The information processing apparatus as claimed in any of claims 1 to 4, which further comprises a canceling section which cancels the state where said operation is impossible and/or the prohibition of restart.

6. The information processing apparatus as claimed in any of claims 1 to 5, which further comprises a registration part which stores the input operation pattern from said input section and automatically registers said one or plurality of registered operation patterns.

7. A computer-readable storage medium which stores a program for causing a computer to have a security function, said program causing the computer to carry out:

a comparing procedure which compares an input operation pattern with one or a plurality of registered operation patterns depending on an operation mode of the computer; and

a control procedure which controls the operation mode to a state where the input operation is impossible based on a comparison result of said comparing procedure.
