1. A system comprising:
- circuitry configured for detecting at least one instance of unauthorized alteration of at least one of a coupling link of at least one electronic paper material with at least one item or data indicia associated with at least one portion of the at least one electronic paper material; and
circuitry configured for outputting at least one visual alert on one or more portions of the at least one electronic paper material at least partly in response to detection of the at least one instance of unauthorized alteration of at least one of the coupling link of the at least one electronic paper material with the at least one item or the data indicia associated with the at least one portion of the electronic paper material.

Abstract
A system and method to control the writing on electronic paper (e-paper). An e-paper device may incorporate authentication indicia as part of informational data written on e-paper material. The informational data is protected by a security methodology that is accessible to authorized entities. A reader device may be used to help make a verification determination of whether encrypted or encoded data has been altered. In some instances an output alert operably coupled to the reader device serves as a verification status indicator.

25. A method comprising:
-
detecting, using one or more computer processors, at least one instance of unauthorized alteration of at least one of a coupling link of at least one electronic paper material with at least one item or data indicia associated with at least one portion of the at least one electronic paper material; and outputting at least one visual alert on the at least one portion of the at least one electronic paper material at least partly in response to detection of the at least one instance of unauthorized alteration of the at least one of a coupling link of the at least one electronic paper material with the at least one item or data indicia associated with the at least one portion of the electronic paper material.
