Abstract: Systems and methods for authenticating access to multiple data stores substantially in real-time are disclosed. The system may include a server coupled to a network, a client device in communication with the server via the network and a plurality of data stores. The server may authenticate access to the data stores and forward information from those stores to the client device. An exemplary authentication method may include receipt of a request for access to data. Information concerning access to that data is stored and associated with an identifier assigned to a client device. If the identifier is found to correspond to the stored information during a future request for access to the store, access to that store is granted.

Abstract: The described method and device serve to remotely communicate or control by using photoluminescent or thermoluminescent molecules. A number of samples containing the photoluminescent or thermoluminescent molecules are irradiated simultaneously and together by gamma, X, ultraviolet or visible rays emitted in a cascading manner from an atomic source or from the target of a linear particle accelerator or of a nonlinear crystal. When the samples are separated, one of them is stimulated, i.e. the master, by a conventional method of infrared or white illumination or by heating, and the partially correlated luminescence of the other(s), i.e. the slaves, is measured. No method exists for interfering between the master and slaves. The slave(s) is/are the only one(s) that can instantaneously receive the signal of the master across all media and at all distances. The method and devices are provided, in particular, for use in communications or control applications.
