This paper describes a multi-secret steganographic system for the Internet-of-Things. It uses two user-friendly sensors for data input: thumb joystick and touch sensor. These devices are not only easy to use, but also allow hidden data entry. The system conceals multiple messages into the same container, but with different algorithms. The embedding is realized with two methods of video steganography that work on mp4 files, namely, videostego and metastego. These methods were chosen because of their low complexity so that they may operate smoothly in environments with limited resources. It is possible to replace the suggested sensors with others that offer similar functionality.

“…Subliminal channels are a great way of covert communication in an insecure environment. They find application in, for example, steganography [16], to hide secret data without suspicion. Normally, visual cryptography is used for image protection [17], and when saving computing resources is important [18,19].…”

This paper describes three methods of creating a subliminal channel in visual cryptography that are defined for a (2,2) sharing scheme. They work by hiding additional covert information besides the original encrypted image. The first channel is revealed when the user folds the share along the specific axis. The second channel encodes subpixels on the basis of the encrypted message bits. It is designed to hide a wide range of data types. The third channel may be applied to a single share or multiple shares and is revealed when the proper parts of the shares are stacked. Fold and overlapping algorithms are adequate for printed shares, but the encryption method is only suitable for digital shares. The capacity of these methods ranges from half of the image size to the whole image size. The presented algorithms work on black-and-white images but are expandable to color visual cryptography. They may find applications in steganography and other data-hiding techniques. The created subliminal channels do not interfere with regular images that may still be revealed by stacking the shares. In short, this article introduces subliminal channels in visual cryptography, presents three algorithms for both binary and colorful images, shows examples of use with the results obtained, and discusses features of each method.

“…In this paper have been defined new steganographic techniques for information hiding, which depend on the carrier. In traditional steganographic solutions secret hiding is not dependent on the content or features of container [1], [2]. Most approaches modify parameters in spatial or frequency domains, and not consider local carrier parameters [3].…”

In this paper we'll describe new techniques of information hiding in visual containers. Presented methods will be connected with the carrier features, so secret distribution will be dependent from the content and pixel values. In traditional secret hiding solutions the way of information distribution is not dependent on the content or container's features. Such approaches simply modify spatial or frequency parameters, without consideration of local carrier parameters. Such parameters can also determine the way of secret hiding and allow to split information over container in different manner, especially when we consider containers with different graphical features.
