The disassembly / damage detecting means 120 uses a plurality of spring sensors disposed at the coupling portion of the case, and the key 116 has a memory chip having 256 bits or more, and a password is stored in the memory chip. It is.

The input means 102 is composed of a keyboard and a mouse.

Next, the operation and effects of the computer equipped with the security device according to the embodiment of the present invention configured as described above will be described.

First, when the user (owner) of the computer touches the key 116 storing the user's information (password) on the key contact portion 118a of the key reading means 118 installed on the computer main body, the key reading means ( In 118, it is determined whether the password (including the password) of the user stored in the key 116 is the same as the password stored in the key reading means 118 in advance, and if it is the same, the signal is converted into a micro signal. Output to the processor 100, at which time the computer is initialized to an operational state.

In other words, the microprocessor 100 receives a signal output from the key reading means 118 and outputs a beep sound control signal so that the beep sound of a specific sound is output from the alarm sound generating means 128 once. The microprocessor 100 in the power supply 122 according to the operation of the power supply control means 124 by outputting a signal to the power supply control means 124 by outputting the beep sound to the generating means 128 The microprocessor 100 supplies power to each component, that is, each component.

Next, when the user inputs information (for example, Internet search information or typing information when using a word processor) using a keyboard, a mouse, or the like of the input means 102, the microprocessor 100 reads the ROM ( The hard disk driver 104 and the floppy disk driver may be driven according to the order in which the hard disk driver 104 is driven to retrieve information through the Internet or used as a word processor and operated according to an executable program stored in 108. 112 is stored in the RAM 116 and the retrieved information or the typing information is input to the display means 114.

At this time, the microprocessor 100 outputs an alarm sound generating control signal to the alarm sound generating means 128 for the operation time (2 to 12 hours) of the backup battery 110 in the alarm sound generating means 128. At the same time as outputting the alarm sound, the microprocessor 100 outputs an information deletion control signal to the information deletion means 130 and outputs an information deletion signal from the information deletion means 130 to the hard disk driver 104. In addition to deleting the information stored in the memory device, a high-voltage or higher operating power is applied to main circuits (e.g., a hard disk driver, a RAM, a ROM, etc.). Information stored at 114 is prevented from leaking to others.

On the other hand, when the user (owner) of the computer touches the key contact portion 118a of the key reading means 118 installed in the computer main body, the key 116 storing the user's information (password) is read. If the pass word stored in the key 116 at 118 is not the same as the pass word previously stored in the key reading means 118, the signal is output to the microprocessor 100, and the microprocessor 100 receives a signal output from the key reading means 118 and outputs a beep sound control signal so that the beep sound of a specific sound is output 2 to 5 times from the alarm sound generating means 128 ( 128) to output an alarm beep. In this case, power is not applied to the microprocessor 100 from the power supply 122.

In other words, if the computer of the present invention does not contact the key contact portion 118a with the key 116 to which the user's password is input, power cannot be applied and cannot be operated.

Even when the user wants to move or disassemble the computer body to another place, the alarm sound generating means only has to touch the key contact portion 118a of the key reading means 118 that the user (computer owner) carries. 128) no sirens or alarms are output.

In the above description, the present invention has been described with reference to a note book computer and a laptop computer, but the present invention is not limited thereto and may be applied to a general general computer such as a desk type. Of course.
