With the advent of Internet-of-Things, sensor data streams are widespread and thus a promising target for network steganography including covert channels. Therefore, we present an approach where sender receiver first build archive values that occur in stream over time interval, then encode bits secret message via belonging to class seen or not. If value’s category does not match required bit value, it is adapted switch its category. The chosen value minimizes distance original improve stealthiness. Furthermore, application scenario analysis channel’s detectability, particular how detectability steganographic bandwidth can be traded against each other. We have tested proposed detec-tion metrics simulation experiments.
