Patent ID: 8302156

Claim:
A method for securing computer information, wherein a computer will enter to an encoding status when a user is away from a connection device with a sensor to prevent other user from using said computer; and when said sensor positions within a preset range of said connection device, said computer will decode for user to operate; the method comprising: (A) electrically connecting said connection device to said computer; (B) initializing said connection device if it is needed, and proceed to step (C) otherwise proceed to step (D); (C) running an initialization; (D) said connection device verifying whether said sensor has a corresponding second identification code with said connection device in a preset period of time, wherein if it is not, proceed to step (E); otherwise, proceeds to step (F) if it is valid; (E) connection device controlling said computer for staying in encoding status; and (F) connection device transmitting a first identification code to said computer for decoding, said first identification code comprises a user name and a password for connecting said predetermined computer and said connection device; said second identification code comprises a connection code and a channel for connecting said connection device and sensor; Step (C) further comprising the steps of (a) a user pressing key of said connection device is determined, wherein if it is determined that the key is pressed, proceed to step (d), otherwise proceed to step (b). (b) a light emitting element of said connection device generating light; (c) said connection device notifying said computer of invalid status of said sensor and proceed to (i); (d) said connection device detecting whether said sensor is plugged into said connection device, if said sensor is plugged in, proceed to step (e), otherwise return to step (d); (e) connection device detecting whether a button of said sensor is being pressed, wherein if said sensor is pressed, proceed to step (t), otherwise proceed to step (e); (t) generating said second identification code between said connection device and said sensor; (g) storing said second identification code generating between said connection device and said sensor; (h) shutting down a light emitting element of said connection device and a light emitting unit of said sensor; and (i) ending step (C).
