Turbo coding for sample-level watermarking in the DCT domain
Coding at the sample level in still image watermarking takes advantage of avoiding a non-optimum initial diversity stage, used in many watermarking systems for tailoring Gaussian ...

Effective Channel Coding for DCT Watermarks
We describe effective channel coding strategies which can be used in conjunction with linear programming optimization techniques for the embedding of robust perceptually adaptive ...

Compressed-domain temporal adaptation-resilient watermarking for H.264 video authentication
In this paper we present a DCT domain watermarking approach for H.264/AVC video coding standard. This scheme is resilient to compressed-domain temporal adaptation. A cryptographic...

Hierarchical watermarking depending on local constraints
In this paper we propose a new watermarking technique where the watermark is embedded according to two keys. The first key is used to embed a code bit in a block of pixels. The se...
