Obfuscating the display of information and removing the obfuscation using a filter

摘要

This is directed to obfuscating a display to secure the display of information provided to a user. An electronic device can modulate the display of information using different approaches, including for example by adding artifacts or changing the color, frequency or polarity of displayed information, thus obfuscating the display. To view the displayed information, a user can place a filter between the user and the display (e.g., as part of glasses) such that the filter can remove or undo the obfuscation. In some embodiments, the device can display different confidential information for several users simultaneously, where different obfuscation approaches are used for each user. This can allow several users to interact with the device simultaneously while ensuring that each user's information remains confidential.

主权项

1. A method for securing the display of information provided by an electronic device, comprising:
identifying private information to display, wherein identifying private information to display comprises receiving, from a user, a selection of a region of a display device that includes the identified private information; retrieving an obfuscation process associated with the identified private information, wherein the effect of the obfuscation process can be removed by a filter associated with the private information; with image processing circuitry in the electronic device, applying the obfuscation process to the region that includes the identified private information to generate an obfuscated display, wherein the private information is not discernable in the obfuscated display; with the display device in the electronic device, displaying the obfuscated display, wherein applying the obfuscation further comprises at least one of:
rotating the identified private information about at least one point;spatially distorting the identified private information;scaling the identified private information;reflecting the identified private information; andshearing the identified private information; and with non-transitory storage in the electronic device, storing the identified private information in its obfuscated form.
