Robot Account Share Token for Secure Media Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for accessing media content often require transmitting user credentials, which can lead to security risks due to potential interception by third parties, such as hackers, during the transmission process.
Innovation Solution
A system where a media request from a user device includes a robot account email address and a media ID, which are sent to a media provider, generating a share token that is encrypted and used for media playback without transmitting user credentials, ensuring secure authorization and minimizing exposure of sensitive information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user credentials are transmitted to enable media content access, then authentication and authorization can be performed, but security risks increase due to potential interception by third parties
Solution Approach 1:
The patent introduces a robot account as an intermediary entity between the user device and the media server. Instead of transmitting user credentials directly, the system uses a robot account with a share token that contains the user's authorization information in an encrypted format. This intermediary mechanism allows the media server to authenticate users without receiving their actual credentials, thereby eliminating the security risk of credential interception while maintaining authentication reliability.
Solution Approach 2:
The patent creates a copy of the user's authorization information within the share token, which is an encrypted representation of the user's credentials. This copy contains sufficient information for the media server to authenticate and authorize media playback without exposing the actual user credentials. The share token acts as a disposable credential that can be transmitted safely, replacing the need to transmit sensitive user information.
2Ease of operation
If user credentials are transmitted for media access, then media playback can be enabled, but data exposure and potential leaks occur
Solution Approach 1:
The patent extracts the sensitive user credential information from the transmission process and replaces it with a robot account share token. The share token is generated by the media server and contains encrypted authorization data, but it does not expose the actual user credentials. This extraction of sensitive information from the transmission channel allows media playback to function while preventing credential exposure and data leaks.
3Object-affected harmful factors
If a share token system is implemented, then credential transmission is prevented, but system complexity increases
Solution Approach 1:
The robot account serves multiple functions within the system: it acts as an intermediary for authentication, stores encrypted share tokens, manages user authorization, and facilitates media playback. By consolidating these multiple functions into a single robot account mechanism, the patent reduces the need for separate complex authentication components, thereby managing system complexity while achieving secure credential transmission prevention.
Data Source
AI summary
Content stored on a server may be selected using a user device and enabled on a central device. The identity of the central device may be authenticated without transmitting user credentials corresponding to the user, user device, user account, etc. A central device identifier can be sent to the server via the user device. An encrypted version of the central device identifier may be returned to the user device and to the central device. The central device can send the encrypted and unencrypted version of the identifier to the server, and the server can transmit the desired content to the remote device based on a comparison of the encrypted and unencrypted identifier.
