Hybrid client-side beacon tracking
The embodiments implement server-side third party content insertion with client-side tracking beacon. The solution embeds third party content within designated breaks of primary content to form a single unified stream that is streamed to a client requesting the primary content. The unified stream allows the client to receive all content without switching between different streams and prevents advertisement blockers running on the client from differentiating the third party content from the primary content and from blocking the third party content. The solution also generates and sends to the client, a configuration containing events and destinations the different content providers define for their respective content. The client monitors for the events specified in the configuration during playback of the unified stream. An event that is triggered causes the client to send a tracking beacon to a content provider specified destination associated with the event. |

Extending audience reach in messaging campaigns using probabilistic ID linking
A server receives incoming data records comprising an ID value and respective user attributes corresponding to a user activity that originates at a user device. Characteristics of the activity and/or characteristics of the user device are considered in order to assign a probabilistic confidence value, which is in turn used to generate links from an incoming data record to other previously-received data records, and in so doing, generates a probabilistic link between one set of user attributes from the incoming data record and another set of user attributes from previously-received data records. A messaging campaign specification that describes target user attributes is used to identify a matching set of target audience member records. The determination of a match or not is based on the probabilistic confidence value and a threshold can be varied to extend audience reach. The identified set of target audience member records are transmitted over a network. |

Method for repeatable creation of random file enables to create and recreate random files at different places, different times and on different devices. Random files are based on aliases, which can contain any text, including specific information, such as serial number, start date, expiry date, etc. Random files can be used for generations of strong and unique passwords. The strength of the password doesn't depend on alias, so any alias will result in equally strong and unique password.Browser, using the method, would be able to register the user to any resource, by generating a password, using resource's URL as alias, and afterwards automatically log user in using same URL for generating the password again.Users can communicate securely by sending alias in plaintext together with ciphertext encrypted with password.IoT devices can establish master, slave, partner, alien relationship and communicate securely without human introduction. |

Interacting with a computing device via identity-bearing peripheral devices
A technique is described herein by which a user may gain access to a target resource via one or more particular peripheral devices that have been associated with the user. The technique performs this task by detecting when a user communicatively couples an identity-bearing component to a hub device.
