>From today's headlines:

Unredacted TSA Manual Leaked Online
Aviation Security Agency Used Redaction Method Easily Reversed in Adobe
Acrobat; Screening Procedures Detailed

TSA is obviously headline material, but this isn't just a government
issue. Many companies use Acrobat to redact commercially sensitive or
confidential information (pricing, algorithms, Protected Health
Information, etc.) before sending out a document.

As someone at TSA learned today, just adding a black box over the
sensitive text in Acrobat isn't enough to protect the document.
