Fingerprint's device intelligence platform for iOS devices.

Fingerprint's device intelligence platform is also available for iOS devices. Our device intelligence platform for iOS helps you to accurately identify the devices that interact with your mobile app and provides high-quality smart signals that will help you identify risky transactions before they happen.

To make integrations with mobile apps easier, we offer SDKs for apps built natively as well as for apps built using multi-platform frameworks (e.g. React Native).

A Fingerprint account is required to be able to use the Fingerprint Identification SDK in your mobile apps. If you do not have an account yet, please sign up for one.

Device Identifier

When the Fingerprint Identification SDK is integrated into your mobile app, it will collect several attributes from the device. With the help of these attributes and additional algorithms, Fingerprint is able to provide a unique device identifier (i.e. visitorId) for every device on which your app is installed.

When compared with browsers, the identification accuracy is better for mobile devices because we identify mobile devices using signals that have higher longevity than those used for identifying browsers. But there are scenarios where a visitorId does not persist.

For your reference, we have listed various scenarios where a visitorId will remain the same before and after and where a new visitorId will be created.

ScenarioWill I receive the same visitorId before and after?
The app or device is restartedYes. You will receive the same visitorId even after the app or device is restarted.
The app is uninstalled and re-installed againYes.You will receive the same visitorId even after the app is removed and installed again
The provisioning profile and/or the signing certificate of the app are changed.Yes. You will receive the same visitorId as long as the AppID remains the same before and after the change.
The device is jailbrokenYes. You will receive the same visitorId as before even after the device is jailbroken.
Lockdown mode is enabled on the deviceYes. You will receive the same visitorId as before even after lockdown mode is enabled on the device.
Reset device settings to their default valuesYes. You will receive the same visitorId as before even after one or more of the device settings are reset to their default.
The device is factory reset(i.e. all content and settings are erased).No. After the device is factory reset, a new visitorId will be generated.

iOS Smart Signals

Smart Signals are actionable device intelligence signals that help you to make informed decisions about the device and thus prevent fraud. These signals could be used as input to your machine learning models behind your fraud detection or risk mitigation engines. For example, when you know that a request is originating from a jailbroken device, you will be able to take additional precautionary security steps (e.g. multi-factor authentication).

For iOS, the following smart signals are available:

These smart signals are available as part of our Pro Plus and Enterprise plans. If you are interested in one or more of these signals, then please contact our support team to enable them for you. Signing up for an Enterprise plan does not automatically enable these signals.

Getting Started Guides

Our Getting Started guides are aimed at helping you to easily integrate our SDK with your apps.

Supported Versions

The minimum version that the iOS SDK for Fingerprint Identification supports is iOS 13, tvOS 15. Per Apple and Statista, this will allow your app to be compatible with a wide variety of active iOS devices.

As of May 2023, our SDK will allow your app to be compatible with more than 94% of the devices in the world.

Privacy Manifest File Requirements for App Store

During WWDC 2023, Apple introduced a new requirement where app and SDK developers must create privacy manifest files to declare the data that their app/SDK collects and the reasons for collecting this data. Accordingly, starting from v2.3.2, the Fingerprint Identification SDK for iOS will include a privacy manifest file. To learn more, please see Understanding privacy manifest files.

If you need assistance with creating privacy manifest files for your app or with submitting your apps to the App Store, then please contact our support team and we will gladly help you through the process.

FingerprintJS-iOS: Open-source identification library for iOS

We also provide a lightweight, open-source library called fingerprintjs-ios which is available to use for free by everyone. Our commercial SDK, Fingerprint Identification for iOS, is based on our well-maintained, free, open-source library.

Compared to the open-source library, our commercial SDK collects many more attributes from the device. It also uses advanced fingerprinting and matching algorithms to create a unique device identifier.

For your better understanding, here is a complete set of differences between our open-source library (fingerprintjs-ios) and our commercial SDK (fingerprint-ios-pro).


Fingerprint Identification for iOS

Core Features

Attributes collected from the device Basic
(e.g. OS, Model)
Advanced. Lot more attributes, in addition to those collected by the open-source library.
ID Type Device ID or a fingerprint that is a hash of the collected attributes A single visitorId that is computed using advanced fingerprinting and matching algorithms
ID Origin Attributes are processed only within the library. External servers are not involved. Attributes are processed on external servers

**In comparison to fingerprints, VisitorIDs are more accurate and stable identifiers because they are deduplicated, are processed further on the server, and utilize fuzzy matching. On the other hand, fingerprint hashes become unstable across time intervals greater than 2 weeks because they rely on an exact match of all browser attributes.
***The company, Fingerprint, in its role as data processor is compliant with GDPR, CCPA and SOC 2 Type II. It is also ISO 27001 certified. As a data controller, it is still your responsibility to be compliant with GDPR and CCPA and use the identification result for legitimate purposes.
