 (IoT) collect a myriad of personal information. Rather than
 viewing AI and HLT as problems for privacy, our aim is to
 “flip the script” and explore how AI and HLT can help meet
 users’ desires for privacy when interacting with computers.
 We also aim to explore how AI and HLT can help developers
 and regulators detect potential compliance issues. Overall,
 we focus on two research questions:
1. How can AI and HLT preserve or protect privacy in chal-
    lenging situations?
2. How can AI and HLT help interested parties (e.g., com-
    puter users, companies, regulatory agencies) understand
    privacy in the status quo and what people want?
    We received fifteen paper submissions, which were sub-
 ject to double-blind peer review by our program committee.
 Ten submissions were accepted pending minor revisions to
 address reviewer comments. Authors of the remaining five
 submissions were invited to submit abstracts and posters to
 be lightly reviewed by the organizers. Three of those five
