What is Digital Fingerprinting?
What kind of information can be obtained from a device to “make it unique”?
By means of a pixel installed on the web, such pixel can read, detect or analyze fields such as:
- Operating system, version…
- Screen size and resolution
- Browser and browser version.
- Installed plugins.
- …
This technology takes in mind all this data and generates a unique device ID. This device ID works as a cookie-id, but without cookies.
The probability that two users have the same version of Windows AND the same version of Browser AND the same plugins is remote.
Visit the EFF.org website to analyze how unique your fingerprint is.
This system, like others based on the same technology, bases its tracking on creating a user-id to measure what you do.
The ePrivacy regulation indicates that even if we anonymize data as much as possible, being impossible to associate with a person if we measure individually, it does not comply with ePrivacy.
So remember, measuring anonymously doesn’t mean that you are in compliance with the regulation.
