摘要： A method and system for thermal printing of secure documents. A contact thermal printing system includes: a) thermal print head having at least one heater element; and b) a thermal printer controller. The printer controller is programmed to: 1) move the print head in a predetermined pattern while the print head is in contact with a top coating of a thermal print medium; 2) overdrive the heater element during predetermined parts of the pattern to a temperature sufficient to soften or melt the top coating, thereby forming a pattern of striations in the top coating; and 3) control the heater element to print at least part of an image on the medium. The contact surface of the print head can have a specific pattern of features for forming the striations, whereby a pattern of striations formed can encode information both in the direction of the motion of the print head and transversely to the direction of motion. The pattern of striations can form a bar code. The image can be a postal indicium printed on a document which is a mail piece, or other documents having value, such as tax stamps and tickets, can be printed.

摘要： A method for detecting a copy of a composite image that includes a first image and a second image that has information embedded in the second image that will change in appearance when the first and second images are scanned or photocopied. The foregoing is accomplished by scanning the first and second images, and detecting a change in appearance of the second image that indicates the first and second images were scanned or photocopied.

摘要： A printed barcode including first basic barcode information stored in a first basic mode of printed data storage, and second additional enhanced barcode information stored in a second enhanced mode of printed data storage. The second information is printed, at least partially, as a component of the first information. The first information is adapted to be read by a basic barcode reader. The second information is adapted to be read by an enhanced barcode reader and cannot be read by the basic barcode reader.

摘要： The present invention includes apparatus and methods for printing and verifying postage stamps on demand via a personal postage stamp printer. The indicia by which the stamp is printed includes a color bar sequence and a data field including data that corresponds to the color bar sequence. To authenticate the stamp, the data field is read and the color bar sequence data included in the data field is compared with the data generated by detecting the color bar sequence itself.
