Building a standard for cloud signatures
A new industry consortium to pioneer open digital signatures for mobile and the web
#OpenSignature
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 group of industry and academic organizations committed to building a new standard for cloud-based digital signatures that will support web and mobile applications and comply with the most demanding electronic signature regulations in the world.
The goal is to provide a common technical specification that will make solutions interoperable and suitable for uniform adoption in the global market.
This effort was inspired by the need to meet the highest level requirements of the European Union’s Regulation on Identification and Trust Services (eIDAS), but its impact is expected to be global as demand for highly secure digital solutions continues to rise.
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.
