A system and method for sending a packet with a position address and line scan data from a first device over a 1394 interface to a second device. The present invention loads a camera, an illuminator, and a microprocessor with set-up instructions and a start pulse. The camera captures a line-by-line image of an object placed on the surface of a sliding prism. Position data, corresponding to the captured line-by-line image, is logged as the position address. The position address is combined with the line-by-line image to form a packet. The packet is sent to the second device for processing and viewing the image.

What is claimed is: 1. A method for communicating image data from a fingerprint scanning device having a camera and a sliding prism to a computer over a 1394 interface, comprising the steps of: (a) receiving set-up instructions for the camera and calibration instructions for the fingerprint scanning device from the computer over the 1394 interface; (b) loading the camera with the received set-up instructions; (c) capturing line-by-line image data associated with an object placed on the sliding prism; (d) generating absolute position data corresponding to the line-by-line image data, wherein the absolute position data is referred to as the position address data; (e) generating a packet including the line-by-line image data and the corresponding position address data; and (f) sending the packet to the computer over the 1394 interface. 2. The method of claim 1, further comprising the steps of: (g) decoding the packet at the computer to recover the line-by-line image data and the position address data; and (h) forming an image of the object using the line-by-line image data and the position address data. 3. The method of claim 2, further comprising the step of displaying the image on the computer. 4. The method of claim 1, wherein step (e) further comprises the step of encoding the packet for 1394 data transmission. 5. The method of claim 1, wherein step (d) further comprises the step of converting raw position data into the absolute position data. 6. The method of claim 1, wherein step (c) further comprises the step of sending a start of line signal followed by the line-by-line image data. 7. The method of claim 1, wherein step (c) comprises the step of capturing a line-by-line fingerprint image of a finger or fingers placed on the sliding prism. 8. The method of claim 1, wherein step (f) comprises the step of sending the packet to a personal computer (PC). 9. The method of claim 8, further comprising the step of displaying the image on a monitor attached to the computer. 10. The method of claim 1, wherein step (b) further comprises initializing an illuminator and a microprocessor based on the received set-up and calibration instructions. 11. A system for communicating image data from a fingerprint scanning device having a camera and a sliding prism over a 1394 interface to a computer, comprising: (a) means for receiving set-up instructions for the camera and calibration instructions for the fingerprint scanning device from the computer over the 1394 interface; (b) means for loading the camera with the received set-up instructions; (c) means for capturing line-by-line image data associated with an object placed on the sliding prism; (d) means for generating absolute position data corresponding to the line-by-line image data, wherein the absolute position data is referred to as the position address data; (e) means for generating a packet including the line-by-line image data and the corresponding position address data; and (f) means for sending the packet to the computer over the 1394 interface. 12. The system of claim 11, further comprising: (g) means for decoding the packet at the computer to recover the line-by-line image data and the position address data; and (h) means for forming an image of the object using the line-by-line image data and the position address data. 13. The system of claim 12, further comprising means for displaying the image on the computer. 14. The system of claim 12, further comprising means for displaying the image on a monitor attached to the computer. 15. The system of claim 11, wherein said means for generating a packet further comprises means for encoding the packet for 1394 data transmission. 16. The system of claim 11, wherein said means for generating position data further comprises means for converting raw position data into absolute position data. 17. The system of claim 11, wherein said means for capturing further comprises means for sending a start of line signal followed by the line-by-line image data. 18. The system of claim 11, wherein said means for capturing comprises means for capturing line-by-line image data of at least one finger placed on the sliding prism. 19.
