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 the available device information.
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 following special characters: + / ; =
- Begin with 0200, 0400, 0500 or 0600
Generating black box content
This adds the black box as another field to be submitted along with the other details in the form.
|What TO DO
