Abstract
Methods and apparatuses that synchronize a paper document to an associated digital document by establishing a mapping. An embedded interactive code (EIC) Document is created as a digital file that serves as an intermediate tier between the paper document and the digital document. Both the paper document and the EIC document are generated while printing the paper document. The EIC document records the corresponding EIC array allocations and a unique document identification number. An image capturing pen may generate a stroke on any page of paper document. With the EIC document, the methods and apparatuses inform an application the page and location on the page of the stroke.
