Why has "content provenance" become a pressing problem in the age of generative AI?

Because AI now produces photos and videos so convincing — the "puffer-jacket Pope," fake Tom Cruise deepfakes — that we can no longer tell real media from synthetic by looking.

Generative models can fabricate realistic images, voices, and video of real people doing things they never did. When seeing is no longer believing, society needs a technical way to answer two questions:

• Where did this come from? (provenance — the origin and history)
• Has it been altered since? (authenticity / integrity)

Provenance is the verifiable record of an asset's origin and every edit along the way. Rather than trying to detect fakes after the fact (an arms race you lose), the idea is to prove the authentic ones — attach tamper-evident history to genuine content at the source.

Tip: The strategy flips the problem: don't hunt for fakes, certify the real thing. Absence of credentials becomes the warning sign.
