What is Durable Medium

?

It is a legal concept introduced by the European Union in 2017. It requires financial institutions to provide their clients with documents using a durable information medium, which guarantees the invariability of records and access to them also after the end of the client’s cooperation with a given institution. The most popular by now and very expensive are: paper, CD/DVD, pendrive, WORM matrix.

The functionality of our Platform allows replacing the traditional mass mailing to your customers by providing access to the content of transferred information. It meets the legal requirements of banks, investment funds, and other financial institutions. Their customer gains access to the information stored in the file through the distribution system (e.g. STI 24) or a link provided by SMS or e-mail.

The files are placed on a specially prepared DM Platform that provides:

  • permanent saving of information intended for the customer without the possibility of modification, deletion or concealment

  • zero possibility of invisible deletion/withdrawal of access to information designed for the customer by both the fund and the customer – for the period required by law

  • access to information designed for the customer also when his agreement has expired.

Durable Medium

by dBridge

Access to documents on a Durable Medium based on blockchain is available on dBridge Platform. The solution guarantees the integrity, security and non-repudiation of the information stored in the documents stored in a cloud. The document published on our platform is divided into encrypted fragments, of a fixed size, and then these

fragments are separately recorded in transactions on distributed registers. Submitting the original document as a whole requires downloading information and relevant fragments from the Platform, which can only be done by the institution and the client of this institution.

Publishing

document on a platform

Sending a notification

with decoding keys to the client

(e-mail, text, push notification in the mobile app)

Collecting decoding keys

by the client

Downloading a document

by the Platform client using the link and codes

If the client loses the links to documents, it is possible to log in on the Platform.

If a contract with the client is terminated, the user will be able to use the portal of historical data,
which will always be working, regardless of whether the source system that powers the Platform with documents is working.

  • Bespoke solution with client’s needs

How to implement our solution

?

Our DM Platform has all the features of a durable medium such as WORM matrix, but at the same time guarantees much lower costs of implementation and maintenance. Also – contrary to the WORM matrix – it ensures the lack of possibility to remove documents, and provides multi-node clusters of efficiency and reliability, as well as the high level of re-duplication of the document content.

The platform is implemented in two models

Bespoke in the cloud or on-premises

The solution is usually tailored to our Client’s needs: dBridge implements the Platform on the existed IT environment which finally manages the Platform. The Client should also provide the correct interfaces for transferring documents to/from the Platform.

SaaS

dBridge ensures access to the Platform in the Managed Services model, using our own data processing centre. We ensure access to documents also after the expiration of of the contract. The Client needs to ensure the proper interfaces for transferring documents to/from the Platform. It is also possible to share Client’s documents through the Client’s platform (e.g. online banking) via API to our Platform.

Business models

  • SaaS for SMEs (per each page of a document or bulk of documentsor per GB storage)

  • Bespoke solution for enterprises (per user and per GB storage)

  • On premise for enterprises
