System for method for secured logging of events

A system for secured logging of a second event. The system includes a logging device and a triggering device The triggering device receives an input related to the second event, creates second event message based on received input related to the second event, and receives the first set of data related to first logged event from the logging device. The triggering device further creates a first position-lock data from the first set of data, creates a second append request, and provides the second append request to the logging device. The logging device is configured to verify the second append request. Based on positive verification, the logging device creates a logging device signature over a second log-append-approval, and combines the created logging device signature with the provided second append request to form a second logged event.
