The Dhaka Times Desk Recently there are complaints of fake video calls. Through the use of technology, many use someone else's face instead of their own through fake video calls. It is important to identify these calls. So how do you do it?
The background behind the video or any important feature of the video can be artificially changed through it. Learn how to spot fake video calls today.
Basically fake video calls can be of various types. For example, someone created a fake background behind him in a video call. Additionally, you can record a video of yourself looking at the monitor and play it during the meeting. Where there is no need to speak. Many also add YouTube videos to the webcam input in live video calls. Again, many people make fake video calls even using deepfake technology. By using artificial intelligence technology, it is also possible to change the face and voice on the display. These fake live videos are created with the help of some software.
Deepfake technology
Deepfakes created using artificial intelligence may look believable, but it creates fake videos. Due to the continuous development of deepfake technology, it is becoming increasingly difficult to distinguish between a real video and an AI-generated video.
How to identify fake video calls
In case of a fake video, you can tell that it is fake by looking at its quality. Especially in the case of deepfake, if you look at the videos so far, you can understand that they are fake. But in other cases it can be difficult to detect fake video calls. In that case, let's also take a look at some ways to identify a fake video call.
Video quality
Fake videos generally have poor quality. Moreover, it is possible to understand whether the video is fake or not by testing watermarks or other marks.
Video Sizing
During fake video calls, the video is usually resized to fit the webcam window or the app being used. When resizing the video, the aspect ratio of the video is distorted. This can make the face look extra long or extra wide.
Contacts
Note whether the person is calling from your acquaintance or contact list. If not, check if the name sounds strange. Also, check if any app name comes up under Contacts.
Loop and cut
Many fake videos go back to the beginning after a certain amount of time has passed and continue to loop. That is, the video keeps looping. Also, the video ends abruptly at the end, but the video call does not end. Even so, it can be assumed to be a fake video call.
And if one uses a face swapping app, there is very little chance that the swapped face will fit correctly.
Fake calls made with software like Menicam can appear quite believable. But unless you're using very high-end hardware, they're pretty easy to detect.
On the other hand, making fake video calls on smartphones is not very easy. It also has various limitations. Mobile apps like WhatsApp and FaceTime also have built-in security measures to prevent fake video calling and other such scams. But the last thing is, if you check the phone number, video quality and such information well, you can catch them very easily.

How to prevent dengue
Dengue is a mosquito-borne viral fever. This fever is different from other viral or bacterial fevers. However, this fever is not contagious in any way. This viral fever can occur alone or in combination with other viruses (chikungunya, yellow fever, Burma forest, flu, respiratory syncytial) and bacteria (pneumococcus).
Dengue fever is divided into two categories depending on the severity of symptoms and fever.
1. Common dengue fever
2. Dengue fever with bleeding.
In the case of common dengue fever, the following symptoms are mainly seen-
1. Sudden high fever lasting 2 to 7 days.
2. Severe headache.
3. Pain behind the eyes.
4. Along with the fever, red rash appears all over the body.
5. Severe pain in whole body as well as back pain.
6. Nausea or vomiting.
7. A rash or red bumps on the skin.
In case of dengue fever with bleeding:
1. Bleeding from nose, mouth or vomiting with high fever within 2 to 48 hours.
2. Fluid accumulation in chest or abdomen along with fever.
If any of these symptoms appear, seek medical attention immediately.
On the other hand
Wait at home for the first 3 days of fever. On the other hand, sponge the whole body with water every now and then. This will reduce the level of fever. Drink enough water and rest. After that, if the fever does not decrease or if it continues to increase after some time, consult a doctor immediately.
Things to do to prevent Dengue:
1. Try to keep the surroundings of the house as clean as possible.
2. If there are flower tubs or broken plastic bottles, can shells, tires or polythene inside the house, clean them quickly and drain the accumulated water from the flower tubs.
3. Spray or fog at least 3 times a week to kill mosquitoes.
4. You can keep mosquito repellent cream with you while going out.
5. After evening, younger and older members of the household should use mosquito nets.
6. Clean up any accumulated rain water, as this is the time when Aedes mosquitoes lay their eggs.
7. On the other hand, you can use mats along with mosquito nets to avoid mosquito infestation.
8. Since Aedes mosquitoes bite during the day, it is important to avoid sleeping with mosquito nets while sleeping during the day. Source: https://dmpnews.org
