Abstract: A system and method for printing images for use in an authentication document from a plurality of different printers and/or capture devices. Each of the plurality of different printers and/or capture device having a unique ID. The images are printed on an authentication document with the unique ID. The system provides for verification that the presenter of an authentication document. The unique ID and/or other information may be provided in a form that is not visible under normal viewing conditions. By canning the image the unique ID may be obtained and used for authentication. The obtained ID may be compared with a known information stored at a database for confirming that the presenter of the authentication document is the individual to whom it was issued.

Abstract: A format for ultrasonic image data storage is described that utilizes a standard data formatting system to provide information specific to ultrasonic images and, in particular, sequences of ultrasonic images. The format utilizes a technique of tagged data records with a unique tag that extends the standardized to ultrasonic image specific tages. On tag denotes a particular image in a sequence of images which is marked as the image which is representative of the sequence. Specific areas of an ultrasonic image which contain distinct types of data are tagged to identify the type of data in the area. The distinct types of data can be arranged in unique ranges of data values so that a particular data value will inherently identify the type of data to which the value relates. Blocks of image data comprising monochrome or color data can be tagged as to the data type, enabling luminance data or red, green and blue data to be alternatively represented in the data values and automatically processed accordingly.
