Step-up AuthN & identification (portal high risk transaction)
Portals sometimes have “high-risk” transactions defined by them, which require higher level of security clearance than the regular login. HSID Aikyam EDA offers Step-up authentication (AuthN) and Identification mechanism, by utilizing the standard OIDC protocol and acr_values parameter.
Currently Step-up AuthN & Identification offers
- Authentication methods
- Identification methods
When portal owners utilize this feature, please understand the following scope of this capability:
Common rules for all methods above:- Step-up AuthN & Identification does not know the definitions of “high-risk” transactions. Each portal defines their “high-risk” transaction, and when the user is about to perform “high-risk” transaction, request Step-up AuthN to HSID Aikyam EDA.
- Step-up AuthN & identification does not manage whether the user went through “high-risk” transactions in the same HSID authenticated session. Portal needs to control whether they want to perform Step-up AuthN & Identification for every high-risk transaction, or, want to suppress it if the user went through high-risk transaction in the same portal session previously. This suppression policy is completely up to the portals.
- At the time of Step-up AuthN & identification, if HSID authentication session is expired or authentication cookie is not available, the user is prompted the login page and goes through the login process first, then Step-up AuthN & Identification is performed. In order to avoid the session expiration or unavailability, please use Aikyam Web SSO V2 endpoint, explained in Aikyam Web SSO V2 section.
HSID MFA / PBIC:- HSID MFA / PBIC does not consider the fact whether the user went through HSID MFA (i.e. Phone OTP) / PBIC at the time of the login. Step-up simply performs HSID MFA or PBIC method when it is asked by the portal.
HSID AAL2: - HSID AAL2 considers the fact whether the user satisfied AAL2 (i.e. passkey AuthN or password + Phone OTP AuthN) at the time of the login or anytime in the unexpired HSID authenticated session. Only when the authenticated session does not satisfy AAL2, Step-up AuthN performs an additional authentication to satisfy AAL2.
HSID IAL2:- HSID IAL2 considers the fact whether the user satisfied IAL2 (i.e. Document Based Identity Confirmation – utilizing LexisNexis IDVerse and Flex ID) anytime during HSID account lifetime. Only if the user never satisfied IAL2 during their HSID account lifetime, Step-up Identification performs an additional identification to satisfy IAL2.
HSID IAL1 document verification: - HSID IAL1 document verification considers the fact whether the user satisfied this verification anytime during HSID account lifetime, same as IAL2 above.
HSID IAL1 phone verification:- HSID IAL1 phone verification considers the fact whether the user satisfied this verification anytime during HSID account lifetime, same as IAL2 above.
