Abstract
Disclosed are systems and methods that provide authentication for printed and/or electronic versions of a document through the use of a document authentication device in the form of a computational tag configured for short-range wireless communication only. This document authentication device receives authentication information for a document from a computerized device over a wireless communication link and uses this authentication information to generate encoded data to be embedded in the document in order to establish the authenticity of the document by functioning as an imprimatur. Specifically, when embedded in the document, this encoded data can add a visible feature or non-visible feature that, upon inspection, establishes the authenticity of an electronic version of the document and/or can add a printable feature, which will be readable off a surface of a printed version of the document to establish the authenticity of that printed version.
