To improve the efficiency of quantum communication based on W states, a new scheme about Quantum Information Splitting (QIS) based on W states was proposed. Local operation was used to encode the classic information into the qubit by dealer in this scheme. The nonorthogonal state particles were inserted to detect eavesdropping in the distribution of qubit. To recover the secret, participants only needed to perform three-particle projective measurements. One W state can transmit two bits of classical information between the participants. Moreover, the scheme can resist some attacks like intercept-and-measure attack, intercept-and-resend attack and entangled ancillary particles attack to make sure of its security. The scheme has good efficiency with theoretical quantum efficiency of 67%.
