Query: Protection of SVM Model with Secret Key from Unauthorized Access   In this paper, we propose a block-wise image transformation method with a
secret key for support vector machine (SVM) models. Models trained by using
transformed images offer a poor performance to unauthorized users without a
key, while they can offer a high performance to authorized users with a key.
The proposed method is demonstrated to be robust enough against unauthorized
access even under the use of kernel functions in a facial recognition
experiment.
