[0001] This application claims the benefit under 35 U.S.C. .sctn. 119(e) of U.S. Provisional Application No. 60/147,498, filed Aug. 9, 1999, which is incorporated by reference herein in its entirety. CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This patent application is potentially related to the following co-pending U.S. utility patent applications: [0003] 1. "Calibration and Correction in a Fingerprint Scanner," Ser. No. (to be assigned), Attorney Docket No. 1823.0140000, by Irving et al., filed concurrently herewith and incorporated in its entirety herein by reference; [0004] 2.

"Method, System, and Computer Program Product for Control of Platen Movement during a Live Scan," Ser. No. (to be assigned), Attorney Docket No. 1823.0220000, by G. Barton et al., filed concurrently herewith and incorporated in its entirety herein by reference. BACKGROUND OF THE INVENTION [0007] 1. Field of the Invention [0008] The present invention is generally directed to fingerprint imaging systems. [0009] 2. Related Art [0010] Biometrics is a science involving the analysis of biological characteristics. Biometric imaging captures a measurable characteristic of a human being for identity purposes. See, e.g., Gary Roethenbaugh, Biometrics Explained, International Computer Security Association, Inc., pp. 1-34, (1998), which is incorporated herein by reference in its entirety. [0011] One type of biometric imaging system is an Automatic Fingerprint Identification System (AFIS). Automatic Fingerprint Identification Systems are used for law enforcement purposes. Law enforcement personnel collect fingerprint images from criminal suspects when they are arrested. Law enforcement personnel also collect fingerprint images from crime scenes. These are known as latent prints. [0012] Tenprint scanners are a common type of AFIS system. Tenprint scanners produce forensic-quality tenprint records of rolled and plain impression fingerprint images. Typical tenprint scanners are usually custom-made consoles. Such custom-made consoles contain built-in equipment, such as a monitor, a keyboard, a pointing device, and at least one processor, for processing and viewing the fingerprint images. The custom-made consoles are expensive. [0013] Custom-made consoles are also burdened with high maintenance costs. When the console malfunctions, the entire system is inoperable. Tenprint scanner system owners must then place a service call to the manufacturer to have a technician come on-site and correct the problem. This can sometimes be a lengthy process. During such maintenance periods, tenprint records cannot be produced. [0014] What is needed is a tenprint scanner system that does not depend on an expensive, built-in console for processing and viewing fingerprint images. What is further needed is a system and method for interfacing a tenprint scanner system to a personal computer (PC) for processing and viewing fingerprint images, wherein the tenprint scanner system is not dependent upon any particular personal computer make or model. SUMMARY OF THE INVENTION [0015] The present invention solves the above mentioned needs by providing a system and method for interfacing fingerprint images from an identification system to a PC, wherein the PC contains a monitor, a keyboard, a pointing device, and processors for processing and viewing fingerprint images. The identification system is interfaced to the PC via a 1394 interface. The 1394 interface is a high performance serial bus that provides high speed data transfers. [0016] Briefly stated, the present invention is directed to 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. [0017] The present invention utilizes an off-the-shelf PC having a 1394 interface. The combination of an off-the-shelf PC and a 1394 interface provides a cost-effective way to process and view fingerprint images. The use of the PC also provides flexibility. Instead of having to call the manufacturer of the identification system when the PC malfunctions, a user can simply replace the malfunctioning PC with a back-up PC. The user also has the option of calling any PC service provider to maintain the PC. [0018] Further embodiments, features, and advantages of the present invention, as well as the structure and operation of the various embodiments of the present invention, are described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE FIGURES [0019] The accompanying drawings, which are incorporated herein and form part of the specification, illustrate the present invention and, together with the description, further serve to explain the principles of the invention and to enable a person skilled in the pertinent art to make and use the invention. [0020] FIG. 1 is a high level block diagram illustrating an Identification System according to an embodiment of the present invention.
