Abstract EN
We propose a new watermarking method based on quantization index modulation.
A concept of initial data loss is introduced in order to increase capacity of the watermarking channel under high intensity additive white Gaussian noise.
According to the concept some samples in predefined positions are ignored even though this produces errors in the initial stage of watermark embedding.
The proposed method also exploits a new form of distribution of quantized samples where samples that interpret “0” and “1” have differently shaped probability density functions.
Compared to well-known watermarking schemes, this provides an increase of capacity under noise attack and introduces a distinctive feature.
Two criteria are proposed that express the feature numerically.
The criteria are utilized by a procedure for estimation of a gain factor after possible gain attack.
Several state-of-the-art quantization-based watermarking methods were used for comparison on a set of natural grayscale images.
The superiority of the proposed method has been confirmed for different types of popular attacks.
