The disclosure provides an approach for authenticating a user of a computer system, wherein the computer system implements a virtual desktop infrastructure (VDI), the method comprising connecting to a computing device through a network, receiving from the computing device authentication credentials, and determining whether the authentication credentials match an authorized user of the computer system. The approach further comprises extracting from the computing device features of the computing device, retrieving a machine learning (ML) model associated with the authorized user, wherein the ML model is at least one of (a) a supervised ML model or (b) an unsupervised ML model, and executing the ML model to authenticate the features of the computing device.

A system for sending a relay notification comprises a transceiver and a processor. The processor is configured to use the transceiver to receive a request for allowing a mobile device to be used by a further mobile device as a relay to a mobile communication network. The processor is further configured to determine whether the mobile device is to act as a relay for the further mobile device based on the unique identifier of the further mobile device, and to use the transceiver to notify the mobile device that it is to act as a relay for the further mobile device in dependence on the determination. The mobile device is configured to receive the notification from the system. The processor is further configured to start relaying data received from the further mobile device to the mobile communication network upon receiving the notification.

The techniques described herein include configuration of channels between devices and service providers at a connectable system platform. For example, a system platform may include a receiver to receive data from a communicatively coupled device. The system platform may include a controller having logic, at least partially comprising hardware logic, to configure communications channels. The communication channels include a communication channel for transmission between the system platform and a service provider to receive the data, and a communication channel for transmission between the system platform and the coupled device. The communication channels are configured based on a context. The context comprises characteristics of the coupled device, content of the data, and security requirements associated with the service provider.

In an approach to managing obfuscation of regulated sensitive data, one or more computer processors detect content for display on a computing device. One or more computer processors analyze the content for sensitive data. One or more computer processors retrieve one or more applicable regulations, where the regulations are associated with displaying sensitive data. One or more computer processors determine a location on the display for obfuscating the sensitive data in the content, based on the retrieved one or more applicable regulations. One or more computer processors identify one or more context rules applicable to the sensitive data in the content. One or more computer processors determine the one or more context rules override the one or more applicable regulations. One or more computer processors display the sensitive data in the content.

A method performed by one or more network node(s) of a wireless telecommunications network to dynamically manage encryption keys for multiple narrowband Internet of Things (NB-IoT) devices of the network. The network node(s) can maintain a database that stores a device profile for each of the NB-IoT devices and obtain multiple encryption keys for the multiple NB-IoT devices. The encryption keys are associated with different encryption strengths ranging from high to ultra-low encryption strengths. The network node(s) can allocate the encryption keys to the NB-IoT devices, detect a change in the condition of the network, capability or communications service of NB-IoT devices, and refresh the encryption keys accordingly to ensure that the network nodes properly balance encryption while providing efficient network performance.

A proxy-based method for improving digital security during a user's travel is provided. The method may include determining a bundle of merchant category classification (MCC) codes. This bundle preferably reflects a baseline travel condition. The baseline travel condition is associated with a user mobile device. The method may also include dynamically updating a characteristic associated with the bundle of MCC codes based on updated travel conditions. The method may also include determining an occurrence of an anomalous user mobile device activity. The determination may be based on a comparison of the updated characteristic associated with the bundle of MCC codes and the baseline travel conditions; and in response to a determination of anomalous user mobile device activity, increasing a security level associated with the mobile device associated with the user.

Disclosed herein are a method for ensuring trustworthiness of a packet in a distributed synchronous wireless communication system and an apparatus using the method. The method, performed by terminals and an apparatus for checking the trustworthiness of a packet, includes: transmitting, by a first terminal, a packet including a trust field to a second terminal using distributed wireless communication; receiving, by a third terminal, the packet from the first terminal; requesting, by the third terminal, checking of trustworthiness by delivering the packet and information about the packet reception time to the apparatus; checking, by the apparatus, the trustworthiness of the packet using the trust field and the information about the packet reception time; generating, by the apparatus, a trust result notification packet when the result of checking the trustworthiness indicates that the packet is untrusted; and transmitting, by the apparatus, the trust result notification packet to the second terminal.

A device, system and method for managing access authorization is provided. A request to alter access authorization of one or more devices assigned to a user is received at a computing device. The computing device determines at least one contextual condition associated with at least one of the one or more devices. The computing device determines, based on the at least one contextual condition, a subset of the one or more devices for which the access authorization is to be altered to include at least one other user. The computing device alters the access authorization of the subset of the one or more devices to include the at least one other user, such that the at least one other user is granted access to the subset of the one or more devices.
