  • Computer-implemented PDF document management
    Patent number: 6895550
    Abstract: A PDF file is received from an external application and key information from the PDF file, concerning a PDF document contained in the PDF file, is extracted. The extracted key information is compared with analogous reference information stored for previously received PDF documents to determine a status for the received PDF document, which is provided to the external application from which the PDF file was received. The received PDF document is a duplicate if all the extracted key information matches analogous reference information, is an updated document if certain but not all the extracted key information matches analogous reference information, or is a new document if at least certain extracted key information does not match analogous reference information. If the PDF document is a duplicate document, processing of the PDF file is returned to the application without storing any extracted key information as reference information.
