AbstractA data processing security device, attached to computing equipment, inserts labels into a data stream that indicate security controls for the data. The security device may also be configured to detect security labels within a data stream and inhibit the flow of data. It also may replace data within a data stream if it detects labeled fields which indicate that privacy should be imposed.
