Abstract
Techniques for protecting imaging access of electronic paper are described herein. For example, an electronic paper device with protected imaging access includes a substrate, an e-paper surface disposed on the substrate, a removable cover to prevent alteration of the e-paper surface when the cover is disposed over the e-paper surface, and a reversible locking mechanism engaging with the cover to secure the cover in place over the e-paper surface. A method for secure writing to e-paper is also provided.
