Laptop tamper detection system: A software-based approach for monitoring unauthorized laptop movement

Laptops store personal, academic, and professional information and are frequently carried between homes, classrooms, offices, and public places. Conventional security mechanisms such as passwords and PINs mainly control digital access; by themselves, they do not provide continuous awareness of physical movement or possible tampering. This paper presents the design of a Laptop Tamper Detection System, a browser-based security monitoring prototype intended to demonstrate how suspicious movement events can be identified, reported, and recorded. The system provides a protection dashboard, configurable detection sensitivity, a tamper-event decision process, alarm and browser-notification interfaces, and a timestamped event history. The current academic demonstration uses software-generated or simulated movement events so that the workflow can be tested without additional physical sensors. Browser motion-sensor integration is treated as a possible extension and is not claimed as a validated feature of the present simulation. The paper describes the system architecture, rule-based detection workflow, implementation technologies, representative test cases, benefits, and limitations. The proposed design offers a low-cost starting point for demonstrating physical-security monitoring, while further device-level testing is required before it can be considered a dependable real-world antitheft solution
