Existing System
The existing methods for cheating detection in exam halls often rely on manual
monitoring by invigilators, which can be time-consuming and prone to human
errors.these methods include: visual inspection, surveillance cameras ,proctoring
software .these, methods have limitations such as limited coverage, potential privacy
concerns and inabilities to detect subtle cheating methods.
Proposed System
The proposed system for automatic cheating detection in exam halls will use
YOLOv3 with ShuffleNets to integrate cutting-edge technologies that enhance
accuracy, efficiency, and ethical considerations in monitoring exam environments.

7. System Architecture
The proposed system is made up of several components that work together to
maintain the integrity of an exam hall. These components include the integration of
the YOLOv3 object detection algorithm, which identifies cheating behaviors or
objects such as smartphones, notes, or collaboration between students with high
accuracy. Additionally, the system uses the ShuffleNets architecture to optimize
computational efficiency, enabling real-time detection while reducing computational
resources. A network of strategically-placed cameras provides comprehensive
coverage for video input to the system. To accurately distinguish between normal
activities and potential cheating incidents, the system is trained to classify specific
cheating behaviors. It continuously monitors the exam hall through live video
analysis and immediately flags any suspicious activity through an alert mechanism
developed to notify proctors or administrators in real-time.

8. System architecture
System Operation:
The system is designed to adapt to varying lighting conditions, camera angles, or
exam hall layouts for consistent and reliable performance. The system operates
ethically by respecting individual privacy and focusing solely on relevant cheating
behaviors without unnecessary intrusion. A user-friendly interface is developed for
proctors or administrators, allowing them to monitor the system, review flagged
instances, and take appropriate actions effectively. In operation, the proposed system
continuously analyzes live video feeds from multiple cameras using YOLOv3 with
ShuffleNets, enabling real-time detection of cheating behaviors. Upon identifying
suspicious activities, the system promptly alerts administrators via the user interface,
where they can review flagged instances and take appropriate actions to maintain the
integrity of the examination process.

employed the ShuffleNets architecture. Python is the primary programming language
we use for implementation. Additionally, we have leveraged popular deep-learning
libraries such as TensorFlow and PyTorch for model training and inference.
The estimated timeline for the completion of the first module is as follows: Research
and Design: 1 month, Model Development and Integration: 2 months, Testing and

17. Implementation/Results of Module
The initial module's outcomes aim for robust cheating detection in exam halls using
YOLOv3 with ShuffleNets. Expected results include high accuracy in identifying
cheating behaviors (potentially 90%), efficient real-time performance (averaging 0.1
seconds per frame), and minimized false positives (around 5%) and false negatives
(about 8%). Successful integration with exam monitoring systems, triggering alerts in
95% of detected cheating instances, is crucial. Preliminary performance metrics such
as precision (91%), recall (88%), and F1-score (89%) will be indicators. These
outcomes serve as the foundation for subsequent improvements, guiding further
iterations. Any shortcomings will prompt retraining with more diverse datasets,
adjustments in model parameters, or architectural modifications to optimize the
system's performance. User feedback and real-world testing will drive refinements in
subsequent modules for a more reliable and comprehensive cheating detection system

The proposed model was implemented using Python with Tensor Flow on a core i7
system with Nvidia 1080 ti, and trained with a learning rate of 0.0002, batch size of
1, for 100 epochs, and momenta of 0.091. The training started with a loss of 4.02323,
which gradually reduced to 0.0023. The model was trained on 75% of the total
dataset, with 15% used for validation and 10% for testing. The proposed model
achieved an accuracy of 88.03% on our dataset, while the YOLOv3 model with
transfer learning scored 82.06% accuracy. The proposed model performed better than
the typical YOLOv3, both in terms of time and accuracy. Below Table shows the
detection results of the prepared dataset trained on both deep learning models. The
average precision (AP) of both models indicates that the proposed model
outperformed YOLOv3 with 88.03% accuracy in detecting cheating.
