SampleBioServer

• java.lang.Object
  • Applet

Fields Summary
public static final byte	CLA
public static final byte	INS_ENROLL
public static final byte	MATCH_TRY_LIMIT
private OwnerBioTemplate	impl

Constructors Summary
protected SampleBioServer(byte[] bArray, short bOffset, byte bLength) Only this class's install method should create the applet object. byte aidLen = bArray[bOffset]; if (aidLen== (byte)0){ register(); } else { register(bArray, (short)(bOffset+1), aidLen); } impl = BioBuilder.buildBioTemplate(BioBuilder.PASSWORD,MATCH_TRY_LIMIT);

Methods Summary
public void	enrollData(APDU apdu) method takes in the data This implementation assumes that all the password data is given in the enroll method. byte []buffer = apdu.getBuffer(); short bytesRead = apdu.setIncomingAndReceive(); impl.init(buffer, ISO7816.OFFSET_CDATA, bytesRead); impl.doFinal(); //enrollment complete
public byte	getBioType() return impl.getBioType();
public short	getPublicTemplateData(short publicOffset, byte[] dest, short destOffset, short length) return impl.getPublicTemplateData(publicOffset,dest,destOffset,length);
public Shareable	getShareableInterfaceObject(AID clientAID, byte parameter) return this;
public byte	getTriesRemaining() return impl.getTriesRemaining();
public short	getVersion(byte[] dest, short offset) return impl.getVersion(dest,offset);
public short	initMatch(byte[] candidate, short offset, short length) return impl.initMatch(candidate,offset,length);
public static void	install(byte[] bArray, short bOffset, byte bLength) Installs this applet. param bArray the array containing installation parameters param bOffset the starting offset in bArray param bLength the length in bytes of the parameter data in bArray new SampleBioServer(bArray,bOffset,bLength);
public boolean	isInitialized() return impl.isInitialized();
public boolean	isValidated() return impl.isValidated();
public short	match(byte[] candidate, short offset, short length) return impl.match(candidate,offset,length);
public void	process(APDU apdu) Processes an incoming APDU. see APDU param apdu the incoming APDU exception ISOException with the response bytes per ISO 7816-4 byte buffer[] = apdu.getBuffer(); // check SELECT APDU command if(selectingApplet()) return; switch (buffer[ISO7816.OFFSET_INS]){ case INS_ENROLL: enrollData(apdu); break; default: ISOException.throwIt(ISO7816.SW_INS_NOT_SUPPORTED); }
public void	reset() impl.reset();
