Embodiment Construction
[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0026] The spectral clustering algorithm based on differential privacy protection provided by the present invention is based on the differential privacy model, uses the cumulative distribution function to generate random noise satisfying the Laplace distribution, and adds the noise to the sample similarity calculated by the spectral clustering algorithm In the function of , the weight value between sample individuals is disturbed, and the information hiding among sample individuals is realized to achieve the purpose of privacy protection.
