Verify an Only-Version Document
Check whether a document is legitimate.
Upload a file you received and SAIFE will compare it against registered Only-Version records to determine whether it is official, altered, unknown, revoked, superseded, or a possible imposter.
Public verification is frictionless and anonymous.
Upload the file you received. When anonymous verification is enabled, SAIFE checks the file against the Only-Version registry without requiring a login. If the file matches a registered document, the result will include the certificate proof link.
