Adaptive Transformation for Robust Privacy Protection in Video Surveillance

Advances in Multimedia, 2012
Privacy is a big concern in current video surveillance systems. Due to privacy issues, many strategic places remain unmonitored leading to security threats.

Light‐Controlled Localized Delamination and Blistering of Azobenzene‐Containing Polymer Thin Films in an Aqueous Environment

Advanced Materials Interfaces, EarlyView.
When exposed to light of a defined wavelength, the photoisomerization of azobenzene chromophores leads to polymer reorientation, generating stresses that result in solvent‐facilitated localized delamination of the film from the substrate. Additionally, blisters that form spontaneously when exposed to an aqueous environment can be manipulated via ...

Two‐Step Thermal Upcycling of Flexible Printed Circuit Board Waste Into Metallic Copper Nanoparticles: Synthesis and Characterization

Advanced Materials Technologies, EarlyView.
A two‐step thermal upcycling process converts flexible printed circuit board waste into high‐purity copper nanoparticles using polymer degradation and arc discharge. The synthesized nanoparticles exhibit controlled morphology and high metal purity.

Region‐Specific Profiling of the Gut Microbiome and Metabolite Landscape in Response to Dietary Intervention Using Electronics‐Free Ingestible Smart Sampling Capsules

Advanced Materials Technologies, EarlyView.
Region‐specific profiling of the gut microbiome is achieved non‐invasively using electronics‐free ingestible sampling capsules that activate at defined intestinal sites through stimuli‐responsive coatings. Deployed in a porcine dietary intervention model, the capsules resolve spatially distinct, fiber‐driven shifts in microbial composition and short ...

The method for approximate continuous Skyline query based on privacy protection in road network

Journal of Big Data
Existing road network continuous Skyline queries often neglect user location privacy and data privacy protection. This paper proposes a method for Approximate Continuous Skyline Query with Privacy Protection in road network (ACPP) environments to address

Thermoresponsive Self‐Healing Carbon Nanotube‐Reinforced Dual‐Network Hydrogels for Wearable Sensors and Information Concealment

Advanced Materials Technologies, EarlyView.
A CNT‐reinforced dual‐network hydrogel combines ionic liquid‐mediated thermoresponsiveness, dynamic covalent crosslinking, and conductive nanostructures within a single adaptive material. The hydrogel exhibits ultrafast gelation, autonomous self‐healing, >1000% stretchability, reversible optical switching, and stable electromechanical sensing, enabling

Understanding the Impact of Institutional Privacy Violations in Algorithmic Social Media on Information Disclosure and Privacy Fatigue: Insights From the Protection Motivation Theory

IEEE Access
Instead of increasing the motivation of some users to protect their privacy, frequent institutional privacy violations have enhanced their privacy fatigue, which may cause them to give up privacy protection and continue to disclose their information even

Coherent Absorption Reveals Colors Hidden in a Grey Fabry–Pérot Cavity

Advanced Optical Materials, EarlyView.
A dielectric thin film shows colors depending on its thickness; this effect can be used to encode information normally accessible through single‐beam spectroscopy. We developed a method to conceal this kind of information, based on coating the dielectric with a matched conductor, that suppresses the color‐bearing thin‐film resonances.

Transparent government, not transparent citizens: a report on privacy and transparency for the Cabinet Office

, 2011
1. Privacy is extremely important to transparency. The political legitimacy of a transparency programme will depend crucially on its ability to retain public confidence.
