Abstract

A method and apparatus for protecting sensed content and warning a target of sensing is disclosed. A first transceiver, (e.g., a network server), includes a database which defines at least one zone in which sensing a target is not permitted. A second transceiver, (e.g., a cell phone), senses a target to obtain content and temporarily stores the content in a memory, after being encrypted. The cell phone transmits information to the network server which indicates the location of the cell phone. The network server receives the location information from the cell phone and determines whether the target was sensed in a “Do Not Disturb Zone”. If so, the network server instructs the cell phone to delete the encrypted content from the memory. Otherwise, the network server indicates to the cell phone that the temporarily stored content may be decrypted, stored in a permanent memory and used as desired.

Claims

1. A method of protecting sensed content comprising:

using a transceiver to sense a target to obtain content;

temporarily storing the content in a first memory within the transceiver;

the transceiver transmitting information indicating a location of the transceiver;

determining whether the location indicated by the information is within a zone in which sensing a target is not permitted;

if the location of the transceiver is within the zone, the transceiver receiving a first command signal instructing the transceiver to delete the content from the first memory; and

if the location of the transceiver is not within the zone, the transceiver receiving a second command signal instructing the transceiver that the content in the first memory may be used as desired.

2. The method of claim 1 further comprising comparing the location information to information in a “

Do Not Disturb Zone”

database to determine whether there is a match which indicates that use of the temporarily stored content is not permitted.

3. The method of claim 1 further comprising comparing the location information to information in a “

Do Not Disturb Zone”

database to determine whether there is not a match which indicates that use of the temporarily stored content is permitted.

4. The method of claim 1 wherein the transceiver is operated by at least one subscriber of a service provider.

5. The method of claim 1 wherein the transceiver is a wireless transmit/receive unit (WTRU).

6. The method of claim 1 further comprising:

encrypting content sensed by the transceiver before temporarily storing the content in the first memory.

7. The method of claim 1 further comprising:

in response to the transceiver receiving the second command signal, the transceiver decrypting the content stored in the first memory; and

the transceiver permanently storing the decrypted content in a second memory.

8. The method of claim 1 further comprising:

a user using a user interface of the transceiver to define the zone in which sensing a target is not permitted.

9. The method of claim 8 wherein the user selects one or more sensing devices via the user interface to obtain content associated with the target.

10. The method of claim 8 wherein the user indicate the dimensions and configuration of the zone via the user interface.

11. The method of claim 8 wherein the user selects a power save criteria via the user interface to designate how often the transceiver will transmit location information.

12. The method of claim 8 further comprising:

the user sending an email requesting that the zone be established.

13. A wireless transmit/receive unit (WTRU) for sensing and protecting sensed content, the WTRU comprising:

a sensing unit for sensing a target to obtain content;

a first memory which temporarily stores the content;

a position locator configured to generate information of a location of the WTRU;

a transmitter which generates and transmits a content verification request;

a receiver for receiving a message sent in response to the content verification request;

a content encryption/decryption unit which encrypts the content sensed by the sensing unit before temporarily storing the content in the first memory, and decrypts the content stored in the first memory if the message indicates that the stored content is authorized for use; and

a processor for initiating a process to delete the encrypted content if the message indicates that the stored content is not authorized for use.

14. The WTRU of claim 13 further comprising:

a permanent memory for storing the decrypted content if the message indicates that the content is authorized for use.

15. The WTRU of claim 13 further comprising:

a user interface used by a user of the WTRU to define a zone in which sensing a target is not permitted.

16. The WTRU of claim 15 wherein the user indicates the dimensions and configuration of the zone via the user interface.

17. The WTRU of claim 13 further comprising:

a user interface used by a user of the WTRU to select one or more sensing devices to obtain content associated with the target.

18. The WTRU of claim 13 further comprising:

a user interface used by a user of the WTRU to select a power save criteria to designate how often the WTRU will provide the location information.

19. The WTRU of claim 13 wherein the sensing unit includes a microphone for recording sounds emitted by the target.

20. The WTRU of claim 13 wherein the sensing unit includes a zoom lens for recording images of the target.

21. An integrated circuit (IC) for use in conjunction with a sensing unit which senses a target to obtain content, the IC comprising:

a first memory which temporarily stores the content;

a position locator configured to generate information of a location of the sensing unit;

a transmitter which generates and transmits a content verification request;

a receiver for receiving a message sent in response to the content verification request;

a content encryption/decryption unit which encrypts content sensed by the sensing unit before temporarily storing the content in the first memory, and decrypts the content stored in the first memory if the message indicates that the stored content is authorized for use; and

a processor for initiating a process to delete the encrypted content if the message indicates that the stored content is not authorized for use.

22. The IC of claim 21 further comprising:

a permanent memory for storing the decrypted content if the message indicates that the content is authorized for use.

23. The IC of claim 21 further comprising:

a user interface configured to define a zone in which sensing the target is not permitted.

24. The IC of claim 23 wherein the user interface is further configured to indicate the dimensions and configuration of the zone via the user interface.

25. The IC of claim 21 further comprising:

a user interface configured to select one or more sensing devices to obtain content associated with the target.

26. The IC of claim 21 further comprising:

a user interface configured to select a power save criteria to designate how often to provide location information.
