3 heat type: by identifying that the different temperatures of Fingers wrinkle ridge paddy completes fingerprint image and obtains.
Current most sensor points whether ground connection or have finger venous image to determine whether real finger by detecting, so cannot judge that the fingerprint sleeve after improvement (mixes partially conductive material, according to the silica gel sheath that fingerprint image is made, silica gel sheath leaves fine and smooth fingerprint lines) deception.
The effect that triple checking can realize:
Existing transaction system often occur the account of user and password stolen after cause the situation of property loss, user and financial institution all can suffer loss in various degree.And use triple checking just can avoid this kind of situation afterwards.First: the registered fingerprint of the corresponding client that ordinary person cannot obtain easily.Secondly: even if the password of client is revealed, but verify due to registered fingerprint cannot be obtained.Again: even if the fingerprint of client and password are revealed simultaneously, so dynamically challenge code also will effectively stop transaction to be carried out.So triple checking effectively can solve the worry of current financial sector, even if the effect of user owner can be determined.Triple verification the verifying results of native system are better than existing transaction system.
Further, payment terminals 1 is sent to server 2 after receiving payment cipher data;
Server 2 judges that whether payment cipher data are correct;
If so, be then verified;
If not, then payment terminals 1 is returned the result to.
