Embodiment Construction
[0091] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0092] The flowchart of the method of the present invention is as figure 1 As shown, it specifically includes the following steps:
[0093] Step 1, extract the color, texture and shape features of the image in the image library.
[0094] Step 2, use the locality-preserving projection method to reduce the dimensionality of the image features, and after Gaussian normalization, the three types of features are combined into a 49-dimensional feature vector.
[0095] Step 3, use the Paillier homomorphic encryption algorithm to encrypt the rounded features.
[0096] Step 3.1, constructing a Paillier encryption system to generate a public key and a private key, where the parameters p and q used are both 256 bits.
[0097] Step 3.2, integerize the 49-dimensional feature vector;
[0098] In step 3.3, use the Paillier homomorphic encryption algorithm to encryp...
