Service Access Control via Intermediary Terminal Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for personalizing and controlling access to remote services, such as televised content, do not allow verification of access rights by third-party communication terminals, limiting account holders' control and security.
Innovation Solution
A method for controlling access to services involves transmitting a confirmation request to a first communication terminal associated with a customer account, requiring an authentication code that matches the account's code for access, allowing remote and secure management of services, including channel control and home automation, without the account holder's physical presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If profile creation with code entry or facial recognition is used for service personalization, then access control and personalization are improved, but the ability to verify access rights by third-party communication terminals is lost
Solution Approach 1:
The patent introduces a communication terminal as an intermediary device that receives service access rights from the service provider and transmits them to the playback system. This intermediary enables third-party terminals to verify access rights while maintaining security through authentication codes stored in the terminal's memory, resolving the contradiction between reliable access control and third-party verification capability.
2Reliability
If physical presence of account holder is required for service access control, then security is improved, but ease of remote control and convenience are worsened
Solution Approach 1:
The patent implements preliminary action by having the communication terminal store authentication codes in its memory during initial setup. When service access is needed, the terminal can retrieve and transmit these pre-stored authentication codes to the playback system, enabling secure remote access without requiring the account holder's physical presence at the time of access.
3Adaptability or versatility
If multiple communication terminals are allowed to access services, then versatility and adaptability are improved, but device complexity and access control management are worsened
Solution Approach 1:
The patent applies segmentation by dividing the access control management into separate functional components: the service provider manages authentication codes for each communication terminal independently, and each terminal stores its own authentication code in local memory. This segmentation simplifies the overall system architecture and reduces management complexity while enabling multiple terminals to access services securely.

AI summary
A method for controlling access to televised or audio services provided by a service provider server. The method is implemented by the service provider server and includes: receiving a service request comprising an identifier of a customer account and an identifier of a first communication terminal; transmitting a text message confirmation to the first communication terminal; receiving an authentication code from the first communication terminal; and accessing at least one televised service if the authentication code received is identical to an authentication code stored in a database and linked to the identifier of the customer account.
