Current research in watermarking

Theoretical issues under investigation:

• optimal watermark encoding for different applications (Turbo and LDPC codes, TCM and multilevel coding with precoding)
• watermarking as communications with side information:

host interference cancellation

channel state estimation and optimal decoding

synchronization

• watermarking resistant against copy attack
• error resilient coding
• capacity-security analysis of data hiding technologies
• blind stochastic detection of hidden data 
• perceptual watermark embedding and relationship to stochastic image models
• robust watermark extraction and detection
• watermarking attacks
• benchmarking.

Data hiding applications:

robust digital watermarking (Berkut 1.0)

hybrid media authentication and tamper proofing (Berkut 2.0)

document security

secure media delivery (both digital and analogue)

high-capacity data hiding (both digital and analogue)

steganography and steganalysis (StegoWall)

network security (StegoWall)

stegoviruses dtection (StegoWall)
