Signature Protection Technology
Your Signature Is
Your Identity
Sigvera ensures no one can ever forge it.
The Facts
A Signature Is Easy to Copy and Hard to Disprove
Your signature looks the same on every page you sign. It's trivial to trace, scan, or paste into a document you've never seen, and proving that you did not sign can take years.
The biggest problem with traditional signatures: you use the same one every time.
The Solution
Cryptographic Protection for Every Signature
Sigvera generates a unique, cryptographically secure code for each document you sign. Instead of using a traditional signature that can be copied and reused, you write a Sigvera ink code: random, issued once, and registered to that one document. Each code is tied to a specific moment in time, so there's no signature pattern for anyone to steal.
- Each code is random, unique and single-use
- Instant verification by anyone, anywhere
- A time-stamped record of every code and verification
- Certificates and legal defense support for Pro members
How It Works
Three Steps to a Verifiable Signature
Protecting a signature takes about a minute
Generate
Request a unique ink code from our app or website. Each code comes from a cryptographically secure random generator and is issued only once.
Sign
Write your ink code on the document's signature line instead of a traditional signature. It takes seconds, and the code cannot be reused on any other document.
Protect
Capture a photo of your signed document. We store it securely as time-stamped evidence of what you signed, tied to that code.
