How to Secure the IoT with Blockchain @ [IoT World 2020]
Gemalto, one of the world's largest digital security companies, found that blockchain use cases for securing IoT devices increased from 9% to 19% over the past 12 months..
IN document it is said that implementation is growing even though there is no regulation in this area. Gemalto surveyed 950 IT professionals and managers around the world. 23% of respondents named blockchain as an ideal solution for protecting IoT, and 91% of companies that do not yet use technology in their activities are inclined to do this in the future.
According to researchers, 52% of enterprises are unable to determine if the security of the Internet of Things (IoT) is compromised, even as costs and focus on protecting digital devices rise. Gemalto predicts that the IoT network will exceed 20 billion nodes by 2023, therefore recommends companies not tighten with improving their threat detection systems.
Analysts also note that despite the growth in blockchain adoption, adoption rates are low as businesses continue to rely on other ways to protect. In 71% of cases, this is data encryption, 66% use passwords for this, 38% implement two-factor identification systems.
Jason Hart, CTO of Gemalto's data protection, says businesses clearly feel the need to protect the growing amount of information they accumulate. However, despite investments in technologies security, such as blockchain, they need additional guarantees from regulators. Therefore, business must put pressure on the government, because in the end it is he who will suffer the most from hacks..
Earlier we reported that Russian business will be helped to experiment with high technologies..
Artificial Photosynthesis System as efficient as plants and can reduce CO2 levels #DigInfo
A team of chemists has developed a technology for the production of liquefied fuel from water, carbon dioxide and visible light through artificial photosynthesis.
Plants use solar energy to stimulate chemical reactions between H2O and CO2 in order to synthesize glucose. In a new study, scientists described an artificial process that uses the same raw materials as plants to convert water and carbon dioxide into more complex hydrocarbon molecules like propane..
The role of chlorophyll in the laboratory was played by metal catalysts with electron-enriched gold nanoparticles that absorbed green light and transported the elementary particles needed for the chemical reaction between water and carbon dioxide. Gold interacts well with carbon dioxide and absorbs energy without being destroyed like other metals.
Scientists from the University of Illinois say that liquefied fuel is safer than gaseous fuel, it is cheaper and easier to transport, and its molecules contain more bonds, that is, the energy is packed more densely in them. In their opinion, it is better not to burn the hydrocarbons obtained in this way, but to convert them into fuel cells for the production of electricity..
Despite the potential of green energy technology, researchers recognize that natural photosynthesis in plants is still far more efficient than the artificial process invented. Therefore, they will continue to improve the catalyst to make the method economically feasible..
Recently, an international team of researchers developed method for efficiently converting carbon dioxide into coal at room temperature.

US military command has made synthetic biology research a priority to develop new methods of camouflaging and protecting soldiers.
According to Dimitar Stratis-Kullum, head of the synthetic biology combat capabilities research unit, the army has begun to actively engage regional partners to accelerate the program. «Living materials». Although its budget has not been disclosed, it provides for the development of new technological solutions that will help the American military get out of the battle unharmed..
As an example, the command cites the concept of improved camouflage, which will allow the soldier to blend in with the natural environment. To do this, they plan to use a material that masks the human thermal signature, making it invisible to the lenses of thermal imagers. In parallel, scientists are studying methods of hiding and other traces that betray the presence.
Another potential direction is called the creation of camouflages that repel insects without any toxic impregnations. It is planned that they will contain special biological organisms, bred in the laboratory, which can survive in the wild and in military conditions..
Another example by Dimitar Stratis-Kullum was the forecasting of the future of synthetic biotechnology in the hands of potential adversaries. According to him, the United States fears that Russia and China will begin to use genetically modified soldiers, so the Americans also «have to» study similar technologies in order to predict the impact on the military sphere and prepare.
Recently American military have already begun to equip with tiny drones for espionage.
Hyperloop Transportation Technologies (HTT) announced the completion of a full-scale vacuum train test section in Toulouse.
The track, 320 meters long, will be completely ready in a few weeks, after the installation of the vacuum pump systems is completed. The first tests of the Quintero One passenger capsule should begin in April of this year, and a fully finished commercial line is planned to be launched in about three years.
Hyperloop is one of the few companies working on the implementation a high-speed transport system of the future, which provides for the movement of containers levitating on magnets along the foreline demand at a speed of up to 1250 km / h. However, unlike competitor Virgin Hyperloop One, HTT has not yet conducted test runs and only has a feasibility study available..
According to company representatives, Toulouse will be a testing ground for future commercial projects in Abu Dhabi and China.
We previously reported that in India are working on creating the world’s fastest transport system cargo transportation based on vacuum train technology.
A team of researchers created a durable ultra-thin film made from natural wood, which was then used as a diaphragm for an audio speaker.
Thin films made from plastic, metal, ceramic and carbon are widely used in applications ranging from food packaging and water purification to electronics and solar cells. However, membranes, used in acoustic systems must not only be thin, but also have high mechanical strength in order to provide the necessary sensitivity and vibration amplitude.
Films made of metal, ceramic and carbon are very resilient, but difficult and expensive to manufacture, while plastic films are less efficient and pollute the environment. Therefore, a team of materials scientists and engineers at the University of Maryland at College Park decided to use natural cellulose-based materials as a base..
To create ultra-thin films less than 8.5 micrometers thick, they partially removed lignin (delignification) and hemicellulose from longitudinally cut balsa wood to preserve the canal structure. Further, to increase the density of the obtained porous material, it was subjected to hot pressing, which also reduced its thickness by 97%. Cellulosic nanofibers in ultra-thin film remained highly oriented, but more densely laminated compared to natural wood.
Mechanical tests have shown that the material has a tensile strength of up to 342 MPa and a Young’s modulus of 43.65 GPa. This is 20 and 35 times better than natural wood, respectively.
These characteristics of the film allowed the team to bend and fold it without any problems, as well as use it as an acoustic transducer for assembling a miniature speaker with a wide bandwidth, high sensitivity and high sound pressure levels. The prototype contained a wooden diaphragm and a board with a miniature speaker made of copper coil and permanent magnet.
In the future, the group plans to improve the design of the membrane and develop technology for industrial use in the production of microphones, hearing aids and acoustic sensors..
Bonds on blockchain, World banks issues millions worth bonds in Blockchain
To organize the whole process, four open source smart contracts were used, and the fifth one will pay off in six months.
The total amount of the issue of securities amounted to 750 million rubles, but its main task was not to attract investments, but to scale up the technology for further application after the formation of the legislative base. NSD spokesman said that using smart contracts can reduce technology costs by 10%.
The partners were able to successfully implement a complete DVP settlement model on the blockchain, which ensures the simultaneous movement of bonds and cash. The list of participants is dynamically changed, confidentiality is ensured and access is open for all parties to the transaction (issuer, investor and NSD). The parties can perform the necessary operations online and exchange documents. At the same time, the whole process is decentralized, transparent and protected by cryptography..
MTS told BitCryptoNews that they installed the software on their own and did not experience any particular difficulties, since no significant software modifications were required. Andrey Kamensky, vice president of finance, investments, mergers and acquisitions of MTS, said that the company plans to use blockchain in the future to increase trust between participants and reduce transaction costs.
Recall that the industrial sector received more than 400 million rubles from Igor Chaika.
What are the 7 most dangerous technology trends in 2020?
The latest technologies bring convenience, admiration and a lot of positive emotions into our lives, but we must be vigilant about the possible negative consequences of using innovation. Here is a list of the 7 most dangerous technology trends that have already shown their dark side.
«Propaganda – it is the art of photographing a devil without hooves and horns».
Hans Kasper (1916 – 1990) − German writer and radio show writer.
The number of programs like GROVER is growing steadily in the world media. − an artificial intelligence system capable of writing a fake news article on any topic. Such programs generate more believable articles than copywriters do. The secret is that AI processes large amounts of data and backs up its articles with facts that a person cannot always even guess about..
The most successful in this direction was the non-profit company OpenAI, supported by Elon Musk. The results of OpenAI’s performance are so good that the organization initially decided not to publish the research results publicly to prevent dangerous misuse of the technology. The main danger of believable fake news is that its quality can deceive even critically-minded people who are not brainwashed by propaganda..
The most high-profile example of the negative use of drones was their recent attack on oil platforms in Saudi Arabia, which caused hundreds of billions of dollars in damage. As a result of the attack, the world’s oil reserves were depleted by about 5%, but the convenience of using drones for military operations suggests that such situations will continue to occur..
A swarm of drones can organize to achieve a goal by interacting with each other, creating a new type of ultra-dangerous weapon. At the moment, the technology is still at the experimental stage, but the reality of the swarm, which can coordinate its behavior to achieve the most difficult military tasks, is approaching reality..
Spying on smart home devices
To devices «smart home» able to respond to inquiries and be as helpful as possible, they should be equipped with microphones to listen to voice commands. When a person installs a smart speaker in his room, he also signs that now a scrupulous little spy lives in his house, who does not miss a single word..
All smart devices collect information about habits and preferences, residence and travel routes, arrival and departure times. This information makes life more convenient, but there is also the possibility of data abuse. Thieves and crooks are actively working on tools that will allow them to take over all the information they collect. In the event of a successful hacking of personal data from cloud servers Amazon, Google, Yandex or any other artificial intelligence platform, the attackers will receive all the information they need to blackmail or steal real things from home..
One of the loudest scandals in this direction was the wiretapping by Amazon employees of the recordings of their customers’ conversations with the Amazon Echo smart speaker this spring. Obviously, Amazon employees should not use the information received for personal gain, but no one can guarantee this..
Face recognition thanks to video cameras
Smartphone maker Huawei was accused last year of using facial recognition technologies for surveillance and racial profiling, and handing over access keys to foreign networks to Chinese intelligence.
Millions of cameras on smartphones and laptops are used to track and recognize people not only in the PRC – this practice has been seen in almost every country in the world. The only difference is that somewhere it was possible to prove it (the Snowden case in the USA), and somewhere – not.
Artificial intelligence is capable of generating phrases with the voice of any person. For this, just one piece of audio recording with his voice is enough. Similarly, AI can create a video of anyone that looks natural and believable. The negative consequences of such videos and audio recordings are widespread, from hacking bank accounts to blackmail and political scandals..
Deepfake uses face mapping, machine learning, and artificial intelligence to create behaviors. Different forms of a person’s face act as the initial data for generating a fake, which are easier to obtain from a large array of records. Previously, this kind of open source data was only reserved for celebrities, but social media has changed that. Now ordinary people download gigabytes of amateur videos with them, providing the masters from Deepfake with all the necessary sources for processing.
Most successful in identifying fake videos copes with a program created at the University of Berkeley.
Viruses and phishing combined with AI
Artificial intelligence greatly simplifies the work of phishing networks, which need an effective tool to automate and scale the volume of work. AI helps attackers better find «weak» email addresses and accounts on social networks, more accurately compose the texts of viral fishing tackle letters, bypass anti-virus software more efficiently and, most importantly, collect money in an automated mode without the risk of being tracked by law enforcement agencies. In recent years, withdrawals of funds have become much more often carried out using cryptocurrencies..
Microelectromechanical systems (MEMS) are microscopic in size down to grit. The smallest piece of smart dust is called a moto. Mot – This is a sensor that has its own computing unit, sensors, power supply and data transmission systems. Motes can combine with other specks of dust to form what is called smart dust. Such systems are already being used on an industrial scale by cybercriminals when it is necessary to hide surveillance as much as possible..
How Plastic Waste Is Converted Into Fuel At A New Plant In Indiana
Researchers have developed a technology for converting barley leftovers from breweries into carbon fuel.
Breweries dump huge amounts of unused grain every year, but chemists at Queens University in Belfast have found a cost-effective solution to convert this waste into useful products..
The method developed by the team consists of just a few steps. First, the grain is dried, after which it is subjected to a two-stage chemical and thermal treatment with using phosphoric acid, and then washed with potassium hydroxide. After this remains activated carbon and valuable carbon nanotubes.
The final product can be formed into pellets and used as fuel for heating houses, producing water filters or charcoal for barbecues..
Since the chemical solutions used are readily available and cheap, such processing is cost effective. In addition to the high rates of profitability of synthesis, an additional benefit lies in the parallel disposal of production waste and resource savings.
This direction even an oil and gas company got interested BP, which plans to build new venture in Brazil and annually produce 2 billion liters of biofuel there.

24. Electrical Double Layer, Size Effects in Phase Change
Researchers have created and tested new layered designs for wireless charging devices that double their power density and reduce weight compared to existing technologies..
Modern wireless charging systems for electric vehicles consist of two charging coils, one attached under the vehicle and the other located at ground level. When they are aligned, the transmitted power charges the battery.
A team of scientists from Oak Ridge National Laboratory presented a design of a three-phase system with rotating magnetic fields between the layers of coils that works much more efficiently than existing options.
According to the developers, the laminated coil structure transfers energy more evenly, which allows doubling the power density. During the tests, the three-phase system successfully transferred 50 kW of power with an efficiency of 95%. As the system improves further, the efficiency will increase even more..
This study brings the team closer to building a device to charge an electric vehicle in 20 minutes..
In addition to electric vehicles, the technology is becoming more and more popular for charging batteries for gadgets and recently created a wireless charger that can be shaped into any shape.
This Woman Drank 21 Liters of Water in 24 Hours. This is What Happened to Her Brain…
Scientists have developed an inexpensive water purification system in which carbon nitride, when exposed to sunlight, kills 99.9999% of bacteria, including E. coli. Cleaning 10 liters takes about half an hour.
In the presented system, researchers from Yangzhou University used two-dimensional sheets of graphite-like carbon nitride as an internal photocatalyst. Direct sunlight light material generates electrons, which interact with oxygen in water to create compounds that destroy bacteria.
Although there are now other cleaning systems based on similar chemical processes, but they use photocatalysts, which during operation leave harmful substances as a by-product. However, they also take much longer to disinfect..
According to scientists, their system is ten times more efficient than other alternatives with non-metallic photocatalysts. The team is currently working on placing the invention in portable containers so that they can be used in regions with a shortage of drinking water around the world..
Recall that American engineers have also developed a new technology for the production of filtration membranes from bacterial nanocellulose and graphene, which are able to effectively purify water and have unique antibacterial properties
The world’s first 3D-printed community is officially under construction
In a rural area on the outskirts of a city in southern Mexico, construction has begun on a new neighborhood, all of which will be printed on a huge 3D printer.
Each finished home with a total area of 50 m2 has two bedrooms, a living room, a kitchen, a bathroom and has good resistance to the seismic activity typical of this region of the country. It takes 12 hours to erect the body of one such building using a 10-meter 3D printer..
The roofs, windows and interiors of the first few houses were completed last week, and future families have already visited them..
New neighborhood in south Tabasco will consist of 50 homes to be donated to local residents as part of the Affordable Housing Program for Families in Extreme Poverty.
Although all buildings will be of the same type, but using the application, the team can make small adjustments to the project on the spot..
The project is being carried out by the non-profit organization New Story, together with the construction company Icon, which developed the applied 3D printing technology. They partnered with the state government, which provided land and infrastructure. Local builders were hired for the final finishing.
3D printing technologies increase speed and production efficiency, therefore Navy US plans to create 3D printed submarines.
Scientists Are Making Air Out of Moondust for Lunar Settlements
Researchers at the European Space Agency are developing a system that can produce oxygen from lunar dust (regolith). Technology will help future settlers extract air and industrial materials.
Analysis of lunar dust samples delivered to Earth during missions «Apollo», showed that it contains 40-45% oxygen. However, it is not so easy to extract it, since the gas in the regolith is in the form of oxides as part of various minerals and glasses. To address this issue, a team from ESA is currently testing a prototype of a miniature lunar residual soil recycling plant..
Extraction of oxygen in it is carried out using molten salt electrolysis. For this, the regolith is placed in a metal basket. with molten calcium chloride salt heated to 950 °C, which acts as an electrolyte. Under such conditions, the lunar dust remains solid, but when an electric current is passed through it, the oxides are split, and pure oxygen begins to migrate through liquid salt accumulated at the anode.
A by-product of this process is various metal alloys that are suitable for further use. Therefore, the team is also exploring ways to recycle and use these metals in lunar environments, such as 3D printing..
So far, researchers transform only an artificially created regolith, but it is hoped that the technology will also work effectively with real material. The final version of the system, which can function in low temperature and gravity, like on the moon, is planned to be developed by the mid-2020s..
Although humanity will not soon be able to transfer industrial production to the satellite, but such devices will help the first explorers and colonists to obtain oxygen for breathing and fuel, as well as metals for the repair of equipment. ESA also plans to use regolith as an affordable building material and store of value solar energy.
Future is Made in Finland, Episode 4: First in 6G (full recording)
Scientists have developed ultra-fast electro-optical modulators that convert terahertz data signals into optical signals for direct connection of the receiver antenna to fiberglass. The new approach will significantly speed up the transfer of information in 6G cellular networks.
Although 5G cellular technology is still being tested at the moment, researchers are already actively working on systems for next-generation wireless data transmission. To launch a new format, it is necessary to solve many problems, including the effective exchange of large amounts of information.
Since the receiver antennas must be connected to fiber optic networks, a reliable, portable data stream converter with virtually unlimited bandwidth is required..
Researchers at the Karlsruhe Institute of Technology have developed a promising approach to converting the data stream between terahertz and optical domains. To do this, the group used an ultra-wideband silicon-plasmon modulator with a bandwidth of more than 0.36 THz.. In their experiment, the scientists chose a carrier frequency of 0.2885 THz and reached a transmission rate of 50 Gbps..
The presented concept can significantly reduce the technical complexity of future base radio stations and will be able to provide wireless connection at a speed of several hundred gigabytes per second..
Recall that earlier scientists also reported creation of a prototype of ultrafast laser Wi-Fi.

Bionic eye invented that mimics the functions of the present and is charged by light
Researchers have created a spherical vision sensor that mimics the structure of the human eye and can use sunlight as an energy source.
The development of a team of scientists fromthe Hong Kong University of Science and Technology consists of a focusing lens and an analog of the retina, which is a hemispherical membrane of porous alumina with many embedded nanowires.
These wires are light sensitive and made from perovskite, which is commonly used in solar panels. They perform the same function as the nerve cells in the human eye, transmitting electrical signals when light hits them..
The diameter of the device is 2 cm and it even has an analog of the vitreous body, the role of which is played by an ionic liquid between the lens and the membrane. Indium is additionally used to improve the electrical contact, and to align the matrix socket wire uses silicone polymer.
In addition to the fact that the structure of the sensor is close to the structure living eye, its sensitivity even surpasses the human organ of vision, since it is practically the same for the entire spectrum of visible light. Nanowires are denser than cellular photoreceptors, and their response time is shorter.
However, the current model of the bionic eye cannot yet serve as an effective replacement organ, because with the width of the photosensitive zone of 2 cm, the resolution is only 100 pixels, which is much lower than the level required for obtaining a distinguishable image.
The diagonal viewing angle is also worse (100 degrees instead of 150) and the sensor still needs an external power supply, but the developers are already upgrading the device to make the nanowires function like small solar cells. This should make it completely self-contained..
Nevertheless, even despite the significant drawbacks and high cost of manufacturing such a bionic eye, it significantly surpasses other existing prostheses and, with proper refinement, can lead to the creation of a full-fledged implant for restoring vision..
In addition to artificial eyes, researchers contact lenses are also improved. We previously reported on the creation of working prototypes contact lenses with integrated augmented reality technology.

Why is the Top Left Corner of iPhone Screen Blurry in iOS 14.3? [Fixed]
Apple has filed a patent application for technology that will automatically hide the contents of the device’s screen from prying eyes.
In our computers and mobile phones, a mass of private information is gradually accumulating, attracting the attention of others, who can accidentally look into the display, passing by or standing behind. At the same time, they can find out not only incriminating facts, but also personal data and correspondence. Apple developers have apparently been watching this issue, as the company is patenting a system that will detect unwanted viewers and blur the contents of the screen..
The display encryption technology will use facial recognition to identify the wearer and track the eyes to know which segment of the screen they are looking at. When an unknown person appears in front of the device or a third-party gaze in the background of the user, the system automatically activates the protective mechanism.
In this mode, only the segment that the owner is currently looking at will be clearly displayed on the screen, and the rest of the area is reversibly blurred, distorted and changes color in such a way that the content cannot be recognized from the outside..
If Apple does implement this technology in practice, then initially it will be applied to smartphones, laptops and tablets, but in the future it can also be integrated into wearable smart devices..
We also previously reported on the development of a system that warns pedestrians. in headphones about approaching cars.
