ABSTRACT:
A system and method for increasing the reliability of data matches between data stored in a database and newly provided data. The system relies on the prescreening of newly provided data patterns to insure that any newly provided data pattern is not ambiguous with existing data patterns. A threshold level is calculated for each newly provided data pattern and the invention determines which stored data pattern is closest to, or most likely to be confused with, the newly provided data pattern. The invention temporarily prohibits the new data pattern from being added to the database if it is likely to be confused with a stored data pattern. A user can then choose either to change the new data pattern to a different pattern or to allow the potentially confusing new data pattern to be added to the database. The calculated threshold levels can be set for both individual users and groups of users. The data patterns can consist of speech, images, graphs or other data.
