Terminal Authentication via Second Device Copying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices without suitable data entry means, such as certain terminals like televisions, cannot access personalized services due to the lack of input mechanisms for authentication data, or face laborious and error-prone entry processes when such means are available.
Innovation Solution
A method that reuses authentication data from a second terminal already authenticated with a service provider, allowing the first terminal to access services without needing its own input means, using a short-range communication network to ensure user proximity and transmit authentication data through a shared network with the service provider.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal is not equipped with input means, then the terminal cannot access personalized services, but adding input means increases device complexity and cost
Solution Approach 1:
The patent introduces a second terminal as an intermediary device that performs authentication on behalf of the first terminal. The second terminal captures authentication data from a display, processes it, and transmits it to the service provider, eliminating the need for the first terminal to have its own input means while still enabling service access
Solution Approach 2:
The authentication data is captured as a visual representation (displayed on a screen) and then copied by the second terminal through image capture or direct reading. This copied data is then used for authentication, replacing the need for direct input through physical means at the first terminal
2Adaptability or versatility
If the terminal is equipped with control means, then the terminal can access services, but the authentication entry becomes laborious and error-prone
Solution Approach 1:
Instead of manually entering authentication data through control means, the system displays the authentication data visually and allows it to be captured/copied by a second terminal. This eliminates the laborious and error-prone manual entry process while maintaining service access capability
Solution Approach 2:
The patent replaces the mechanical input process (manual entry through remote control or keyboard) with an optical/electronic process where authentication data is displayed and captured automatically. This substitution eliminates the need for precise manual manipulation and reduces errors
3Adaptability or versatility
If authentication data is transmitted through a network, then remote authentication is enabled, but security risks increase due to potential interception
Solution Approach 1:
The authentication data is captured as a visual display and copied by a second terminal that is physically close to the first terminal. This copying process occurs locally rather than being transmitted over the network, and only the resulting authentication token is sent through the network, reducing exposure to interception risks
Solution Approach 2:
The second terminal acts as a secure intermediary that performs the authentication data capture and processing in a controlled environment. It then transmits only the necessary authentication token to the service provider, minimizing the transmission of sensitive raw data and reducing security risks

AI summary
The invention relates to a method for authenticating a user (UT) of a so-called first terminal (TRM1) capable of communicating with a service provider (SRV) through a first communication network (RES1), said provider requiring the authentication of the user of the first terminal before providing a service to the first terminal, characterized in that the authentication of the user is based on authentication carried out by the user with respect to a second terminal (TRM2).
