Comparing files with user-created data
Due to the limitations of the central repository-based method, the preferred method is to compare two self-generated data sets and what best practices suggest. This type of solution detects file changes by comparing fingerprints to its own previous scans.

This means that the plugin generates the first fingerprints upon installation. Then, when you scan the files again, it will compare the new fingerprints with those from the original scanner. And whenever a file change is recorded, you can configure the plugin to automatically accept that change or to send you an alert.

This method is preferred over the previous one due to the following advantages:

The system adapts to your website (it can validate changes and belize phone number data update fingerprints, allowing for continuous customization).
Reports significantly fewer false positives.
For these reasons, when looking for a File Integrity Monitoring tool or plugin, it is advisable to choose one that relies on auto-generated data.
