In an era of deepfakes and digital mistrust, some networks are building new tools to verify real people.

For example, dating app Tinder introduced a new Photo Verification feature in January 2020 that compares a series of real-time selfies to a cache of existing profile photos using both A.I. and humans. Those who pass the test receive a blue check mark verifying that the user is a real person.

Who and what is real online is becoming harder to determine, which is why authenticity is an important trend going forward.
