Client fingerprinting techniques enhance classical cookie-based recognition mechanisms in the domain of web-based user tracking. A unique identifier is created based on characteristic attributes of the client device and then used for deployment of personalized advertisements, price differentiation or fraud detection. Such identifiers can also be used in authentication scenarios as a user's or device's fingerprint. Whereas fingerprinting performs well for highly customized devices, these methods often lack in precision for highly standardized devices like mobile phones. Depending on the use case, the development of tailor-made recognition mechanisms is required. Fingerprinting of web clients is often seen as an offence to web users' privacy as it usually takes place without the users' knowledge, awareness, and consent.
