Sensor-Based Computer Authentication System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer security methods, such as Smart cards, fingerprint identification, and BIOS passwords, fail to adequately secure computers during usage and require frequent manual input of credentials, leading to inconvenience and potential unauthorized access.
Innovation Solution
A computer information security system utilizing a connection device with a microprocessor and a sensor that generates a second identification code for secure communication, automatically inputting the first identification code to the computer when the sensor is within range, thereby enabling secure access without manual input and entering screen protection mode when out of range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screen protection mode is used to secure the computer during idle time, then unauthorized access is prevented, but the user must repeatedly input username and password, causing inconvenience and time loss
Solution Approach 1:
The system uses the sensor as a self-identifying credential that automatically proves the user's identity to the connection device, eliminating the need for manual password input. The sensor contains stored identification information that is automatically transmitted when placed on the connection device, making the authentication process self-service and convenient.
Solution Approach 2:
The patent replaces the manual mechanical action of typing username and password with an automatic sensor-based identification system. The sensor automatically transmits identification data when placed on the connection device, substituting the manual keyboard input process with an automated electromagnetic signal transmission process.
2Reliability
If traditional authentication methods (Smart card, fingerprint, BIOS password) are used, then computer security is improved, but the system complexity and hardware cost increase
Solution Approach 1:
The sensor serves multiple functions: it contains identification information for authentication, acts as a physical presence indicator, and can be integrated into various devices (remote controls, mobile phones, etc.). This multi-functionality reduces the need for separate dedicated authentication hardware, simplifying the overall system while maintaining security.
Solution Approach 2:
The sensor acts as an intermediary carrier that holds and transmits identification information between the user and the connection device. Instead of requiring complex authentication hardware in the computer itself, the identification data is mediated through the sensor, simplifying the computer's authentication subsystem while maintaining security.
3Ease of operation
If the sensor is placed on the connection device for automatic identification, then user convenience is improved by eliminating manual input, but the risk of unauthorized access when the sensor is left on the device increases
Solution Approach 1:
The system dynamically adjusts its security state based on the sensor's presence. When the sensor is detected, the system transitions to an authenticated state allowing access; when the sensor is removed or not detected, the system transitions to a locked state requiring re-authentication. This dynamic response ensures security adapts to the current usage context.
Solution Approach 2:
The connection device continuously monitors the sensor's presence and provides feedback by automatically locking or unlocking the computer based on detection status. This feedback mechanism ensures that if the sensor is accidentally left on the device, the system will automatically re-lock after a period of non-detection, mitigating unauthorized access risk while maintaining convenience during legitimate use.

AI summary
The present invention relates to a computer information security system and method, the system includes a connection device and a sensor. When the connection device plug in to the predetermined computer, the sensor and the connection device are conjoint, a first identification code can be stored to the computer through the connection device, and generated an initialization setting of the second identification code to the sensor through the connection device. Therefore, when the sensor is out of the predetermined range of the connection device, the connection device will control the computer for encoding to prevent unauthorized user to use the computer; when the sensor is located within the range of the predetermined range of the connection device, the connection device will automatically input the first identification code to the computer to enable the user to directly use the computer without inputting the first identification code to avoid the complicated procedure of inputting the first identification code when the user return to work on the computer, thus to reinforce the security to the information in the computer and to make the operation more convenient.
