Attributes in device fingerprinting

  • Статья

The following tables show the device fingerprinting attribute categories that we try to collect for web, iOS, and Android. The description of the attributes explains how each helps detect fraud. If your organization has specific needs, and you want some categories of data not to be processed by Fraud Protection, reach out to customer support before onboarding. Customer support can help you do the configuration correctly to meet your privacy needs.

Attribute list for iOS

Category Name Description of the attribute
Accelerometer Accelerometer Data Time Stamp Time at which the accelerometer data is valid.
Accelerometer Accelerometer Data Accelerometer reading [X-axis, Y-axis, Z-axis].
Derived Attributes Device ID Device ID derived from device attributes.
Device Specification Active Processor Count Number of active processing cores available on the device.
Device Specification Advertising ID Alphanumeric string unique to each device, used only for serving advertisements. In iOS 10.0 and later, the value of the Advertising ID is all zeroes when the user has limited ad tracking. Unlike the identifierForVendor property of the UIDevice, the same value is returned to all vendors. This identifier may change if, for example, the user erases the device. For this reason, you shouldn't cache it.
Device Specification Allows VOIP Indicates if carrier allows VOIP calls to be made on its network.

Device Specification Identifier For Vendor UUID that may be used to uniquely identify the device. This is the same across apps from a single vendor. The value of this property is the same for apps that come from the same vendor running on the same device. A different value is returned for apps on the same device that come from different vendors, and for apps on different devices regardless of vendor. Normally, the vendor is determined by data provided by the App Store. If the app wasn't installed from the app store (such as enterprise apps and apps still in development), then a vendor identifier is calculated based on the app’s bundle ID. The bundle ID is assumed to be in reverse-DNS format.

Interpreting fingerprinting response to detect VPNs

There are two fields that exist in the Account Create, Account Login, and Purchase API response that can be used to identify VPNs:

  • Proxy: A boolean indicating if Fraud Protection detected a proxy or not.

  • ProxyType: An enum. The following table provides the enum values for each ProxyType.

    ProxyType Description
    http The proxy uses the HTTP protocol and has open ports, which are accessible by any Internet user.
    service The proxy is operated by an organization (often for profit) that provides access to subscribers as a service. The proxy is one of an array of proxies (often internationally distributed) that are part of a Virtual Private Network (VPN) that subscribers connect to by installing an application. The network may have different proxy locations or bandwidth options depending on the user’s membership level, whether it's paid or free.
    socks The proxy uses the Socket Secure (SOCKS) protocol and has open ports, which are accessible by any Internet user.
    socks http The proxy has both the HTTP and SOCKS protocols set up and has open ports, which are accessible by any Internet user.
    tor The proxy is part of the onion router (Tor) network. Encrypted user Internet traffic is routed through a regularly changing series of nodes operated by volunteers.
    unknown The proxy’s type couldn't be determined.
    web The proxy operates by using an Internet web browser. Navigate to the web proxy website, enter the URL of the site you wish to visit, and the contents of the requested URL are returned by the web proxy website within the browser.

For example, to identify a VPN, Proxy would be TRUE and ProxyType would be service.
