PIC Verification for Multiscreen DIAL Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing DIAL protocol systems allow a user launching an application on a first screen device to override previously launched applications, disrupting the content being watched by other users on the same network, leading to interruptions and password mismatch issues when trying to display content on different devices.
Innovation Solution
Implementing a personal identification code (PIC) verification system that only allows the user in front of the screen to launch or override the DIAL application, using a PIC displayed on the screen for verification, and automatically switching login accounts to match the client device's credentials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user can launch applications on a first screen device without verification, then the ease of operation is improved, but the reliability of content delivery is worsened due to unauthorized overrides
Solution Approach 1:
The system performs preliminary verification by displaying a personal identification code (PIC) on the screen before allowing application launch. The user must enter this PIC code to prove they are the intended user, preventing unauthorized overrides while maintaining ease of operation for legitimate users
2Adaptability or versatility
If the system allows any user to override launched content, then the adaptability is improved, but the loss of information is worsened due to interrupted content delivery
Solution Approach 1:
The system implements feedback by monitoring whether the entered PIC code matches the displayed code. This feedback mechanism ensures that only the intended user can override content, preventing information loss from unauthorized interruptions while still allowing legitimate users to adapt the display to their needs
3Reliability
If the system requires manual account switching for different devices, then the reliability of authentication is improved, but the ease of operation is worsened due to password mismatch issues
Solution Approach 1:
The system performs automatic account switching based on the device's credentials without requiring manual user intervention. The device automatically provides its identification information, and the system switches accounts seamlessly, maintaining reliable authentication while eliminating the complexity of manual password entry

AI summary
A device including a communication component, a DIAL protocol component, a video processing component and a PIC verification component. The communication component can wirelessly receive a personal identification code, can communicate with a display and can receive first video content from a content provider. The DIAL protocol component can perform protocols in accordance with a multiscreen discovery and launch of first screen content specification. The video processing component can provide first video data including PIC image data corresponding to a code so as to display the first video data and a PIC image on the display. The PIC verification component can generate a verification signal when the personal identification code corresponds to the PIC image data. The video processing component can further provide the first video content to the display based on the verification signal.
