Method and system for corrupting unwanted data in a communications stream

An electronic method for monitoring and corrupting a data stream, the method comprising:

• transmitting with a data stream transmitting device, including a barcode scanner a stream of data corresponding to a scanned barcode;
• receiving with a data stream receiver device, including a barcode processing system the stream of data corresponding to the scanned barcode;
• coupling a monitoring and corrupting device between the data stream transmitting device and the data stream receiver device, and including in the monitoring and corrupting device a database, and storing with the database rules for detecting patterns of data in the stream of data corresponding to the scanned barcode, and rules for corrupting the detected patterns of data;
• monitoring with the monitoring and corrupting device the stream of data corresponding to the scanned barcode, and based on the detecting and corrupting rules determining if the stream of data corresponds to the scanned barcode is unwanted, and if so corrupting the stream of data corresponding to the scanned barcode and transmitting the corrupted data stream to the data stream receiver device so that the barcode data stream cannot be correctly received by the data stream receiver device;
• and
• monitoring with the monitoring and corrupting device the stream of data corresponding to the scanned barcode, and based on the detecting and corrupting rules determining if the stream of data corresponds to the scanned barcode is wanted, and if so allowing the stream of data corresponding to the scanned barcode to be correctly received by the data stream receiver device.

A computer program product for an electronic method for monitoring and corrupting a data stream including one or more computer readable instructions embedded on tangible, non-transitory computer readable medium and configured to cause one or more computer processors to perform the steps of:

• transmitting with a data stream transmitting device, including a barcode scanner a stream of data corresponding to a scanned barcode;
• receiving with a data stream receiver device, including a barcode processing system the stream of data corresponding to the scanned barcode;
• coupling a monitoring and corrupting device between the data stream transmitting device and the data stream receiver device, and including in the monitoring and corrupting device a database, and storing with the database rules for detecting patterns of data in the stream of data corresponding to the scanned barcode, and rules for corrupting the detected patterns of data;
