Imagine the following scenario:
Ana identified the ideal opportunity: a bright, well-located 3-bedroom apartment with an agreed price of €220,000. After some negotiation, everything was aligned with the seller - Bob. They both signed a promissory contract of sale and everything seemed settled.
However, on the day of the deed, Bob showed up with a new version of the contract. The content was practically identical - except for one small but devastating detail: the sale price was now €250,000.

According to him, that was always the agreed amount. And since the document was printed, signed, with the same layout and structure, there was no easy way to prove which version was truth. Ana was left homeless and with a legal problem ahead of her.
The problem of changeable information
This scenario, unfortunately, is not fictional. Every day, contracts, certificates, medical records, or financial reports are digitally tampered with, shared via email, USB drives, or even in printed form, without any reliable way to validate their authenticity.
And when it comes to these types of documents, a subtle change — a number, a clause, a date — is enough to completely alter the meaning of the document and, with it, shift rights, obligations, and even legal consequences.
