Dynamic location based content rights management

摘要

A system and method for controlling access to digital content based on proximity and location of a user device. A user device connects to a local network and an audio transmission including a perpetually rolling key is transmitted within a geo-fence in the local area. The user device hears the audio transmission and uses the key to authenticate to a content server over the network. Once authenticated, the user device may then stream content from the content server. In order to terminate access to the content when the user device leaves the geo-fence, the content server may require the key to be retransmitted from the user device at regular intervals to re-authenticate the user device. Other factors such as radio fingerprints from the user device may also be used instead of or in addition to the audio to verify the user device's presence within the geo-fence.

主权项

1. A method for controlling access to digital content, comprising:
providing a user accessible wireless network; transmitting a first audio signal within a local area, the first audio signal including a first content access key; receiving a first key confirmation from a user device, wherein the user device received the audio signal and wherein the first key confirmation is based at least in part on the first content access key; receiving a radio fingerprint of the user device, the radio fingerprint including a signal strength of the wireless network detected by the user device; determining the user device is within the local area based at least in part on the radio fingerprint and receiving the first key confirmation; allowing the user device to access digital content via the wireless network based at least in part on receipt of the first key confirmation; changing the first content access key to a second content access key at a predetermined time interval; transmitting a second audio signal within the local area, the second audio signal including the second content access key; determining the user device is outside the local area based at least in part on failing to receive a second key confirmation from the user device; and discontinuing to allow the user device to access the digital content via the wireless network based at least in part on determining the user device is outside the local area.
