What is a timestamp?

UDIAR platform allows users to protect their works by using timestamps and distributed blockchain systems. 

What is a timestamp? A timestamp is a sequence of characters indicating the date and time at which a certain event was registered in a system. No one, even the owner of the document, can change the information of the recorded timestamp. The easiest way to prove authorship is to prove priority in time, that is why timestamps are so important in the field of copyright documentation systems.

Timestamping service is protected by digital signature. A digital fingerprint or hash-code is a string of digits that uniquely identify a file. Like human fingerprints, digital fingerprints can be used to identify an object. And it is impossible that two different files share the same digital signature.

UDIAR use timestamping service which is compliant with the eIDAS regulation and included in the European Trusted List.
