Abstract
A system, method, and computer program for monitoring and corrupting a data stream, includes a data stream transmitting device having a barcode scanner that transmits a stream of data corresponding to a scanned barcode; a data stream receiver device having a barcode processing system that receives the stream; and a monitoring and corrupting device coupled therebetween having a database storing rules for detecting and corrupting patterns of data in the stream, and which monitors the stream, and based on the rules determines if the stream is unwanted, and if so corrupts the stream and transmits the corrupted stream to the barcode processing system so that the barcode data stream cannot be correctly received by the data stream receiver device. Otherwise, if the stream of data is wanted, the stream of data is allowed to be correctly received by the data stream receiver device.
