No. Private client information is never exposed to the public accountant during the Proof-of-Reserves attestation process.
Ledn creates a unique anonymized hashed ID for every client reference number - and for every new attestation. This hashed ID is matched with each account's balances for the attestation. This allows TNF to produce individually verifiable proofs for each Ledn account balance without ever having access to any sensitive personal information, thereby protecting client confidentiality.
The unique hash ID is then provided to each client with a balance, so that they can verify their balance was included in the attestation on the public accountant's website.
