Enrollment
Enrollment creates a Keyless account. You can think of "enrollment" as a "register/signup" process. During the enrollment Keyless ties the user's face biometrics to the Keyless account.
For the enrolment, a full face image is required and the process cannot be completed if any occlusion is present, e.g. a face mask.
Enrollment builder methods
You can customize the enrollment with optional methods from the EnrollmentConfiguration
builder. The full EnrollmentConfiguration
is available below:
Enrollment success result
Depending on the builder methods you enable, Keyless will populate the corresponding fields in the EnrollmentSuccess
result reported below. Not all builder methods produce a result as output that is why you have less fields in output than the number of methods of the builder.
Custom secret
it is possible to protect with the user's face biometrics a "secret" that you provide as input.
Depending on your application logic, you can choose to use different secrets.
Your custom secret could be a secret that you have provided to the app from the backend, the seed of an OTP protocol, or anything else. If you only need to know just the result of the authentication (success/failed), you can provide any constant value as token.
Keyless accepts only ASCII strings as custom token.
Using the savingSecret
method you can specify an ASCII string to store securely with Keyless. You can retrieve the secret later on after a successful authentication.
Backup Retrieval and Recovery
Keyless can generate backup data useful to recover an account.
You are responsible to store the backup data securely.
To retrieve the backup data use retrievingBackup
method. Once the enrollment succeeds you can read the backup data in the EnrollmentSuccess
result.
To recover and account you can enroll with backup data that you retrieved and stored in the past. To recover an account use withBackup
passing as parameter the backup data.
Liveness Settings
Using withLivenessSettings
you can specify the liveness security level choosing the options from LivenessConfiguration
.
You can also specify a timeout
(in seconds) to cancel the enrollment if the liveness takes longer than the timeout.
Operation info
withOperationInfo
specifies an operation identifier and payload stored on the Keyless backend if the enrollment succeeds.
Each operation id must be unique, you will get an error if you re-use the same operation id.
Details on how to query our backend for stored operations are available on Operations API.
Enrollment Delay
Using withDelay
you can specify the delay (in seconds) to delay the liveness start. The camera preview appears but the liveness processing waits for the specified delay before starting.
Enrollment Selfie
Only available to some customers. If you are not eligible you will get an error.
Using withEnrollmentSelfie
you can retrieve the image from which Keyless computes the biometrics of the user. The image can be found in the EnrollmentSuccess
result.
Temporary State
If you enrolled users from a different source than the mobile SDK (e.g. Keyless Agent), you need to sync the mobile SDK with the state returned by the Keyless Agent.
To synch the mobile SDK enroll providing the "temporary state" or "shared state". Specify withTemporaryState
in the EnrollemntConfiguration builder.
The UI is the UI for the authentication even if you called an EnollmentCondifuration. This is expected since from the user perspective the enrollment was already performed previously.
