Digital Signage Personalization for Smart City: Major Requirements and Approach

Abstract

Providing information in smart cities is possible in various ways. Digital signage is one of such options. However, personalization and contextualization of digital signage is complicated due to both technological and legislative reasons. When providing contextual information to a group of users, consideration of preferences and interests of users is complicated by a number of additional problems, most of which are related to identifying preferences/interests common to this group of users, as well as to their confidentiality. At the moment, such solutions do not exist. The paper presents a methodology of building a personalized digital signage system taking into account confidentiality and using tacit feedback to clarify the information provided, as well as information about users.
