Privacy for cloud computing has become an important issue in recent years. In this paper, we propose a threshold-based model for privacy protection in cloud computing with a particular (n +1, t +1) secret sharing scheme which is bases on the matrix and vector. We show how our (n +1, t +1) secret sharing scheme can be applied to protect privacy. First, we assign each row of the matrix as a key of vector. Next, we make use of the linear correlation and linear independence of the vector to…
