Spring 1992: US Intelligence Official Mentions Connection between PROMIS and Main Core Database to Businessman

An unnamed US intelligence official tells businessman William Hamilton that there is a connection between the PROMIS database and search program and the Main Core database. Hamilton is a former NSA official who helped developed PROMIS, but is now involved in a series of disputes with the government over money he says it owes his company, Inslaw. Main Core is a database that is said to collect sensitive information, including about US persons. The specific type of connection is not certain. This is one of three times officials will tell Hamilton about the link (see 1995 and July 2001). [Salon, 7/23/2008]
