从 PDF 中删除敏感数据

PDF redaction is the process of permanently removing sensitive or confidential information from a document so that it cannot be recovered or viewed. Unlike simple visual masking, true redaction deletes the underlying content, ensuring it is not accessible through copying, searching, or metadata extraction. This capability is essential for regulatory compliance, data protection, and secure document sharing, particularly in industries that handle personal, financial, or legal information.

Several ASP.NET Core PDF components allow you to redact PDFs, including:

• Document Solutions for PDF by MESCIUS provides a .NET API that enables developers to define and apply redaction regions and permanently remove sensitive content from PDFs.
• ImageGear for .NET by Accusoft includes redaction annotations allowing applications to mark and obscure confidential information within documents.
• Syncfusion ASP.NET Core PDF (part of Syncfusion Essential Studio Enterprise) offers redaction support, with APIs to mark and remove sensitive text or images.
