How to Get Actual Privacy and Utility from Privacy Models: the k-Anonymity and Differential Privacy Families
Privacy models were introduced in privacy-preserving data publishing and statistical disclosure control with the promise to end the need for costly empirical assessment of disclosure risk. We examine how well this promise is kept by the main privacy models. We find they may fail to provide adequate protection guarantees because of problems in their definition or incur unacceptable trade-offs between privacy protection and utility preservation. Specifically, k-anonymity may not entirely exclude …

Securing Faith, Sacrificing Safety
Digital Risks of Faith-Based Content Filters Centralized filtering systems often collect user data to function, raising real privacy and security issues as they are often not properly secured or anonymized. It is a one-stop shop to comprise the security and safety of an entire religious community, and each member of

DH-EAC: Design of a Dynamic, Hierarchical Entanglement Access Control Protocol
We propose Dynamic, Hierarchical Entanglement Access Control (DH-EAC), a pure-quantum protocol for fair and anonymous allocation of scarce entanglement across wide-area quantum networks composed of many quantum LANs (QLANs). Prior Dicke-state-based pure-quantum MACs resolve contention by local measurements without classical signaling, but they mainly target a single QLAN under static conditions; extending them to wide-area, dynamic settings while avoiding post-selection reconciliation remains o…

Lattice-Based Dynamic $k$-times Anonymous Authentication
With the development of Internet, privacy has become a close concern of users. Anonymous authentication plays an important role in privacy-preserving systems. $k$-times anonymous authentication ($k$-TAA) scheme allows members of a group to be authenticated anonymously by application providers up to $k$ times. Considering quantum computing attacks, lattice-based $k$-TAA was introduced. However, existing schemes do not support dynamically granting and revoking users. In this paper, we construct t…

Content Anonymization for Privacy in Long-form Audio
Voice anonymization techniques have been found to successfully obscure a speaker's acoustic identity in short, isolated utterances in benchmarks such as the VoicePrivacy Challenge. In practice, however, utterances seldom occur in isolation: long-form audio is commonplace in domains such as interviews, phone calls, and meetings. In these cases, many utterances from the same speaker are available, which pose a significantly greater privacy risk: given multiple utterances from the same speaker, an…
