<p>A shoeprint identification system (10) comprises a central computer (12) including a central database (14) of known shoe types and key data applying to said shoe types, and crimes at which shoe imprints existed and key data applying to said shoe imprints. A plurality of remote identification units (18 are located in geographically spaced custody suites, each custody suite identification unit comprising a scanner (18) to scan a suspect's shoeprint image to produce a scanned image; a processor (48) to process the scanned image according to an algorithm to provide key data in respect of the scanned image; a custody unit database (46b) of known shoe types and key data applying to said shoe types; a custody unit database (46c) of crimes at which imprints of known shoe types existed; a comparator to compare the image key data against the key data in said custody unit database to provide one of three results: iv) no match; v) exact match; or vi) a number of possible matches, between said suspects' shoeprint image and said known shoe types. The custody suite databases (46a, b,c) are limited in the shoe types contained therein to sets of the shoe types typically worn by people in the local area of the custody suite and identified at local crime scenes, such that different custody suite databases include different data from each other and substantially less data than said central database.</p> |
