minutiae - a Whatis.com definition (226 words) |
 | In the biometric process of fingerscanning, minutiae are specific points in a finger image. |
| The number and locations of the minutiae vary from finger to finger in any particular person, and from person to person for any particular finger (for example, the thumb on the left hand). |
| The precise locations of the minutiae are also recorded, in the form of numerical coordinates, for each finger. |
| Using 'minutiae' to match fingerprints can be accurate (303 words) |
| NIST conducted the study, called the Minutiae Interoperability Exchange Test (MINEX), to determine whether fingerprint system vendors could successfully use a recently approved standard* for minutiae data rather than images of actual prints as the medium for exchanging data between different fingerprint matching systems. |
| Minutiae templates are a fraction of the size of fingerprint images, require less storage memory and can be transmitted electronically faster than images. |
| However, the techniques used by vendors to convert fingerprint images to minutiae are generally proprietary and their systems do not work with each other. |
