To determine the risk, the system could read metadata identifying a document’s sensitivity and the sections containing protected information. For instance, a document containing financial records, personal information, or national security material could receive stronger protection than content classified for public access. The proposed system replaces a fixed biometric reauthentication interval with a schedule that responds to what is being displayed and where it is being viewed. The application suggests that a high-risk situation could trigger a check every 30 seconds or every few minutes, while a low-risk setting might be checked hourly.
