7. Design Principles to Integrate the FIDO Standards
• Integrate the FIDO standards in a straightforward manner
– Create and maintain the FIDO eco-system, and align with it for sustainability
• Utilize the FIDO standards as much as possible
– Allow different type of authenticators e.g. fingerprint sensors and iris scanner
• Protect users and ecosystem partners in consideration of security
– Follow the FIDO privacy policy, “Biometric template and private keys never
leave devices,”
– Realize that genuineness of authenticator shall be securely proven to servers,
– Keep the same security level of various devices from multiple OEMs, and
– Avoid to generate wrong perception in the market.
• Minimize the integration efforts, time and cost
– Gather FIDO-enabled service apps to a single point of I/F – d ACCOUNT to ASM
