Abstract

An apparatus and method of displaying a message on a display of a computing device. The message comprises at least a first attachment. At least a portion of the message is displayed to a user. The displayed portion comprises an identifier for the first attachment. In one embodiment, a security encoding indicator is associated with the identifier for the first attachment and displayed to the user. If a security encoding has been applied to the first attachment, the security encoding indicator indicates the security encoding applied to the first attachment.

Claims

1. A method of displaying a message on a computing device, wherein the message comprises at least a first attachment, the method comprising:

displaying at least a portion of the message, wherein the displayed portion comprises an identifier for the first attachment; and

displaying at least one security encoding indicator, the at least one security encoding indicator being associated with the identifier for the first attachment;

wherein if at least one security encoding has been applied to the first attachment, the at least one security encoding indicator indicates the at least one security encoding applied to the first attachment.

2. The method of claim 1, wherein the computing device is a mobile device.

3. The method of claim 1, wherein the at least one security encoding indicator indicates that one of the conditions selected from the following group applies to the first attachment:

the first attachment is both signed and encrypted;

the first attachment is signed but not encrypted;

the first attachment is encrypted but not signed; and

the first attachment is neither signed nor encrypted.

4. The method of claim 1, wherein the at least one security encoding indicator indicates whether the first attachment is signed.

5. The method of claim 4, wherein the at least one security encoding indicator comprises an icon that indicates that the first attachment is signed.

6. The method of claim 4, wherein the at least one security encoding indicator further identifies a key holder of a key used to sign the first attachment.

7. The method of claim 4, further comprising providing a menu option such that when the menu option is selected, data from a certificate, with which a key used to sign the first attachment is associated, is displayed.

8. The method of claim 4, wherein the at least one security encoding indicator further indicates whether a key used to sign the first attachment is associated with a trusted certificate.

9. The method of claim 4, wherein the at least one security encoding indicator comprises an icon that indicates that a digital signature associated with the first attachment failed to verify successfully.

10. The method of claim 1, wherein the at least one security encoding indicator indicates that the first attachment is encrypted.

11. The method of claim 10, wherein the at least one security encoding indicator further identifies a key holder of a key used to encrypt the first attachment.

12. The method of claim 10, wherein the at least one security encoding indicator comprises an icon that indicates that the first attachment is encrypted.

13. The method of claim 1, wherein the at least one security encoding indicator comprises a bar associated with the first attachment that indicates whether the first attachment is at least one of encrypted or signed.

14. The method of claim 1, wherein the at least one security encoding indicator comprises a border associated with the first attachment that indicates whether the first attachment is at least one of encrypted or signed.

15. The method of claim 1, wherein the at least one security encoding indicator comprises at least one of a plurality of colors applied to the identifier for the first attachment that indicates whether the first attachment is at least one of encrypted or signed.

16. The method of claim 1, wherein the at least one security encoding indicator comprises at least one of a plurality of font sizes applied to the identifier for the first attachment that indicates whether the first attachment is at least one of encrypted or signed.

17. The method of claim 1, wherein the at least one security encoding indicator comprises at least one of a plurality of font styles applied to the identifier for the first attachment that indicates whether the first attachment is at least one of encrypted or signed.

18. The method of claim 1, wherein the message comprises a plurality of attachments.

19. The method of claim 18, wherein the act of displaying at least a portion of the message comprises displaying an identifier for each of the plurality of attachments, and wherein the act of displaying at least one security encoding indicator comprises displaying at least one security encoding indicator for each of the plurality of attachments, the respective at least one security encoding indicator being associated with the identifier for the corresponding attachment;

and wherein for each of the plurality of attachments, if at least one security encoding has been applied thereto, the respective at least one security encoding indicator indicates the at least one security encoding applied to the corresponding attachment.

20. The method of claim 1, wherein the message comprises an e-mail message.

21. A computer-readable medium upon which a plurality of instructions is stored, the instructions for performing the acts of the method as claimed in claim 1.

22. A mobile device comprising:

a processor;

a memory; and

a display;

wherein in operation, an application programmed to perform the acts of the method as claimed in claim 2 executes on the mobile device such that a security encoding indicator is generated for display on a display of the mobile device.
