Context-aware obfuscation and unobfuscation of sensitive content
Techniques are disclosed for context-aware obfuscation and unobfuscation of sensitive content in the display of the sensitive content. An example methodology implementing the techniques includes receiving content for display, the content including metadata indicative of a location of at least one item of sensitive content within the received content, and determining at least one contextual factor. The method also includes, responsive to a determination to obfuscate the item of sensitive content based on the at least one contextual factor, displaying the item of sensitive content in obfuscated form. The method may also include, responsive to a determination to not obfuscate the item of sensitive content based on at least one contextual factor, displaying a non-obfuscated version of the item of sensitive content.
1. A method comprising:
receiving, by a computing device, content for display, the content including at least one identified item of sensitive content within the content;
receiving, by the computing device, metadata associated with the content, the metadata is indicative of coordinates of a position of the at least one identified item of sensitive content within the received content and at which to obfuscate display of the at least one identified item of sensitive content;
determining, by the computing device, at least one contextual factor; and
responsive to a determination to obfuscate the at least one identified item of sensitive content based on the at least one contextual factor, causing, by the computing device, displaying of the at least one identified item of sensitive content in obfuscated form based on the coordinates.
2. The method of claim 1 , wherein displaying the at least one identified item of sensitive content in obfuscated form includes applying an overlay with distortion effects, applying a transformation, adding an artifact, or redacting the at least one identified item of sensitive content.
3. The method of claim 1 , wherein determining the at least one contextual factor includes detecting another user being physically proximate to the computing device based on a security zone associated with the computing device.
4. The method of claim 3 , wherein detecting the presence of another user in physical proximity to the computing device includes detecting presence within the security zone.
5. The method of claim 1 , further comprising, responsive to a determination to not obfuscate the at least one identified item of sensitive content based on at least one contextual factor, displaying a non-obfuscated version of the at least one identified item of sensitive content.
6. The method of claim 1 , further comprising displaying, via the computing device, a non-obfuscated version of the at least one identified item of sensitive content within an application window, and wherein determining the at least one contextual factor includes detecting a timeout of an inactivity timer associated with the application window.
7. The method of claim 1 , wherein the at least one identified item of sensitive content is displayed in obfuscated form and the method further comprises:
responsive to a request to unobfuscate the at least one identified item of sensitive content being displayed in obfuscated form,
authenticating the request to unobfuscate the at least one identified item of sensitive content; and
displaying of the at least one identified item of sensitive content to be readable.
8. A non-transitory machine-readable medium encoding instructions that when executed by one or more processors cause a process to be carried out, the process comprising:
receiving content for display, the content including at least one identified item of sensitive content within the content;
receiving metadata associated with the content, the metadata is indicative of coordinates of a position of the at least one identified item of sensitive content within the received content and at which to obfuscate display of the at least one identified item of sensitive content;
determining at least one contextual factor; and
responsive to a determination to obfuscate the at least one identified item of sensitive content based on the at least one contextual factor, causing, by one of the one or more processors, displaying of the at least one identified item of sensitive content in obfuscated form based on the coordinates.
9. The non-transitory machine-readable medium of claim 8 , wherein displaying the at least one identified item of sensitive content in obfuscated form includes applying an overlay with distortion effects to the at least one identified item of sensitive content.
10. The non-transitory machine-readable medium of claim 8 , wherein displaying the at least one identified item of sensitive content in obfuscated form includes applying a transformation to the at least one identified item of sensitive content.
11. The non-transitory machine-readable medium of claim 8 , wherein displaying the at least one identified item of sensitive content in obfuscated form includes redacting the at least one identified item of sensitive content.
12. The non-transitory machine-readable medium of claim 8 , wherein determining the at least one contextual factor includes detecting another user being physically proximate to a computing device being used to display the item of sensitive content based on a security zone associated with the computing device.
13. The non-transitory machine-readable medium of claim 12 , wherein detecting the presence of another user in physical proximity to the computing device includes detecting presence within the security zone.
14. The non-transitory machine-readable medium of claim 8 , the process further comprising, responsive to a determination to not obfuscate the at least one identified item of sensitive content based on at least one contextual factor, displaying a non-obfuscated version of the at least one identified item of sensitive content.
15. The non-transitory machine-readable medium of claim 8 , the process further comprising displaying of the at least one identified item of sensitive content to be readable within an application window, and wherein determining the at least one contextual factor includes detecting a timeout of an inactivity timer associated with the application window.
16. The non-transitory machine-readable medium of claim 8 , wherein the at least one identified item of sensitive content is displayed in obfuscated form, the process further comprising:
responsive to a request to unobfuscate the at least one identified item of sensitive content displayed in obfuscated form,
authenticating the request to unobfuscate the at least one identified item of sensitive content; and
displaying a non-obfuscated version of the at least one identified item of sensitive content.
17. A system comprising:
a memory; and
one or more processors in communication with the memory and configured to:
receive content for display, the content including at least one identified item of sensitive content within the content;
receive metadata associated with the content, the metadata is indicative of coordinates of a position of the at least one identified item of sensitive content within the received content and at which to obfuscate display of the at least one identified item of sensitive content;
determine at least one contextual factor; and
responsive to a determination to obfuscate the at least one identified item of sensitive content based on the at least one contextual factor, cause one of the one or more processors to display the at least one identified item of sensitive content in obfuscated form based on the coordinates.
18. The system of claim 17 , wherein to determine the at least one contextual factor includes to detect another user being physically proximate to a computing device being used to display the at least one identified item of sensitive content.
19. The system of claim 17 , wherein the one or more processors in communication with the memory is further configured to, responsive to a determination to not obfuscate the at least one identified item of sensitive content based on at least one contextual factor, cause a non-obfuscated version of the at least one identified item of sensitive content to be displayed.
20. The system of claim 17 , wherein the at least one identified item of sensitive content is displayed in obfuscated form, the one or more processors in communication with the memory further configured to:
responsive to a request to unobfuscate the at least one identified item of sensitive content being displayed in obfuscated form,
authenticate the request to unobfuscate the at least one identified item of sensitive content; and
cause a non-obfuscated version of the at least one identified item of sensitive content to be displayed.
