Register your object with a unique digital identity, linked to a processed image with QR and backed by verifiable proof. The record can be used to document your collection, preserve documents, record history, support insurance processes or facilitate future verifications.
Each registered object receives a unique ISCN code, intended as a stable identifier over time, and a processed image with QR. The system generates technical hashes of the file and creates blockchain proof verifiable through OpenTimestamps, to support the date and integrity of the record.

— Stockholm, Sverige —
ISCN is an organization based in Stockholm, Sweden, dedicated to the digital registration of valuables and collectibles. Our mission is to document each object through a unique code, a processed image with QR, technical hashes and blockchain proof, helping preserve its information and facilitate future verifications.
ISCN applies GDPR rules rigorously. We do not share information with third parties.
Registration can be carried out privately, linked only to an email address and a personal password. We do not request unnecessary personal data, and record information is preserved in an encrypted digital environment hosted only on European servers within the European Union.
If you want to show a registered object, you can share its ISCN code. Through the code verification service, anyone with that code can consult the public object record and review the associated verifiable information.
If you lose or forget your password, we will help you recover access through a secure verification process. To protect your records, recovery is handled through the registered email address and checks intended to confirm that you are the person authorized to access the stored information.
ISCN works to keep the information in your records protected and available over time.
