VerifyMatch

Description

Verifies the similarity between two fingerprints.

Applies to

BiometricScanner objects

Syntax

Integer scanner.VerifyMatch ( candidate, template, {FARAchieved})

Argument	Description
scanner	The scanner object associated with the device you want to use to complete a scan
candidate	Blob value for the current minutiae data that you want to compare
template	Blob value for a stored minutiae record
FARAchieved	Integer value, passed by reference, for the false acceptance rate of the most recent scan

Returns

Integer. Returns 1 for a successful match within the specified FAR/FRR ratio. A return value of -14 indicates that the comparison value falls outside this ratio. For a list of all possible errors and their definitions, see ScanCapture.

Usage

Call VerifyMatch to compare two fingerprint scans. Typically the result of a current candidate scan is compared against a fingerprint scan stored in a database. The scan stored in the database is also known as a template scan.

Examples

Example 1

The following example compares the scanned data against a local variable with a blob datatype:

li_rtn = l_bioscanner.VerifyMatch (lb_MinutiaeFromScan, lb_MinutiaeFromTemplate)
