Counterfeit Money Prevention Possible Through A New Magnetic Nanomaterial

Counterfeiting currencies is considered one of the oldest crimes in human history. As people began trading goods through coinage, many people have attempted to use fake, lower-value versions of currencies.

As technology gets more advanced, counterfeit money also gets harder to identify. This counterfeit fraud is harmful to businesses and individuals’ financial health and profitability and should get solutions as fast as possible.

This article will inform you on how to spot counterfeited money using several manual and machine-aided methods. Afterwards, you will also know more about magnetic nanomaterial, a scientific advancement for counterfeit money prevention.

How to Spot Counterfeited Money?

Color-Shifting Ink

Holding a new series of banknotes and tilting it back and forth is usually the first step to check the genuineness of the money. If the numeral in the lower right-hand corner shifts from green to black or from gold to green, it is authentic.

Bill Watermark

It should only be visible when you hold it up to the light and be on the right side. If there is no watermark or it is visible without being held up to the light, there is a high chance that the bill you have is a counterfeit.

If it’s a face as a watermark, it should exactly match the face on the note. Counterfeits undergo bleaching of lower bills and are printed once again with higher values, which would result in a face that will not match the watermark.

Blurry Borders, Printing, or Text

Original bills use printing plates that are die-cut which create impressively fine lines that have very detailed features. Counterfeited money usually does not have the same level of detail and does not contain microprinting or finely printed text. The banknote is probably counterfeit if, even under a magnifying glass, the microprinting is unreadable.

Raised Printing

Run your fingernail carefully down the note to detect raised printing features. Some nail vibrations from the ridges of the raised printing should manifest, and if you don’t feel the texture, you should be more cautious.

Security Thread with Microprinting

A security thread that is a thin imbedded strip running from top to bottom on the face of a banknote comes with microprinting. If you don’t find one, it’s best to turn it over to authorities.

Ultraviolet Glow

Ultraviolet light is helpful because of its clear-cut way of telling the notes’ authenticity. The security thread on original bills glows under ultraviolet light.

Red and Blue Threads

These are minuscule red and blue threads woven into the fabric of the bill. If it is obvious on the printed notes’ surface level, it is most likely that the bill is a counterfeit.

Serial Numbers

The letter that starts a banknotes’ serial number always corresponds to a specific year. A counterfeited note has letters that do not match the year printed on the bill.

Existing Counterfeit Money Prevention Methods

Spotting counterfeited money using the naked eye is a rather outdated prevention method. In this age of technology and innovation, machines made solely for this purpose exist, such as the following:

Ultraviolet

Banknotes incorporate invisible UV marks that are only visible under ultraviolet light. To be specific, it can’t just be any ultraviolet light, for it needs to be at a wavelength of 365 nanometres to work.

Magnetic and Metal Thread

Banknotes have ferromagnetic ink printed on them in complex magnetic patterns. Usually, this magnetic thread is interweaved into the notes in specific sizes and locations.

Infrared

Banknotes have inks that are only invisible to the naked eye and only become visible under infrared light. Infrared sensors reflect and absorb light using the special characteristics marked on each denomination.

Size Detection Devices

Each banknote denomination has the same length, width, and thickness, making this another way to check for fake notes using 3D measuring methods.

Serial number and CIS

Authentic banknotes have a unique serial number on each side, which is usually helpful for financial ledgers and reports. Detection machines use an advanced Contact Image Sensor (CIS) sensor to scan and record the serial numbers.

New Innovative Counterfeit Money Prevention Method?

An internationally recognized research team spearheaded by NUST MISIS has discovered and developed a new counterfeit money prevention method using iron-cobalt-nickel nanocomposite with tunable magnetic properties. The nanocomposite will be helpful to protect money and securities from counterfeiting.

What are Magnetic Nanomaterials?

Due to their unique properties, magnetic nanomaterials (MNMs) have attracted significant interest. The nanoparticles fluctuate as a result of thermal energy.

According to Yuri Konyukhov, Deputy Head of the Department of Functional Nanosystems and High-Temperature Materials at NUST MISIS, this innovation uses a simple method that allows the control of the product’s properties at each stage of its production.

Benefits of Magnetic Nanomaterial in Counterfeit Money Prevention

Magnetic nanomaterials possess a high value of coercivity, making them applicable to protecting money and securities from counterfeiting.

Konyukhov further stated that the scientific community has recently focused its efforts more than ever to protect humans and electronic devices from possible electromagnetic radiation.

This development of using thin, flexible, and relatively transparent metal-polymer composites is a promising research direction. The new magnetic nanocomposite with controlled magnetic properties as the magnetic filler could lead to a scientific breakthrough.

The Future Usage of AI to Diagnose Skin Conditions

Skin is indeed our largest organ of the body, and most importantly, also the most visible organ in the body. Hence, this is the reason why a plethora of people is very particular about their skin. Therefore, a dermatologist plays a huge role in our lives, as they are the ones who help us treat all our skin problems, and with that, we can get flawless skin which everyone dreams about. However, there is a need for advanced tools to diagnose the different skin conditions, as manually, the diagnosis is not that effective.

Each year as per Google, there are almost 10 billion searches about how to treat different skin issues. Also, 2 billion + people across the world each year suffer from skin-related issues. People have been finding out ways to deal with their skin problems and get an accurate diagnosis. The Internet is indeed one of the places to search for solutions; the problem is that the Internet also gives the wrong reassurance in terms of skin issues.

Dermatologists are undoubtedly doing their best when it comes to resolving skin issues, but with the help of technology, it can just become 10x times easier to diagnose the skin conditions and act upon them accordingly.

Artificial Intelligence – Progressively Used in Dermatology

In the dermatology sector, artificial intelligence has been increasingly applied. As a result, there is a dire need to understand and use the progress of the technology which has been helping and shaping the future of dermatology.

Artificial Intelligence is one the greatest inventions in technology, helping many industries provide robust solutions, which were not possible earlier. Many dermatologists have also been making use of AI to diagnose skin conditions. There is recently a buzz about a tool that makes use of AI to diagnose skin conditions.

Working on the AI-Powered Dermatology Tool

There is an AI-powered dermatology tool, which helps doctors to understand what is the exact skin issue by penetrating deep into the tissue layers to diagnose accurately. The tools help the individuals get closer to some skin issues such as rashes, allergies, etc., just with the help of their phone’s camera.

The all-new AI-powered dermatology tool is known to be a web-based application, which, hopefully, when launched, will make it easier for dermatologists to figure out what exactly is going beneath the skin. The individual on whom the tool will get used will be asked multiple questions to diagnose the problems, such as:

• What is your skin type
• For how long the issue has existed
• Various other symptoms which bring closer to diagnosis

Based on the answers given, the model will be able to analyze information and then draw out inferences from about 288+ issues related to skin problems. The tool gives out the entire list of all the possible matching conditions which can be researched further.

Working on the AI-Powered Dermatology Tool

For every matching information, the dermatologists will get help from the tool to see all the reviewed information and the answers to some of the most commonly asked questions. Also, an important point to note is that this dermatologist tool cannot provide any particular treatment or substitute for any medical conditions. The primary aim of the tool is simple, to give utmost information so that the individual has access to make informed decisions about what needs to be done.

AI-Based Model That Helps in That Helps in Assessing Different Skin Types

With the proper cumulation of AI-based techniques and machine learning, a tool has been made to help assess different skin types in the best way possible.

As per research, it has been claimed that AI is very powerful and can achieve at par accuracy. The tool also claims that non-specialists doctors can also use AI-based tools to improve the overall ability to interpret skin problems.

The AI tools have been modelled to account for factors such as age, skin type, sex, etc. A pale skin that does not tan at all to a brown skin that rarely gets burns, everything is accounted for here.

AI to diagnose skin conditions has been on the radar of dermatologists, and for the same, there has been a huge amount, which can properly help in the diagnosis of skin issues.

Web Frameworks For Peak Productivity and Output in 2021

The craze of web programming is still as strong as it has always been. In the meantime, individuals and companies are rushing to maintain a strong presence in the online space. Time is a key factor if you want to survive in intense competition. Furthermore, web technology is constantly changing and evolving based on new challenges in security, speed, and user experience. This is where the web frameworks come in.

Web frameworks are a type of software framework that eases the process of building web applications. Since most of the tasks we perform in web development, like creating databases and templates, are repetitive, web frameworks contain a huge library of pre-designed components that we can manipulate according to our needs. Likewise, web frameworks come in two different types. Client-side web frameworks focus mainly on user interfaces, whereas server-side web frameworks take care of the internal website functions.

Our Top Picks

To make the lives of our readers easier, we came up with the top picks for the best web frameworks to use in 2021.

Laravel

Laravel is a PHP framework that has massively grown in popularity and usage in recent years. The main objective of this web framework is to reduce the complications in the development process. This means developers can focus on the business side of their applications while the common tasks like routing, authentication, caching, and session management are taken care of. Therefore, it has been one of the favourite web frameworks with more than sixty thousand stars in Github, the most popular software hosting and version control site.

The following is a list of some of the most exciting features of Laravel.

• The template engine allows developers to quickly create beautiful layouts, both simple and complex.
• Its beautiful ORM (Object Relational Mapping) model makes it easy to interact with databases. Since you can write database queries using PHP syntax, you don’t need to be a SQL master at getting started.
• It offers a high degree of security to your web application. Features like prepared SQL statements prevent SQL injection attacks while hashed passwords prevent illegal extract of information from the database.
• Unit testing is one of the best in all web frameworks. It supports multiple unit testing, which means all the changes will undergo strict checks before the website goes live.

React.js

React.js is one of the most widely used web frameworks in the world. Since its launch in 2013, it has quickly become a favourite for front-end developers. Today, it is maintained by Facebook along with thousands of other developers. Similarly, more than thirty thousand websites use this web framework, including top companies such as Apple, Netflix, and Uber.

So what makes it one of the top web frameworks for developers? The following is a list of its features and advantages that enables it to stand out from the crowd.

• With React, creating interactive UIs is quick and easy. It can effortlessly render and update the right UI components when the data changes. This means your code looks beautiful, and debugging is easy.
• In React, the data flows from the parent to the child structures in a top to bottom fashion. This means changes in low-level structures cannot affect high-level structures. This leads to a more stable code.
• Since React runs on the server and returns virtual DOM to the browser, search engines can easily read such web pages. This means you have a better performance on Search Engine Optimization (SEO). On the other hand, if your webpage is javascript-heavy, it will degrade the SEO performance.

Django

Django is a Python-based web framework that supports the rapid development of Web applications with little code. Since Python is easy to learn, it makes Django one of the most beginner-friendly web frameworks. Likewise, its documentation and tutorials are well developed so that developers spend less time wandering around.

Why should you use Django then? Here are the features and advantages of Django that will make you want to get started now:

• Django is built on Python, and Python allows you to do more in less code. Furthermore, it is free and open-source, so that you need not care about money.
• Django takes care of much of the web development tasks such as authentication, content administration, site maps, and RSS feeds. This means that you can focus more on the business side of things.
• It derives the versatility of Python. You can use Django to build multiple types of software, ranging from social networks to scientific computing platforms.
• With robust authentication and security features, Django eliminates common security loopholes like SQL injection, cross-site scripting, and clickjacking.
• When the traffic scales up, so will your software capabilities. This scalability of Django makes it one of the top favourites for the busiest sites in the world.

Ruby on Rails

Ruby on Rails is one of the most popular open-source web frameworks used by millions around the world. In addition to removing all the unnecessary hassles in web development, it makes learning easy and fun. Likewise, it has a well-nurtured community of developers who can support you at any time.

5 Things that You Must Know Prior to Developing a Food App

The food delivery industry has grown significantly during the last five years, especially in the pandemic period. This is the most favourable time for start-ups thinking of developing a food app. Today, people favour eating their favourite food at home rather than go out and dine at fancy restaurants. Food apps like Swiggy, Zomato, or UberEats have made ordering meals so easy, by clicking with your mouse or by a couple of taps with your fingers.

If you want people to accept and love your app, you need to remember that it must be user-friendly and have looks and features that will set it apart from others. This field is highly competitive, and you should spare no effort to make your app extraordinary. This article will showcase the essential factors you must consider while making your food app.

Simple, Uncluttered Interface

Customers will only use an app that makes ordering food easy and provides them with every information they need, such as menu items or available offers. Your app needs to load very fast and must have a clean interface with simple features. Customers with lesser technical skills will not think twice about uninstalling your app if it is too complex. So, if you want people to love your app, provide them with an attractive and uncomplicated interface. Design in such a way that makes it easy for them to search for restaurants or know about discounts or offers. They should be able to use any feature easily without encountering unwanted issues.

Add Features for Online Payment

Mobile online payment is important, with the popular payment platforms having millions and even billions of users. People today keep less cash at their homes and prefer making digital payments. Online payments are an excellent option for customers who order food on behalf of others but will not be present at the time of delivery. Another problem that is often encountered is that the delivery person sometimes does not have the change in cash to return to the customer. With an online payment feature, you can prevent all such issues and make transactions smoother.

Ensure that the Customers’ Data is Secure

With online scams on the rise, most customers are apprehensive about making online payments. There have been many instances in recent times of malicious hackers stealing the customers’ valuable bank details. Therefore it is crucial to provide a secure payment gateway to customers to ensure they feel safe while making such transactions. Take their consent whenever you require their personal information. By taking all these steps, you win your customers’ trust in your app.

Add a Feature to Track the Delivery Status

Even though ordering food and eating within their home’s comfort is very convenient, no customer would like to taste or reheat cold food. They would prefer hot food that is delivered as quickly as possible. That is why most popular food apps are adding a special feature that provides live tracking of their delivery personnel. This also benefits the restaurant owners as they can find out if customers are getting timely deliveries or not. They can then take active steps to improve their service.

Know All About Your Customers and Restaurants

To ensure your business’s success, you must know everything about the customers to whom you are catering. Research thoroughly and find out the likes, dislikes, and other details about your customers. You should base your app’s design on the data you collect about your potential audience. Everything about the app, such as its design, features, interface, and functionalities, should be designed keeping your customers in mind.

You also need to prepare a list of restaurants that would deliver food through your app. Get every possible detail about the restaurants like their address, contact number, their food, the areas where they deliver, and so on.

Besides the above, you can also add a feature that allows customers to give feedback about the delivery person. This will help you monitor whether your delivery personnel are making on-time deliveries and if their conduct is appropriate.

If you consider all these factors before developing a food app, you will gain a competitive edge over other established apps. If you want to enlist a mobile app development firm to help design your app, make sure that you hire a firm that can convert your ideas into reality and help you gain a foothold in this rapidly evolving industry.

Smart Cities Will Support The Livable Future

The notion of smart cities is not very new, and we have heard of it for a long period of time. Most of the time, we hear it from high-profile political leaders in their rallies and state and local level leaders. However, as our society becomes closely connected to technology, the future may not be very far. Some of the most advanced cities in the world, like Singapore, Dubai, Oslo, New York, London, Copenhagen, Amsterdam, etc., have already started to adopt the concepts and practices of smart cities.

So, what is a smart city, and what makes a city smart? A smart city is a city that uses modern Information and Communication Technologies (ICT) to improve its daily operations and the lifestyle of people. These technologies are typically referred to as the Internet of Things (IoT), indicating close connectivity between millions of people and devices required to ensure day-to-day operations. This has led to improvements in infrastructure, service delivery, operational efficiency, and quality of life.

ICT As the Key Driver of Smart Cities

The injection of ICT in multiple applications that impact people’s daily lives will be the foundation of the smart cities of the future. The following is a description of major technologies that will find most applications as we move towards a smart future:

Internet of Things (IoT)

The Internet of Things (IoT) is the primary technology that shapes the design and building of smart cities. IoT refers to a vast network of millions, if not billions, of connected devices that exchange data at regular intervals. For example, there may be a smart grid that can send electrical power to homes and industries, depending on their needs.

Similarly, the transportation systems can be connected to the cloud providing information about the status of vehicles in the city. Furthermore, environmental sensors can keep track of pollution, emission, and waste levels providing valuable information to planners and policymakers.

Artificial Intelligence (AI)

Artificial Intelligence is one of the most exciting fields inside Computer Science which has shown tremendous potential for the future. At present, they are at the heart of technologies such as self-driving cars and industrial robots. In smart cities, AI systems can be used in traffic management, security and surveillance, sustainable development, and governance. The major objective of employing these systems is to make sense of the enormous volume of data produced by the IoT infrastructure.

Big Data and Cloud

Big data and cloud are the major technologies required to ensure the success and survival of IoT systems. Without the capacity to store, process, and interpret billions and billions of data points being generated every day, the spirit of smart cities cannot exist. Big data technologies based on distributed or cloud computing systems will handle this monstrous volume of data. Cloud-based technologies are already a major requirement for most industries today.

ICT For a More Livable Future

ICT has the capacity to cause a drastic improvement in the lives of people compared to what it is today. Some of the reasons why ICT-based smart cities will be better to live in are given below.

Improved and More Accessible Infrastructure

The major infrastructures of development like education, health, and transportation have already seen improvements with the integration of ICT. Online learning has become a great relief for educators and students, and its importance has been magnified due to the recent coronavirus crisis. Similarly, ICT has a great potential in healthcare delivery and service.

Remote health monitoring can help doctors monitor distant patients with the help of connected medical devices and electronic medical records. In the wake of the pandemic, as hospitals got crowded with virus-infected patients, remote monitoring immediately became essential. Furthermore, smart ICT solutions have helped cities deal with traffic congestion and optimize transportation services to commuters.

Improved Sustainability

With the integration of ICT, it will be possible to measure waste and pollution from homes and industries. Likewise, smart power delivery systems can assist largely in energy savings by providing only according to needs. Intelligent waste collection, classification, and treatment systems will improve the practice of reusing and recycling.

Greater Security

One of the major requirements for smart cities is to improve the sense of safety and security among people. In the last decade, we saw an increasing threat of both domestic and international terrorism in all the continents of the world. ICT will provide law enforcement and intelligence agencies with vital information that can be used to tackle possible threats early on. For example, intelligent cameras equipped with facial recognition and object detection systems can report suspicious activities in crowded and public places.

Major Challenges

Although the concept of smart cities looks bright and vibrant, it is not free of challenges. The major threats that must be addressed for the implementation of smart cities are as follows:

Data Security

In smart cities, the greatest challenge is to ensure the security of data being generated daily. Electronic medical records, financial records, and government records are critical data in smart cities. Illegal hackers have continuously improved their techniques and practices to breach some of the safest spaces in the world. If we want to build cities that operate and thrive on data, security must be the number one priority.

Increased Surveillance

In smart cities, there is a need to advance and expand surveillance systems to ensure a greater level of security. However, some may argue that an increased amount of surveillance is a breach of the right to privacy. Therefore, planners and policymakers must find a compromise between safety and privacy to gain wider public support.
