Secret sharing is a cryptography algorithm. This technique divides secret data into multiple parts, giving each participant its own unique part. To reconstruct secret some or all parts of secret are needed. In order to reconstruct secret, if condition is that all participant is mandatory it becomes impractical due to any reason. Therefore threshold based scheme is used where any k of the participant is sufficient to reconstruct the original secret. The proposed secret sharing scheme use audio data to create shares of secret data. As audio data is large in size, to provide protection using encryption technique it becomes time consuming.
