## Title
Microtagging motor vehicles for identification from a paint sample discovered during a criminal investigation

## Abstract

A vehicle microtagging system employs vehicle paint to assist in tracking vehicles used in criminal activity. Microscopic microtag particles mixed into vehicle paint contain unique alphanumeric code sequences. These particles are designed to be left behind at a crime scene, later to be recovered by law enforcement. When the microtag particles are recovered from a crime scene, law enforcement uses a simple UV light test and a magnification instrument to identify the unique alphanumeric code sequence within the microtag particles.

Small particles for tagging of objects to be identified comprise luminescent material plus other material which provides information indicia for tagging purposes. Included in the tagging particles are very small particles of magnetic material which is reflective both for the radiations which excite the luminescent material and also for the radiations generated by the excited luminescent material. The inclusion of the reflective magnetic particles introduces only a minimal decrease in the effectiveness of the luminescent material to provide a spotting or locating function. The particles may thus be located either by their luminescent response, or by magnetic pickup, or both. Inorganic species of these particles are especially useful for tagging explosives for post-explosion identification of the explosives.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The following discussion describes in detail one embodiment of the invention (and several variations of that embodiment). This discussion should not be construed, however, as limiting the invention to those particular embodiments, practitioners skilled in the art will recognize numerous other embodiments as well.

A residual sample 20 is processed by tag retrieval personnel 22, such as a law enforcement officer, and the unique alphanumeric sequence 24 is retrieved by means including one or more of an ultraviolet light and a magnification instrument. Each microtag 11 bears the same unique alphanumeric sequence 24, which is preferably the same as the vehicle identification number (VIN) assigned to the vehicle. Optionally, a database 30 correlates the unique alphanumeric sequence 24 with vehicle information profile 32, the database 30 accessible in order to retrieve vehicle information 32 about a vehicle for which the alphanumeric sequence 24 is known.

After the vehicle 14 is identified from the unique alphanumeric sequence 24 in the residual sample, the hit and run driver 34 can be apprehended and arrested by law enforcement personnel 36.
FIG. 7 is an illustrative view of the present invention 10 in use. The present invention provides a method for marking a vehicle comprising the steps: a) providing a vehicle microtagging system having paint 12 for applying to a vehicle 14 and a plurality of microtags 11 dispersed in the paint, each microtag bearing the same unique alphanumeric sequence; and b) applying the paint to a vehicle, for example by means such as with a paint sprayer 34, applied by a vehicle painter 36.
FIG. 8 is a block diagram of a method of microtagging a pre-existing motor vehicle. The present invention provides for elective microtagging of existing motor vehicles comprising the steps of selecting an existing motor vehicle for microtagging, as shown in S1. In step S2, the vehicle's identification number is recorded onto a plurality of microtags and a liquid medium is selected, which may be a paint pigment or clear coat, as shown in step S3. In step S4 the microtags are combined with the liquid medium to form a sprayable mixture that is applied to said motor vehicle, as shown in step S5. Once the motor vehicle has been microtagged through application of the microtagged mixture, the vehicle registration bureau is notified, shown in S6, so that the bureau's database can be updated indicating that the vehicle has been microtagged, as shown in step S7.
FIG. 9 is a block diagram of a method of microtagging new motor vehicles. The present invention provides that microtagging new motor vehicles will encourage vehicle operators to be more responsible in their operation. In step S10, a motor vehicle is selected for microtagging and a visual indicator is added to the identification number, preferably a suffix letter such as ‘M’, as shown in step S11. In step S12, the vehicle's identification number is recorded onto a plurality of microtags and a liquid medium is selected, which may be a paint pigment or clear coat, as shown in step S13. In step S14 the microtags are combined with the liquid medium to form a sprayable mixture that is applied to said motor vehicle, as shown in step S15. Once the motor vehicle has been microtagged through application of the microtagged mixture, the vehicle registration bureau is notified, shown in S16, so that the bureau's database can be updated indicating that the vehicle has been microtagged, as shown in step S17.
FIG. 10 is a block diagram of a method of producing an encrypted microtag for a motor vehicle. The present invention envisions that there may be circumstances where the identity of vehicles used within a government agency require anonymity for national security purposes. Therefore, the present invention provides for encoding or encrypting the vehicle identification number. In step S20, a motor vehicle is selected for microtagging and the vehicles identification number is encrypted using a predetermined algorithm as shown in step S21. In step S22, the vehicle's identification number is recorded onto a plurality of microtags and a liquid medium is selected, which may be a paint pigment or clear coat, as shown in step S23. In step S24 the microtags are combined with the liquid medium to form a sprayable mixture that is applied to said motor vehicle, as shown in step S25. Once the motor vehicle has been microtagged through application of the microtagged mixture, the vehicle registration bureau is notified, shown in S26, so that the bureau's database can be updated indicating that the vehicle has been microtagged, as shown in step S27.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
