Abstract

One embodiment provides a method, including: identifying, on an information handling device, a security level associated with an application window displayed on a display screen of the information handling device; capturing, using a sensor associated with the information handling device, an image of an area in front of the display screen; identifying, based upon analysis of the image, that an individual is present in the image; determining, using a processor, whether the individual is authorized to view the application window based upon the security level; and activating, responsive to determining that the individual is not authorized to view the application window, a privacy filter that obscures content in the application window from the individual. Other aspects are described and claimed.

First claim

What is claimed is:

1. A method, comprising:
identifying, on an information handling device, a security level associated with an application window displayed on a display screen of the information handling device;
capturing, using a sensor associated with the information handling device, an image of an area in front of the display screen, wherein the capturing is in response to a predetermined event;
identifying, based upon analysis of the image, that an individual is present in the image, wherein the identifying the individual comprises identifying at least two individuals in the image;
determining, using a processor, whether the individual is authorized to view the application window based upon the security level, wherein the security level adjusts based upon an additional application window, wherein the determining comprises determining that one of the at least two individuals is authorized to view the application window and another of the at least two individuals is not authorized to view the application window; and
activating, responsive to determining that the individual is not authorized to view the application window, a privacy filter that obscures content in the application window from the individual.

2. The method of claim 1 , wherein the capturing comprises continuously capturing the image while the application window is displayed on the display screen.

3. The method of claim 1 , wherein the identifying that the individual is present in the image comprises capturing facial characteristics associated with the individual.

4. The method of claim 3 , wherein the determining comprises:
comparing the facial characteristics to a database comprising facial biometric data for a plurality of authorized individuals having access to the application window at the security level; and
determining whether the facial characteristics share a predetermined level of similarity with the facial biometric data associated with one of the plurality of authorized individuals.

5. The method of claim 1 , wherein the activating comprises maintaining the privacy filter until the another of the at least two individuals is not detected in the area.

6. The method of claim 1 , further comprising receiving, from the one of the at least two individuals authorized to view the application window, an override command to deactivate the privacy filter.

7. The method of claim 1 , wherein the security level is based upon an internal designation or an external designation.

8. The method of claim 1 , wherein the activating the privacy filter comprises an obscuring action selected from the group consisting of: an obscuring of confidential information within the application window, an obscuring of the application window containing the confidential information, a moving of the application window off of the display screen, an iconizing of the application window, and an obscuring of the display screen.

9. The method of claim 1 , further comprising providing, concurrently with the activation of the privacy filter, a notification to an authorized user that an unauthorized user is detected in the area.

10. An information handling device, comprising:
a sensor;
a display screen;
a processor;
a memory device that stores instructions executable by the processor to:
identify a security level associated with an application window displayed on a display screen;
capture an image of an area in front of the display screen, wherein the capturing is in response to a predetermined event;
identify, based upon analysis of the image, that an individual is present in the image, wherein to identify the individual comprises identifying at least two individuals in the image;
determine whether the individual is authorized to view the application window based upon the security level, wherein the security level adjusts based upon an additional application window, wherein to determine comprises determining that one of the at least two individuals is authorized to view the application window and another of the at least two individuals is not authorized to view the application window; and
activate, responsive to determining that the individual is not authorized to view the application window, a privacy filter that obscures content in the application window from the individual.

11. The information handling device of claim 10 , wherein the instructions executable by the processor to capture comprise instructions executable by the processor to continuously capture the image while the application window is displayed on the display screen.

12. The information handling device of claim 10 , wherein the instructions executable by the processor to identify that the individual is present in the image comprise instructions executable by the processor to capture facial characteristics associated with the individual.

13. The information handling device of claim 12 , wherein the instructions executable by the processor to determine comprise instructions executable by the processor to:
compare the facial characteristics to a database comprising facial biometric data for a plurality of authorized individuals having access to the application window at the security level; and
determine whether the facial characteristics share a predetermined level of similarity with the facial biometric data associated with one of the plurality of authorized individuals.

14. The information handling device of claim 10 , wherein the activating comprises maintaining the privacy filter until the another of the at least two individuals is not detected in the area.

15. The information handling device of claim 10 , wherein the instructions are further executable by the processor to receive, from the one of the at least two individuals authorized to view the application window, an override command to deactivate the privacy filter.

16. The information handling device of claim 10 , wherein the security level is based upon at least one of: an intrinsic security measure and an extrinsic security measure.

17. The information handling device of claim 10 , wherein the instructions executable by the processor to activate the privacy filter comprise an obscuring action selected from the group consisting of: an obscuring of confidential information within the application window, an obscuring of the application window containing the confidential information, a moving of the application window off of the display screen, an iconizing of the application window, and an obscuring of the display screen.

18. A storage device that stores code, the code being executable by a processor and comprising:
code that captures an image associated with a user;
code that identifies a security level associated with an application window displayed on a display screen;
code that captures an image of an area in front of the display screen, wherein the capturing is in response to a predetermined event;
code that identifies, based upon analysis of the image, that an individual is present in the image, wherein to identify the individual comprises identifying at least two individuals in the image;
code that determines whether the individual is authorized to view the application window based upon the security level, wherein the security level adjusts based upon an additional application window, wherein to determine comprises determining that one of the at least two individuals is authorized to view the application window and another of the at least two individuals is not authorized to view the application window; and
code that activates, responsive to determining that the individual
