Abstract
The existing blockchain data covert transmission scheme is faced with the problems of poor concealment, small channel capacity and low efficiency. This paper designs a new model for separating the data embedding mechanism from the transaction filtering mechanism, and proposes a new filtering algorithm based on the address dynamic label. In this scheme, the HMAC algorithm is used to construct the special address label, so that the receiving party can effectively screen the special transaction carrying the concealed information from the massive data in the blockchain ledger, and realize the concealed data transmission in the open blockchain scenario. Simulation results show that the proposed scheme can realize the hidden transmission of data in the real bitcoin network. The concealment and efficiency of the scheme are better than those of the traditional scheme.
