Our patent

Yozons™ invented web-based electronic signature products in which end users do not have to generate, maintain or keep secure the digital signing keys used for creating provably reliable electronic records. Competing technology providers -- including today's digitally signed e-mail, SSL/HTTPS, PGP and SSH -- rely on a public key infrastructure (PKI) or similar system that requires data signers generate their own key pairs, transfer the public keys to the recipient and/or have the public key certified by another party who issues a digital certificate or otherwise vouches for the owner of the public key using a pre-established "chain of trust."

Yozons merged these technologies into the server, allowing users to be dynamically authenticated in various ways (such as post business process verification, email-based authentication, password-protected transactions or the use of other authentication systems that use credit or other personal information databases) without users having to be pre-established or generate keys or acquire digital certificate credentials before using the digital signing solution. Instead, the server generates and keeps secure the encryption keys used in digital signatures applied on behalf of its users.

This invention is protected by U.S. Patent No. 7,360,079 and is assigned to Yozons. The provisional patent was filed on January 5, 2001. The patent application was filed January 4, 2002. The patent was issued on April 15, 2008. Read our press release.

Licensing terms

Most electronic signature solutions that reach outside a controlled network of pre-authorized parties are impractical if they rely on a PKI, digital certificates and/or user-managed keys. Fortunately, Yozons offers a reasonable, low cost royalty program so you don't have to.

Yozons licenses our patent to those who negotiate a standard royalty agreement using a simple, perpetual, one-time $10,000 fee per product, whether it is used in-house, sold as licensed software, or offered as a service. Of course, those who license any of our Yozons technologies are already covered.
