We demonstrate the possibility of controlling the success probability of a
secret sharing protocol using a quantum cloning circuit. The cloning circuit is
used to clone the qubits containing the encoded information and {\em en route}
to the intended receipients. The success probability of the protocol depends on
the cloning parameters used to clone the qubits. We also establish a relation
between the concurrence of initially prepared state, entanglement of the mixed
state received by the receivers after cloning scheme and the cloning parameters
of cloning machine.Comment: This is a modified version of the previous work
