The system generates a challenge. The system transmits to a client computing system an encrypted challenge generated using the challenge and a public key of an asymmetric key pair to a client computing system. The system fragments a private key of the asymmetric key pair into a first, second and third private key fragments. The system generates a first partially decrypted challenge using the first private key fragment and the encrypted challenge. The system receives a second and a third partially decrypted challenges from the client computing system. The system generates a decrypted challenge using the first, second and third partially decrypted challenges. The system compares the decrypted challenge and the challenge for identity verification."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Identity confirmation using private keys","description":"Systems and methods for identify confirmation and transaction security are described.
