''Because of problems getting some government agencies to participate in the project, the wide area distribution of information isn’t done over a private network. Instead, communication takes place over the Internet. Data is first formatted as needed and then encrypted using secure socket layer technology, the same approach used by banks and financial institutions. After transmission, the information is again processed by systems internal to a jurisdiction, and then delivered as needed.

In addition to infosharing, there are also data analysis capabilities in RISA. The former was handled by products from Crossflo Systems Inc. of San Diego, Calif. and the latter was provided by Memex Inc. of Vienna, Va. That allows investigators to find nuggets of information by running repeated queries aimed at data gathered from disparate sources. ''
