Apparatus and Methods for Verifying a File Origin

A computer-implemented method comprising:

• obtaining a hash of a file to be transmitted to a second apparatus and an indication of a file creator of the file;
• retrieving an identifier associated with the file creator;
• storing the hash of the file, associated with the identifier of the file creator, in an immutable ledger;
• obtaining the hash of the file from the second apparatus;
• verifying that the hash of the file is stored in the immutable ledger;
• retrieving, from the immutable ledger, the associated identifier of the file creator using the hash of the file;
• transmitting, to the second apparatus, a confirmation that the file is from the file creator;
• determining that the second apparatus has an associated identifier stored at the apparatus;
• providing a pairing invitation to the file creator to create a pairing link with the second apparatus;
• receiving an approval indication from the file creator to create the pairing link with the second apparatus;
• and
• creating the pairing link between the file creator and the second apparatus, the pairing link configured to permit file transmission between the file creator and the second apparatus.

One or more non-transitory computer-readable media storing instructions that, when executed by a computer, case the computer to:

• obtain a hash of a file to be transmitted to a second apparatus and an indication of a file creator of the file;
• retrieve an identifier associated with the file creator;
• store the hash of the file, associated with the identifier of the file creator, in an immutable ledger;
• obtain the hash of the file from the second apparatus;
• verify that the hash of the file is stored in the immutable ledger;
• retrieve, from the immutable ledger, the associated identifier of the file creator using the hash of the file;
• transmit, to the second apparatus, a confirmation that the file is from the file creator;
• determine that the second apparatus has an associated identifier stored at the apparatus;
• provide a pairing invitation to the file creator to create a pairing link with the second apparatus;
• receive an approval indication from the file creator to create the pairing link with the second apparatus;
• and
• create the pairing link between the file creator and the second apparatus, the pairing link configured to permit file transmission between the file creator and the second apparatus.
