Biometric Presence Detection for Automated Computer Logout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer security systems fail to continuously monitor for the presence of specific authorized users and do not terminate access appropriately when an authorized user is no longer detected, lacking the capability to differentiate between authorized and unauthorized individuals.
Innovation Solution
A computer security system that uses recognition technologies such as infrared emission signatures or facial topography to create a database of authorized users, continuously monitoring for their presence and logging them out if the recognized data is not detected within a defined interval, employing sensors and software to analyze and compare unique identifying characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If motion detection technology is used to monitor presence near the computer, then automated logout capability is improved, but the system cannot differentiate between authorized and unauthorized users
Solution Approach 1:
The patent replaces simple motion detection with biometric recognition technology (fingerprint sensors, facial recognition, iris scanning) that can positively identify authorized users. This substitution transforms the system from detecting mere presence to verifying specific user identity, thereby maintaining automated operation while significantly improving identification reliability.
Solution Approach 2:
The system creates and stores digital copies of authorized users' biometric data during registration. These biometric templates are then used for continuous verification, allowing the system to automatically recognize and identify specific authorized users without manual intervention, thus achieving both automation and accurate differentiation.
2Reliability
If continuous biometric monitoring is implemented to track specific authorized users, then security control is improved, but system complexity increases
Solution Approach 1:
The patent integrates biometric recognition functionality directly into the computer's existing authentication and operating systems. By merging biometric monitoring with the login/logout mechanisms already present in standard computer operations, the system achieves continuous security monitoring without adding separate complex monitoring infrastructure.
Solution Approach 2:
The biometric recognition system operates autonomously, automatically capturing, verifying, and continuously monitoring user presence without requiring manual activation or intervention. The system self-manages the entire process from initial enrollment through ongoing verification and automatic logout, reducing operational complexity despite enhanced security capabilities.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively ensures that only authorized users maintain access to the computer system, preventing unauthorized access by automatically logging out users who are no longer present, thereby enhancing security and workflow continuity.
Implementation Method 1
The sensor is preferably an infrared sensor
Implementation Method 2
The computer is programmed with facial recognition software

AI summary
A computer security system which prevents an unauthorized user from accessing the computer system when an authorized user has already logged onto the computer system and has temporarily left the workstation. The computer security system generally includes a sensor which is configured to detect the presence of a person in the region around a workstation and a processing unit which logs out of the computer when a person is no longer present in the region. An optional calibration tool may be provided to set the sensitivity of the sensor and prevent accidental logging out when the authorized user is still present in the region around the workstation.
