Screen Unlocking via Contact Information Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen unlocking methods for electronic devices with touchscreens are either complex and cumbersome, such as inputting numeric or letter passwords, or insecure, like the slide-to-unlock method, which can be easily compromised.
Innovation Solution
A method that detects a user's intent to unlock the screen by extracting contact information from the device's storage unit, displaying specific attribute values, and requiring the user to match these values to unlock the screen, thereby increasing security and convenience for authorized users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a numeric or letter password is used for screen unlocking, then security is improved, but device complexity and ease of operation deteriorate due to the need to create and memorize passwords
Solution Approach 1:
The patent extracts personal information (contact names, photos, relationship labels) from the device's storage unit and uses it to generate unlocking patterns. This replaces traditional passwords with information that is already stored and familiar to the user, eliminating the need to create and memorize separate passwords while maintaining security.
Solution Approach 2:
The system uses the user's own stored contact information to create the unlocking mechanism. The personal data that the user already has and remembers (contact names, photos, relationships) serves dual purposes: both as stored information and as the basis for secure authentication, making the system self-sufficient.
2Ease of operation
If a slide-to-unlock method is used, then ease of operation is improved, but security deteriorates because the method is easily compromised
Solution Approach 1:
The patent transitions from a one-dimensional slider movement to a two-dimensional pattern drawing on the grid. Users draw patterns by connecting contact information elements (photos, names, relationship labels) on the grid interface, adding spatial complexity and making unauthorized unlocking significantly more difficult while maintaining user convenience through familiar personal data.
3Reliability
If traditional password methods are used, then security is improved, but usability deteriorates due to the complexity of creating and inputting passwords
Solution Approach 1:
The stored contact information serves multiple functions: it is used for communication purposes and simultaneously serves as the basis for secure authentication. This multi-functionality eliminates the need for separate passwords, improving usability while maintaining security through the same personal data.

AI summary
A method for unlocking a screen of the electronic device are provided. The method includes: detecting, in a screen-locked state, intent of a user to unlock the screen; if it is detected that the user intends to unlock the screen, extracting contact information from the storage unit of the electronic device, where the extracted contact information includes a first attribute value and second attribute values; displaying the first attribute value of the extracted contact information on the screen and displaying the second attribute values in a selectable manner; and detecting an operation of choosing a second attribute value by the user, and comparing the second attribute value chosen by the user with a second attribute value that is in the storage unit and corresponding to the displayed first attribute value; if the two values are the same, unlocking the screen; and otherwise, maintaining the screen-locked state.
