Solution Overview

Problem

Existing electronic devices lack effective automatic data protection mechanisms, leading to potential information leakage when users forget to configure privacy permissions, as current methods rely on active user configuration and do not differentiate data protection based on sensitivity levels.

Innovation Solution

An electronic device method that automatically determines the privacy level of data based on its semantic meaning and context, using a privacy level identification model, to select appropriate presentation and storage manners, ensuring differential protection and security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If privacy permission is configured for specific information, then data security is improved, but user operation complexity increases and users may forget to configure permissions

Engineering Contradiction:
Improvedata securityVSAvoiduser configuration operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system automatically identifies and classifies data by privacy level without requiring user configuration. The electronic device autonomously performs data sensitivity assessment and applies appropriate protection measures, eliminating the need for users to manually configure privacy permissions for each data item.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual configuration process is replaced with an automated intelligent system that uses algorithms to identify and classify data. The system substitutes user action with automated data analysis and classification mechanisms that continuously monitor and protect data without user intervention.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If all data is protected with the same high security level, then data security is improved, but access convenience deteriorates

Engineering Contradiction:
Improvedata securityVSAvoiddata access convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

Different protection measures are applied to different data items based on their classified privacy levels. High-sensitivity data receives stronger protection while low-sensitivity data has easier access, creating localized quality variations in security measures across the data set rather than uniform protection.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system changes security parameters dynamically based on data classification results. Different privacy levels correspond to different security parameters such as authentication requirements, encryption strength, and access control policies, allowing the system to adapt protection intensity to data sensitivity.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If automatic privacy level determination is implemented, then data protection effectiveness is improved, but system complexity increases

Engineering Contradiction:
Improvedata protection effectivenessVSAvoidsystem structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system segments data into distinct privacy levels (first privacy level, second privacy level, etc.) based on sensitivity. This segmentation allows the complex protection mechanism to be divided into manageable categories, where each category has predefined protection rules, reducing overall system complexity through structured classification.

Inventive Principle:
Principle #1Segmentation

AI summary

Embodiments of this application provide a data protection method and an electronic device, and relate to the field of electronic technologies. According to the data protection method provided in embodiments of this application, after obtaining data related to a user in a plurality of manners, the electronic device may automatically determine a privacy degree of the data, for example, a privacy degree of identity information is high, and a privacy degree of itinerary information is low. The electronic device selects, based on different privacy degrees of the data, presentation manners corresponding to the different privacy degrees to present the data when the data needs to be presented, so that data with different privacy degrees can be differentially protected, and privacy security of the user can be ensured.
