The user device encrypts input vectors using a client's public key to keep client information private. The server computer homomorphically computes a distance between the encrypted input vector and vectors stored in the k-nearest neighbor model. The server computer then engages in a minimization process which results in the user device receiving classification vectors corresponding to the k-nearest neighbors."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure computer evaluation of k-nearest neighbor models","description":"A user device and one or more server computers securely evaluate a k-nearest neighbor model, with reasonable computation speed and bandwidth utilization, using a combination of techniques.
