In this paper, only Bell states are employed and needed to be identified to realize the multiparty secret sharing of quantum information, where the secret is an arbitrary unknown quantum state in a qubit. In our multiparty quantum information secret sharing (QISS) scheme, no subset of all the quantum information receivers is sufficient to reconstruct the unknown state in a qubit but the entire is. The present multiparty QISS scheme is more feasible with present-day technique.
