A client sends to the platform data to be classified in encrypted form using a first symmetric key. Similarly, a supplier sends to the platform parameters of a classification model in encrypted form using a second symmetric key. The invention uses a homomorphic cryptosystem defined by a public key and a private key. The platform performs a first transcryption step by deciphering the data to be classified in the homomorphic domain and a second transcryption step by deciphering the model parameters in the homomorphic domain. The classification function is then evaluated in the homomorphic domain for providing a classification result encrypted by said public key."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for secure classification using a transcryption operation","description":"The present invention concerns a method for secure data classification by a computer platform.
