Text Steganography Based on Parallel Encryption Using Cover Text (PECT)

This paper presents a self-checking text steganography which could be used efficiently where large data is involved in various IoT applications. The space complexity of its cover text is one-fourth of its message size which is very less as compared to other techniques. The cover text of this method is generated from the private message itself. Later it is used to check the correctness of the data on receiver side. This helps to reduce the time overhead in case of corruption of any part of the data. Thus, the security and trust issues of IoT are easily handled even on high traffic channels.
