Abstract

System and method for securing a personal device that includes a device core and a peripheral device from unauthorized access or operation. The system comprises an isolated switch, included fully or partially within an envelope of the personal device. The isolated switch cannot be affected in its operation by either the device core or the peripheral device. The switch may be operated by an authorized user of the personal device either preemptively or in response to a detected threat. In some embodiments, the isolated switch includes an isolated controller which can send one or more signals to the peripheral device and/or part of peripheral device. In some embodiments, the isolated switch includes an isolated internal component and an isolated external component, both required to work together to trigger the isolated switch operation. In some embodiments, the isolated switch includes an isolated disconnector for connecting and disconnecting the device core from part of the peripheral device.

Claims

1. A system for securing a personal device that includes a device core and at least one peripheral device from unauthorized access or operation, comprising an internal isolated switch having operating functions that cannot be affected by either the personal device core or by the at least one peripheral device, wherein the isolated switch includes an isolated controller which can send a signal to the at least one peripheral device but which cannot be operated or affected by the personal device, the isolated controller thereby being capable of affecting operation of the at least one peripheral device.

2. The system of claim 1, wherein the isolated switch includes an isolated disconnector for connecting and disconnecting the device core from the at least one peripheral device.

3. The system of claim 1, wherein the isolated switch includes an isolated disconnector for connecting and disconnecting the device core from a part of the at least one peripheral device.

4. The system of claim 3, wherein the at least one peripheral device includes a plurality of peripheral devices and wherein the isolated disconnector can disconnect and connect any subset selected from the group consisting of a subset of the plurality of peripheral devices, a subset of parts of the plurality of peripheral devices and a subset of a mixture of some peripheral devices and parts of other peripheral devices of the plurality of peripheral devices.

5. The system of claim 1, wherein the isolated switch includes an isolated internal component and an isolated external component and wherein the isolated internal and external components trigger together the isolated switch operation.

6. The system of claim 1, wherein the at least one peripheral device includes a user input component and wherein the isolated switch includes an isolated user input logic module for reading user inputs.

7. The system of claim 1, wherein the personal device is selected from the group consisting of a mobile phone, an IP-phone, a pocket PC, a PDA, a laptop computer, a desktop computer and a network switch.

8. The system of claim 1, wherein the internal isolated switch is an electronic/electrical switch separated electrically from elements or components of the personal device.

9. The system of claim 1, wherein the internal isolated switch is a combination of a mechanical switch and an electronic/electrical switch without an electrically operated bypass and separated electrically from elements or components of the personal device.

10. The system of claim 1, wherein the isolated switch includes an input mode indicator for providing a visual indication of an internal isolated switch state.

19. The system of claim 2, wherein the isolated switch includes an isolated internal component and an isolated external component and wherein the isolated internal and external components trigger together the isolated switch operation.

20. The system of claim 3, wherein the isolated switch includes an isolated internal component and an isolated external component and wherein the isolated internal and external components trigger together the isolated switch operation.

11. A system for securing a personal device that includes a device core and at least one peripheral device from unauthorized access or operation, comprising an internal isolated switch having operating functions that cannot be affected by either the personal device core or by the at least one peripheral device, wherein the isolated switch includes an isolated disconnector for connecting and disconnecting the device core from any part of the at least one peripheral device.

12. The system of claim 11, wherein the at least one peripheral device includes a plurality of peripheral devices and wherein the isolated disconnector can disconnect and connect any subset selected from the group consisting of a subset of the plurality of peripheral devices, a subset of parts of the plurality of peripheral devices and a subset of a mixture of some peripheral devices and parts of other peripheral devices of the plurality of peripheral devices.

13. The system of claim 11, wherein the at least one peripheral device includes a user input component and wherein the isolated switch includes an isolated user input logic module for reading user inputs.

14. The system of claim 11, wherein the isolated switch includes an input mode indicator for providing a visual indication of the internal isolated switch state.

15. The system of claim 11, wherein the personal device is selected from the group consisting of a mobile phone, an IP-phone, a pocket PC, a PDA, a laptop computer, a desktop computer and a network switch.

16. A system for securing a personal device that includes a device core and at least one peripheral device from unauthorized access or operation, comprising an internal isolated switch having operating functions that cannot be affected by either the personal device core or by the at least one peripheral device, wherein the isolated switch includes an isolated internal component and an isolated external component and wherein the isolated internal and external components trigger together the isolated switch operation.

17. The system of claim 16, wherein the isolated switch includes an isolated disconnector for connecting and disconnecting the device core from the at least one peripheral device.

18. The system of claim 16, wherein the isolated switch includes an isolated disconnector for connecting and disconnecting the device core from a part of the at least one peripheral device.
