Liveness Detection

This section contains the necessary knowledge to understand the Liveness engine in BiometridStandard.

BiometridStandard.getInstance().startLivenessDetection(data: data, customization: customization, i18n i18n, viewController: self, callback: self)

Parameter	Description
data: [String: Any]?	Data if is necessary to pass information from other step
customization: Face01WrapperCustomization?	Class to change layout customization
i18n: [String: String]?	Json with keys and values to override texts of liveness layout
viewController: UIViewController	View Controller to open the liveness engine
callback: ProcessCallback	callback

Implementation example

import UIKit
import BiometridStandard

class ViewController: UIViewController, ProcessCallback {
    
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    
    @IBAction func startLivenessDetectionBtn(_ sender: Any) {
        let data: [String: Any] = ["front": "base64",
                                   "back": "base64",
                                   "doctype": "idcard"]
        let i18n: [String: String] = ["FaceTec_action_ok": "OK",
                                      "FaceTec_action_im_ready": "I'm Ready"]
        let customization = Face01WrapperCustomization()
        customization.showBrandingImage(true)
        BiometridStandard.getInstance().startLivenessDetection(data: docBuilder, customization: customization, i18n: i18n, viewController: self, callback: self)
    }
    
    func livenessResultCallback(response: LivenessResponseDetails?, error: Errors?) {
        if error != nil {
            print(error?.rawValue)
            return
        }
        print("response", response)
    }

    func livenesStateCallback(state: LivenessState, error: Errors?) {
        if error != nil {
            print(error?.rawValue)
            return
        }
        print("state", state)
    }
}

Callback params

response: LivenessResponseDetails?	Object with the session id, face scan and auditTrail
error: Errors?	Errors associated enum
