Filed:

Jan 13, 1999

Appl. No.:

9/229694

Inventors:

Andrew P. Ho - Beverly Hills CA

International Classification:

G06F 1300

US Classification:

709225

Abstract:

A system for managing sensitive data is described. The system prevents a system administrator from accessing sensitive data by storing data and identifier information on different computer systems. Each query is encrypted using two codes, the first code readable only by an identifier database and a second code readable only by a data access database. By routing the data path from a source terminal to the identifier database which substitutes an internal ID, then to the data access database and back to the source terminal, data security is significantly improved.
