Information hiding is an important method to solve the problem of information security, and LSB algorithm is a common image information hiding method. Based on Logistic chaotic sequence, an improved LSB algorithm is proposed with the XOR operation to complete the encryption of embedded information. The simulation results show that the algorithm has good safety performance and can resist the pollution of salt and pepper noise. It is a kind of practical algorithm.
