Emergent Privacy Norms for Collaborative Systems

A Model for Governing Information Sharing in Smart Assistants

“…Extracting privacy norms, as we have done in our experiment, can also be done in other ways. In [56], the authors extracted the norms from multi-agent social simulations and showed how these norms can be used to make privacy decisions. In [57] they have extended the approach to show that access control can also be managed by norms.…”

Norm-based Access Control

“…This paper describes the principles of norm-based access control and develops an approach named Prinor where access control decisions can be taken based on the norms that are generated from the previous privacy decisions in the system. We represent the different privacy norms in OSNs using Tuomela's categorization [36] and develop algorithms to identify these norms in a given system. The usage of the algorithms enables users to choose between enforcing personal privacy settings and following the norms in the system.…”

Privacy in Collaborative Systems

“…Tuomela further divides social norms to r-norms (rule norms) and snorms (social norms), and personal norms to m-norms (moral norms) and p-norms (prudential norms). We adopt this classification to model privacy expectations as norms and formally represent it similar to existing formalisms [9,65,108], such that a set of preconditions determine the activation of a sharing action to be taken. We also aim to handle context-based privacy preferences [10] with our norm definitions.…”

“…Norms have been studied in multiagent literature. Our earlier work investigated the idea of social norm emergence for OSNs [108]. However, it did not consider important aspects including prudential norms, aging of privacy decisions, or agent's autonomy in choosing to follow norms.…”
