International Journal of Advanced Computer Science and Applications, Journal Year: 2022, Volume and Issue: 13(6)

Published: Jan. 1, 2022

Along with the development of Covid-19 pandemic, many responses and news were shared through social media. The new vaccination promoted by government has raised pros cons from public. Public resistance to covid-19 will lead a higher fatality rate. This study carried out sentiment analysis about vaccine using Support Vector Machine (SVM). research aims public response acceptance program. result can be used determine direction policy. Data collection was taken via Twitter in year 2021. data then undergoes preprocessing methods. Afterward, is processed SVM classification. Finally, evaluated confusion matrix. experimental shows that produces 56.80% positive, 33.75% neutral, 9.45% negative. highest model accuracy obtained RBF kernel 92%, linear polynomial kernels 90% accuracy, sigmoid 89% accuracy.

Software-Defined Networking (SDN): A Review

2022 5th International Conference on Information and Communications Technology (ICOIACT), Journal Year: 2022, Volume and Issue: unknown, P. 30 - 35

Published: Aug. 24, 2022

The Internet of Everything (IoE) connects millions machines, vehicles, nodes, smoke detectors, watches, glasses, webcams, and other devices to the internet. These entities need proper guidance control for expected performance. There is always a manage their networks better performance properly. However, managing all these not easy; it big concern. All types network architectures are getting enhanced daily, traditional management process becomes more complex, especially rendering during technology entity modifications. Software-Defined Networking (SDN) extensively used in networks, future technologies (IoT, IoV, 6G, AI, etc.) tackle such concerns issues. as with any new phrase or paradigm, no clear description this has emerged yet, which will give complete understanding SDN, from basic terminology its capabilities. contribution research article significant step forward basics SDN. This proposes detailed review SDN form history, overview, architecture, benefits, services, trends, application, features, challenges.

ECDSA-based Tamper Detection in Medical Data Using a Watermarking Technique

International Journal of Cognitive Computing in Engineering, Journal Year: 2024, Volume and Issue: 5, P. 78 - 87

Published: Jan. 1, 2024

Telemedicine is a form of healthcare delivery that employs communication technology to provide medical care patients remotely. The use telemedicine has seen significant increase in recent years, presenting challenges such as patient privacy, data security, the need for reliable technology, and potential misdiagnosis without physical examination. Digital Watermarking can assist addressing issues by incorporating unique identifier into image be used authenticate its validity. To tackle these issues, this study proposes robust digital watermarking approach tailored brain images, combining hashing, Elliptic Curve Signature Algorithm (ECDSA), Integer Wavelet Transform-Discrete Cosine Transform (IWT-DCT). This method utilizes Secure Hash (SHA-256) first segment brain's Region Interest (RoI). Subsequently, hashed RoI, along with an ECDSA signature, embedded high-frequency sub-bands using IWT-DCT. embedding process strategically alters coefficients accommodate signature while minimizing perceptual distortion. technique leverages robustness transformed-domain techniques against various attacks combines it SHA-256 integrity authentication purposes. results demonstrate suggested variety processing techniques, including noise addition, filtering, compression maintaining high levels imperceptibility. Key metrics Peak Signal-to-Noise Ratio (PSNR), Mean Squared Error (MSE), Structural Similarity Index (SSIM) were evaluate performance. strategy exhibited substantial improvement over existing methods. PSNR increased 68.67, indicating higher quality, MSE reduced 0.96, demonstrating closer pixel values original image. Moreover, SSIM reached 0.98, denoting nearly perfect resemblance between watermarked images. also demonstrated quick extraction speeds, well tamper detection capabilities.

This paper proposes a new block mapping technique for image authentication and self-recovery designed to avoid the tamper coincidence problem called AuSR3. The can arise when modifications an affect original its recovery data, resulting in inability recover tampered region of image. ensures that data is embedded into most distant location possible, minimizing problem. In addition, improved LSB shifting algorithm employed embed watermark consisting data. experimental result shows AuSR3 produce high-quality watermarked images across various datasets with average PSNR values 46.2 dB, which by 2.1 dB compared replacement technique. avoids up 25% tampering rates. It contributes recovered SSIM value 39.10 0.9944, respectively, on 10% rate USC-SIPI dataset.
