A method, system and computer program for deepfake detection in video digital content are provided. Comprises obtaining a video digital content of a user; extracting the audio and video thereof; performing a verbal speech-based detection analysis by transcribing the extracted audio into text and checking whether a speech content is coherent, contextually relevant and/or aligns with an expected topic; performing a voice tonality detection analysis by generating a spectrogram of the extracted audio and identifying irregularities or artifacts characteristics of manipulated or synthesized voice in the spectrogram; performing a facial cue detection analysis by analyzing expression or mouth movements of the user by identifying and dynamically tracking a landmark of the user and verifying whether the analyzed expression or mouth movements temporally and contextually align with speech phonetics; and determining that the obtained video digital content comprises deepfake content based on the performed verbal speech-based detection, voice tonality detection, and facial cue detection analysis.

A method, system and computer program for anomaly detection in mobile cellular networks are provided. The method comprises generating a graph representation of a plurality of cells; selecting one of the cells of the graph as a target cell; obtaining monitored KPIs of connected neighboring cells of the target cell and of the target cell; predicting expected KPI values in the target cell over a predicting sliding window using the graph representation and the KPIs by a ML context-based predictor; making context-based predictions on the monitored KPIs of the target cell by training the ML context-based predictor using the predicted expected KPI values; calculating an anomaly score by comparing the predicted expected KPI values in the target cell over the predicting sliding window with actual values measured in the target cell over the same period; and determining that an anomaly occurs when the calculated anomaly score exceeds a predefined threshold.

A method and an ALTO server method for advanced processing and exposure of network information are proposed. The method comprises providing an ALTO server formed by modular entities including an exposure module, an ALTO core, ALTO applications, and reading modules; periodically monitoring, by the reading modules, a transport network by generating network status information based on network information collected from network domains; processing, by the core, the generated network status information using a processing functionality of the core, obtaining a network view; receiving, by the exposure module, an advanced network information request from an ALTO client; routing the advanced network information request to one of the applications; providing, by the core, the obtained network view to the application; applying, by the application, an application functionality to the network view, obtaining a response to the advanced network information request; and routing the response to the advanced network information request back to the client.

A method, system and computer programs for securely and efficiently measuring available bandwidth of network paths of an SDN-based network are proposed. The network comprises an SDN controller and a plurality of programmable network devices. The method comprises including a bandwidth monitoring element on the SDN controller and/or on the plurality of programmable network devices of the SDN-based network; executing, by one of the bandwidth monitoring elements, within a measurement round, a real-time available bandwidth measurement of a network path between any two of the plurality of programmable devices by embedding a security mechanism into the probing packets shared between the two programmable network devices based on a data plane protocol relying on cryptographic methods and measuring the available bandwidth of the network path by considering reception time-based information of the probing packets using a single clock.

A method, system and computer program for computing radio coverage maps. The method comprises generating a geographic area scene including an antenna, several buildings surrounding the antenna, and receivers; obtaining a 3D coverage map for the scene using a neural network that converts the geographic area scene to a point cloud with different types of points, including a point for the antenna, coverage points covering the scene and building points capturing the buildings' location and dimensions; converts each point into a node, providing an antenna node, building nodes, and coverage nodes; connects the single antenna node and the coverage nodes to all the building nodes; encodes each node type and records an orientation of each node using both an alpha and beta angle; and defines edges of the 3D coverage map using different features capturing a relationship between connected nodes.

A method, system and computer program for system log compression are provided. The method comprises: obtaining at least one first batch of complete and untampered system log entries; representing the system log entries as a provenance graph, with nodes of the graph representing system entities and edges representing relationships between the system entities, wherein each node and edge of the graph is assigned a set of features; embedding the system entities and relationships within the provenance graph into a continuous multidimensional vector space using an embedding algorithm; identifying expected behavior deviations of the system log entries using the embedded continuous vector space; comparing the identified system log entries that deviate from an expected behavior with a given threshold; and labeling system log entries as anomalous if their deviation is different to or falls outside the given threshold, and compressing the system log entries by discarding those are not labeled as anomalous.

A method and system to increase security in VPN services are provided. The method comprises receiving, at a VPN terminator, a message sent by a first computer device at a first site intended for a second computer device at a second site; encrypting the received message, at the VPN terminator, using a first shared session key, the first shared session key being updated using a first renegotiated session key; and routing, by the VPN terminator, the encrypted message to the second computer device. The method further comprises periodically combining the first renegotiated session key with a first LLB shared secret to generate a first hash function, which is used to create the first shared session key. The first LLB shared secret is computed by hashing a value of at least one selected random seed with another LLB shared secret.

The present invention relates to a tubular handle for bags, intended for single or double incorporation into a bag (2), such as a plastic bag, having a structural configuration comprising a hollow body made of plastic material, preferably comprising a rectangular and elongated sheet made of plastic material, folded lengthwise and joined, by means of a lengthwise seam (1.2), by the respective lengthwise edges of the said sheet overlapping each other. In addition, it comprises a reinforcing mesh sheet (1.3) incorporated inside the described hollow body (1.1).

The invention relates to a profile cap for a swimming pool cover and assembly, a cap for hermetically closing the ends of the hollow profiles, or longitudinal slats, which, when coupled together in an articulated manner, define the safety covering cover to be deployed on the surface of the water in a swimming pool. The cap has a structural configuration mainly comprising an internal closure piece, which is inserted into the end of the profile and acts as an element that seals the longitudinal cavities of the profile so that it floats, and an external closure piece, with a variable width, which in addition to embellishing the end of the profile, acts as a protective element for protecting the profile against the edges of the swimming pool and between profiles. The invention also relates to an assembly consisting of the profile and a cap at each end of said profile.

The present invention relates to a safety profile for a swimming pool covering and swimming pool cover, relating to a longitudinal profile, preferably made of PVC, intended to be coupled to other identical profiles to form a swimming pool cover. The profiles work together in an articulated manner, together with other auxiliary elements, allowing them to be deployed over the water surface of a pool to cover it and provide safety features. The profile is distinguished by an improved geometry that brings technical advantages to its operation, both individually and as a whole, compared to other similar products on the market.
