Abstract

During the Covid-19 pandemic, there were two popular Covid-19 variants, namely Delta and Omicron. A non-laboratory approach is needed to detect the Delta and Omicron variants of Covid-19 to prevent a high risk of exposure to these two variants. This study proposes the detection of COVID-19 variants of Delta and Omicron using computerized tomography scan (CT-scan) images of the lungs using distance-based classification. There are 5 distance-based classification methods used to determine the best performance for the Delta and Omicron variant Covid-19 classification. Performance is measured based on the comparison of accuracy, precision and recall of each distance method. The distance method used in this study is Euclidean, Manhattan, Minkowski, Chebyshev, and Canberra. The dataset used was downloaded from the Kaggle database. There are 440 total CT-scan images of the lungs which are divided into 220 Covid-19 images of the Delta and Omicron variants and 220 non-Covid-19 images as training data. Meanwhile, there are test data of 140 Covid-19 images for the Delta and Omicron variants and 140 non-Covid-19 images. Based on the comparison of the performance of distance-based classification, it is concluded that the Manhattan Distance has the best performance compared to the other 4 distance methods. Manhattan distance has an accuracy of 58.57%, precision of 56.52%, and recall with a value of 74.28%. Meanwhile, the lowest accuracy value is owned by the Eucliean Distance of 48.21%. Then, the Minkowski distance has the lowest precision and recall with values ​​of 48.41% and 54.28%.

Abstract

The widespread distribution of digital images on the internet has diminished the copyright protection associated with them. In some cases, copyrighted and economically valuable digital images should not be modified or distributed without permission, as altering the original image can harm its owner. This violation is common, but many internet users are unaware of it. The goal of this research is to protect intellectual property rights of digital images using visual cryptography based on the Hill Cipher algorithm with matrix key flexibility. Hill Cipher is chosen for its ability to encrypt data in blocks, making it more secure than classical cryptographic algorithms that encrypt data individually. Visual cryptography is used to secure digital images through encryption and decryption. Encryption scrambles the image, while decryption restores it. The research method involves collecting digital image datasets, preprocessing, Hill Cipher encryption, and decryption. Key flexibility includes matrix keys of 2x2, 3x3, and 4x4 to enhance security. This research has demonstrated the effectiveness of the Hill Cipher algorithm in protecting digital images through encryption and decryption processes with flexible matrix keys of size 2x2 and 3x3. The results of the experiments, including encryption and decryption using both matrix sizes, have been thoroughly analyzed with respect to various cryptographic metrics: histogram analysis, energy, entropy, and running time.
