The underlying techniques to protect the content include digital signatures , watermarking , encryption , scrambling , and key generation and management . The serious juggler must see beyond throws and catches to the underlying technique and subtleties . Google is generally thought of as an AJAX pioneer , with applications such as Google Suggest , GMail , and Google Maps all making extensive use of the underlying techniques . Independent of complexity theory , the underlying techniques reveal another interesting connection between analytic number theory and polynomial systems . We will transfer the software as well as the underlying techniques to industry ( via collaboration with vendor research labs ) , to MITRE direct-funded projects ( via proposals for improved Web service security architectures ) , and to the Air Force ( via the resulting software and the vision it embodies ) . Injury to the TM occurs 1.9 % of the time and can be repaired by the underlay technique . Network stream secrecy can be pretty much guaranteed with appropriate cryptography , even though technical issues such as key distribution infrastructures and political ones such as exportability and key escrow always seem to overshadow the underlying techniques .
