Trust1Sign: Empowering Users with Secure, Local, and Compliant Digital Signatures
In an increasingly digital world, the need for secure and reliable digital signature solutions has never been greater. Whether for business contracts, legal documents, or personal agreements, the ability to sign documents digitally is a cornerstone of modern workflows.
Enter Trust1Sign, a cutting-edge solution developed by Trust1Team, designed to provide users with a seamless, secure, and compliant way to digitally sign documents in line with the eIDAS2 regulation. What sets SimpleSign apart is its commitment to privacy, open-source principles, a decentralized vision and empowering users to take control of their digital interactions.
What is Trust1Sign?
Trust1Sign is a digital signature solution that allows users to sign PDF documents electronically while adhering to the stringent security and compliance standards set by the eIDAS2 regulation (Electronic Identification, Authentication, and Trust Services). This regulation ensures that digital signatures are legally recognized across the European Union, providing the same level of validity as handwritten signatures.
The solution is designed with simplicity and security in mind, enabling users to sign documents quickly and efficiently without compromising on privacy or compliance. Whether you’re an individual, a small business, or a large enterprise, Trust1Sign offers a robust solution for all your digital signature needs.
Key Features of Trust1Sign
Free Signing with Physical TokensOne of the standout features of Trust1Sign is that users can sign documents for free as long as they use physical tokens. These tokens, such as smart cards or USB devices, provide an additional layer of security by ensuring that the signing process is tied to a physical object. This approach not only enhances security but also aligns with the eIDAS2 requirement for advanced electronic signatures.
Local Signing: Your Data Stays on Your DeviceIn an era where data privacy is paramount, Trust1Sign takes a bold stance by ensuring that your PDF documents are never shared with an online provider. Unlike many cloud-based solutions, SimpleSign processes everything locally on your device. This means your sensitive documents remain under your control, reducing the risk of unauthorized access or data breaches.
Built on Open Source and EU ContributionsTrust1Team is proud to build Trust1Sign on the foundation of open-source software and contributions from the European Union. By leveraging these resources, the solution not only benefits from the collective expertise of the global open-source community but also ensures transparency and trustworthiness. Moreover, Trust1Team is committed to giving back to society by contributing to the open-source ecosystem and supporting initiatives that promote digital innovation.
eIDAS2 ComplianceTrust1Sign is fully compliant with the eIDAS2 regulation, ensuring that all digital signatures created through the solution are legally binding and recognized across the EU. This compliance is crucial for businesses and individuals who require a high level of trust and legal certainty in their digital transactions.
User-Friendly InterfaceDespite its advanced features, Trust1Sign is designed to be intuitive and easy to use. The solution guides users through the signing process step-by-step, making it accessible even for those with limited technical expertise.
Why Choose Trust1Sign?
In a market saturated with digital signature solutions, Trust1Sign stands out for its unwavering commitment to privacy, security, and compliance. By keeping the signing process local and leveraging physical tokens, Trust1Team ensures that users retain full control over their data. Additionally, the solution’s reliance on open-source software and EU contributions reflects a dedication to transparency and community-driven innovation.
For businesses, Trust1Sign offers a cost-effective and secure way to handle digital signatures without relying on third-party cloud providers. For individuals, it provides peace of mind knowing that their documents are signed securely and in compliance with EU regulations.
This free approach demands from users to have smart card readers or certificates in the operating system available. The user-friendliness is not the same when using mobile wallets. A second important fact is that the reference implementation of the EU Commission is used as a PDF signature service. When approaching this, based on the previous fact, with the knowledge we have at Trust1Team, we smartly combine those technologies making us able to distribute this for free.
The business model for SimpleSign is based on mobile signature transactions, hence uplifting the usability. We integrated with Smart-ID, and you can contribute by using this mobile identity wallet and help us evolve this product for the B2B and B2C market.
