Abstract
The author employs fuzzy sets in a multilevel model for general-purpose database security. Sensitive information in database relations is meaningfully clouded by fuzzy sets. This is accomplished by broadening the possibility distributions constraining the values of sensitive attributes. The technique promotes the use of data and also maintains database security. Clouding with fuzzy sets is the middle ground between information release and information hiding/falsification. It nicely supplements the two security techniques and helps strike the right balance between user convenience and database security
