Digital signature with biometric data
Our solution goes beyond appearance. It captures the essence of the signature and offers a seamless experience.
Advanced signature capture
We capture not just the image of the signature, but the dynamic parameters that make it unique and inimitable.
Signing experience
We eliminate friction in the digital signing process to make it as natural as paper.
How does a signing project with MobbSign work?
Key generation and trust model
Before any signature is made, the system generates a unique pair of asymmetric keys for the session. The public key is linked to the document and the signer, while the private key is held by a certified Trust Service Provider (TSP), ensuring the chain of custody from the very first moment.
Opening, reading and signing execution
The signer views the entire document on a mobile device before signing. The handwritten signature gesture is captured with all its dynamic richness: pressure, speed, coordinates, rhythm, and duration, generating a unique biometric trace linked to that specific document.
Biometric capture and local processing
All biometric processing occurs exclusively on the device where the signer signs, locally. Raw signature data never travels across the network. This privacy-by-design principle ensures that the most sensitive information never leaves the terminal without cryptographic protection.
Asymmetric encryption, hash and time stamp
The cryptographic core of the process: biometric data is encrypted locally with the TSP's public key. Simultaneously, a SHA-256 hash of the document is generated. Everything is encapsulated in a secure signature object with encrypted biometrics, hash, evidence, and a certified time stamp.
Signed PDF composition and delivery
The signature object is embedded into the original PDF, creating a self-sufficient document with full legal validity under the eIDAS Regulation. The resulting PDF contains all the necessary evidence for verification at any time, without depending on external systems.

A signature that defines and identifies
It’s not just about what the user draws, but how they do it. Each stroke incorporates biometric parameters that turn the signature into unique evidence.
Biometric Signature:
Advanced Electronic
Our solution fully complies with the eIDAS Regulation, guaranteeing maximum legal validity for every signed document.
Standard Guarantees
Unique Link
Biometric data and the signature graph are unequivocally associated with a single person.
