Abstract: Provided is a method for managing a sensitive data in which each authentication factor in a set of authentication factors has been uniquely assigned a group containing several secret shares generated by using a secret sharing scheme. It includes verifying via an authentication factor to generate a score reflecting a level of confidence of the verification, wherein a subset of the secret share(s) assigned to the authentication factor is added to a collection, the subset comprising a number of secret share(s) depending on both said score and a predefined parameter associated with the authentication factor. Sensitive data is built from the secret shares of the collection by applying a predefined algorithm associated with the secret sharing scheme.
