Abstract: Disclosed is a system for updating a reference time from a decaying rotational period of a pulsar. The system can include: a database (DB) configured to store: coordinates for a pulsar; a recorded rate of rotation (RROR) for the pulsar; a rotational rate of decay (RROD) function for the pulsar; and a recorded reference time for the pulsar. A sensor can be configured to collect electromagnetic pulsar radiation from the pulsar and generate sensor data. A signal processor module can be configured to receive the sensor data, generate an observed rate of rotation (OROR) signal profile, generate a current rate of rotation (CROR) for the pulsar from the OROR signal profile, and update the RROR from the CROR. A time processor module can be configured to receive the RROD function and the CROR, and to solve the RROD function to output a reference time of the pulsar.

Abstract: A system for issuing a certificate to permit access to information, the system including: an identification service to receive dynamic biometric and contextual data regarding an individual located within an area, and to receive at least one of stored identity, biometric, and contextual data for a given individual to provide an identity estimate and a level of certainty indicator of a match based on comparison of the biometric and contextual data regarding the individual to the biometric and contextual data regarding the subscribers; a registration authority to receive the identity estimate and the level of certainty indicator, and to determine whether a certificate should be issued to an individual based on the level of certainty indicator; and a certificate authority to issue the certificate upon determining that the certificate should be issued, wherein the certificate will allow an individual to use the computing device to access an information system.
