Interface SharedBioTemplate

All Superinterfaces:

BioTemplate, Shareable

public interface SharedBioTemplate
extends BioTemplate, Shareable

The SharedBioTemplate interface provides the means for accessing unrestricted 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:

2.2.2

getBioType, getPublicTemplateData, getTriesRemaining, getVersion, initMatch, isInitialized, isValidated, match, reset

Modifier and Type	Method	Description
byte	getBioType()	Get the biometric type.
short	getPublicTemplateData(short publicOffset, byte[] dest, short destOffset, short length)	Get public part of the reference template.
byte	getTriesRemaining()	Returns the number of times remaining that an incorrect candidate template can be presented before the reference template is blocked.
