Abstract: A secure authorization method and system. The method includes providing, an XFA authorization backend having registered therein a user that wants to protect access or protect the performance of an operation on an Internet-connected asset having a service backend computer where the asset is assigned to the user through an identifying element; receiving, by the XFA backend, one or more user-configurable security factors that are linked to a producer service and provide information about the user. When the user wants to access the asset or the performance of an operation on the asset, the XFA backend receives a checking enquire for at least one of the user-configurable security factors, and in response to the checking enquire, the XFA backend checks if the user fulfils the enquired user-configurable security factor/s using the identifying element, and authorizes or denies the access or the performance of the operation based on the checking.

Abstract: A method and an orchestration server for packet data network service slicing over a network infrastructure for real-time IP services are provided. The method comprises providing an orchestration server that has knowledge of a whole connectivity status of a network infrastructure and that is configured to manage service nodes. The server receives a session request for a real-time IP service from a UE device located in a given region and requests to one or more service nodes of said given region whether it has/they have network resources. Each of the one or more service nodes compute a QoS measurement thereof in terms of KPIs including latency, jitter and bandwidth, the QoS measurement being computed by a software module that is implemented on a virtual machine deployed on the service node; and tag a plurality of interfaces. The orchestration server selects a given service node in view of said QoS measurement.

Abstract: A method for modelling a shape of data in a GAN comprising a generator agent (G) for generating synthetic data (110, 220) and a discriminator agent (D) for distinguishing between the generated synthetic data (120, 220) and real original data (110) that follow an arbitrary, continuous or discrete, distribution defined by a n-dimensional vector of input variables xi. The method, before generating output synthetic data (220), computes an Inverse Smirnov transformation fSi?1 for each of the n input variables xi and attaches an activation function (200) to the generator agent (G), wherein the activation function (200) is a n-dimensional vector faG formed by the computed Inverse Smirnov transformations, faG=(fS1?1, fS2?1, . . . , fSn?1). The GAN implementing the method generates the output synthetic data (220) using the activation function (200) which outputs synthetic data (220) with a distribution (420, 420?) whose shape is the same as the arbitraty distribution of the original data (110).
