What is Deepfake?
A deepfake is a type of synthetic media created using artificial intelligence (AI) techniques, particularly deep learning. The term "deepfake" is a combination of "deep learning" and "fake." These technologies allow for the creation of highly realistic images, videos, or audio that appear to depict people saying or doing things they never actually did.

How Deepfakes Work:
Deep Learning: Deepfakes are typically generated using neural networks, especially a type known as Generative Adversarial Networks (GANs). GANs involve two neural networks: a generator that creates fake data and a discriminator that tries to distinguish between real and fake data. Over time, the generator gets better at creating convincing fakes.

Face Swapping and Manipulation: In video deepfakes, the technology often involves mapping one person¡¯s face onto another¡¯s, allowing for the alteration of facial expressions, lip movements, and even speech patterns to match the desired audio.
