How to Use a Device Fingerprint API to Identify Visitors

Device fingerprinting is a technique to identify users based on their hardware and software configurations. This is done by analyzing the combination of various attributes, including browser type, operating system, and IP address. The result is a unique identifier for each device and user. It can be used for a variety of applications, such as identifying fraudulent behavior, showing more personalized advertisements, and verifying the identity of a user.

To identify a visitor, a website owner will place a cookie on a visitor’s computer. This is a useful feature, since it allows a business to track the activity of the visitor on the site. However, it is not always obvious to users whether or not they are being tracked. For example, a mobile phone’s browser may not display any tracking capabilities. But a cookie still holds important information, such as a visitor’s shopping cart history.

To analyze the most important piece of data, the site owner can employ the help of an API. One option is to rely on the SSO’s fingerprinting service, which is designed to allow sites to uniquely identify end users systems. Using this technology, the user’s fingerprint is derived from the details of their device as it is submitted to the SSO in a login request.

Other types of solutions use the device fingerprint to collect data about a visitor’s browsing behavior. These can include advertising networks that show ads based on the browser type and device of a visiting user. In addition, these services can use the fingerprint to detect suspicious devices and blacklist them from future visitors. Another option is to implement a multi-layered AI algorithm that can detect duplicate accounts and other high-risk activities.

Another useful feature is that the device fingerprint value is not consumed by the API. ThisĀ device fingerprint API is because it is stored in a database on the merchant’s server. If a visitor does not provide their fingerprint, the store will reject the content.

Some companies are taking advantage of this technology to provide a more accurate and reliable method of identifying a visitor’s computer. For instance, Fing uses proprietary technology to detect make, model, and category, and is compatible with both multi-platform and crowdsourced data.

A similar technique is the Web Cookie fingerprinting method. In this case, a visitor’s cookies are stored on the merchant’s server, and the site owner can then analyze the visitor’s cookies to determine the most relevant data.

Among the simplest implementations is to embed a small JavaScript snippet in a hidden form element. Alternatively, a developer can use a JavaScript function to perform the same task. After the user submits the element, the device ID is transmitted to the server via Ajax. This snippet is returned in the response.

When implementing the device fingerprinting functionality, it is imperative to have the following in mind. Having a device fingerprint is not enough; you also need to have a way to access it when the user needs it.
