Abstract: A method for detecting digital content misuse can include clustering, by a digital content delivery system, a set of data points into a set of digital content usage clusters, each data point from the set of data points representing a unique user account from a set of user accounts maintained by the digital content delivery system, and each data point from the set of data points having been determined based on usage signal data describing digital content usage associated with the unique user account represented by the data point; determining, based on the set of digital content usage clusters, that a first data point from the set of data points is an outlier; and in response to determining that the first data point from the set of data points is an outlier, executing a remedial action with respect to a user account represented by the first data point.

Abstract: A method for preventing digital content misuse can include detecting, by a client-side computing device, that the client-side computing device is paired to a viewing device such that, after being paired, the client-side computing device can cause digital content received from a remote server to be presented on a display of the viewing device; after detecting that the client-side computing device is paired to the viewing device, detecting, by the client-side computing device, that the client-side computing device has been unpaired from the viewing device; and in response to detecting that the client-side computing device has been unpaired from the viewing device, executing a remedial action.

Abstract: A method for preventing digital content misuse can include presenting, by a client-side computing device, digital content that was received from a remote server; detecting, by the client-side computing device, a number of mobile computing devices that are within a geographic distance of the client-side computing device; determining, based on the number of mobile computing device that are within the geographic distance of the client-side computing device, that a number of users viewing the digital content exceeds a threshold number of authorized users associated with the digital content; and in response to determining that the number of users viewing the digital content exceeds the threshold number of authorized users associated with the digital content, executing a first remedial action.

Abstract: A method for preventing digital content misuse can include receiving, by a client-side computing device, digital content from a remote computing system; periodically presenting sonic signals to confirm that a mobile computing device of a user authorized with the client-side computing device is within a desired geographic distance of the client-side computing device; receiving, by the client-side computing device, a notification that a number of unconfirmed sonic signals exceeds a threshold number of allowable unconfirmed sonic signals, wherein the number of unconfirmed sonic signals indicates a number of sonic signals presented by the client-side computing device that the mobile computing device did not confirm detecting; and in response to receiving the notification that the number of unconfirmed sonic signals exceeds the threshold number of allowable unconfirmed sonic signals, executing a remedial action.
