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.
