Abstract

A method for maintaining security of a retail terminal having a docking station and a portable computer includes the computer-implemented steps of receiving an unlocking attempt to unlock the portable computer from the docking station; determining whether the unlocking attempt is valid; and unlocking the portable computer from the docking station if the unlocking attempt is valid. A multi-functional retail terminal is also disclosed.

Claims

1. A method for maintaining security of a computer terminal having a docking station and a portable computer, comprising the computer-implemented steps of:

generating electronic information in response to an unlocking attempt to unlock the portable computer from the docking station;

storing a plurality of values that are indicative of valid unlocking attempts;

determining whether the unlocking attempt is valid based upon the electronic information and the plurality of values;

unlocking the portable computer from the docking station in response to the determining step determining that the unlocking attempt is valid; and

preventing unlocking of the portable computer from the docking station in response to the determining step determining that the unlocking attempt is invalid.

2. The method of claim 1, further including the computer-implemented step of:

updating a security log in response to actions relating to the security of the portable computer.

3. The method of claim 1, wherein:

the generating step includes the computer-implemented step of receiving the unlocking attempt from a user,

the plurality of values includes a user rights table, and

the step of determining whether the unlocking attempt is valid includes the computer-implemented step of checking the user rights table to determine whether the user has a right to unlock the portable computer from the docking station.

4. The method of claim 1, further including the computer-implemented step of:

disabling the portable computer after a predetermined number of successive invalid unlocking attempts.

5. The method of claim 1, further including the computer-implemented step of:

disabling the portable computer if the portable computer is removed from the docking station prior to unlocking the portable computer from the docking station.

6. The method of claim 1, further including the computer-implemented step of:

undocking the portable computer by urging the portable computer outwardly from the docking station after the step of unlocking the portable computer from the docking station; and

updating a security log in response to the undocking step.

7. The method of claim 1, further including the computer-implemented steps of:

receiving the portable computer into the docking station;

detecting the presence of the portable computer when the portable computer is received in the docking station; and

locking the portable computer to the docking station when the portable computer is detected.

8. The method of claim 7, further including the computer-implemented step of:

docking the portable computer to the docking station by urging the portable computer into operative engagement with the docking station before locking the portable computer to the docking station.

9. The method of claim 7, further including the computer-implemented steps of:

receiving a locking attempt to lock the portable computer to the docking station; and

locking the portable computer to the docking station.

10. The method of claim 1, wherein said receiving step includes the step of:

receiving said electronic information from a data input device that is selected from a group of data input devices consisting of a keyboard, a mouse, a touch screen, a biometric device, a magnetic strip reader, a bar code reader, and a voice recognition system.

11. A multi-functional retail terminal, comprising:

a docking station;

a portable computer;

a coupler configured to detachably couple said portable computer to said docking station; and

a locking mechanism configured to unlock said portable device from said docking station in response to determining that an unlocking attempt to unlock said portable computer from said docking station is valid,

wherein said docking station includes a retail peripheral, and said portable computer and said docking station are configured to perform a point of sale transaction and general purpose computing, and

wherein said docking station and said portable computer are configured to (i) generate electronic information in response to said unlocking attempt, (ii) determine whether said unlocking attempt is valid based upon said electronic information and a plurality of stored values that are indicative of valid unlocking attempts, and (iii) prevent unlocking of said portable computer from said docking station in response to determining that said unlocking attempt is invalid.

12. The multi-functional retail terminal of claim 11, wherein:

said docking station and said portable device are configured to update a security log in response to actions relating to the security of said portable computer.

13. The multi-functional retail terminal of claim 11, wherein said portable computer comprises:

a disabling mechanism which when activated disables said portable computer.

14. The multi-functional retail terminal of claim 13, wherein said disabling mechanism is configured to disable said portable computer if said portable computer is de-coupled from said docking station prior to de-activating the locking mechanism.

15. The multi-functional retail terminal of claim 11, further comprising a data input device that is selected from a group of data input devices consisting of a keyboard, a mouse, a touch screen, a biometric device, a magnetic strip reader, a bar code reader, and a voice recognition system, wherein:

said portable computer and said docking station are further configured to receive said electronic information from said data input device.

16. A retail network, comprising:

a network server;

a docking station;

a portable computer;

a coupler configured to detachably couple said portable computer to said docking station;

a network interface configured to provide a communications link between said network server and said docking station; and

a locking mechanism configured to unlock said portable device from said docking station in response to determining that an unlocking attempt to unlock said portable computer from said docking station is valid,

wherein said docking station includes a retail peripheral, and said portable computer and said docking station are configured to perform a point of sale transaction and general purpose computing,

wherein a plurality of values that are indicative of valid unlocking attempts are stored in said network server, and

wherein said docking station and said portable computer are configured to (a) generate electronic information in response to said unlocking attempt, (b) determine whether said unlocking attempt is valid based upon said electronic information and said plurality of values stored in said network server, and (c) prevent unlocking of said portable computer from said docking station in response to determining that said unlocking attempt is invalid.

17. The retail network of claim 16, wherein:

said network server, said docking station, and said portable device are configured to update a security log in response to actions relating to the security of said portable computer.

18. The retail network of claim 17, wherein said portable computer comprises:

a disabling mechanism which when activated disables said portable computer.

19. The retail network of claim 18, wherein said disabling mechanism is configured to disable said portable computer if said portable computer is de-coupled from said docking station prior to de-activating the locking mechanism.

20. The retail network of claim 19, wherein said portable computer further comprises:

a wire-less network interface configured to provide a wire-less communications link between said portable computer and said network server;

wherein said disabling mechanism is configured to activate in response to a disabling signal; and

wherein said network server is configured to send said disabling signal to said portable computer via said wire-less network interface when said network server determines a security violation involving said portable computer has occurred.

21. The retail network of claim 16, further comprising a data input device that is selected from a group of data input devices consisting of a keyboard, a mouse, a touch screen, a biometric device, a magnetic strip reader, a bar code reader, and a voice recognition system, wherein:

said portable computer and said docking station are further configured to receive said electronic information from said data input device.
