We face complexity, ambiguity, and uncertainty about the future consequences of cryptocurrency use. There are doubts about the positive and negative impacts of the use of cryptocurrencies in the financial systems. In order to address better and deeper the contradictions and the consequences of the use of cryptocurrencies and also informing the key stakeholders about known and unknown emerging issues in new payment systems, we apply two helpful futures studies tools known as the “Future Wheel”, to identify the key factors, and “System Dynamics Conceptual Mapping”, to understand the relationships among such factors. Two key scenarios will be addressed. In on them, systemic feedback loops might be identified such as a) terrorism, the Achilles’ heel of the cryptocurrencies, b) hackers, the barrier against development, and c) information technology security professionals, a gap in the future job market. Also, in the other scenario, systemic feedback loops might be identified such as a) acceleration of technological entrepreneurship enabled by new payment systems, b) decentralization of financial ecosystem with some friction against it, c) blockchain and shift of banking business model, d) easy international payments triggering structural reforms, and e) the decline of the US and the end of dollar dominance in the global economy. In addition to the feedback loops, we can also identify chained links of consequences that impact productivity and economic growth on the one hand, and shift of energy sources and consumption on the other hand.

Equity Group kick starts a 35 million trees planting campaign

Posted by in categories: employment, food, security, sustainability

You can protest about the Environment all you want, while some of us actually plant trees to heal it. Kenya is one country that has been instrumental in planting trees. Wangari Maathai had a coffin made of hyacinth, showing how real she was even in death. Ethiopia recently set a record planting trees. Some people talk, while others do. One Kenyan woman’s organization planted over 51 million trees, and still counting. #BeTheDifference


Equity Group has announced plans to implement an ambitious project to plant 35 million trees across the country within a year.

In an effort to conserve the environment, Equity has partnered with Kenya Forest Service (KFS) to promote Farm Forestry Initiatives.

Without encryption we will lose all privacy. This is our new battleground

Posted by in categories: computing, encryption, government, security, surveillance

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.

• Edward Snowden is a US surveillance whistleblower.

3D integrated metasurfaces stacking up for impressive holography

Posted by in categories: computing, encryption, engineering, holograms, nanotechnology, physics, security, transportation

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 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.

These clothes use outlandish designs to trick facial recognition software into thinking you’re not a human

Posted by in categories: government, mobile phones, robotics/AI, security

Smile! You’re on camera — or you were at some point in the past few years — and now your face is public domain.

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.

France Set to Roll Out Nationwide Facial Recognition ID Program

Posted by in categories: finance, government, robotics/AI, security

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.

Researchers’ new method enables identifying a person through walls from candidate video footage, using only WiFi

Posted by in categories: habitats, internet, law enforcement, security, surveillance

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 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.

Researchers invent low-cost alternative to Bitcoin

Posted by in categories: bitcoin, computing, cryptocurrencies, law, security

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.”
