06

This value means that the merchant attempted to authenticate the cardholder, but either the cardholder or issuer was not participating. The value should be returned by the ACS in the Authentication Response message for an Attempt Response. Additionally, merchants may use an ECI 6 in the authorization request when a Verify Enrollment of N is received from the Visa Directory Server

07

This value is set by the merchant when the payment transaction was conducted over a secure channel (for example, SSL/TLS), but payment authentication was not performed, or when the issuer responded that authentication could not be performed.
