Editors’ Introduction

It is our great pleasure to introduce the second issue of PoPETs, an open access journal that publishes articles accepted to the annual Privacy Enhancing Technologies Symposium (PETS). Articles submitted to this issue were reviewed by an Editorial Board of 66 members, who are internationally recognized researchers in the field of computer security and privacy. Starting with PETS 2015, the PET Board, which oversees PETS, decided to follow a hybrid conferencejournal model following in the footsteps of PVLDB. A hybrid model brings journal-style reviewing to conferences to improve the quality of papers as well as to provide more predictable, but rigorously peer-reviewed, paths to acceptance for authors. Authors can submit papers to multiple deadlines per year, when their work has matured to the point of submission, and decisions are provided at predictable schedules. Furthermore, papers that are rejected in one round are eligible for resubmission in subsequent rounds. Recognizing the need to increase the availability of the publication, PoPETs is now published under the open-access Creative Commons Attribution-NonCommercial-NoDerivs license. To avoid conflicts of interest, the editorial board membership was published before submissions were opened and authors were asked to identify members who should not review their paper. In addition editorial board members were asked to identify any conflicts of interest that authors did not list, and the editorial board chairs also checked for any missed conflicts. Editorial board members were welcome to submit papers, but the board chairs were not. There were 73 submissions to the second issue of PoPETs, each of which was assigned for review by 4 members of the editorial board. Where necessary external experts were recruited to review certain papers. The 6 submissions which were invited to resubmit after originally being reviewed for the first issue were re-
