Now fingerprints are also insecure? The researchers warned


Recreate a person's fingerprints from the sound while swiping a touchscreen: Researchers have discovered how to recreate a person's fingerprints from the sound made while swiping a touchscreen? A research was done by a team of US and China. The research said the new hack could have implications for biometric security systems, which are used in everything from smartphones to door access locks.

The smartphone's microphone is used

Hackers can use the microphone found in smartphones to steal fingerprints by recording the sound of the fingerprint, the researchers said. In this regard, the researchers said in the research paper that the leakage of fingerprints can lead to theft of sensitive information, financial loss and also affect national security.

A person's fingerprint can be created with the help of technology

PrintListener works by reconstructing the pattern of finger papillary lines through acoustic signals. A person's fingerprint can be easily generated using PrintListener. The method was detailed in a research paper titled 'Print Listener: Uncovering the Oneness of Fingerprint Authentication via the Finger Friction Sound' by a team from the US University of Colorado and Tsinghua University, Wuhan University and Huazhong University of Science and Technology.

This way fingerprint cloning can be avoided

Special screen protectors should be used on mobile devices to protect against fingerprint cloning. The best counter-measure to prevent fingerprints from being stolen is to change the way we use smartphones and screens. For example, users try not to swipe their fingers on the phone screen while making audio and video calls on social media platforms.

Moon Mission: Where on the Moon - Where will water be found? Map prepared by NASA

Image
New delhi date. 22 March 2023, Wednesday For the first time, scientists have created a map of water on the moon. In which the possibility of having water on the moon has increased. According to the information, scientists have prepared a map of the presence of water in the moon through NASA's Stratospheric Observatory for Infrared Astronomy. With the help of this map, we have tried to show how the movement of water takes place in the moon. The map of water in the moon that scientists have prepared has focused on the south pole of the moon, i.e. the South Pole. Scientists believe that the creation of this map is a big step in the search for water on the moon. This map is made of the Earth side of the Moon. Experts say that this map is going to be very useful. Scientists presented the map at the 2023 Lunar and Planetary Science Conference. Giving information about the map, the expert said that the mountain can be easily seen in this map and the difference between night and day ...

The facility of posting in threads is coming from Facebook

Image
Taking advantage of Twitter company's name change and other major upheavals last year, Meta Company launched a new social platform ' Threads ' almost like Twitter. When the Threads service launched in July 2023, it was launched along the lines of the already hugely popular Instagram to give it a large user base from the start. Hence, if we have an Instagram account, we can sign-up in the threads from it and the Instagram username and followers are also added to the threads. Due to this the threads got a very fast growth initially. In the first month itself , in fact in the first five days, the number of its users reached the mark of 10 crores. However, then the enthusiasm of the users began to wane. Since Instagram and Threads are connected to each other, users in Threads remained but their actual activity started to decrease. It seems that even the meta company did not live up to the expectations it had from Threads. Hence, the company has started looking for new...

One year into the ONDC system: How far has the e-Cormus initiative come?

Image
The Open Network Core Digital Commerce (ONDC) project was launched in India in April last year. Amazon and Flipkart currently have a duopoly in the e-commerce sector in India and both of these companies are foreign-owned. The ONDC project has been implemented by the Government of India so that various companies and small and large businesses in India can take full advantage of e-commerce and instead of the entire system being in the hands of just one or two companies, it also gets democracy. The way Unified Payment Interface (UPI) has revolutionized online transactions in India. Something similar is likely to happen in the e-commerce sector due to ONDC. After its launch in April last year, the network was seeing 30-40 transactions per day in the month of September , which has now reached 600 transactions per day. Given the prevalence of online commerce in India, this number is still very low. However, the number of merchants connected to the network has increased significantly. Af...

Will it be possible to ride a bike in the air in the next two to three years?

Image
New York, October 30, 2021, Wednesday All obstacles have to be overcome when a bike or car is passing on the road. No matter how much haste the driver can't fly, so far the only option to fly is the plane but now flying cars and bikes are no longer just a fantasy. The days of being able to ride a bike are not far off as there is solid research work going on. An American aviation company is moving in the direction of conducting concrete experiments. A successful test flight of the motorcycle prototype has also been announced. This flying bike will be ready in 3 to 4 years. This requires the development of a special flight control software program. The bike can be successful in balancing in the air in the time to come. According to the information received, the bike will be able to take off and land directly but it will require as much space as a car. The speed of the flight bike will be 30 km per hour while the flight time will be around 15 minutes. You don't even need to ha...

The Carmen line crossed by Bezos is the line of sight between Earth and space

Image
WASHINGTON: The world's richest space tourist, Jeff Bezos, rode in a Blue Origin capsule inside his rocket New Shepherd, and in the meantime, his rocket took him into space and from there his capsule was released from the Blue Origin. Many may have wondered after reading this news that Bezos may have gone into space but what is it that has crossed this Carmen line. This Carmen line is actually the line of demarcation between the earth and space. This line completes the Earth's boundary and begins the space boundary. The Carmen Line is the boundary between Earth and space. It is 100 kilometers above sea level (54 nautical miles, 62 miles, 3,30,000 feet). The line was established in 1960 by the Federation Aeronautics International (FAI). The Federation of Aeronautics International (FAI) is the unit that holds the international record of aeronautics. The Carmen Line is named after Theodore von Carmen (1881-1963). He was a Hungarian and an American physicist. He was active in...

IIT researchers develop real-time underwater marine robot, eases deep-sea surveillance

Image
image : Envato and Twitter Real-time underwater marine robot: Indian Institute of Technology (IIT) Mandi and Palakkad have achieved a tremendous achievement in developing real-time underwater marine robot for underwater surveillance. The function of this robot will be close underwater monitoring and verification. Its level of efficacy would be very high, risk would be extremely low and it would likely be cost-effective, the researchers said. Jagdish Kadian, assistant professor at the Center for Artificial Intelligence and Robotics at IIT Mandi, said that learning about the ocean's internal currents from history led to the conclusion that only by placing instruments on research ships deep can one gain more insight into the ocean. Kadian, a co-author of the study, said that a typical cruise ship stays on the surface for a month or two, limiting the possibility of producing a comprehensive report on the sea. So it has often been said that changes in the sea do not wait for a ship ...
