Privacy Protection from Sampling and Perturbation in Survey Microdata
, 2010 We consider the assessment of disclosure risk in the release of microdata from social surveys as public-use files. We consider both identification risk and the notion of differential privacy introduced in the computer science literature.

Hierarchical Physical‐Cyber Encryption via Metasurface‐Encoded Holographic Keys
Advanced Science, EarlyView.ABSTRACT Physical‐layer encryption based on metasurfaces has emerged as a promising alternative to conventional algorithmic cryptography by embedding security into physical processes. However, most existing metasurface‐based encryption schemes operate within single‐stage or static frameworks, where correct physical illumination directly reveals the ...

Advanced Science, EarlyView.A soft hybrid multi‐wavelength PPG wearable acquires neonatal signals. Synchronized PPG and invasive ABP data are segmented into fixed windows. A 1D‐EfficientNet model predicts segment‐level SBP and DBP. Model performance is examined with retrospective subgroup analysis across acquisition conditions.

LBS-oriented location privacy protection model and scheme
Tongxin xuebao, 2014 A location privacy protection model was proposed based on the central server structure, designed a location privacy protection scheme based on pseudo-random permutation for the model. Proposed scheme builds on k-anonymous and secret information retrieval

Practical privacy and security for opportunistic networks [PDF]
, 2014 When in physical proximity, data can be directly exchanged between the mobile devices people carry - for example over Bluetooth. If people cooperate to store, carry and forward messages on one another's behalf, then an opportunistic network may be formed,

Advanced Science, EarlyView.Green and scalable synthesis of CsPbBr3 perovskite quantum dots using bio‐sourced lecithin and hexane enables single‐batch production over 10 grams. Suppressed Auger recombination and electron‐phonon coupling yields 95% PLQY, enhanced stability, and low ASE thresholds of 230.4 (ns) and 50.1 (fs) µJ cm−2 in neat films. ABSTRACT Halide perovskite quantum
