Interface SharedBioMatcher

All Superinterfaces:

BioMatcher, Shareable

public interface SharedBioMatcher
extends BioMatcher, Shareable

The SharedBioMatcher interface provides the means for accessing unrestricted matching biometric functionality, e.g., the biometric matching functions. A biometric manager/server can implement this interface with a proxy to the public matching functions; thus giving a biometric client access to matching functions but not to the enrollment functions. Without this interface, the client could potentially cast a biometric reference to gain access to enrollment functionality and thereby circumvent security measures.

Since:

3.0.5

byte	getBioType()	Gets the biometric type.
short	getIndexOfLastMatchingBioTemplateData()	Gets the index of the last matching BioTemplateData.
short	getMaxNbOfBioTemplateData()	Gets the maximum number of BioTemplateData that can be enrolled in this BioMatcher.
byte	getTriesRemaining()	Gets the number of times remaining that an incorrect candidate can be presented before the BioMatcher is blocked.
short	getVersion(byte[] dest, short offset)	Gets the matching algorithm version and ID.
short	initMatch(byte[] candidate, short offset, short length)	Initialize or re-initialize a biometric matching session.
boolean	isInitialized()	Indicates whether this BioMatcher has been loaded with at least one BioTemplateData and is ready for matching functions.
