Discouraging screen capture
View Patent ↗Screen capture mitigation is disclosed. A first finger of a user is detected in a first designated region of a display. Content is displayed when the first finger is detected in the first designated region of the display. Periodically, a determination is made whether the first finger is detected in the first designated region of the display. The content is ceased to be displayed in response to a determination that the first finger is outside the first designated region of the display.
1. A system for discouraging screen capture, the system comprising:
a processor configured to:
provide a first designated region of a display to a user to allow the user to view a first file;
detect a first location of a first finger of the user in the first designated region of the display;
display the first file when the first finger is held at the first location in the first designated region of the display;
detect a second location of the first finger;
determine whether the second location is located within the first designated region of the display by determining whether a distance between the first location and the second location is greater than a predetermined threshold;
indicate an attempted screen capture by the user when the distance is greater than the predetermined threshold; and
cease displaying the first file in response to the indication of the attempted screen capture by the user and a determination that the second location is outside the first designated region of the display; and
a memory coupled to the processor and configured to provide the processor with instructions.
2. The system of claim 1 , wherein the first location and the second location are represented via Cartesian coordinates.
3. The system of claim 1 , wherein the distance is adjustable.
4. The system of claim 1 wherein the presence of multiple fingers is detected.
5. The system of claim 1 wherein the processor is further configured to detect a third location of a second finger in a second designated region of the display.
6. The system of claim 5 , wherein the processor is further configured to:
detect a fourth location of the second finger;
determine whether the fourth location is within the second designated region of the display; and
cease displaying the first file in response to a determination that the fourth location is outside the second designated region of the display.
7. The system of claim 1 wherein the first communication has an expiration time.
8. The system of claim 7 wherein the processor is further configured to enforce the expiration time.
9. A method of discouraging screen capture, the method comprising:
providing a first designated region of a display to a user to allow the user to view a first file;
detecting a first location of a first finger of the user in the first designated region of the display;
displaying the first file when the first finger is held at the first location in the first designated region of the display;
detecting a second location of the first finger;
determining whether the second location is located within the first designated region of the display by determining whether a distance between the first location and the second location is greater than a predetermined threshold;
indicating an attempted screen capture by the user when the determined distance is greater than the predetermined threshold; and
ceasing display of the first file in response to the indication of the attempted screen capture by the user and a determination that the second location is outside the first designated region of the display.
10. The method of claim 9 , further comprising:
detecting a third location of a second finger in a second designated region of the display.
11. The method of claim 10 , further comprising:
detecting a fourth location of the second finger;
determining whether the fourth location is within the second designated region of the display; and
ceasing display of the first file in response to a determination that the fourth location is outside the second designated region of the display.
12. The method of claim 9 , further comprising:
enforcing an expiration time associated with the first file.
13. A computer program product embodied in a non-transitory tangible computer readable storage medium and comprising computer instructions for:
providing a first designated region of a display to a user to allow the user to view a first file;
detecting a first location of a first finger of the user in the first designated region of the display;
displaying the first file when the first finger is held at the first location in the first designated region of the display;
detecting a second location of the first finger;
determining whether the second location is located within the first designated region of the display by determining whether a distance between the first location and the second location is greater than a predetermined threshold;
indicating an attempted screen capture by the user when the determined distance is greater than the predetermined threshold; and
ceasing display of the first file in response to the indication of the attempted screen capture by the user and a determination that the second location is outside the first designated region of the display.
14. The computer program product of claim 13 , further comprising instructions to detect a third location of a second finger in a second designated region of the display.
15. The computer program product of claim 14 , further comprising instructions to:
detect a fourth location of the second finger;
determine whether the fourth location is within the second designated region of the display; and
cease displaying the first file in response to a determination that the fourth location is outside the second designated region of the display.
16. The computer program product of claim 13 , further comprising instructions to enforce an expiration time associated with the first file.
