Approaches in Steganography

1
Approaches in Steganography

• Classic Prisoner Communication Problem
• Passive Warden
• Attempts to detect only
• Active
• Attempts to corrupt embedded data (success may
  help detection)

2
Approaches in Steganography

• End-user needs reliable steganalysis tools
• Low false positives/false alarms
• Current techniques dont have the reliability
• Detection not enough
• Wants to extract and exploit embedded data (an
  intractable problem?)

Approaches in Steganography

• Standard test databases commonly available would
  be useful
• Multimedia clean/stego data
• Tiered steganalysis approach useful
• Anomaly based tools
• Targeted algorithms
• Sharing of research important
• Authenticated? Open? listserv, email group
