Terminal Security via Printer-Based Authentication Clue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices store sensitive user information, and if stolen, there is a risk of privacy leakage due to lack of effective security measures to prevent unauthorized access and trace the stolen device.
Innovation Solution
A method and device that determine if an illegitimate user is accessing a terminal, and upon detection, send authentication information to a preset printer for printing, which can include user information such as face or fingerprint data, to help the legitimate user recover their device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication information is sent to a preset printer when an illegitimate user is detected, then terminal security is improved, but device complexity increases
Solution Approach 1:
The system pre-configures a printer device as a trusted output endpoint before security incidents occur. When an illegitimate user is detected, the system immediately sends authentication information to this pre-established printer, enabling rapid response without requiring complex real-time device selection or user intervention.
Solution Approach 2:
The printer serves as an intermediary device that receives authentication information from the terminal and produces physical copies. This intermediary approach allows the system to securely distribute authentication data without requiring direct access to the terminal by the legitimate user, thus improving security while maintaining system simplicity.
2Ease of operation
If authentication information and user information are sent to the printer, then the legitimate user can recover their device more effectively, but information loss increases due to potential data leakage
Solution Approach 1:
The system differentiates between types of information sent to the printer: authentication information (necessary for device recovery) and user information (such as face or fingerprint data). By selectively sending only the minimum necessary authentication data rather than all user data, the system enables effective device recovery while minimizing privacy information leakage.
Solution Approach 2:
The system extracts and sends only the essential authentication information required for device recovery to the printer, separating this from sensitive user information that remains protected in the terminal. This extraction approach provides the legitimate user with sufficient data to recover their device without exposing unnecessary personal information.
3Reliability
If the system sends authentication information through a server or another terminal, then reliability is improved, but loss of time increases due to additional transmission steps
Solution Approach 1:
The system pre-configures a printer device as a trusted output endpoint before security incidents occur. When an illegitimate user is detected, the system immediately sends authentication information to this pre-established printer, enabling rapid response without requiring complex real-time device selection or user intervention.
Solution Approach 2:
The terminal automatically detects illegitimate user access and independently sends authentication information to the preset printer without requiring user intervention or complex routing decisions. This self-service approach minimizes response time while maintaining reliability through automated security protocols.

AI summary
The present invention relates to a method, a device and a storage medium for printing information. The method includes: acquiring authentication information of a current operator of a terminal; determining whether the current operator is a legitimate user according to the authentication information of the current operator; and sending the authentication information to a preset printer when the current operator is an illegitimate user. In the technical solution, when it is determined that the current operator is an illegitimate user, the authentication information of the current operator is sent to a preset printer, in order for the preset printer to print the authentication information. It can improve the security of the terminal, and thus improve the user experience.
