And yet, in the midst of the greatest computer security crisis in history, the US government, along with the governments of the UK and Australia, is attempting to undermine the only method that currently exists for reliably protecting the world’s information: encryption. Should they succeed in their quest to undermine encryption, our public infrastructure and private lives will be rendered permanently unsafe.

The US, UK and Australia are taking on Facebook in a bid to undermine the only method that protects our personal information.

Physicists and materials scientists have developed a compact optical device containing vertically stacked metasurfaces that can generate microscopic text and full-color holograms for encrypted data storage and color displays. Yueqiang Hu and a research team in Advanced Design and Manufacturing for Vehicle Body in the College of Mechanical and Vehicle Engineering in China implemented a 3D integrated metasurface device to facilitate miniaturization of the optical device. Using metasurfaces with ultrathin and compact characteristics, the research team designed optical elements by engineering the wavefront of light at the subwavelength scale. The metasurfaces possessed great potential to integrate multiple functions into the miniaturized optoelectronic systems. The work is now published on Light: Science & Applications.

Since existing research on multiplexing in the 2-D plane remains to fully incorporate capabilities of metasurfaces for multi-tasking, in the present work, the team demonstrated a 3D integrated metasurface device. For this, they stacked a hologram metasurface on a monolithic Fabry-Pérot (FP) cavity-based color filter microarray to achieve simultaneous cross-talk, polarization-independent and highly efficient full-color holography and microprint functions. The dual function of the device outlined a new scheme for data recording, security, encryption color displays and information processing applications. The work on 3D integration can be extended to establish flat multi-tasking optical systems that include a variety of functional metasurface layers.

Metasurfaces open a new direction in optoelectronics, allowing researchers to design optical elements by shaping the wavefront of electromagnetic waves relative to size, shape and arrangement of structures at the subwavelength. Physicists have engineered a variety of metasurface-based devices including lenses, polarization converters, holograms and orbital angular momentum generators (OAM). They have demonstrated the performance of metasurface-based devices to even surpass conventional refractive elements to construct compact optical devices with multiple functions. Such devices are, however, withheld by shortcomings due to a reduced efficiency of plasmonic nanostructures, polarization requirements, large crosstalk and complexity of the readout for multiwavelength and broadband optical devices. Research teams can therefore stack 3D metasurface-based devices with different functions in the vertical direction to combine the advantages of each device.

Facial recognition technology is everywhere, and only becoming more pervasive. It’s marketed as a security feature by companies like Apple and Google to prevent strangers from unlocking your iPhone or front door.

It’s also used by government agencies like police departments. More than half of adult Americans’ faces are logged in police databases, according to a study by Georgetown researchers. Facial recognition technology is used by governments across the globe to identify and track dissidents, and has been deployed by police against Hong Kong protesters.

From facial recognition security to unmanned vehicles, Alibaba’s corporate campus is the office of the future. CNBC’s Uptin Saiidi gets a rare look inside the company’s headquarters in Hangzhou, China, where more than 20,000 employees are based.

With the move, France will join states around the world rushing to create “digital identities” to give citizens secure access to everything from their taxes and banks to social security and utility bills. Singapore uses facial recognition and has signed an accord to help the U.K. prepare its own ID system. India uses iris scans.

France is poised to become the first European country to use facial recognition technology to give citizens a secure digital identity — whether they want it or not.

Saying it wants to make the state more efficient, President Emmanuel Macron’s government is pushing through plans to roll out an ID program, dubbed Alicem, in November, earlier than an initial Christmas target. The country’s data regulator says the program breaches the European rule of consent and a privacy group is challenging it in France’s highest administrative court. It took a hacker just over an hour to break into a “secure” government messaging app this year, raising concerns about the state’s security standards.

The World Economic Forum has partnered with the Inter-American Development Bank and the Colombian Inspector General’s Office to explore how distributed ledger technology can improve public transparency and integrity in school meal procurement.

The project, which is taking place this year, is multi-faceted and includes a software implementation with blockchain technology for the selection of school food vendors. It is co-designed with several partners from academia, the IT industry, and the non-profit world, including economists and computer scientists from the blockchain economics and governance consulting firm Prysm Group, the National University of Colombia, U.C. Berkeley, and the blockchain security firm Quantstamp.

Researchers in the lab of UC Santa Barbara professor Yasamin Mostofi have enabled, for the first time, determining whether the person behind a wall is the same individual who appears in given video footage, using only a pair of WiFi transceivers outside.

This novel video-WiFi cross-modal gait-based person identification system, which they refer to as XModal-ID (pronounced Cross-Modal-ID), could have a variety of applications, from surveillance and security to smart homes. For instance, consider a scenario in which law enforcement has a video footage of a robbery. They suspect that the robber is hiding inside a house. Can a pair of WiFi transceivers outside the house determine if the person inside the house is the same as the one in the robbery video? Questions such as this have motivated this new technology.

The cryptocurrency Bitcoin is limited by its astronomical electricity consumption and outsized carbon footprint. A nearly zero-energy alternative sounds too good to be true, but as School of Computer and Communication Sciences (IC) Professor Rachid Guerraoui explains, it all comes down to our understanding of what makes transactions secure.

To explain why the system developed in his Distributed Computing Lab (DCL) represents a paradigm shift in how we think about cryptocurrencies—and about digital trust in general—Professor Rachid Guerraoui uses a legal metaphor: all players in this new system are “innocent until proven guilty.”

Security researcher Axi0mX published the exploit, called “checkm8,” Friday on Github. It affects every Apple device with an A5 through A11 chipset, meaning every iPhone model from 4S to X. Though it isn’t an all-in-one jailbreak on its own, the exploit provides an extensive foundation for researchers to build off of in customizing jailbreaks for every vulnerable model of device that would allow them to totally take over the unit, run software far beyond what Apple normally allows, and program apps to interact and share data in ways that Apple’s protections usually preclude.

Any iPhone device from 2011 to 2017 could soon be jailbroken, thanks to an underlying flaw that there’s no way to patch.
