Dear all, We have submitted a research paper entitled "Privacy Enhancing Technologies for solving the Privacy-Personalization Paradox" that has been very recently accepted to the highly ranked Journal of Network and Computer Applications 2020. The file which is 1.5Mo is temporary available on: https://filesender.renater.fr/?s=download&token=efafad0d-72ac-420b-b466… <https://filesender.renater.fr/?s=download&token=efafad0d-72ac-420b-b466-e0e83bbc3fba> Abstract: Personal data are often collected and processed in a decen- tralized fashion, within different contexts. For instance, with the emer- gence of distributed applications, several providers are usually correlat- ing their records, and providing personalized services to their clients. Collected data include geographical and indoor positions of users, their movement patterns as well as sensor-acquired data that may reveal users’ physical conditions, habits and interests. Consequently, this may lead to undesired consequences such as unsolicited advertisement and even to discrimination and stalking. To protect users’ privacy, several tech- niques emerged, referred to as Privacy Enhancing Technologies, PETs for short, aiming at providing privacy preserving personalized ser- vices i.e., recommendation services, web-search systems and pervasive applications.This paper identifies a taxonomy classifying eight categories of PETs into three groups, and for better clarity it considers three categories of per- sonalized services. After presenting the main features of PETs with illustrative examples, the paper points out which PETs best fit each person- alized service category. Then, it discusses some of the inter-disciplinary privacy challenges that may slow down the adoption of these techniques, namely: technical, social, legal and economic concerns. Finally, it pro- vides recommendations and highlights several research directions. Please find the pre-final version of our paper attached to this email. If the dissemination committee raises no objections, we would like to acknowledge the SPARTA project.
