Touch Screen Data Encryption Dragging Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data encryption and decryption processes on terminal devices require multiple steps, including data selection and authentication, making them time-consuming and complex, which negatively impacts user experience.
Innovation Solution
A method and apparatus that utilize a touch screen and fingerprint recognition module to perform data encryption or decryption by detecting a coherent dragging action, allowing for authentication and operation completion in one step, thereby reducing the number of steps and time required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional multistep encryption/ decryption process is used (data selection, authentication confirmation, fingerprint verification), then security authentication is ensured, but operation complexity increases and time consumption increases
Solution Approach 1:
The patent combines data selection and authentication confirmation into a single dragging operation. When the user drags a control element to the fingerprint recognition region, the system simultaneously identifies the target data and triggers authentication, eliminating the need for separate selection and confirmation steps while maintaining security.
Solution Approach 2:
The system pre-positions control elements on the interface that represent encrypted data. The user simply needs to drag these pre-prepared elements to the fingerprint region, rather than navigating through multiple menus and confirmation dialogs, thus simplifying the interaction while preserving authentication integrity.
2Reliability
If traditional multistep encryption/ decryption process is used, then authentication is completed reliably, but time consumption increases
Solution Approach 1:
The patent merges data selection and authentication confirmation into one continuous dragging motion. The system detects the drag gesture, identifies the target data, and triggers fingerprint verification simultaneously, reducing the time required compared to sequential operations while ensuring authentication is still completed reliably.
Solution Approach 2:
The system allows the user to skip intermediate confirmation steps by directly dragging the control element to the fingerprint region. This streamlined path eliminates unnecessary delays from multiple dialog boxes and confirmation prompts, accelerating the overall process while maintaining security through the required fingerprint verification.
3Ease of operation
If control elements are made draggable for encryption/ decryption, then ease of operation improves, but risk of misoperation increases
Solution Approach 1:
The patent makes only specific control elements (those representing encrypted data) draggable, while other interface elements remain static. This localized interactivity reduces the chance of accidental encryption/ decryption operations on wrong elements, as only designated control elements respond to drag gestures.
Solution Approach 2:
The system provides visual feedback during the dragging process, such as highlighting the target fingerprint region or showing the control element's current position. This feedback helps users confirm they are performing the intended operation, reducing misoperations while maintaining ease of use through the intuitive drag gesture.
Data Source
AI summary
A data processing method includes: presenting one or more control elements on the touch screen, where the one or more control elements are in a one-to-one correspondence with one or more pieces of data; and encrypting or decrypting, based on fingerprint data obtained by the fingerprint recognition module, first data corresponding to a first control element when an operation of dragging the first control element from a location outside a second region to the second region is detected, where the second region includes at least a partial region of the first region. This can further complete operations of confirming that encryption or decryption is to be performed and performing authentication in one step, to shorten steps and time of a data encryption or decryption operation, thereby improving user experience.
