Method and system for a secure virtual keyboard
View Patent ↗Methods and systems provide a secure virtual keyboard represented as an onscreen keyboard with multiple levels of security. The secure virtual keyboard provides keys that are a combination of numerals, alphabets and special characters. Different security features provided include, but are not limited to, randomly changing the key layout, providing an option for mouse-hover input, and using a secure encrypted transmission path.
1. A method in a data processing system for a secure virtual keyboard, comprising:
displaying a virtual keyboard having keys on a display;
displaying the virtual keyboard with a different layout of the keys on a subsequent display of the virtual keyboard;
receiving an indication of a minimum time to hover a mouse pointer over a key on the virtual keyboard to activate the key;
receiving an indication of the mouse pointer being over the key;
determining if the mouse pointer is over the key longer than the indicated minimum time to hover;
entering the key if it is determined that the mouse pointer is over the key longer than the indicated minimum time to hover;
encrypting a transmission to a device communicating with the virtual keyboard; and
transmitting the encrypted transmission to the device communicating with the virtual keyboard.
2. The method of claim 1 , wherein encrypting the transmission further comprises encrypting the transmission with a public key.
3. The method of claim 1 , further comprising:
receiving the encrypted transmission; and
decrypting the received encrypted transmission.
4. The method of claim 3 , wherein the transmission is encrypted in a symmetric encryption protocol.
5. The method of claim 3 , further comprising decrypting the received encrypted transmission with a private key.
6. The method of claim 5 , wherein the transmission is encrypted in one of (1) the RSA protocol, and (2) the DH protocol.
7. The method of claim 1 , wherein displaying the virtual keyboard is initiated by a USB device.
8. The method of claim 1 , wherein the device generating the virtual keyboard is a USB device.
9. The method of claim 1 , wherein the device generating the virtual keyboard is a website server.
10. The method of claim 1 , further comprising changing the minimum time to hover the mouse pointer over a key on the virtual keyboard to activate the key.
11. The method of claim 1 , wherein entering the key further comprises entering the key in a password window.
12. The method of claim 1 , further comprising applying an authentication code to the transmission.
13. The method of claim 12 , wherein the authentication code is one of: (1) a hash value and (2) a MAC.
14. A data processing system for a secure virtual keyboard, comprising:
a display configured to display a virtual keyboard;
a mouse configured to control a mouse pointer on the display;
a memory configured to store instructions to instruct a processor to:
display the virtual keyboard having keys on the display;
display the virtual keyboard with a different layout of the keys on a subsequent display of the virtual keyboard;
receive an indication of a minimum time to hover the mouse pointer over a key on the virtual keyboard to activate the key;
receive an indication of the mouse pointer being over the key;
determine if the mouse pointer is over the key longer than the indicated minimum time to hover;
enter the key if it is determined that the mouse pointer is over the key longer than the indicated minimum time to hover;
encrypt a transmission to a device communicating with the virtual keyboard; and
transmit the encrypted transmission to the device communicating with the virtual keyboard; and
a processor to execute the instructions.
15. The data processing system of claim 14 , wherein the instructions further comprise encrypting the transmission with a public key.
16. The data processing system of claim 14 , wherein the transmission is encrypted in one of: (1) the RSA protocol, and (2) the DH protocol.
17. The data processing system of claim 14 , wherein the transmission is encrypted in a symmetric encryption protocol.
18. The data processing system of claim 14 , further comprising a USB device configured to initiate the displaying of the virtual keyboard.
19. The data processing system of claim 18 , wherein the device generating the virtual keyboard is the USB device.
20. The data processing system of claim 14 , wherein the device generating the virtual keyboard is a website server.
21. The data processing system of claim 14 , wherein the instructions further comprise changing the minimum time to hover the mouse pointer over a key on the virtual keyboard to activate the key.
22. The data processing system of claim 14 , further comprising a password window configured to receive the entering of the key.
23. The data processing system of claim 14 , further comprising applying an authentication code to the transmission.
24. The data processing system of claim 23 , wherein the authentication code is one of: (1) a hash value and (2) a MAC.
