Abstract

Disclosed is a keyboard-video-mouse switch capable of detecting keyword input and recording video data from a computer and keyboard input data from a console and method thereof. The keyboard-video-mouse switch includes a keyword filter and a capture unit. The keyword filter detects whether a predetermined keyword is inputted from the console into the computer and the capture unit records video data if the predetermined keyword is detected. Moreover, the capture unit may record keyboard input data for a complete monitor. The keyboard-video-mouse switch of the present invention further includes an alarm and a keyword database. The alarm will alarm an administrator when the predetermined keyword is detected. The keyword database stores data of keystroke combinations, which is defined as predetermined keyword data for at least one input method.

Claims

1. A keyboard-video-mouse switch coupled with a plurality of computers and a console, the system comprising:

a keyword filter, detecting whether a predetermined keyword is inputted from the console into one of the computers; and

a capture unit, recording video data from the one of the computers if the predetermined keyword is detected.

2. The keyboard-video-mouse switch of claim 1, further comprises an alarm, alarming an administrator if the predetermined keyword is detected.

3. The keyboard-video-mouse switch of claim 1, further comprising a keyword database, storing data of at least one keystroke combination, defined as predetermined keyword data for at least one input method.

4. The keyboard-video-mouse switch of claim 3, wherein the input method is selected from a group consisting of input method in English, Phonetic input method in Traditional Chinese, Hanzi keyboard input method in Traditional Chinese, Tsang-Jye input method in Traditional Chinese, Hanzi keyboard input method in Simplified Chinese, Roma-ji input method in Japanese, hand-write input method and voice input method.

5. The keyboard-video-mouse switch of claim 3, wherein the keyword filter detects the predetermined keyword by comparing keyboard input data from the console with the predetermined keyword data stored in the keyword database.

6. The keyboard-video-mouse switch of claim 1, wherein the capture unit further records keyboard input data from the console.

7. The keyboard-video-mouse switch of claim 1, further comprising a storage device, storing the video data from the computers.

8. The keyboard-video-mouse switch of claim 7, wherein the storage device is a memory in the keyboard-video-mouse switch.

9. The keyboard-video-mouse switch of claim 7, wherein the storage device is coupled to the keyboard-video-mouse switch via a network.

10. The keyboard-video-mouse switch of claim 7, wherein the capture unit further records keyboard input data from the console.

11. The keyboard-video-mouse switch of claim 10, wherein the storage device is employed to store the video data and the keyboard input data.

12. A keyboard-video-mouse switch coupled with a plurality of computers and a console, the keyboard-video-mouse switch comprising:

a keyword filter, detecting whether a predetermined keyword is inputted from the console into one of the computers; and

an alarm, alarming an administrator if the predetermined keyword is detected.

13. The keyboard-video-mouse switch of claim 12, further comprising a keyword database, storing data of at least one keystroke combination, defined as predetermined keyword data for at least one input method.

14. The keyboard-video-mouse switch of claim 13, wherein the input method is selected from a group consisting of input method in English, Phonetic input method in Traditional Chinese, Hanzi keyboard input method in Traditional Chinese, Tsang-Jye input method in Traditional Chinese, Hanzi keyboard input method in Simplified Chinese, Roma-ji input method in Japanese, hand-write input method and voice input method.

15. The keyboard-video-mouse switch of claim 13, wherein the keyword filter detects the predetermined keyword by comparing keyboard input data from the console with the predetermined keyword data stored in the keyword database.

16. The keyboard-video-mouse switch of claim 12, further comprises a capture unit, recording video data from the one of the computers if the predetermined keyword is detected.

17. The keyboard-video-mouse switch of claim 16, further comprising a storage device, storing the video data from the one of the computers.

18. The keyboard-video-mouse switch of claim 17, wherein the storage device is a memory in the keyboard-video-mouse switch.

19. The keyboard-video-mouse switch of claim 17, wherein the storage device is coupled to the keyboard-video-mouse switch via a network.

20. The keyboard-video-mouse switch of claim 16, wherein the capture unit further records keyboard input data from the console.

21. The keyboard-video-mouse switch of claim 20, wherein the storage device is employed to store the video data and the keyboard input data.

22. A method capable of detecting keyword input for a keyboard-video-mouse switch coupling a plurality of computers to a console, the method comprising steps of:

detecting whether a predetermined keyword is inputted from the console into one of the computers by a keyword filter; and

recording video data from the one of the computers by a capture unit if the predetermined keyword is detected.

23. The method of claim 22, further comprising a step of storing the video data after the recording step.

24. The method of claim 22, further comprising a step of alarming an administrator after the recording step.

25. The method of claim 22, further recording keyboard input data from the console during the step of recording the video data.

26. The method of claim 22, wherein the keyword filter further comprises a keyword database, storing data of at least one keystroke combination, defined as predetermined keyword data.

27. The method of claim 26, further comprising a step of comparing keyboard input data from the console with the predetermined keyword data in the keyword database before the detecting step.
