Abstract

Data received at, or created on, a device may be tagged as corporate dependent upon a service over which the data is received or an application in which the data is created. When a user attempts to insert tagged data into a data item that is to be transmitted by the device, the insertion may be prevented. Similarly, the transmission of tagged data may be restricted to only occur on a secure service.

Claims

1. A method of facilitating data protection, said method comprising:

receiving an instruction to insert data into a data item;

determining that a first service has been selected for transmission of said data item;

determining that said data is associated with a second service; and

preventing insertion of said data into said data item.

2. The method of claim 1 further comprising determining that said data is associated with said second service by determining that said data is associated with an identifier of said second service.

3. The method of claim 2 wherein said identifier of said second service comprises a globally unique identifier.

4. The method of claim 3 wherein said identifier of said second service comprises an e-mail address.

5. The method of claim 1 further comprising controlling a display to present a dialog indicating that insertion of said data into said data item has been prevented.

6. The method of claim 1 wherein said first service comprises a Short Messaging Service.

7. The method of claim 1 wherein said first service comprises a Multimedia Messaging Service.

8. The method of claim 1 wherein said first service comprises an e-mail service.

9. The method of claim 1 wherein said first service comprises an instant messaging service.

10. The method of claim 1 wherein said data item comprises an e-mail message.

11. The method of claim 1 wherein said data item comprises a calendar event invitation.

12. The method of claim 1 wherein said data item comprises an address book entry.

13. The method of claim 1 wherein said determining that said first service has been selected for transmission of said data item comprises determining that said second service is unavailable to be selected for transmission of said data item.

14. The method of claim 1 wherein said determining that said first service has been selected for transmission of said data item comprises determining that a service has been selected for transmission of said data item.

15. A mobile communication device comprising:

a communication subsystem;

a processing device adapted to;

receive an instruction to insert data into a data item;

determine that a first service has been selected for transmission of said data item using said communication subsystem;

determine that said data is associated with a second service; and

prevent insertion of said data into said data item.

16. A computer-readable medium containing computer-executable instructions that, when performed by a processor, cause said processor to:

receive an instruction to insert data into a data item;

determine that a first service has been selected for transmission of said data item;

determine that said data is associated with a second service; and

prevent insertion of said data into said data item.

17. A method of facilitating data protection, said method comprising:

receiving an instruction to transmit a data item;

determining that a first service has been selected for transmission of said data item;

determining that a portion of said data item is associated with a second service; and

preventing transmission of said data item.

18. A mobile communication device comprising:

a communication subsystem;

a processing device adapted to;

receive an instruction to transmit a data item;

determine that a first service has been selected for transmission of said data item using said communication subsystem;

determine that a portion of said data item is associated with a second service; and

prevent transmission of said data item.

19. A computer-readable medium containing computer-executable instructions that, when performed by a processor, cause said processor to:

receive an instruction to transmit a data item;

determine that a first service has been selected for transmission of said data item;

determine that a portion of said data item is associated with a second service; and

prevent transmission of said data item.

20. A method of facilitating data protection, said method comprising:

receiving an instruction to insert data into a data item;

determining that no service has been selected for transmission of said data item;

selecting a service;

allowing insertion of said data into said data item; and

transmitting said data item using said service.
