The cryptographic service that provides the proof of the origin of data is known as Data Origin Authentication.

Here's how it works:

1. Digital Signature: The sender of the data creates a digital signature using their private key. This digital signature is unique to the sender and the data being sent.

2. Transmission: The sender then sends the data along with the digital signature to the recipient.

3. Verification: Upon receiving the data, the recipient uses the sender's public key to verify the digital signature. If the signature is valid, it proves that the data originated from the sender and wasn't tampered with during transmission.

So, Data Origin Authentication provides proof of the origin of data by using digital signatures.
