The information leakage problem often exists in bidirectional quantum secure direct communication or quantum dialogue.In this work,we find that this problem also exists in the one-way quantum secure communication protocol[Chin.Phys.Lett.32(2015) 050301].Specifically,the first bit of every four-bit message block is leaked out without awareness.A way to improve the information leakage problem is given.
