How Verification Works

Upload a PDF certificate or C2PA-signed JPEG — file type is auto-detected
PDF: Server extracts embedded image, recalculates hashes, and verifies on blockchain
JPEG: Server reads C2PA Content Credentials, extracts Captilo assertions, and cross-verifies on Sonic blockchain
Results are returned and your file is immediately deleted from the server
