Social Network-Based Dynamic Unlocking Interface for Handheld Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unlocking methods for handheld devices, such as button combinations and password entry, are cumbersome and reduce the ease of use.
Innovation Solution
A method utilizing a social network to create a dynamic unlocking interface on a touch screen, where primary and secondary keys from friend information are used to generate questions, allowing users to unlock the device by corresponding input events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional button combinations or password entry procedures are used for unlocking, then device security is maintained, but user convenience and ease of operation deteriorate
Solution Approach 1:
The patent introduces social network information as an intermediary element in the unlocking process. Instead of directly using traditional passwords or button combinations, the system mediates authentication through socially-derived questions and answers about friends, creating a more natural and convenient interaction while maintaining security through socially-verified knowledge
2Reliability
If complex passwords or input events are required for unlocking, then unlocking security is improved, but device complexity and user burden increase
Solution Approach 1:
The patent changes the parameter space of authentication from traditional passwords to socially-derived questions and answers. By transforming the authentication mechanism to use social network information (friends' names, relationships, interactions), the system maintains security while reducing the cognitive burden of creating and remembering complex passwords
3Reliability
If users must create and memorize passwords or input events, then unlocking security is maintained, but time consumption and user burden increase
Solution Approach 1:
The system performs preliminary action by pre-generating unlocking questions and answers based on social network information during device setup or idle periods. This eliminates the need for users to spend time creating and recalling complex passwords during actual unlocking events, as the socially-derived authentication data is prepared in advance through automated social network queries

AI summary
A method for unlocking a handheld device with a touch screen includes accessing a social network using login information, acquiring information of a plurality of friends from the social network. The method further includes creating an unlocking interface on the touch screen according to a second amount of a secondary key based on the plurality of friends and a question based on the first amount of a primary key based on the plurality of friends. An input event of a user on the unlocking interface is detected the handheld device is transitioned from a lock state to an unlock state upon the condition that the input event corresponds to a correct answer.
