Abstract

PURPOSE:To judge whether data is correct or not by storing input data from an input device of a computer including time elements and comparing it with preliminarily registered data. CONSTITUTION:When input of a password code is completed, a program which discriminates whether it coincides with preliminarily registered data or not is started to compare the password code with the preliminarily registered code. If they coincide with each other, the input time of each code and the period between code inputs are compared. In this case, a coefficient is calculated which equalizes the first code input time to the first registered code input time. Data of the code input time is multiplied by this coefficient, and the result is compared with a registered time, and coincidence between input data and registered data is judged if the comparison result is within an allowable range preliminarily set on the decision program.

Description

Detailed Description of the Invention V. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a data processing device for a computer system, and more particularly to a data processing device that performs input and judgment processing suitable for data security.

[Conventional technology]

Traditional computer input processing simply writes data from an input device into memory in the vehicle.

However, insufficient consideration was given to data security when entering information that could be used by others, such as a PIN code.

[Problems to be solved by the invention] The above-mentioned conventional technology does not give sufficient consideration to data security, and when entering secret data such as a PIN number, simply memorizing the number can cause other people to do the same. There was a problem that the operation of

An object of the present invention is to provide a data processing device that can prevent leakage of important data.

[Means for solving problems]

The above object is achieved by a means that stores input data including time elements from a computer input device and compares it with pre-registered data to determine whether the data is correct or incorrect.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

FIG. 3 is a computer system configuration diagram showing an embodiment of the data processing apparatus according to the present invention. This system is composed of a keyboard (input device) 1, a CPU (central processing I&!) 2, and a memory (storage device) 3.

FIG. 1(α) is a flowchart of input processing by the input program of FIG. Further, FIG. 2(a) is an explanatory diagram of the memory storage state of the input code of FIG. 3. Figure 1 (
The operation of the input processing shown in FIG. 3 will be explained with reference to α) and FIG. 2(α).

In order to be able to call up a particular file, the operator keys in a password from the keyboard 1.

Once the first code is keyed in.

The data input program of CP (J 2) starts.The data input program stores the keyed-in data in the memory 3 (step 1α) and the time that the code is input into the primary memory area (the operator presses the key). When the first code key-in is completed, the time until the next code is input is counted and stored in the next memory area (step 3α). Then, when the next code is keyed in, the keyed-in data is stored in the next memory area, and the time that the code was entered is stored in the first area. Repeat until.

FIG. 1(A) is a flowchart of the discrimination processing by the discrimination program of FIG. Further, FIG. 2 Ch) is an explanatory diagram of the memory state of the determination process in FIG. 3. The operation of the discrimination process shown in FIG. 3 will be explained with reference to FIG. 1(h) and FIG. 2(A).

When the input of the PIN code is completed, a program is activated to determine whether the data is the same as the data registered in advance. The determination program compares the password code to see if it is the same as a previously registered code (step 1h). If they are the same, the time and code when each code was entered;
- Compare the time between modes. At this time, first, a coefficient is calculated to make the time during which the first code was input equal to the registered input time of the first code (step 2.6). Next, multiply the input time data of each code by this coefficient and compare it with the registered time (step 3b). If it is within the tolerance range set in advance on the judgment program, it is the same as the registered data. I judge that. Also, if it is outside the allowable range, error processing is performed.

According to this embodiment, it is better to form a code that includes a 1% time pattern to prevent leakage of the confidentiality of a specific file, compared to performing a process such as calling a specific file using only input code data from the keyboard. is effective.

For example, if the time pattern to be input is the rhythm of the lyrics of a song that the operator is familiar with, a one-hour pattern can be easily input.

[Effects of the Invention] According to the present invention, important data cannot be called up using only input data from a computer input device, so that leakage of important data can be prevented.
