Abstract
Information decoded from a barcode or other machine-readable code within an image file is stored as character-based data in an auxiliary field, such as a comment field, of the image file. Subsequently, the information can be extracted from the auxiliary field so as to avoid the need to repeat the image analysis and decoding operation. In one aspect, the extracted data is validated to ensure that it is consistent with the machine-readable code.
