Abstract

In an age where automobiles have become the most used method
of transportation, a problem of illegal parking has arisen with insufficient
police officers to enforce the law. Commercial or government-based parking enforcement
programs were developed in order to lessen the load of the police deployed.
The main objective of this study is to prevent false evidence from entering
the system. Digital watermarking technology was imported via LSB transformation
under law enforcement. Among various approaches, the Least Significant Bits
LSB transformation scheme is easy and simple. An Android smartphone with an
app installed was used with a PC desktop that is able to check the key stored
from the application within a Wi-Fi zone. An experiment was performed to extract
the key from an image taken from the smartphone to prevent false evidence.
