To achieve watermark synchronization from an image with perspective distortion is a
challenge. This paper proposes a screen-cam robust and blind watermarking scheme for tile …

The screen-cam process, which is taking pictures of the content displayed on a screen with
mobile phones or cameras, is one of the main ways that image information is leaked …

This paper proposes a joint encryption and screen-cam robust watermarking scheme. This
method combines the advantages of smartphone, encryption and watermarking …

This article proposes a blind discrete wavelet transform-discrete cosine transform (DWT-
DCT) composite watermarking scheme that is robust against print and scan distortions. First …

It is a challenging work to design a robust localized color image watermarking scheme
against desynchronization attacks. There are two main drawbacks indwelled in current …

Security checking can be improved by watermarking identity (ID) images printed on smart
cards plastic supports. The major challenge is resistance to attacks: printing the images on …
