1 Match On Card Technology and its use for PKI Mgr. Miroslav Valeš Sales Manager Eastern Europe May 9, 2001 CATE 2001 Security and Protection of Information

2 Slide 2 CATE Security and Protection of Information Presentation Outline The problem of adding biometrics to smartcards How Match On Card (MOC) solves it The Potential Impact of MOC MOC specifications MOC in PKI applications Alternatives to MOC Summary and Conclusions

3 Slide 3 CATE Security and Protection of Information Biometric data cannot be kept private PC is not secure PIN still necessary to unlock card No way to add stronger security than PIN Enrolled Biometric Data Operating System Private ROM Data Readable Public Data Smart Card Host PC SC Reader FP Processing SW FP template Match Y/N The Problem of Adding Biometrics to Smartcards

4 Slide 4 CATE Security and Protection of Information Fingerprint Background Scan raw imageLocate minutiaeTemplate showing geometric relationship between minutia points is stored Minutiae data are unique and are the fingerprint processing standard

5 Slide 5 CATE Security and Protection of Information Recognition Technology Minutiae detection Bifurcation Ridge Ending 2 fingers not more than 7 matching min. Usual fingerprint has around min. Comparison - relative position of minutiae Allows rotation and translation 2,5 Kb template created (50 bytes per minutiae)

6 Slide 6 CATE Security and Protection of Information Template generated on PC is matched on card Fingerprint template never leaves the smart card Card not unlocked unless finger matches Can be PIN supplement or replacement Still need to trust the reader or PC MOC Operating System Private ROM Data Private FLASH Data Smart Card Host PC SC Reader FP Processing SW FP template Enrolled Biometric Data MOC System using PC

7 Slide 7 CATE Security and Protection of Information The Potential Impact of MOC Smart cards become easier to use (PIN replacement) Finally have a way to securely tie the card to its owner The user privacy is secured (users biometric data will never leave the card)

8 Slide 8 CATE Security and Protection of Information Software program running on smartcard Designed for 8-bit low-cost smart cards 120 lines of C-code Object code < 2Kbytes RAM < 64 bytes Verification time 0.5 sec / successful match 2 sec / unsuccessful match Templates use about 2.5Kbytes / finger Uses non-proprietary input features (minutiae) MOC Specifications

9 Slide 9 CATE Security and Protection of Information Standalone MOC System All fingerprint processing on card with FP sensor on reader MOC Operating System Private ROM Data Private FLASH Data Smart Card Host PC FP Processing Firmware Signed FP template Enrolled Biometric Data Smart SC & FP Reader Challenge/Response

10 Slide 10 CATE Security and Protection of Information Fingerprint used to authorize operations with the users private key Smartcard securely stores: Users digital certificates Associated private keys The biometry guarantees who is using the smartcard MOC in PKI Applications: PKI + Smartcards + Biometry

11 Slide 11 CATE Security and Protection of Information Alternatives to MOC: PIN only (current systems) Benefit: status quo costs nothing to implement Drawbacks: Cant tie user to card. Does not provide strong security. Process-On-Card Everything-On-Card

12 Slide 12 CATE Security and Protection of Information Alternative to MOC: PROC Process-On-Card: all fingerprint software, including image processing, runs on card Signed FP images are sent into card from the reader Higher cost (likely needs 16 or 32 bit card to work reliably) Not much more secure than MOC (still have to send in signed biodata)

13 Slide 13 CATE Security and Protection of Information Alternative to MOC: EVOC Everything-On-Card: sensor and all FP software runs on card Very secure but very expensive All sorts of production issues Smartcard durability, flexibility, etc.

14 Slide 14 CATE Security and Protection of Information Summary and Conclusions MOC is the first secure way of adding fingerprint security to smart cards MOC can replace or supplement the PIN MOC adds encryption capabilities and PKI to the biometrics Thanks to the encryption support biometry can now be integrated into complex security applications: File encryption, digital signatures, remote authentication, VPNs, …
