“GPO’s Authentication initiative focuses on the primary objective of assuring users that the information made available by GPO is official and authentic and that trust relationships exist between all participants in electronic transactions. In furthering GPO’s mission to provide permanent public access to authentic U.S. Government publications, GPO is working to afford users further assurance that files are unchanged since GPO authenticated them.
The Beta release of an Authenticated Congressional Bills application provides digitally signed and certified Adobe Portable Document Format (PDF) files for a sample set of Congressional Bills from the 110th Congress. GPO has signed and certified the House and Senate bills PDF files within this application as part of GPO’s initiative to reassure users that the online documents are official and authentic.
The documents in this database are available as ASCII text and digitally signed and certified Adobe Portable Document Format (PDF) files.”
