The intermediate signal may include a pseudo-random key signal so as to obscure the encoding and require knowledge of a corresponding key at the decoder to extract the auxiliary data from the encoded content. In some embodiments, calibration data is encoded in the content signal with the ...
In 2020, Dutch e-commerce security platform Sansec published research which showed that threat actors had embedded skimming malware inside Scalable Vector Graphics (SVG) on e-commerce checkout pages. The attacks involved a concealed malicious payload inside SVG images and a decoder hidden separately o...
In the first unit, they decomposed the image to be watermarked in to four dimensional modified DWT coefficients, by adding pseudo-random codes at the high and middle frequency bands of the DWT of an image. In the second unit, a key has been generated from LHLH frequency bands of the 4-...
We train end-to-end a pair of encoder and decoder Convolutional Neural Networks (CNNs) for creating the hybrid image from pair of input images, and recovering the payload image from input hybrid image –c.f.Fig.1for architecture details. Here, we make use of observation that CNN layers le...

By introducing the Y channel information and a novel structural loss to restrain the training of decoder and encoder networks, the encoder can effectively embed the gray-scale secret image into the Y channel of the cover image, and the decoder can directly obtain the original secret information ...
% tif; the jpg format uses compression and the decoder will not return the % correct MSG if the user tries to save the encoded image in this % format. % Any character from a common keyboard can be encoded, including the % shifted characters and numb...
Eventually, the image transmitter utilizes the ‘Reveal Network’, which can be considered the decoder. Neither the cover nor the hidden images were sent to it. The hidden data was revealed after the decoder removes the ‘Cover Image’. During the network training phase, a small rate of ...

Consequently, to successfully decode the auxiliary data, the decoder must have successfully decoded a previous portion. In essence, decoding instructions are sent "on the fly" in such embodiments. In some embodiments, the auxiliary data is changed in temporally adjoining portions of the content ...
