AI Image & Media Authenticity Checker – C2PA Verifier
Check images, videos, and audio for Content Credentials, C2PA provenance, AI-use declarations, signatures, file integrity, metadata, and technical media information.
This authenticity checker examines an uploaded image, video, or audio file for Content Credentials, C2PA provenance records, signed creation and editing information, declared AI usage, file integrity, metadata, and technical media details. Unlike visual detectors that return an unsupported AI probability, it prioritizes verifiable evidence contained in or associated with the file.
A More Honest Alternative to Percentage-Based AI Detectors
Many online AI image detectors claim that a file is a specific percentage AI-generated based on visual patterns. Those estimates can be unreliable after compression, resizing, screenshots, editing, or social-media processing. This utility does not invent a confidence score. It examines cryptographic provenance, signed declarations, file structure, metadata, and other technical evidence, then clearly explains what can and cannot be concluded.
Check Content Credentials and C2PA Provenance
Content Credentials are provenance records commonly based on the C2PA standard. When present, they may identify the application, device, creator tool, organization, or service involved in creating or modifying a file. They may also record editing actions, ingredients, AI-assisted changes, and whether the current file still matches the signed asset.
Check Whether AI Usage Was Declared
Valid Content Credentials may declare that generative AI created or modified part of an image, video, or audio file. The checker is designed to show these declarations separately from technical observations. A declaration can provide valuable provenance evidence, but it does not independently prove that every visible or audible element is truthful.
Verify File Format and Integrity
The server detects the actual media format from the file bytes instead of trusting only the filename or browser-provided MIME type. It also calculates a SHA-256 hash that uniquely identifies the exact uploaded file. If the extension does not match the detected format, the report highlights that inconsistency.
Images, Videos, and Audio Files
The checker accepts JPG, JPEG, PNG, WebP, AVIF, HEIC, HEIF, MP4, MOV, MP3, M4A, WAV, and FLAC files. A single analysis workflow applies the same evidence-based approach to still images, video, and audio while reporting technical details appropriate to the detected media type.
What Missing Content Credentials Mean
When no readable Content Credentials are found, the correct result is inconclusive. The file may never have contained credentials, or they may have been removed during editing, exporting, compression, screenshotting, messaging, downloading, or social-media re-encoding. Missing credentials do not prove that a file is authentic, fake, AI-generated, manipulated, or human-created.
What Valid Content Credentials Prove
Successfully validated credentials can provide strong evidence that a signed provenance record belongs to the current asset and has not been altered in a way that breaks the signature. They verify the provenance record and file relationship. They do not prove that a photographed event happened, that a depicted person is genuine, or that every factual claim in the media is true.
Private Temporary Server Processing
The file is uploaded because cryptographic C2PA inspection and cross-media analysis require server-side processing. ORVITech writes it to an isolated temporary workspace, analyzes it, returns the report, and deletes the workspace after the request finishes. The file is not added to an account or intentionally retained as permanent storage.
Why the Analysis May Wait Before Uploading
Large media analysis requires temporary processing capacity. Before uploading, the utility reserves enough server space for the selected file and analysis workload. If other large files are already being processed, the request waits transparently until sufficient capacity becomes available. The upload begins automatically after the reservation is ready.
How to Check Whether an Image Is AI-Generated
Select an image, video, or audio file and click Check Authenticity. The utility reserves processing capacity, uploads the file, detects its actual format, calculates its SHA-256 hash, and checks for Content Credentials and C2PA provenance. The report then explains the available evidence without claiming more certainty than the file supports.
Media Authenticity Check Example
Suppose you upload a JPEG exported from an AI-assisted editing application. If the file contains valid Content Credentials, the final report may identify the signed provenance record, claim generator, declared editing actions, and a generative-AI declaration. If the same image was later screenshot or passed through a platform that removed its credentials, the report may instead say that no readable Content Credentials were found. That second result is inconclusive rather than proof that the image is authentic or fake.
Frequently Asked Questions
Can this tool tell whether an image was created by AI?
It can identify AI generation or AI-assisted editing when that information is declared in valid Content Credentials or supported metadata. If the file contains no reliable declaration or provenance evidence, the tool cannot honestly prove whether it was created by AI.
What are Content Credentials?
Content Credentials are provenance records that can describe how digital media was created or modified, which tools were involved, and whether generative AI was declared. They commonly use the C2PA technical standard and cryptographic signatures.
What is C2PA?
C2PA is a technical standard for attaching signed provenance information to digital content. A C2PA manifest can contain claims, assertions, editing actions, signer information, ingredients, AI-use declarations, and validation information.
Does a valid C2PA signature prove that an image is real?
No. A valid signature can verify the signed provenance record and its relationship to the file. It does not independently prove that the depicted event happened, that a person is genuine, or that the media communicates a truthful claim.
What does it mean when no Content Credentials are found?
It means the file does not contain readable credentials that the checker can detect. Credentials may never have existed, or they may have been removed by editing software, exporting, screenshots, messaging applications, websites, or social networks.
Can Content Credentials be removed?
Yes. Re-exporting, recompressing, screenshotting, copying media into another container, or uploading it through some platforms can remove Content Credentials and traditional metadata.
Can this tool detect deepfake videos?
The tool can inspect provenance, signed declarations, file integrity, metadata, and technical evidence associated with a video. It does not promise universal deepfake detection based only on visual or audio appearance.
Why does the checker calculate a SHA-256 hash?
SHA-256 creates a collision-resistant cryptographic fingerprint of the uploaded file. Even a very small modification normally produces a completely different hash, making it useful for identifying and comparing exact file versions.
Why does the checker inspect the file format from its bytes?
A filename and browser MIME type can be incorrect or misleading. Detecting the format from the binary file signature provides stronger evidence about what type of media was actually uploaded.
What happens when the file extension does not match its format?
The report marks the mismatch as a technical inconsistency. A mismatch may result from accidental renaming, an incorrect export, file conversion, or deliberate disguise, but it is not automatically proof of malicious manipulation.
What file types are supported?
The checker currently accepts JPG, JPEG, PNG, WebP, AVIF, HEIC, HEIF, MP4, MOV, MP3, M4A, WAV, and FLAC files.
What is the maximum file size?
You can upload one supported image, video, or audio file up to 500 MB.
Why might my file wait before the upload starts?
The utility reserves temporary processing capacity before uploading. If other large jobs are already using the available capacity, the reservation waits until enough space becomes available and then starts automatically.
Is my uploaded file stored permanently?
No. The file is processed in an isolated temporary workspace and deleted after the analysis request finishes. It is not intentionally retained as permanent storage.
Can I use this authenticity report as legal proof?
No. The report is an informational technical analysis. Legal, journalistic, insurance, law-enforcement, or forensic decisions should involve qualified specialists and proper preservation of the original evidence.
Does missing EXIF metadata mean an image is fake?
No. Editing applications, websites, messaging platforms, social networks, compression tools, and export settings commonly remove EXIF and other metadata.
Can a genuine photograph contain AI editing?
Yes. A photograph may originate from a camera and later receive generative fill, object removal, enhancement, upscaling, background replacement, or other AI-assisted edits. Provenance records can help distinguish original capture from later transformations when those actions are declared.
