You are handling a document containing mixed-sensitivity content before using it with Claude.

Under the objective Apply data, privacy sensitivity, regulatory policies, and privacy considerations, responsible data management follows a strict, sequential security lifecycle when handling enterprise data for AI tasks.

Before any redaction, sanitization, or masking can occur, the user must first classify the document’s data assets and systematically identify which elements constitute sensitive data (Option B)—such as Personally Identifiable Information (PII), Protected Health Information (PHI), or confidential corporate financial figures. Without establishing data classification boundaries, redaction (Option A) becomes incomplete and error-prone. Only after identifying and classifying sensitive fields can one properly redact them (Option A), conduct a quality assurance/peer review (Option D), and ultimately submit the sanitized payload to Claude (Option C).
