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

Abstract

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.
