We solve all your doubts about digital certificates and electronic signatures

Interactive signature

What is the interactive signature service?

It is Uanataca's service to integrate the electronic signature in business and organisational processes for any type of document or transaction guaranteeing its integrity and authenticity. By integrating the signature API into your BMP, ERP or any application, you can have your employees, customers, suppliers or partners sign electronically without losing the current user experience. For the interactive signature, Uanataca digital certificates issued centrally in the SignCloud system are used, which guarantees the exclusive control of the signature key to its holder.

In what processes can I use the interactive signature service?

In all the processes of the organisation where it is necessary to provide identity and integrity to the documents that are sent or that are conserved, by legal compliance, to replace the handwritten signature by the electronic, by internal guarantees or by the need to generate electronic evidence to future. Some of the sectorial cases are:

  • Banking and Fintech: Signing of transactions, signing of certifications
  • Professional associations: Signing of certifications
  • Companies: requests to suppliers, delivery notes, publication of reports
  • Health: Signature of medical history and electronic prescription, signature of analysis reports and medical results
What electronic signature formats does the interactive signature service allow me?

The service allows you to make qualified electronic signatures in multiple formats and depending on the type of document you need to sign.

  • PDF documents: Electronic signature (PAdES-BES), Electronic signature with time stamp (PAdES-T), Long-term electronic signature (PAdES-LTV).
  • XML
How does the service guarantee the confidentiality of the documents to be signed?

Through the virtual machine that we deliver and install in your infrastructure, we guarantee the confidentiality of the information to be signed. The original documents are sent to the virtual machine, then it makes the calculation of the hash (mathematical algorithm that transforms data blocks into a new series of characters) and is sent to the Uanataca service where the pure electronic signature is produced . It is materially impossible to reconstruct the original document from the hash. Once the signed hash returns to the virtual machine, the electronically signed document is composed there. The original information never leaves your infrastructure.

Where is it stored and what certificate do I need for the interactive signature?

The interactive signing service requires that signatory users have a digital certificate. For this and through the system of issuing digital certificates, companies or organizations may issue digital certificates in the SignCloud centralisation system, always guaranteeing the user exclusive control of their private key.

How do I know how many interactive signatures I have made in a period of time?
