Based on the characteristics of three-particle GHZ state, we propose a novel quantum secure direct communication scheme(QSDC). In the process of security check, both sides of communication detect single particle with the entanglement properties between the particles. The number of possible quantum states has greatly increased and there are more errors when the check particles are attacked. The error rate for eavesdropper is increased with 62.5%. The security of the scheme is improved.
