摘要
Provided herein are system, devices and methods for applying Multi-Party Computation (MPC) to authenticate a user accessing a secure resource using a plurality of computing nodes. The computing nodes, each receiving a respective one of a plurality of encrypted shares created using a plurality of keys to encrypt private data captured by a client device used by the user accessing the secure resource, engage in a secure MPC to compare between the encrypted shares and reference encrypted private data copies also encrypted using the plurality of keys without decrypting the private data since the keys are not available to the computing nodes. The computing nodes compute a match score based on the comparison and transmit it to a controller of the secure resource configured to grant or deny the client device access to the secure resource based on the match score.
