Operation Log Classification for Data Integrity

The patent segments operation logs into two distinct categories: chronologically fixed logs (recorded in chronological order with reliable timestamps) and chronologically unfixed logs (logs that may not reflect true chronological order due to collection issues). This segmentation allows the system to maintain high quantity of collected logs while identifying and handling unreliable logs separately, thus resolving the contradiction between quantity and reliability.

The patent applies preliminary action by recording the collection timing of operation logs from each client terminal before proceeding with log analysis. This preliminary timestamp recording enables the server to later determine whether logs were collected in proper chronological order, making it easier to detect reliability issues without adding complex verification mechanisms during the log collection process itself.

The patent implements partial action by verifying chronological accuracy only for logs that are suspected to be unreliable (chronologically unfixed logs), rather than verifying every single log entry. The server uses the recorded collection timing to identify logs that may not be in chronological order and focuses verification efforts on these specific cases, thereby maintaining reliable assessment without excessive processing time for all logs.
