How would you spot a deep fake?

I would start with the eye movement. If the eye movement looks unnatural or lack of eye movement such as absence of blinking, there are red flags. It is challenging to replicate the act of blinking in a way that looks natural.

When something doesn’t look right about a face, it could signal facial morphing. This occurs when a simple stitch of one image has been done over another.

We can also spot facial morphing if someone’s face doesn’t seem to exhibit the emotion that should go along with what they’re supposedly saying.

Another sign is if a person’s body shape doesn’t look natural or there is awkward or inconsistent positioning of head and body. This may be one of the easier inconsistencies to spot because deep-fake technology usually focuses on facial features rather than the whole body. Abnormal skin tone, discoloration, weird lighting, and misplaced shadows are all signs that what you’re seeing is likely fake.

If someone looks distorted or off when they turn to the side or move their head, or their movements are jerky and disjointed from one frame to the next, you should suspect the video is fake.

Deep-fake creators usually spend more time on the video images rather than the audio. The result can be poor lip-syncing, robotic-sounding voices, strange word pronunciation, digital background noise, or even the absence of audio.

I would look for the above signs and if I see such similarities in a picture or video chances are it is more than likely a deep fake.
