Abstract

Privacy protection of data content is provided by identifying one or more applications running on a suitably configured device, and marking each of the applications to indicate that a respective one of the applications is permitted or not permitted to issue messages in an all share public mode. The data content of such messages is hidden from public view in response to the application not having the requisite permission to issue messages in the all share public mode. A computer program and mobile terminal device for providing privacy protection of data content are also presented.

Claims

1. Method, comprising:

running one or more application programs on a presentation device configured to run said application programs and configured to show data content of said one or more application programs on a display screen of said presentation device and on an external viewing device in communication connectivity with the presentation device when the presentation device is in an all share public mode operative state, at least one of said one or more application programs comprising a presentation application program and at least one of said one or more application programs comprising a notification application program;

identifying each of said one or more notification application programs;

marking each of said identified one or more notification application programs with an issue notification all share public mode permission status to indicate that a respective one of said one or more notification application programs is permitted or not permitted to issue messages when said presentation device is in an all share public mode operative state;

including an inquiry sequence in the notification application program to determine when the presentation device is in an all share public mode operative state;

determining if the notification application program is permitted to issue messages in response to the presentation device being in an all share public mode operative state, and

displaying the message data content on the display screen of the presentation device and on the external viewing device in communication connectivity with the presentation device in response to determining the notification application program is permitted to issue messages.

2. The method as defined in claim 1 further comprising:

creating a first listing of said one or more identified notification application programs marked with permission to issue messages when the presentation device is in an all share public mode operative state;

creating a second listing of said one or more notification application programs marked as not having permission to issue messages when the device is in an all share public mode operative state;

operating the presentation device in an all share public mode;

detecting that the all share mode in the presentation device is activated;

comparing the identified notification application program wishing to display data content with the first listing and with the second listing of said one or more identified notification application programs;

showing the data content of the identified notification application program in response to determining that the identified notification application program is listed in said first listing of notification application programs marked with permission to issue messages, and

not showing the data content of the identified notification application programs in response to determining that the identified notification application program is listed in said second listing of notification application programs not having permission to issue messages.

3. The method as defined in claim 2 further comprising:

determining prior to interrupting to display a message whether the notification application program is permitted or not permitted to show the message;

hiding the message in response to determining the notification application program is not permitted to show the message.

4. The method as defined in claim 3 further comprising displaying the message on the display screen of the presentation device only.

5. The method as defined in claim 1 wherein the message further comprises displaying an icon.

6. The method as defined in claim 1 wherein the message further comprises displaying a text message.

7. The method as defined in claim 1 wherein the message further includes providing an audible message.

8. The method as defined in claim 1 further comprising removing personal information from said messages prior to issuing the message.

9. The method as defined in claim 1 wherein said notification application program is an instant messaging application program.

10. The method of providing privacy protection as defined in claim 1 wherein said notification application program is an alarm alert application program.

11. The method as defined in claim 1 wherein said notification application program is a calendar application program.

14. The method as defined in claim 1 further comprising issuing the message and hiding the information data content of the message.

15. The method as defined in claim 1 further comprising issuing the message and showing the information data content of the message on the display screen of the presentation device and not showing the information data content of the message on the external viewing device.

16. The method as defined in claim 1 further comprising issuing the message and showing the information data content of the message on the display screen of the presentation device and on the external viewing device.

17. The method as defined in claim 1 wherein the external viewing device further comprises a projection device.

12. A computer program product carried on a storage medium and executable by a processor in a presentation device comprising:

program code for running one or more application programs on a presentation device configured to run said application programs and configured to show data content of said one or more application programs on a display screen of said presentation device and on an external viewing device in communication connectivity with the presentation device when the presentation device is in an all share public mode operative state, at least one of said one or more application programs comprising a presentation application program and at least one of said one or more application programs comprising a notification application program;

program code for identifying each of said one or more notification application programs running on the presentation device;

program code for suitably marking each of the identified one or more notification application programs with an issue notification all share public mode permission status to indicate that a respective one of said one or more notification application programs is permitted or not permitted to issue messages when the presentation device is in an all share public mode operative state;
