METHOD FOR ADDING PROVENANCE METADATA TO FILES DOWNLOADED FROM A WEB-BASED SOURCE

摘要

A method provides additional information about a file being downloaded from a web-based source. The downloaded file is modified by adding provenance metadata to the downloaded file, the provenance metadata identifying the web-based source of the downloaded file. Upon adding the provenance metadata, the modified downloaded file is stored. The provenance metadata can be read or displayed at a later time to identify the web-based source of the downloaded file.
