Photo Enrollment

Use a photo (from an identity document) to enroll the initial biometric data of the user

As introduced in the enrollment section:

enrollment is the process of registering a new user by connecting their facial biometrics to a Keyless account. During this process, a full and unobstructed view of the user's face is required.

If you possess a trusted source, such as an identity document, Keyless allows you to register a new user connecting their facial biometric from the identity document photo. The assumption behind the feature is that the identity document photo fulfills the requirement of a full and unobstructed view of the user's face.

To retrieve a document photo Keyless offers the Keyless Mobile Document SDK utility.

To enroll a user from the photo use the PhotoEnrollConfig.

// photoBitmap is the bitmap you created from the document photo.
val configuration = PhotoEnrollConfig(photo = photoBitmap)

Keyless.enroll(
  configuration = configuration,
  onCompletion = { result ->
    when (result) {
      is Keyless.KeylessResult.Success -> Log.d("KeylessSDK ", "Enroll success - userId ${result.value.keylessId}")
      is Keyless.KeylessResult.Failure -> Log.d("KeylessSDK ", "Enroll failure - error code ${result.error.code}")
    }
  }
)

// photoUIImage is the UIImage you created from the document photo.
let configuration = PhotoEnrollConfig(photo: photoUIImage)

Keyless.enroll(
  configuration: configuration,
  onCompletion: { result in
    switch result {
    case .success(let enrollmentSuccess):
        print("Enrollment finished successfully. UserID: \(enrollmentSuccess.keylessId)")
    case .failure(let error):
        print("Enrollment finished with error: \(error.message)
    }
  })

import 'package:keyless_flutter_sdk/keyless.dart';
import 'package:keyless_flutter_sdk/models/configurations/enrollment_configuration.dart';

// documentImage from eDocument.
final configuration = PhotoEnrollConfig(documentImage: documentImage);

try {
  final result = await Keyless.instance.enroll(configuration);
  print("Enrollment finished successfully. UserID: ${result.keylessId}");
} catch (error) {
  print("Enrollment finished with error: $error");
}

const config = new PhotoEnrollConfig({
  photoBase64: '<photoBase64>',
});

const result = await Keyless.enroll(config);
result.fold({
  onSuccess(data) {
    logConsole('Enroll result success ' + JSON.stringify(data, null, 2));
  },
  onFailure(error) {
    logConsole('Enroll result failure ' + JSON.stringify(error, null, 2));
  },
});

Photo Enrollment configuration

You can configure the enrollment process with optional parameters in your PhotoEnrollConfig() instance.

public data class PhotoEnrollConfig(
    public val photo: Bitmap,
    public val temporaryState: String? = null,
    public val operationInfo: OperationInfo? = null,
    public val jwtSigningInfo: JwtSigningInfo? = null
)

public struct PhotoEnrollConfig{
    public let photo: CGImage
    public let operationInfo: Keyless.OperationInfo?
    public let jwtSigningInfo: JwtSigningInfo?
    public let temporaryState: String?
}


 class PhotoEnrollConfig {
  public readonly photoBase64: string;
  public readonly operationInfo: OperationInfo | null;
  public readonly jwtSigningInfo: JwtSigningInfo | null;
  public readonly clientState: string | null;

Photo Enrollment success result

If the Enroll from photo is successful you will find in the EnrollmentSuccess containing the corresponding fields you requested during configuration.

data class EnrollmentSuccess(
    val signedJwt: String? = null,
) : KeylessSdkSuccess()

 class EnrollmentSuccess {
    public readonly keylessId: string;
    public readonly customSecret: string;
    public readonly enrollmentFrame: string | null;
    public readonly signedJwt: string | null;
    public readonly clientState: string | null;
 }

If the enrollment is successful the user is enrolled and can authenticate with Keyless from now on.
