• Building a standard for cloud signatures

    A new industry consortium to pioneer open digital signatures for mobile and the web.


eIDAS and beyond

New regulations like eIDAS – European Union’s new Regulation on Identification and Trust Services – are setting rigorous requirements for secure signatures, in a way that is expected to influence the entire global industry.

The Cloud Signature Consortium aims to make it simple for EU businesses and governments to successfully comply with this new regulation. The vision is to create a single digital market, across Europe and the globe.

The Consortium

The Cloud Signature Consortium is a global group of industry, government, and academic organizations committed to driving standardization of highly secure and compliant digital signatures in the cloud.

Inspired by the rigorous requirements of the European Union’s Regulation on Identification and Trust Services (eIDAS), our common technical specification helps ease solution interoperability, streamlines compliance with e-signature regulations, and opens the market for uniform adoption of cloud-based digital signatures around  the world.

Changing the digital signature landscape

By simplifying and streamlining digital signing experiences, the Cloud Signature Consortium specification will have a remarkable impact on the cloud signature landscape. Here is what we intend to achieve.

Secure transactions, on the go

Our technical specification enables secure signing transactions through web browsers and mobile devices, from your desk or on the go!

Cloud storage, no download

Recipients will be able to easily sign documents stored in the cloud with any device, without having to download them first.

Simple certificate ownership

No complex renewal procedures, no risk of token loss or theft: keys and certificates will be fully managed by Trust Service Providers in the cloud.

Easy deployment for end users

Easier, faster, better! No more smart cards or USB tokens. No more drivers to install. No more client platform dependencies.

The Consortium members

The Cloud Signature Consortium is an international group of industry and academic experts, including solutions, technology, and trust service providers.

Paving the way for digital transformation

The new standard developed by the Cloud Signature Consortium will be critical to furthering digital transformation of business on a global scale, by giving everyone access to secure digital signature solutions, across a full range of cloud applications on mobile devices and the web. Once implemented, the technical standard will benefit processes where signer identification is critical, such as applying for a marriage or business license, social security benefits, or signing for a large loan.
