Many documents such as Microsoft WORD, EXCEL and digital pictures contain internal information not viewable by the user or creator of the document.  Universal Data Forensics has the capability to extract this information and use it as evidence if needed.
In one criminal case a defendant was offered a very good plea deal due to UDF's findings that law enforcement took digital pictures of evidence inside a home which was hours before the search warrant was granted and executed.

In civil cases this information has been invaluable in proving or disproving how such files were handled.
