In plain words
Timeshifter is a steganography system that hides data within network packet timing by encoding information as intervals between packets. Users can adjust parameters including a threshold for distinguishing zero bits and a time delay for generating one bits. The software transmits and receives hidden messages through packet timing variations, making data transmission less conspicuous by embedding it in what appears to be ordinary network traffic.

From the sources
We created a system in order to transmit and receive data by modifying the time intervals between packets. Steganography provides a way to hide data in plain sight, in this case as time intervals of packets. As the data isn’t immediately obvious it is less likely to arouse suspicion. There are two variables which can be adjusted as parameters of the program. The first being the threshold, that intervals between packets below or equal to, will be classed as a zero bit. Another variable represents the ammount of time delay that is added between two packets, to generate a one bit. By making these value lower, transmission speed is increased and the noticability of data transmission will…from anfractuosity.com
