摘要
Methods are provided for identifying and authenticating goods. A code or checksum based on information or an image relating to a good is derived and associated with a barcode to include on a label. The label is scanned by a recipient to authenticate the goods. Scanable code are provided based on an image by distilling an image into its hue components and using a grid to create a pattern. The pattern is readable by a scanner to obtain a code directly, or by consulting a look-up table. The code, barcode, digital barcode or scanable code can be included on a label or tag, such as an RFID tag.
