Mobile Terminal Memo Storage for Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a growing concern about the exposure of personal information as phone numbers stored in mobile terminals can be automatically linked to social networking services, leading to the leakage of private information, and existing technologies lack effective methods to manage and separate frequently used phone numbers for different purposes.
Innovation Solution
A mobile terminal is designed to include a memory unit separate from the address book, allowing users to store memos associated with phone numbers not stored in the address book, enabling users to manage and display these numbers and their associated information conveniently, thereby preventing unintended sharing of personal data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If phone numbers are automatically linked to social networking services, then communication functionality is improved, but user privacy is compromised due to exposure of personal information
Solution Approach 1:
The patent segments phone numbers into two distinct categories: frequent numbers stored in the address book and non-frequent numbers stored separately in a memo. This segmentation allows the system to selectively link only frequent numbers to social networking services, thereby maintaining communication functionality while protecting privacy by excluding non-frequent numbers from automatic linking.
2Ease of operation
If all phone numbers are stored in the address book, then contact management is simplified, but privacy protection is reduced as all numbers become accessible to social networking services
Solution Approach 1:
The patent extracts non-frequent phone numbers from the address book and stores them separately in a memo associated with communication records. This extraction ensures that only frequent numbers remain in the address book and are linked to social networking services, while non-frequent numbers are isolated and protected from automatic linking, thus preventing information leakage.
3Object-affected harmful factors
If a separate memory unit is created for non-address book numbers, then privacy protection is improved, but device complexity increases
Solution Approach 1:
The patent implements a memo structure that serves multiple functions: it stores non-frequent phone numbers, associates communication records with these numbers, and provides a interface for user interaction. By making the memo multi-functional, the patent avoids creating entirely separate complex systems while still achieving privacy protection through the unified memory management approach.

AI summary
The present disclosure relates to a mobile terminal and methods for entering memo that is associated with a telephone number used in communication. A mobile terminal according to one embodiment of the present disclosure may include a display unit configured to display a record of communication with a telephone number that is not available in an address book of the mobile terminal; and a controller configured to activate a memo input mode to enter a memo associated with the telephone number when the record is selected, store a memo entered in association with the telephone number separately from the address book when the memo is entered through the memo input mode, wherein the controller controls the display unit to display the entered memo associated with the telephone number in response to a communication with the telephone number.
