Multimedia Device Voice Account Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia devices shared by multiple users face challenges in providing personalized services due to imprecise user preference data, leading to inefficient recommendations and network resource waste, as they lack the ability to distinguish between users.
Innovation Solution
The implementation of a method where multiple second accounts are associated with a single first account on a multimedia device, allowing for voice instruction-based identification of the currently used account, retrieval of user preference information, and provision of personalized services tailored to each user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If one account is assigned per user for multimedia device access, then user identification precision is improved, but device complexity and account management difficulty increase
Solution Approach 1:
The patent segments the account system into two hierarchical levels: first accounts (device-level access) and second accounts (user-level identification). This segmentation allows the system to maintain simple device-level access control while enabling precise user-level identification through associated second accounts, thus resolving the contradiction between identification precision and management complexity.
Solution Approach 2:
The first account serves multiple functions: it acts as both a device access credential and a parent account that can associate multiple second accounts. This multi-functionality reduces the need for separate account structures, simplifying overall account management while maintaining precise user identification capabilities.
2Adaptability or versatility
If personalized services are recommended based on user data, then service personalization is improved, but information disturbance and network resource consumption increase
Solution Approach 1:
The patent applies local quality by retrieving and applying user preference information locally at the multimedia device level rather than continuously querying remote servers. The preference information is cached and used to filter and personalize service recommendations locally, reducing network traffic and resource consumption while maintaining high personalization quality.
Solution Approach 2:
User preference information is retrieved and stored in advance before actual service delivery. This preliminary action allows the system to have user preferences ready when needed, eliminating the need for real-time network queries during service delivery and thus reducing network resource consumption while maintaining personalized service quality.
3Ease of operation
If voice instructions are used for account identification, then user experience convenience is improved, but account security requirements increase
Solution Approach 1:
The system uses voiceprint features as an intermediary layer between the user and the account system. Instead of directly using voice commands for authentication, the voiceprint feature extraction and matching process serves as a secure intermediary that verifies user identity before granting access, thus maintaining both convenience and security.

AI summary
The present disclosure discloses an information processing method, a service providing system, and a computer storage medium. The method includes: assigning at least one first account for a multimedia device; assigning a plurality of second accounts associated with the first account for the multimedia device, each second account representing one user identifier; acquiring a voice instruction; determining a currently used second account according to the voice instruction; searching for user preference information associated with the currently used second account; and providing, based on the user preference information and service request information determined based on the voice instruction, a first service to the user identifier represented by the currently used second account.
