Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Captures biometrics data, compares it to an array of BiometricsInformationRecords, and then returns a rank ordered array of indexes.
public abstract int[] Identify (int maximumFalseAcceptRateRequested, int maximumFalseRejectRateRequested, bool falseAcceptRatePrecedence, System.Collections.Generic.IEnumerable<Microsoft.PointOfService.BiometricsInformationRecord> referenceBirPopulation, int timeout);abstract member Identify : int * int * bool * seq<Microsoft.PointOfService.BiometricsInformationRecord> * int -> int[]Public MustOverride Function Identify (maximumFalseAcceptRateRequested As Integer, maximumFalseRejectRateRequested As Integer, falseAcceptRatePrecedence As Boolean, referenceBirPopulation As IEnumerable(Of BiometricsInformationRecord), timeout As Integer) As Integer()Parameters
- maximumFalseAcceptRateRequested
- Int32
The requested FAR criterion for successful verification.
- maximumFalseRejectRateRequested
- Int32
The requested FRR criterion for successful verification.
- falseAcceptRatePrecedence
- Boolean
If both criteria are provided, this parameter indicates which takes precedence. falseAcceptRatePrecedence indicates that maxFARRRequested takes precedence; falseRejectRatePrecedence indicates that maxFRRRequested takes precedence.
- referenceBirPopulation
- IEnumerable<BiometricsInformationRecord>
A collection of BiometricsInformationRecord properties against which the Identify match is performed.
- timeout
- Int32
Maximum number of milliseconds to try a successful biometric capture before failing.
