Dynamic Recognition of Speakers for Consent Management by Contrastive Embedding Replay.

Voice assistants overhear conversations, and a consent management mechanism is required. Consent management can be implemented using speaker recognition. Users that do not give consent enroll their voice, and all their further recordings are discarded.

Extracting random numbers from quantum tunnelling through a single diode.

Random number generation is crucial in many aspects of everyday life, as online security and privacy depend ultimately on the quality of random numbers. Many current implementations are based on pseudo-random number generators, but information security requires true random numbers for sensitive applications like key generation in banking, defence or even social media. True random number generators are systems whose outputs cannot be determined, even if their internal structure and response history are known.

Using Quantum Confinement to Uniquely Identify Devices.

Modern technology unintentionally provides resources that enable the trust of everyday interactions to be undermined. Some authentication schemes address this issue using devices that give a unique output in response to a challenge. These signatures are generated by hard-to-predict physical responses derived from structural characteristics, which lend themselves to two different architectures, known as unique objects (UNOs) and physically unclonable functions (PUFs).
