from connected profiles in a network.

The stemming of information availability from the network connection patterns, is taken into consideration starting from the observation that a single node is not only affected by its alters (i.e. its neighbours) but also by the alters of its alters [@cerqueti2018new]. We therefore make use of some related network measures, and in so doing we provide several brand-new measures, shifting from the concept of value to the concept of information patrimony, both at the node and network levels.

The aim of the present paper is not to provide a methodology aimed to set different prices for different users, but rather to shed some light on how network systems could potentially provide a greater amount of information than expected.

The paper is organised as follows: Section \[recsystems\] offers an overview of the evolution of profiling techniques. Section \[networkprop\] provides a review of network properties and their impact on profiling techniques. Section \[theory\] is devoted to the outline of certain relevant notations about network theory. Section \[NIP\] introduces and discusses our proposal and the related interpretation. Section \[example\] shows some explanatory simulations. The final section offers some conclusive remarks and proposes directions for future research.
