VR Device Authentication via Television Receiver Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual reality (VR) devices face challenges in authenticating users and ensuring secure content playback, particularly in preventing 'account packing' where multiple users share a subscription, and in seamlessly transitioning content playback between devices.
Innovation Solution
A VR device system that uses direct wireless communication with a television receiver to authenticate users through credentials and share encryption keys, allowing decryption of content from an OTT host system, and includes a registration process to ensure physical proximity and periodic key expiration to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct wireless communication is used for authentication between VR device and television receiver, then security against account packing is improved, but device complexity increases
Solution Approach 1:
The television receiver serves as an intermediary authentication authority between the VR device and the content delivery system. The TV receiver verifies credentials and provides encryption keys to the VR device through direct wireless communication, preventing unauthorized account sharing while maintaining system security without requiring the VR device to directly authenticate with the content provider.
2Reliability
If encryption keys are shared between television receiver and VR device, then content playback security is improved, but key management complexity increases
Solution Approach 1:
The encryption key arrangement is made dynamic rather than static. The television receiver periodically updates encryption keys provided to the VR device, and keys have expiration times. This dynamic key management ensures that even if a key is compromised, its usefulness is limited by the expiration time, enhancing security while the automatic update process manages complexity.
Solution Approach 2:
Encryption keys are provided periodically by the television receiver to the VR device rather than once permanently. The periodic reissuance of keys with expiration times creates a time-limited authorization system that prevents long-term unauthorized access while maintaining seamless playback during the key validity period.
3Reliability
If credentials are authenticated through television receiver, then prevention of account sharing is improved, but authentication time increases
Solution Approach 1:
The television receiver performs credential authentication in advance before content playback begins. The VR device obtains authenticated credentials and encryption keys from the TV receiver prior to requesting content, so the authentication process occurs before the user experiences any delay during actual content consumption.
Solution Approach 2:
The television receiver autonomously handles the authentication process without requiring user intervention. The VR device automatically communicates credentials to the TV receiver, which independently verifies them and provides the necessary encryption keys, eliminating manual authentication steps and reducing perceived time loss for the user.

AI summary
Various arrangements are presented for using an electronic device for content playback. A television receiver may provide to the device access to a shared encryption key. The shared encryption key may be used to decrypt content from an over-the-top (OTT) content host system. The device may request content from the OTT content host system using the set of credentials. The device may then receive encrypted content from the OTT content host system, wherein the encrypted content corresponds to the requested content. The encrypted content received from the OTT content host system may be decrypted by the device using the shared encryption key. The device may then output for presentation the decrypted content.
