Device fingerprinting can be used to deter fraudsters from trying to break in and some other hacking cases. So what is Device Fingerprinting and how to get device fingerprint in javascript? If you do not know yet, let’s find out by reading the article below.
What is Device Fingerprinting?
Device fingerprinting is a method of identifying a device using a combination of properties provided by the device configuration and how the device is used. The attributes collected as data to build the fingerprint of the device may vary depending on the person building the fingerprint. Some of the most common properties include:
- The IP address
- HTTP request headers
- Plugins or fonts that the user has installed on their device
- The screen resolution of the device
- The battery information of the device
- The operating system that the visitor is using
- User agents
- Flash data
- VPN and browser information
- Type of web browser and browser version
- Time zone settings
- Language settings
While none of the above data is unique to a device, the probability that two devices have the exact same combination of properties is extremely small and statistically insignificant, so this method can be used to identify unique devices.
What is device fingerprinting used for?
It allows users to collect accurate and extensive mobile device fingerprints for Android and iOS, and collect real-time information about device information, operating system, location settings, timestamps, language, user agent, and more.
What is a fingerprint in JavaScript?
Online fingerprinting, browser fingerprinting is a tracking and identification method that websites use to associate an individual browsing session with a website visitor. Using Javascript, a large amount of data can be collected about a user's web browser and device.
how to get device fingerprint in javascript?
Device fingerprinting methods provide advertisers with a way to track consumer behavior across multiple browsers. They also allow banks to identify whether a request is coming from a trusted device or a system associated with fraudulent activity.
To create a fingerprint, instantiate a new instance of the ImprintJs class and call getFingerprint passing in a list of tests you wish to run. The getFingerprint method returns a javascript Promise which once all tests have run, returns the generated fingerprint.
Using Javascript, a large amount of data can be collected about a user's web browser and device. When you stitch this information together, they reveal a unique combination of information, forming each user's own "digital fingerprint."
So I hope now you will understand what Device Fingerprinting is and how to get device fingerprints in Javascript. FingerprintJS helps prevent fraud, spam and account takeover with its highly accurate browser fingerprinting service. Their JavaScript technology combines hundreds of signals within any browser to generate unique identifiers that can be used to detect unusual patterns of behavior.
