In the field of information security,information hiding is a new technology.The traditional information hiding algorithm can not solve the secret information the robustness and invisibility of contradiction between,put a method based on convolution code and two information hiding algorithm.First,by using convolutional codes,the secret information was encoded,the secret information security was improved,and then the secret information was made a class two scrambling process to enhance the invisibility of secret information,finally the information,s embedding and extraction were carried out by employing LSB algorithm.The experimental results show that this algorithm not only makes the secret information,with good invisibility,and has good noise immunity,anti attack capability,strong robustness,good to solve the information hiding process robustness and invisibility of the contradiction between.
