Anonymous access may be provided using an authorization gateway. Anonymous access reuses objects in different extended reality environments rather than having each object be restricted to a single environment. Anonymous access increases privacy when using different environments. The user and the extended reality server communicate via an authorization gateway, preventing the extended reality server from directly gathering user information. A token issuing authority may issue tokens in response to payment and forward the payment to an extended reality provider. The user pays the token issuing authority and receives a token that does not identify the user. The token issuing authority forwards the payment to the extended reality provider. The user provides the token to the authorization gateway, which communicates with the extended reality server to provide the extended reality environment to the user. Thus, the user's payment is verified by the authorization gateway without specifically identifying the user.

User privacy in extended reality

Example embodiments provide systems and methods for replacing recorded media content. In an example method, at least one media content source is searched for a media content item recorded to storage of a first media content device. Based on the media content item being found at a first media content source of the at least one media content source, a recording of the media content item to storage of a second media content device is scheduled based on the media content item being recordable from the first media content source at the second media content device. Based on the media content item not being recordable from the first media content source at the second media device, the availability of the media content item is indicated to the second media content device.

Replacement of recorded media content

Systems and methods for managing provisioning of keys prior to a key rotation are provided. A license server generates a license that is associated with a renewal time. The renewal time is a time that is prior to a key rotation time, and triggers a receiver device to send a renewal request prior to the key rotation time. The renewal time may be a randomized time prior to the key rotation time that differs for different receiver devices. The license is transmitted to the receiver device. The license server then receives a renewal request from the receiver device that is triggered at the renewal time. The license server generates a next license that comprises a next key, whereby the next key is a decryption key for decrypting the encrypted signal after the key rotation time. The next license is transmitted to the receiver device prior to the key rotation time.
