KeeeX Technology

KeeeX is a French pioneer in securing and certifying digital files using the benefits of the blockchain. It holds two EU/US patents. The patent is based on the embarkation of a trust passport for all file formats (+250 formats). Photo Proof Pro integrates KeeeX technology to secure forms, photos, videos as soon as they are taken, making the data collected indisputable as to their integrity, origins, date and place of taking.


With KeeeX, the hash (which protects the integrity of the file) is embedded in the metadata. The data can be stored on your environment and auditable without dependency on our infrastructure.

Reminder of the self-supporting evidence

Each photo, video, data carries a digital passport invisible to the naked eye integrating proof of integrity, anteriority, date, source (user’s signature) and geolocation.

How to verify a keeexed file ?

All keeexed file embedded an invisible digital passeport that can be control and read by differents ways

Free Web Portal

All Keeexed files can be quickly verify on our free web portal:


Component Integration

Our verification modules can be integrated into your own system. The first way is to give you the same framework that we used on our verification devices. The second way is to generate your own design module on our component. Below is an example of our iframe component.


Files are processed locally during verification. No data will be transmitted to our servers.
As we like to say: “Don’t trust, verify” ! Do not hesitate to activate the aeroplane mode before checking your files 😉


Is the application usable even in poor conditions?

Yes, perfectly! Once connected, media protection is done locally on the phone. The timestamp and the sending of the information to your server are done once the Internet connection is restored.

How long does it take to deploy?

The deployment is very fast. The generic Collect and Prove mobile application is available on the Android and Apple stores. Creating a custom scenario takes a few hours. Setting up to receive the elements on your server is also very quick, just open an API route (we can also set up a proxy) or provide a storage server (sftp, object storage).

Why you rather than a competitor?

For various reasons! We like to say that you will like us because you can leave us whenever you want. KeeeX is not a trusted third party. By embedding evidence directly into photos and videos, your files remain verifiable for free, with no time limit, even without KeeeX. Your photos can be reused in your business processes or help train image recognition algorithms.

What is the legal validity of your solution ?

Collect and Prove is 100% eIDAS compliant. We embed integrity, date and digital signature evidence in your files. By opting for qualified time stamping, you benefit from a presumption of validity by default. Because keeexed files carry their own evidence record, our clients typically see a reduction in disputes by providing them to the other party.

What elements can I include in a scenario?

You can include in a scenario your logo, titles, text fields, drop-down lists, date fields, photo or video shots, manual signatures, mandatory fields, pre-filled fields.

Can I use it in different countries?

Yes, our mobile application Collect and Prove by KeeeX is now used in more than 50 countries. It is already available in different languages: French, English, Spanish, Portuguese. Other languages can be added on demand.
