  1. Copies of a story, photos, and chat answers spread across the screen, and the name tags slide off them.

    The brief asks for proof.

    More clients want to know who made the art and what went into it.

  2. A gold thread runs from a photo to a video and sews a gold border around each one.

    Mark signs the final file.

    It adds C2PA 2.4 Content Credentials, the label your client asks for, with a signing time.

  3. A gold tag on the thread names who signed the work, with the blue Encypher badge on it.

    The label lists the sources.

    Source files the signer declares can link to their own labels. The check shows the sources the signer included.

  4. A magnifier rests on the unbroken blue Encypher badge, and a check mark appears beside it.

    Your client checks it.

    We agree on your client's checker up front, then test your real export.

Good questions.

Whose name goes on the file?
While you test, files carry the Encypher name. Your agency name needs an eligible paid plan and accepted proof of identity. Start free or see Mark pricing.
Does a watermark replace the credential?
No. A watermarkWatermark: A mark placed in the content itself, visible or hidden, so it can be found again after the file is copied. does not replace the source details your client asked for. Our audio and video examples show a valid credential. They do not show that a watermark survives re-encodingTranscoding: Converting media to a new format or quality, which changes its bytes and so breaks a hard binding..
Which versions and formats do you cover?
75+ formats for signing and verification. C2PA 2.4 is the default, and 76 of our 79 formats list it today. Our formal conformance record covers C2PA 2.2 over 20 media typesMIME type: The standard name for a file format, such as image/jpeg or audio/wav, that software uses to decide how to read a file.. It is not a 2.4 pass.
Who decides if the file is accepted?
Your client. We check the technical points you agreed on.
Why would a client trust your label?
Encypher wrote C2PA's standard for signing text and co-chairs the task force behind it. Our signing product is on the official C2PA Conforming Products ListConforming Products List: The C2PA's public record of products that passed its conformance program.. See the public record.
