Welcome to OpenSBR
Inline XBRL electronic signature

Introduction

Inline XBRL is an important open standard for the exchange of (financial) reporting information. With an increasing number of regulators mandating Inline XBRL, being able to proof the integrity is important.

Together with GLEIF and XBRL International, OpenSBR drafted a specification for a digital signature on Inline XBRL, based on existing open standards and specifications.

Documents can be signed with X.509 certificates, including GLEIF certificates (tying a signed document to the Legal Entity Identifier of an organization). The specification relies on open standards such as X.509, XML-DSig and XAdES.

OpenSBR also created draft reference implementations for signing and verification of electronic signatures.

Documentation

A first draft of the approach, specification and manual is available on request.

Open source software

Signing & verification

A desktop tool (Windows application .NET C#) for signing and verification of signed documents is available.

The desktop tool can be downloaded here (version 20190429).

The source code, including a platform-independant library (.NET Core C#) will be available on our GitHub page.

Browser verification

A browser extensions for the verification and inspection of the signature and authenticity of the content, will be published soon.

The proof of concept is available in the Chrome Store.
