Hardware‑signed photos as provenance

Phone cameras can embed cryptographic signatures at capture time so a photo’s original sensor data is provably authentic and tamper‑evident. If exposed via standard APIs, these hardware‑signed photos let apps and services demonstrate that an image predates edits or generative content. — This reframes provenance from an optional label to a device‑level capability, shifting debates about deepfakes, evidence, platform moderation, and privacy toward hardware and platform policy.
