D.O.C is the more secure platform
How we are taking advantage from
the blockchain technology
Security - Trust - Privacy - Cost saving
the D.O.C platform of services is managed via a blockchain architecture
The D.O.C platform associates tamper-evident digital signatures to a distributed documents storage in a way that is cryptographically secure, privacy respecting, and machine verified.
The useful part is that once a signature hash is stored it cannot be changed or deleted.
This gives you two things:
1) The hash itself identify the file from which it was computed.
2) The fact that your hash is in the blockchain gives you a point in time when the operation was done.
In the future you can say: I’ve signed this document at this date and time, here is the transaction in the blockchain which contains the hash. Now a person can take your file and compute the hash again and verify that it matches the one stored in the blockchain.
