Systems and methods consistent with embodiments of the present invention provide for a method for preserving and maintaining document integrity. In some methods for preserving and maintaining document integrity, the contents of a document, or contents of a document layer may be encoded into a machine-readable form. In some embodiments, the encoded information may be represented using a 2-dimensional bar code. In some methods for preserving and maintaining document integrity, the machine-readable code is printed along with contents of the document based on space available in the document. In some embodiments, a printed document containing the machine-readable code may be scanned and digitized, and content extracted from the scanned data. In some embodiments, the machine-readable code printed on the document is used to recreate layer data from the printed document.
A method of retrieving content and meta-data associated with the content from at least one page of a printed document containing document content data and a first machine-readable encoding on one face of the at least one page, the method comprising:
A computer-readable medium containing instructions for controlling a computer system to perform steps in a method for retrieving the content of document sections and meta-data associated with document sections, from a printed document containing a first machine-readable encoding, the steps comprising:
