CM/ECF uses two programs to verify the integrity of PDF documents -
PDF check and ChkDocs. ChkDocs is run nightly on the CM/ECF live database and checks for documents that have "signatures" that have been altered. It then writes to a log file on the inside server and sends an e- mail to the designated administrator. PDF check automatically analyzes the structure of each PDF document that is uploaded into CM/ECF to ensure that it does not contain any action, such as viruses, within it that could be dangerous to the host machine or any PC accessing the document. It also collects information as whether the document is, in fact, a pdf document, if it is encrypted, and the number of pages. The Utility menu on the CM/ECF application contains a menu option to "Verify a Document" should a user wish to run the PDF
CHECK program. (Effective: February 2002)
