Abstract
The present disclosure relates to a method for providing a self-sovereign identity cloud service to a user. The method includes signing, on a user device of the user, an instruction to store self-sovereign identity data of the user based on a user private key of a user asymmetric key pair. The method further includes sending the signed instruction and the self-sovereign identity data from the user device to a cloud server. The method further includes verifying, in a trusted execution environment of the cloud server, the signed instruction based on a user public key of the user asymmetric key pair. The method further includes, if the signed instruction is approved, storing the self-sovereign identity data in the trusted execution environment.
