A scheme was presented for hiding bits in Bell states, secured even when the sharers, Alice and Bob, were allowed to carry out local quantum operations and classical communication. It was proved that Alice and Bob could gain an exponentially small information about hidden bit in the number of qubits in each share. A low-entanglement method was indicated for the preparation of the shared quantum states. Results showed that secret shares could be created on a small expenditure of quantum entanglement.
