User accessibility to electronic paper

摘要

A system and method helps to control “read” and/or “write” access to electronic paper (e-paper). Informational data may be on a restricted portion of e-paper material that is protected by a security methodology accessible to authorized entities. Some embodiments maintain a record of access activity regarding the restricted portion, and a record of access activity regarding use of an item or product or service related to the e-paper informational data. Some implementations include an authorization listing of a person or entity having a particular access privilege or a supervisory privilege to make authorization and data changes. Authorization records may involve an access privilege to receive a status output regarding prior access activity and/or current status.
