“…Another technique called Principal Component Analysis (PCA) could be used by an attacker to estimate the projection vector p as done in (Cao, 2014). PCA identify a smaller number of uncorrelated variables known as principal components from a complex data set.…”

“…Consequently, the robustness of the CAR-STDM and the traditional STDM increases while ∆ increases. (Cao, 2014) proved that an attacker could estimate the projection vector of STDM, for that they proposed an improved method called ISTDM. In this method, the host signal is divided into two mutually orthogonal subspaces with the same dimension.…”

“…(Bas and Hurri, 2006) show that STDM can be attacked successfully using a Blind Source Separation (BSS) technique called Independent Component Analysis (ICA), by estimating the projection vector p of STDM used during the embedding process. (Cao, 2014) proved that an attacker can estimate the projection vector p using another BSS technique called Principal Component Analysis (PCA). Therefore, they proposed an improved method for STDM called ISTDM in order to resist such kind of BSS attack.…”

Spread Transform Dither Modulation (STDM) is a blind watermarking scheme used for its high robustness against re-quantization and random noise attacks. It has been applied mainly on images, speech, and PDF documents. The key of this scheme is the projection vector aiming at spreading the embedded message over a set of cover elements. However, it has been recently shown that such a key vector can be estimated thanks to Blind Source Separation (BSS) techniques, e.g. Principal Component Analysis (PCA) and Independent Component Analysis (ICA). This security breach can be harnessed by an opponent to copy, remove, or modify the embedded watermark. In this position paper, a CAR-STDM (Component Analysis Resistant-STDM) is designed and its application on PDF documents is presented. The security is guaranteed by the use of a cryptographically secure number generator, preventing algebraic approaches (as BSS ones) from finding the key. First experimental results show that the Secure-STDM achieves the security against the aforementioned BSS techniques. It is further shown that CAR-STDM preserves its robustness against AWGN and Salt&Peper attacks, and keeps furthermore its transparency.
