The device fingerprint identifies devices through information collected by a client run on an end user’s computer.
This client generates a black box that contains all device information available.
Black box content
A black box will typically:
- Range up to 4,000 bytes (the average length being just under 1,000
- Contain alphanumeric values and the special characters: + / ; =
- Begin with 0200, 0400, 0500 or 0600
Generate black box content
This adds the black box as another field to be
submitted along the other details in the form.
|You MUST...||You MUST NOT...|
1. Include a hidden form field with an ID “ioBB” that will be populated with the value.
Example black box generation
