TIME STAMPING OF DATA IN AN OFFLINE NODE

摘要

The present invention concerns a method for validating timestamps issued by a first node in a communications network, when the first node goes offline. A platform detects (410) disconnection of the first node and triggers a selected second node of the communications network to acquire counter information. When the first node reconnects (421) to the communications network, counter information is retrieved (423; 424; 425; 426) from the second node and timestamped data is received (422) from the first node. The local timestamp information and the counter information are compared to validate or not the local timestamp information. If the local timestamp information is validated, the data can be added to a distributed database such as a Blockchain.
