This document proposes the development of an anti-theft checker application with three main objectives: 1) To create a system that provides information about stolen objects to help prevent their resale and support law enforcement; 2) To stop criminal activities by allowing users to register stolen items and report thefts online; 3) To make the application accessible across different devices so stolen items can be identified from anywhere. The proposed system would benefit society by reducing street crime and property theft. It would function by having users register stolen items with unique identifiers and then allow reporting an item as stolen online.
