Fingerprint Identification- FBI carries 198 million fingerprints on record
- Used for unique identification of a person
- First gained credibility when used to identify William West, who looked almost physically identical to a man named Will West (another inmate). The guards used fingerprints to successfully differentiate between the two prisoners.
-To more closely identify a fingerprint, the ends of the swirls (minutiae) are mapped.
-The distances between minutiae are stored using a Euclidean algorithm or what the FBI uses (D9/7 wavelet based system)
This allows for quick fingerprint identification
Some verification is required to check for error (recall fingerprints
being rotated)
