TV to Mobile Data Transfer via QR Code
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart TVs and set-top boxes provide an untrusted environment, limiting secure data entry for interactive features, such as payment transactions and sensitive information processing.
Innovation Solution
Encoding a dataset from a television receiver into an optoelectronically readable code, which is scanned and decoded by a mobile terminal, allowing secure data transfer into a trusted environment for processing, using technologies like QR codes and URL-based storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a smart TV or set-top box is used to process sensitive data for interactive applications, then the functionality and user experience are improved, but the security and trustworthiness of data processing deteriorate due to the untrusted environment
Solution Approach 1:
The patent extracts the sensitive data processing function from the untrusted TV environment and relocates it to a trusted mobile terminal. The TV generates and displays a machine-readable code containing processed data, while the mobile terminal scans and handles the sensitive operations, effectively separating the interactive functionality from the security-critical processing.
Solution Approach 2:
The patent introduces a machine-readable code as an intermediary carrier between the TV and mobile terminal. This code acts as a secure bridge, transferring processed data from the untrusted environment to the trusted environment without exposing sensitive information during transmission, thus maintaining both functionality and security.
2Reliability
If data is transferred from TV to mobile device using optically readable codes, then the security and trustworthiness of data processing are improved, but the complexity of the system increases due to additional components and processes
Solution Approach 1:
The patent uses a machine-readable code as a copyable representation of the processed data. Instead of directly transferring sensitive data through complex communication protocols, the system creates an optical copy (the code) that can be scanned and decoded, simplifying the transfer mechanism while maintaining security through the trusted mobile terminal environment.
3Ease of operation
If machine readable codes are used for data transfer, then the ease of operation and user convenience are improved, but the loss of information may increase due to encoding and decoding processes
Solution Approach 1:
The patent replaces manual data entry or direct connection methods with an optical scanning mechanism. The mobile terminal's camera scans the machine-readable code displayed on the TV, automatically capturing and decoding the data. This substitution improves ease of operation while maintaining data integrity through automated, error-minimized transfer processes.

AI summary
A technique for transferring a dataset from a television receiver to a mobile terminal is disclosed. A method implementation of the technique comprises encoding (S202), by the television receiver, a dataset to be transferred to the mobile terminal into an optoelectronically readable code, displaying (S204), by the television receiver, the optoelectronically readable code on a display of the television receiver, scanning (S206), by the mobile terminal, the displayed optoelectronically readable code from the display of the television receiver, and decoding (S208), by the mobile terminal, the scanned optoelectronically readable code to obtain the dataset.
