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.
eIDAS and beyond
Regulations like eIDAS – European Union’s Regulation on Identification and Trust Services – are setting rigorous requirements for secure signatures, in a way that is influencing the entire global industry.
The Cloud Signature Consortium aims to make it simple for businesses and governments to successfully comply with regulations like eIDAS. Our vision is to create a single digital market, across Europe, and 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 standard developed by the Cloud Signature Consortium is 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. The technical standard benefits processes where signer identification is critical, such as business contracts, social security benefits, or loans.
