Secured Covert Communication Through Blockchain Technology

Blockchain is a public open ledger that provides data integrity in a distributed manner. It is the underlying technology of cryptocurrencies and an increasing number of related applications, such as smart contracts. Secure covert communication can be implemented as a combination of cryptography and steganography. Cryptography ensures that the communicated message stays private, while steganography is used to hide the fact that the encrypted communication provide. The key idea of this investigation is to automate the covert communication on blockchain technology. Covert communication channels are designed to protect the relationship between the transmitter and the receiver by hiding the fact that secret communication is taking place. The proposed scheme provides higher embedding capacities compared to the existing schemes. The motivation behind the development of this research work is an attempt which create a practical application that will help in improving the emerging use of IT technologies in a developing country like India today.
