Mobile Terminal Backup Mode for Secret Information Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication terminal devices lack clear operation modes for information backup, particularly in distinguishing and handling different types of information, leading to unclear backup operations when information classification changes.
Innovation Solution
A mobile communication terminal device with an information memory unit, a backup request memory unit, and a management unit that classifies information based on secrecy, allowing for secure backup and deletion operations through a communication network, enabling users to set operation modes for backing up or deleting information based on its importance and secrecy attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all information is backed up, then information recovery capability is improved, but security of sensitive information deteriorates
Solution Approach 1:
The patent segments information into multiple categories (secret information, important information, ordinary information) based on importance and secrecy levels. Different backup strategies are applied to each segment, with secret information excluded from backup while important and ordinary information are backed up according to user-defined rules, thus resolving the contradiction between comprehensive backup and security protection
Solution Approach 2:
The patent applies different backup policies to different types of information based on their specific characteristics. Secret information is completely excluded from backup, important information is selectively backed up based on user-defined conditions, and ordinary information is backed up according to standard procedures. This localized quality approach allows each information type to receive appropriate backup treatment, balancing reliability and security
2Object-affected harmful factors
If classification of information is introduced, then security control is improved, but operation complexity deteriorates
Solution Approach 1:
The patent creates a universal classification framework that can handle multiple types of information (contacts, messages, files, etc.) with a single set of classification rules and backup policies. The system automatically applies the same classification logic across different information types, reducing operational complexity while maintaining comprehensive security control
Solution Approach 2:
The system automatically classifies information into secret, important, or ordinary categories based on predefined criteria and user settings, without requiring manual classification of each item. This self-service approach simplifies operations while maintaining security control through automated classification
3Object-affected harmful factors
If secret mode operation is added, then security of secret information is improved, but clarity of backup operation deteriorates
Solution Approach 1:
The patent implements a dynamic operation mode that automatically adjusts backup behavior based on the current secret mode state. When secret mode is enabled, the system dynamically excludes secret information from backup operations. When disabled, normal backup operations resume. This dynamic adaptation maintains security while preserving operational clarity
Solution Approach 2:
The system provides feedback to users about which information is being backed up and which is excluded due to secret mode status. This feedback mechanism clarifies the backup operation by showing users the actual state of information processing, maintaining ease of operation while enforcing security

AI summary
According to an embodiment of the invention, a mobile communication terminal device comprises: an information memory unit configured to store a first information and a security information indicating whether the first information is secret; a backup request memory unit configured to store a first request for backing up identification information of the first information and the first information, or a second request for deleting a second information identified by the identification information with which the first information is stored in the backup device; a transmitting unit configured to transmit the first request or the second request based on the information stored in the backup request memory unit; and a management unit configured to store the identification information of the first information and the first request, if the first information of which the security information indicates that the first information is not secret is stored in the information memory unit.
