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 party having a particular access privilege or authorization to make modifications to various restricted portions including an authentication region and a protected region. One possible aspect includes performing a verification analysis of data indicia in a restricted portion of the e-paper media. Additional possible system and process components may determine an authenticity status of the data indicia, and provide an output result.
