A system can detect a change associated with a subscriber identity module (SIM) of a wireless device and generate a data record indicative of the change. In one example, the data record is stored on a digital ledger residing on a cryptographically secured and distributed peer-to-peer network (e.g., blockchain) that stores multiple data records of changes to SIMs of wireless devices. The system can determine whether a wireless device is impacted by malicious activity based on an age of its data record stored on the distributed ledger. For example, an aged data record indicates a lower probability that the wireless device was the subject of a SIM swap fraud whereas a newer data record indicates a higher probability of a SIM swap fraud.

Cross-carrier digital ledger for subscriber identification module (SIM) related data

A content delivery platform may deliver program content segments and advertising content segments to multiple user devices. The content delivery platform may deliver a program content segment to a primary user device of a user for presentation on the primary user device. The content delivery platform may retrieve an advertising content segment from an advertising content store for presentation. The advertising content segment is provided by an advertiser that is sponsoring the presentation of the program content segment on the primary user device. The content delivery platform may send the advertising content segment to a secondary user device of the user for presentation at the secondary user device.

Virtual currency for managing advertising and content delivery

Systems and methods are described herein for facilitating access to a telecommunications network by a third-party device via one or more available subscriber devices. The network-based systems enable devices associated with subscribers of the telecommunications networks to establish connections with other mobile devices (e.g., third-party mobile devices of users that are not subscribers) over peer to peer (P2P) communication protocols. For example, a subscriber device can, over a P2P connection, act as a Hotspot, Wi-Fi tether, or bridge for a third-party or other device requesting access to the networks.

Facilitating telecommunication network access via mobile device peer to peer sharing

Systems and methods are described herein for determining a current condition of an electronic device configured to communicate over a wireless network. For example, the method can include collecting units of condition data of the electronic device. In some instances, each unit of condition data is generated by a sensor of the electronic device that performs an ongoing measurement of a parameter of the electronic device or detects an occurrence of an event that affects the condition of the electronic device. The electronic device provides the units of condition data over a network to a manager node. The units of condition data are then stored in a distributed ledger. The network node can determine a current condition of the electronic device based on the units of condition data stored in the distributed ledger.

Distributed ledger for tracking a condition of an electronic device

Systems and methods are described herein for provisioning a home automation hub, or one or more of IoT devices, with blockchain nodes (or sub-nodes). The hub, an IoT device, and/or a group of IoT devices can perform operations similar to a node on a blockchain network. The operations can include blockchain transactions and other operations, such as transactions performed to verify or confirm an IoT device is authorized to be part of the shared network and thus is authorized to connect to the hub.

Managing internet of things devices using blockchain operations

Systems and methods are described herein for providing mobile devices with peer to peer access to telecommunications networks. The network-based systems enable mobile devices associated with subscribers of the telecommunications networks to establish direct connections with other mobile devices (e.g., third party mobile devices of users that are not subscribers) over peer to peer (P2P) communication protocols. For example, a mobile device can, over a P2P connection, act as a Hotspot, Wi-Fi tether, or bridge for a third party or other mobile device requesting access to the networks.
