Second, Inline protocols which employ a trusted third party (TTP), which acts as a delivery channel. Both parties send their items to the TTP which checks for their integrity, ensures the validity and fairness of the exchange, and forwards the items to the intended receivers.Third, online protocol, similar to inline protocol, but sender can communicate to receiver directly. After that, TTP manages all extra effort to provide the Integrity, validity, and fairness of the exchange, and forwards the message to receiver. TTP also sends to sender, a receipt of proof that receiver is accepted that message.
