Claim One:
1. A method comprising: (A) monitoring user interactions that a user performs via an input unit of an electronic device, when the user interacts with a computerized service that utilizes communication between said electronic device and a remote server; (B) extracting from the monitored user interactions, a behavioral biometric model that characterize said user interactions; (C) storing in a remote database, that is external to said electronic device, a record indicating (i) the extracted behavioral biometric model of said user, and (ii) a unique identifier; (D) generating, and storing internally within said electronic device, a behavioral biometric cookie data-item that reflects an association between: (I) said user, and (II) said record reflecting the extracted behavioral biometric model that is stored in said remote database; (E) storing said behavioral biometric cookie data-item, internally within said electronic device; wherein the method comprises: generating a conventional HTTP cookie that tracks browsing history of all human users of said electronic device; generating a first behavioral sub-cookie data-item that selectively tracks only browsing history of a first human user of said electronic device; generating a second behavioral sub-cookie data-item that selectively tracks only browsing history of a second, different, human user of said electronic device; classifying a current usage session of the electronic device, as belonging either to the first human user or to the second human user, based on user-specific behavioral attributes that are extracted from current user interactions via the input unit of the electronic device.
