Research On Document Information Hiding Technology Based On Big Data

With the rapid development of network,communication technology,the computer network pays more and more attention in information,which also emphasize the higher and higher importance of information security technology.Along with more and more information transmitted in the internet,a variety of attacks against the transmission of confidential information also increase rapidly.Military secrets,business information,financial accounts and other information has a very high demand on the safety of the network transmission.The traditional approach is to use encryption technology,changing the transmission of clear text to cipher text generated by different encryption algorithm.Compared with the traditional encryption method,the information hiding technology used in this paper is to hide the confidential information in the transmission carrier,so that the attacker ignores the existence of confidential information,which is the most essential difference from the traditional encryption algorithm.In this paper,a new method of information hiding based on the Office Open XML file format is proposed,based on AES encryption algorithm.The method embeds information into the target document by replacing or constructing identifier attribute value according to the document structure characteristic,which achieves the purpose of information hiding.Furthermore,in order to adapt the traditional information hiding technology to the trend of Big Data,this paper combines the distributed processing technology of Big Data with information hiding technology to design an information hiding system corresponding to Big Data distributed processing method.The experimental results show that the designed information hiding system has good robustness,information hiding capacity and concealment.From the results of resource consumption,this system's processing speed is satisfactory.At the final part of this essay,the prospect of future research direction is presented.
