Deepfakes aren’t a new marvels and have been around for a while. still, advancement in technology have made them rather sophisticated. lately, Indian actor Rashmika Mandana’s deepfake videotape surfaced and in the history numerous celebrities have been targets of similar vids. We explain what are deepfake videos, how they’re made and how to spot them:
What are deepfakes?
Deepfakes are manipulated media, generally videos, created using artificial intelligence( AI) ways to replace a person’s likeness or voice with someone else, making it appear as if they said or did effects they never did.
How are deepfake videos made?
Deepfakes are made using a combination of encoder and decoder networks, frequently in the environment of a Generative Adversarial Network( GAN). The encoder network analyses the source content(e.g., the original face) and excerpts essential features and representations.
These features are also passed to the decoder network, which generates new content, similar as a manipulated face.
The process is repeated continuously till AI gets right.
In the case of videotape deepfakes, this process is repeated for each frame of the videotape to insure durability. GANs operate by having a creator network that creates fake content and a discriminator network that tries to distinguish fake content from real content.
How to spot deepfakes?
To spot deepfakes, you can look for visual and audio inconsistencies, as well as other reflective signs.
Look for facial expressions, anomalies.Check for unnatural facial expressions, mismatched lip- sync, or blinking irregularities.hear to the audio precisely to spot disagreement.
When you’re in mistrustfulness about a videotape, look for audio disagreement. hear for shifts in tone, pitch, or unnatural speech patterns.
Check for the surroundings where the videotape is shot.
Look for visual deformations, blurring, or inconsistent lighting. See if the person in the videotape can be in those surroundings or not.
environment and content are the most important.
Analyse whether the geste or statements align with the existent’s given characteristics. A Barrack Obama will noway be seen in a videotape using certain type of language about, say, a Donald Trump
