ABSTRACT:
A method processes an input image securely. An input image I is acquired in a client. A set of m random images, H1, . . . , Hm, and a coefficient vector, a=[a1, . . . , am], are generated such that the input image I is I=Σi=1mαiHj. The set of the random images is transferred to a server including a weak classifier. In the server, a set of m convolved random images H′ are determined, such that {H1′=π1(H1*y}i,1m, where * is a convolution operator and π1is a first random pixel permutation. The set of convolved images is transferred to the client. In the client, a set of m permuted images I′ is determined, such that I′=π2(Σi=1mαiH1′), where π2is a second random pixel permutation. The set of permuted image is transferred to the server. In the server, a test image Ī such that Ī=αƒ(I′) is determined and a true signal is returned to the client if there exists a pixel q in the test image such that Ī(q)>0, otherwise return a false signal is returned to the client to indicate whether or not the input image contains an object.
