01
You compute the hash
On your own machine, you generate the cryptographic fingerprint of your file: your algorithm, plan or document.
Product · Secrets and assets
Prove it existed, without revealing what it is
Protect your know-how, your algorithms, your business plans and your documentation as a trade secret: certify their existence with a certain date without the content ever leaving your environment, under a Zero-Knowledge protocol.
Hash-only certification · Certain date · Full confidentiality · eIDAS + blockchain
How it works
You certify the fingerprint, not the content
The key is the hash: a unique digital fingerprint of your file that proves its existence and integrity without exposing it.
02
You certify only the hash
You send only that fingerprint to Safe Creative, which seals it with a certain date. The content is not uploaded.
03
The day you need it
You present the original and prove it matches the certified fingerprint: proof that it existed and has not been altered.
What you can protect
What your company owns and doesn't know it owns
A company's value increasingly lies in its intangibles. These are the assets worth locking down.

Zero-Knowledge: not even we see your secret
When you certify only the hash, your confidential information never leaves your environment: Safe Creative records the fingerprint, not the content. It is maximum confidentiality, included in the Business plan for registering assets and secrets.
- The file is not uploaded: its fingerprint is certified.
- Proof of existence and integrity on a certain date.
- Full confidentiality under a Zero-Knowledge protocol.

Trade secret · Law 1/2019
A reasonable measure to protect your secret
The Spanish Trade Secrets Law 1/2019 protects your confidential information as long as it has value because it is secret and you adopt reasonable measures to keep it that way. Certifying its existence with a certain date documents that diligence and proves what information you held and since when.
- Establishes the priority of your know-how over third parties.
- Documents the protection measures the law requires.
- Strengthens your position in leaks or disputes with employees or partners.
Trade secret vs. patent vs. copyright
Trade secret: protects know-how while it is kept secret. It is not published.
Patent: protects an invention, but requires publishing it. It is a different right.
Copyright: protects the finished work, not the idea or the method.

Frequently asked questions
Questions about secrets and assets
Do I have to upload my confidential information?
No. You can certify only the hash (the fingerprint) of your file, computed on your machine. Safe Creative records that fingerprint with a certain date, but the content never leaves your environment. It is the essence of the Zero-Knowledge protocol.
How do I later prove the secret is mine?
The day you need it, you present the original file. If its hash matches the certified fingerprint, it is proven that that exact content existed on the date of registration and has not been altered.
Is this the same as a patent?
No. It is proof of existence and certain date that helps protect your information as a trade secret, which is a right distinct from a patent. A patent protects inventions but requires publishing them; a trade secret protects know-how while it is kept confidential. It does not replace advice from an industrial property agent.
How does it fit with the Trade Secrets Law?
Law 1/2019 protects secret information if you adopt reasonable measures to keep it secret. Certifying its existence with a certain date documents that diligence and proves what information you held and since when, strengthening your position in a leak or dispute.
Which plan is it available in?
Registering assets and secrets under a Zero-Knowledge protocol is included in the Business plan and above. You can also integrate it into your systems via the API.
Can I automate it in my systems?
Yes. Through the API you can seal the fingerprint of your files, backups or releases from your own workflows, sending only the hash. It is a professional route with terms by agreement.
Your most valuable asset, protected
Leave a record of what your company knows, without revealing it, with the confidentiality of the Zero-Knowledge protocol.
Safe Creative, the largest online intellectual property registry and trusted third party, operating since 2007. Certification proves the existence and integrity of a file on a certain date by means of its cryptographic fingerprint and a qualified time stamp (EU Regulation 910/2014, eIDAS), with a blockchain audit, without the content being stored when the hash-only (Zero-Knowledge) mode is chosen. It does not by itself amount to a patent nor replace advice from an industrial property agent. Effective protection of a trade secret under Law 1/2019 depends on the measures adopted by its holder.
