Providing a locking technique for electronic displays

摘要

In one embodiment, the present invention includes a method for receiving in a persistent electronic display an authentication code from an end user, determining whether the received authentication code corresponds to a stored authentication code, and displaying a selected image on the persistent electronic display if the received authentication code corresponds to the stored authentication code, and otherwise displaying an obscured image on the persistent electronic display. This obscured image may be in an unreadable format in which information of the selected image is unreadable but a type of document represented by the selected image is determinable. Other embodiments are described and claimed.

主权项

1. An apparatus comprising:
a display to display an image persistently in absence of power delivery to the display; an authentication logic to determine whether an authentication code received from an end user corresponds to an authentication code associated with the image; a render logic to render the image for display on the display; and a display logic to enable display of the image in a readable format when the authentication code corresponds to the associated authentication code, and to otherwise display the image in an unreadable format in which information of the image is unreadable but a type of document represented by the image is determinable.
