Check C2PA Content Credentials
— Free
C2PA is the open standard for digitally signing media with a verified provenance chain. Upload any image and FakeRadar will tell you whether it carries valid content credentials, who signed it, and what changes were made.

What is C2PA?
C2PA (Coalition for Content Provenance and Authenticity) is an open technical standard that embeds a cryptographically signed manifest inside media files. This manifest records who created the content, which tools were used, when it was captured or generated, and what edits were applied.
Think of it as a tamper-evident seal. If the image is modified after signing without re-signing, the credential becomes invalid — giving you a reliable signal that something changed.
C2PA is rapidly being adopted by camera manufacturers, AI platforms, and major media organisations as a foundational layer of digital trust.

What FakeRadar shows you
Valid credentials
The image carries a C2PA manifest and the cryptographic signature is intact. The provenance chain — creator, tool, timestamp, edits — matches the embedded record. This is the strongest positive signal.
Invalid credentials
A C2PA manifest is present but the signature verification failed. This means the file was modified after signing without updating the credential — a significant red flag for content integrity.
Credentials stripped
Forensic signals suggest a C2PA manifest may have existed but was removed. Stripping credentials is a common step in workflows that misrepresent the origin of content.
No credentials
The image does not contain a C2PA manifest. This is normal for most existing images — C2PA adoption is still growing. The absence of credentials alone is not evidence of manipulation.

Five Signals
C2PA is just one of five signals FakeRadar checks
Content credentials are powerful — but most images in circulation don't carry them yet. FakeRadar runs four additional forensic checks alongside C2PA to give you a fuller picture.
Error Level Analysis
Detects compression inconsistencies that indicate compositing or AI generation artefacts.
Frequency Domain Analysis
Reveals synthetic repeating patterns invisible to the human eye in the image's frequency spectrum.
Metadata Inspection
Reads camera model, GPS, timestamps, and software fields for anomalies and inconsistencies.
Hive AI Detection
Industry-leading deep-learning model trained specifically to detect AI-generated and deepfake images.
