PartisanFinancial data integrity infrastructure
Partisan records a file's fingerprint without seeing or keeping the document, gives a dated receipt, and shows a file is unchanged since it was recorded.
Sample receipt. Example data only.
- For
- Insolvency practitioners
- Law firms
- Compliance teams
- Forensic accountants
- Investigators and asset recovery
Paid pilot online. One PDF up to 5MB. Secure checkout by Stripe.
Your document is never seen or stored. Partisan records only its fingerprint.
How it worksThree steps
Record a file
Only its fingerprint is taken. The document itself is not seen or kept.
Receive a dated receipt
It is kept separately from your own records.
Check the file later
Check it against the receipt. A single changed figure shows up as a mismatch.
Backdated documents, disputed invoices and recent court judgments in Jersey and the BVI keep coming back to one question about records: is this the same file that was handed over? Partisan gives you a simple way to answer it.

QuestionsFrequently asked
Does Partisan see my document?
Partisan records a file's fingerprint without seeing or keeping the document, gives a dated receipt, and shows a file is unchanged since it was recorded. Only the fingerprint is recorded.
What is a fingerprint?
A short string worked out from the exact contents of a file. Change a single figure and the fingerprint changes, so the check shows a mismatch.
What is on the receipt?
A reference, the file name you gave, the fingerprint, and the date and time it was recorded.
Can we check a file without relying on Partisan?
You can get the same fingerprint yourself in CyberChef, so you are not relying only on Partisan.
What does it not show?
It does not show that the contents are true, who wrote the file, or when the file was first created.
How is Full-file different?
Full-file fingerprinting covers the entire document. Its contents stay protected by your own private key encryption, so Partisan cannot see them.
What can I record with the £45 sample?
One PDF up to 5MB. It is the quickest way to see the receipt and try the check for yourself.
