Abstract
An exemplary embodiment of the present disclosure illustrates a sensitive data discrimination method executed in a data loss prevention system to determine whether a file has the least one sensitive data during a file generation proceeding. Steps of the sensitive data discrimination method are illustrated as follows. Multiple characters inputted via a keyboard are recorded. The recorded characters are trimmed to generate a trimmed data. The trimmed data and at least one predefined term related to the at least one sensitive data are compared, to determine whether the trimmed data has the at least one sensitive data.
