Abstract: Systems, methods, and software can be used to provide security assurance information. In some aspects, a certificate request for a client process on a mobile device is received. A security assurance character for the client process is determined. Whether to grant the certificate request is determined based on the determined security assurance character. In response to determining to grant the certificate request, a certificate is generated.

Abstract: A computer-implemented method comprises sending, to a first device, a request for a signed certificate, the request for the signed certificate comprising a signed hash of data associated with a user, a corresponding public key of the user, and the data associated with the user; sending, to a second device different from the first device, a request for the signed certificate, the request comprising information to retrieve the signed certificate; and obtaining, from the second device, a signed certificate, the signed certificate comprising the public key of the user, the hash of the data associated with the user, and information indicating a health status of the user, the data associated with the user being absent from the signed certificate.
