Security of secret data is major concern in today's digitized world. It is an important task to preserve the secret data from the probable threats, during the transmission. Various techniques [1,2,3,4,5,6] have been proposed in literature for secure transmission of data but not much work has been done on the secret transmission of images which is one of the difficult task to accomplish. One of the secret sharing schemes [11,7] which are used in literature to share the image transmission side can be applied either by using Blakeley's secret sharing scheme [2]) or Shamir's scheme [1] for sharing a secret. In this paper Shamir's secret sharing scheme is analyzed and implemented on a fingerprint biometric trait. The motivation for secret sharing [1,2] comes from the concept of secure key management. The schemes allow a user to divide portions of a secret among a participants group. Any t or more participants from a participants group of n members can cooperate to regain the original secret while (t-1) or fewer participants cannot reveal anything about the original secret.
