May 2022 Summaries

Fingerprint, originally known as FingerprintJS, has changed its company name to better reflect its evolving product offerings, while maintaining its popular FingerprintJS library for JavaScript browser fingerprinting. The company, founded by Valentin with a focus on accurate identification to prevent online fraud, has expanded its product line to include the "Pro" device identification API for web and mobile applications and new open-source projects like BotD and AEV. Although the company's name has changed, the product names and Github libraries remain the same, ensuring continuity for customers. The name change does not affect service or implementation, requiring no action from customers, though users may need to re-enter passwords for the new domain, fingerprint.com. The company promises many exciting product updates in the future, underlining that the name change is primarily a cosmetic update to better align with customer and employee references to the company as "Fingerprint."

The iOS ecosystem is often seen as more secure compared to its competitors, yet it still requires robust fraud prevention measures. Apple provides several native frameworks, like DeviceCheck and DCAppAttestService, to enhance application security, though these tools often necessitate user involvement and are limited by their dependency on network communication with Apple's servers. The text discusses the challenges and limitations of using these APIs for device identification and highlights an alternative approach using local device fingerprinting, which combines various signals to create a stable and unique identifier without requiring user consent. An open-source library, Fingerprint for iOS, leverages this methodology by utilizing Vendor Identifier and Keychain Storage to generate a reliable device fingerprint, which improves stability across app reinstalls. This library is designed to operate without additional permissions or third-party data sharing, making it suitable for iOS App Store applications. The document also introduces a more advanced commercial version, Fingerprint Pro, which enhances the stability and reliability of device identification through additional signals and backend integration.
