NETLOCK timestamping services

After the implementation of the serving system, NETLOCK is able to attach authentic time stamps to data in any electronic form in the framework of timestamping services.

In course of Qualified Time Stamping Services, NETLOCK issues time stamps for its customers in harmony with the RFC 3161 Internet X.509 Public Key Infrastructure Timestamp Protocol.

Due to the nature of the technology, the independent timestamping service provider works exclusively with a hash of the document to be sealed, from which the original document cannot be restored either partly or totally during the timestamping process. This ensures that the service provider cannot have access to the contents of the document.

During timestamping, the independent timestamping service provider assigns reference time, calculated on the basis of times from 3 independent time sources (generally 2 of them are highly reliable atomic watches), to the submitted hash, then authenticates it by its own electronic signature and returns to the user.

The potential users of timestamping services are as follows: brokerage firms, banks, insurance companies, accounting houses, on-line commercial houses, electronic market places, archiving companies, enterprises dealing with electronic invoicing.

The timestamp proves satisfactorily that the timestamped document surely existed already in its current form at the time indicated in the timestamp.


On the basis of the relevant provisions of the guiding eIDAS Regulation 910/2014/EU and Act CCXXII (2015), documents in any electronic form, supplied with advanced, as well as qualified time stamps, prove with the legal consequences of committing to writing and with conclusive evidence, respectively, that the given document existed already in the moment of time stamping and its content has not been changed since then.
