A Two Fold Approach to Store and Share Secrete Data for Groups in Cloud

Abstract

This paper highlight various disputes related to
confidentiality and security while storing customer’s data on
untrusted cloud. At the current a days Sharing of data and
resource between the cloud users is a important problem.
There is a portion of search being made to find out the
disputes with these cloud service contractors and cloud
security in general. In this paper system recommends a secure
two fold method to share data for dynamic group in the cloud.
Biometrics transaction with computerized organizations of
identifying a person or verifying the identity of a person based
on physiological or interactive characteristics. Visual
cryptography is a top-secret sharing method where a secret
image is encrypted into the shares which independently reveal
no information about the original secret image. As biometric
pattern are deposited in the central database, due to security
threats biometric Pattern may be revised by attacker. If
biometric pattern is reformed authorized user will not be
allowed to access the resource. To contract this issue visual
cryptography schemes can be applied to secure the iris
Pattern. Visual cryptography offers excessive means for
helping such security needs as well as further layer of
authentication. By providing group signature , encryption
techniques and two fold methods, any cloud user can securely
share data with others. This technique rights required
consistency, security, scalability and most importantly
proficiency.
