Electronic Trust Services

In a digital environment where the authenticity and integrity of information are critical, electronic trust services provide the technical and legal mechanisms to guarantee that a document, signature, or key existed at a specific moment and have not been altered since then.

CertiSur offers three complementary services that cover the needs of organizations that must demonstrate the validity of their digital processes to third parties, regulatory bodies, or judicial authorities.

Timestamp — Time Seal

The Timestamp service allows you to attach a "reliable date" to your documents, ensuring the integrity and authenticity of each signature. It is issued by a trusted Time Stamping Authority (TSA) and has full legal backing.

With CertiSur's Timestamp you can:

• Determine the existence of a document with respect to a specific date.
• Guarantee the integrity of the document—that it has not been modified—from that date.
• Extend the validity of signed documents for an extended period of time.

LTV — Long Time Validation

LTV (Long Time Validation) ensures the validity of certificates by incorporating an accurate record of each certificate's status at the moment of signature. This allows you to verify digital signatures many years after the original certificates have expired or been revoked.

Key features:

• Centralized and secure control of keys.
• Allows the use of time seals for each signature.
• Support for multiple signers in the same workflow.

Key custody

Protect your keys with our custody solution. Securely deposit the keys needed to decrypt your data, ensuring that only authorized persons or systems can access the protected information—even in contingency situations.

Key features:

• Confidentiality of biometric and sensitive data.
• Secure custody of encryption keys with controlled access.
• Recovery of encrypted data in case of loss or contingency events.

• Grant legal and evidentiary validity to your digital documents.
• Guarantee the integrity of information over the long term.
• Comply with regulatory and audit requirements.
• Protect encryption keys against unauthorized access.
• Ensure data recovery in case of contingency events.
• Extend the validity of digital signatures beyond the certificate lifecycle.
• Simplify the demonstration of existence and integrity in legal proceedings.

Electronic Trust Services are essential for organizations that operate with:

• Contracts and documents with long-term legal validity.
• Digital files in public organizations and regulated entities.
• Accounting, tax, and audit records.
• Filing systems for electronic and digital signatures.
• Biometric identity management.
• Financial and banking processes with traceability requirements.
• Medical records and digital medical documentation.
• Any process where authenticity and integrity must be demonstrated to third parties.
