Research On Information Hiding Method Of Instant Communication

People often encounter information leakage when they use some information transmission tools like instant communication software.It is urgent to ensure the safe transmission of network information.Information hiding technology has a good effect in solving the above problems.However,according to the survey,the advanced information hiding technology based on text generation has not been applied to instant communication.In order to further ensure the safe transmission of secret information in instant communication software,the information hiding system of instant communication is constructed by combining the two methods.Based on the improved information hiding and extraction algorithm,the system can generate multiple rounds of the encrypted dialogue texts according to the secret information.It is suitable for instant communication software and has a certain degree of academic value and application value.The information hiding system of instant communication includes text generation model and secret information hiding and extracting model.For text generation model,the Word2 vec tool is used to convert the natural texts after words segmentation into word vectors.Then,the word vectors are inputted into the multi round dialogue generation model which is built by seq2 seq framework.In this model,Bi-LSTM is used to capture the semantics of input texts from both positive and negative directions,and attention mechanism is used to give high weight to keywords.These methods can improve the relevance of generated dialogue texts.In addition,the system introduces beam search algorithm.This method reduce the probability of local optimal solution and improves the diversity of generated dialogue texts.Moreover,preprocess the shopping conversation dataset and discard the content that affects the dialogue generation.After that,the model can generate high quality texts of multi round dialogue in the context of online shopping.For the model of secret information hiding and extracting,the model of seq2 seq multi round dialogue generation and arithmetic coding are combined by improving algorithm for generating long text information hiding based on arithmetic coding.In the process of information hiding,the concentric disks are constructed by using the alternative words of the multi round dialogue generation model.And then,based on the segmented bit stream of secret information,the multiple rounds of encrypted dialogue texts are generated.In the process of information extraction,the multi round conversations are inputted into the system,the concentric disk is restored,and the secret information is extracted according to the encrypted words.The contrast experimental results show that,the encrypted dialogue texts generated by the information hiding system of instant communication has lower perplexity and higher hiding capacity.In conclusion,the encrypted texts have high readability,and the system has strong concealment.The system uses less conversational rounds to hide secret information,and the probability of attracting attention is low.Therefore,the system is a safe information hiding system.
