Abstract

In one implementation, a physical version of a document is converted to a digital representation of the physical version and a new certificate is computed for the digital representation of the physical version. The new certificate is computed based on the digital representation of the physical version, at least one processing step performed on the digital representation, and a prior certificate computed for a prior digital representation indicative of the physical version. In another implementation, a document is validated.
