Abstract: A technique for multi-factor authenticating a user on a first device, the user having an associated second device configured with an authenticator application, and wherein the authenticator application is offline. In this scenario, and responsive to receipt of a request to access a protected resource, a push notification is sent to the authenticator. While the push notification remains pending, a delivery status of the push notification is requested. Upon determining based on the delivery status that the authenticator is offline, an alert is provided to the user, preferably in a user interface of the first device, and indicates the delivery status of the push notification. The alert also includes an instruction to the user to attempt an authentication through an alternative communication channel. The user is then permitted to access the protected resource only upon completing the authentication through the alternative communication channel.

Abstract: The invention is notably directed to a method of programming memory elements of an in-memory computing (IMC) device. The IMC applies a SET signal to the K memory elements of said each cell to set each of the K memory elements to a SET state and reading K conductance values of the K memory elements in the SET state. The IMC adjusts, based on the K conductance values read and the target conductance value, a conductance value of at least one of the K memory elements to match a summed conductance of the K memory elements of said each cell with the target conductance value. The IMC maximizes a number of the K memory elements that are either in their SET state or in a RESET state of zero conductance nominal value, such that at most one of the K memory elements is neither in a SET state nor in a RESET state.
