Abstract

PURPOSE:To provide the information processor which senses affection by a virus. CONSTITUTION:A detecting means 2 compares input data 7 buffered in a buffer means 1 with pattern data 8 stored in a virus pattern storage means 3 and once the detecting means 2 detects the virus from matching between the input data 7 and pattern data 8, a control means 5 sends an alarm signal 9 according to the detection result and also stops the operation of an interface means 4, thereby stopping sending the input data 7 to a CPU 6. When the input data 7 and pattern data 8 are discrepant and the detecting means 2 detects no affection by a computer virus, the interface means 4 operates under the control of the control means 5 and the CPU 6 processes the input data 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing device,
In particular, the present invention relates to an information processing device including a computer virus detecting means.

[0002]

2. Description of the Related Art A conventional (not shown) information processing apparatus has no countermeasure against a computer virus, and therefore, when data is input, it may be infected by a computer virus without the user's knowledge.

Further, in the conventional information processing apparatus, it is necessary for the user to regularly execute a vaccine program for computer viruses to check whether or not the user is infected.

[0004]

When a conventional information processing apparatus is used to input and output data, whether a computer virus lurks in the data will be accepted by the user without any notice and the user will be affected by the computer virus. Or, there was a problem that it took time to check the infection by the vaccine program.

Therefore, an object of the present invention is to provide an information processing apparatus capable of detecting the invasion of a computer virus.

[0006]

In order to solve the above-mentioned problems, an information processing apparatus of the present invention receives a buffer means for buffering input data, and receives and outputs the input data buffered by this buffer means. Interface means, CPU for processing input data output from the interface means, virus pattern storage means for storing pattern data of a computer virus that destroys a program for the CPU to perform processing, and virus pattern storage means Detecting means for detecting a computer virus by comparing the pattern data stored in the input data with the input data, and controlling the operation of the interface means when the input data and the pattern data match with each other by the detecting means. And sends a warning signal to the CPU, When the above input data and the pattern data do not coincide with serial detection means, characterized by comprising a control means for controlling to operate the interface unit.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an information processing apparatus according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an information processing apparatus according to an embodiment of the present invention.

An information processing apparatus according to one embodiment of the present invention is
As shown in FIG. 1, buffer means 1 for buffering input data 7 and interface means 4 for receiving and outputting the input data 7 buffered by the buffer means 1.
And a CPU 6 for processing the input data 7 output from the interface means 4, a virus pattern storage means 3 for storing pattern data 8 of a computer virus that destroys a program for the CPU 6 to perform processing, and the virus pattern. The detection means 2 for detecting a computer virus by comparing the pattern data 8 stored in the storage means 3 with the input data 7 and the interface means 4 when the input data 7 and the pattern data 8 match with each other in the detection means 2. And a control means 5 for controlling the interface means 4 to operate when the input data 7 and the pattern data 8 do not match in the detection means 2. To be done.

Further, in the virus pattern storage means 3,
All currently known virus patterns are registered, and the patterns are stored when the viruses are serially transferred, in parallel, and when they are further compressed.

The operation of the information processing apparatus according to the embodiment of the present invention detects the input data 7 buffered in the buffer means 1 and the pattern data 8 stored in the virus pattern storage means 3, as shown in FIG. When the detection means 2 detects a computer virus due to the comparison by the means 2 and the input data 7 and the pattern data 8 match, the control means 5 sends an alarm signal 9 to the CPU 6 according to the detection result.
Moreover, the operation of the interface means 4 is stopped and the CPU 6
The transmission of the input data 7 to is stopped.

On the other hand, when the input data 7 and the pattern data 8 do not match and the detection means 2 detects that there is no computer virus, the control means 5 controls the input data 7 buffered by the buffer means 1 to be the interface means. Sent to the CPU 6 via
6 processes the input data 7.

[0013]

As described above, according to the information processing apparatus of the present invention, when inputting data, the user can detect the invasion of the computer virus by an alarm without getting nervous about the computer virus. There is an effect that it can be realized without destroying various data and without changing the specifications of the conventional interface.
