Safe Stamper services, provided by Safe Creative, offer advanced tools for generating electronic evidence with international legal standing.

Guarantees of Integrity and Certain Date

Every piece of evidence generated by Safe Stamper guarantees the integrity of the content and the precision of its timestamp. This security is built upon three fundamental pillars:

1. Qualified Electronic Timestamps (eIDAS): The date and time of each deposit are backed by a Qualified Trust Service Provider under the EU Regulation 910/2014 (eIDAS). This provider is technically and administratively independent of Safe Stamper, granting the evidence maximum evidentiary weight across European jurisdictions.

2. Inalterability via Electronic Signature: All deposited information is secured with an electronic signature issued by an independent qualified provider. This ensures that the document has not been altered since the moment of certification.

3. Blockchain Audit Trail: We further reinforce these guarantees through a daily audit process on the Ethereum blockchain. By registering the digital footprint (hash) of the evidence on a decentralised network, we provide an additional layer of security that makes the proof forensically indisputable, even in jurisdictions where European regulations may not directly apply.

This combination of European regulatory compliance and blockchain technology ensures comprehensive legal protection for potential litigation in any nation.

The NOM 151 (Official Mexican Standard 151) is a fundamental technical and legal standard in Mexico. Its primary purpose is to guarantee that an electronic document - such as a contract, file, or screenshot - has remained unaltered since its creation and existed at a specific date and time.

Unlike a standard timestamp, NOM 151 complies with the rigorous requirements set by the Mexican Commercial Code and tax authorities (SAT). This provides digital evidence with "certain date" (fecha cierta) and integrity, making it legally robust.

Integration for Users in Mexico and International Stakeholders

Safe Stamper has integrated the simultaneous issuance of the NOM 151 certificate across all its services, including file certification, email tracking, web browsing captures, and electronic signatures.

This integration offers several key advantages:

• Full Legal Validity: Evidence generated carries maximum evidentiary weight in Mexican courts. This often eliminates the need for complex digital forensics to prove a file has not been tampered with.
• Dual-Layer Security: For file certifications, Safe Stamper generates two separate records: one for the platform’s certificate and another directly for the original file. This ensures both the "container" and the "content" are indisputable.
• Streamlined Process: Users receive this legal guarantee automatically. There is no need to separately engage a Certification Service Provider (Prestador de Servicios de Certificación or PSC).

Why it Matters

This report is essential for any entity managing digital assets, contracts, or intellectual property in Mexico. It effectively "bulletproofs" evidence against potential legal challenges or disputes. While NOM 151 is a Mexican standard, its function is analogous to "Qualified Electronic Timestamps" under European eIDAS regulations, providing a high level of assurance regarding data integrity and temporal existence.

Safe Creative provides essential tools for the protection of intellectual property. These tools include registration certificates and technical evidence, designed to establish irrefutable proof of authorship and ownership. Below is a summary of the key features and how to obtain them.

1. Types of Certificates

Safe Creative offers three types of certificates to support the authorship and rights of registered works:

• Certificate of Inscription: A technical document that proves the identity and integrity of the work using a triple identification system (SHA1, SHA256, and SHA512) and double time-stamping to guarantee the exact date and time of registration.

• Registration Certificate: Provides a summary of the information stored in Safe Creative, including the registration code, title, author, registration date, and reserved rights.

• Creative Process Certificate: Consolidates all development materials—such as sketches, drafts, and notes—each dated and time-stamped to demonstrate the creative evolution of the work.

2. Technical Evidence

Safe Creative provides technical evidence to confirm the date of possession and rights declarations. These are crucial for legal proceedings or arbitration and include:

1. Original Work Identification: The original file (or description) linked to three unique digital fingerprints (SHA1, SHA256, SHA512).

2. Double Time-Stamping: Verification of the precise moment the registration took place.

3. Certified Documentation: Documents signed and sealed by Safe Creative reflecting the rights declarations made by the user.

How to Download Certificates and Evidence

To download your registration documents, follow these steps:

1. Go to the "Works" section.

2. Select the work by clicking on its title or thumbnail.

3. In the "Actions / Certificates" menu, choose the specific evidence you require.

Language Support: Certificates can be generated in multiple languages, including English, Spanish, Italian, French, Portuguese, German, Dutch, Polish, Russian, Arabic, Chinese, Japanese, Hindi, Catalan, Basque, and Galician.

Bulk Management: For multiple works, you can select them simultaneously and use the "Manage Selected" option to download several certificates or pieces of evidence at once.

How Blockchain Audit Registration Works

The incorporation of Blockchain technology into Safe Creative adds an unquestionable audit process due to the public and immutable nature of the blockchain. It has been implemented in such a way that this same strength does not compromise the privacy rights of Safe Creative users.

The audit system generates an electronic document in XML format every 24 hours, containing the relationship of cryptographic hashes of all the registry proofs generated in Safe Creative. The hash of the XML is then incorporated into the blockchain.

Instead of containing the works or the information of the registrations and their rights holders, it contains the digital fingerprints of the same. In this way, if the digital fingerprint of the registered file matches the one included in the audit file, it guarantees that it is the same.

This process allows for the detection of any modification in a registration proof or in the audit XML itself.

This information shows:

1. The cryptographic hashes of the registered works and inscriptions.
2. A link to the audit XML file along with its hash.
3. A link to consult the transaction in the blockchain.
