一种基于区块链信息映射的无载体隐写方法
A coverless information steganographic method based on blockchain information mapping
摘要
Abstract
Aiming at the problems of high cost and loss of transaction unlinked information in blockchain steganographic communication,a coverless steganography method based on blockchain information mapping was proposed.First,the block information in virtual currency was preprocessed.The parsed data was analyzed,and suitable information was selected as the secret information carrier according to the data's attributes.Then,parity mapping rules were constructed for the extracted data to map the secret information into the block information.Finally,the receiver extracted the desired secret message from different blockchain scenarios based on the accompanying information.Experiment results show that the capacity of a single secret message transmission can be effectively increased.Meanwhile,the use of coverless technology does not require initiating a transaction on the chain,which can effectively save the cost incurred by constructing a transaction.The mapping of secret messages in different blockchain scenarios can be implemented,which improves the expandability of blockchain covert communication.关键词
