Many organizations today are seeking to improve security by implementing multi-factor authentication, the secret sharing is the best way used to share a secret among a group of participants. In real world, there are many applications that require a group of participants to share a secret such as launching a nuclear missile, opening a bank vault, authenticating an electronic fund transaction, and others. The simplest way to share a secret among a group of n participants is dividing the secret into n pieces, with each participant holding one piece, in such a way that knowledge of any k (k ≤ n) or more pieces make the secret easily computable. Knowledge of any k − 1 or fewer pieces leaves the secret completely undetermined. We will show here more than one scheme to share a secret among a group of participants and how we can reconstruct the secret again.
