A scheme is proposed for quantum information splitting (QIS) of a product state of an arbitrary single-qubit state with three-qubit GHZ states. The scheme focuses on a product state of an arbitrary single-qubit state, and the original state can be reconstructed only if the receivers cooperate with each other. Every receiver has the same authority for getting the sender’s secret, and the receivers have the same probability to get the original secret, the probability to gain |φa| is obtained as 2|βb|2, the probability to gain |φb| is obtained as 2|βa|2.
