<h2>About Me</h2>
<div class="about-content">
<div class="about-text">
<p>A forward-thinking Cyber Security specialist with a Master's degree, and a portfolio-defining dissertation project in cryptographic imagery verification. The project, titled "AuthMark", demonstrates an exceptional ability to architect, develop, and validate a complete security solution in Python to counter the rapidly evolving threat of synthetically generated media.</p>
<p>I'm eager to apply my practical experience in secure development, steganography, and wider threat analysis, and mitigation, to help organisations develop resilient, and adaptive, defences against modern cyber threats.</p>

<h3>AuthMark: Cryptographically-Verifiable Media Authentication</h3>
<p class="project-date">September 2024 – August 2025</p>
<p>I designed, and implemented, a novel and proactive system to directly address the "Erosion of Trust" in digital media, by providing a cryptographic link between the human author and their work.</p>
<ul class="project-highlights">
<li>Engineered a hybrid, Python-based system, that embeds a SHA-256 hashed, and a Ed25519 (EdDSA) digitally-signed payload into an image's Discrete Cosine Transform (DCT) mid-frequency coefficients.</li>
<li>Achieved superior quantitative watermark imperceptibility, validated by an average Peak Signal-to-Noise Ratio (PSNR) of 47.06dB, and a Structural Similarity Index (SSIM) of 0.994 – far greater than the accepted industrial threshold of object imperceptibility.</li>
<li>Built a robust framework resilient to common image manipulations, achieving 100% watermark recovery against JPEG compression down to a Quality Factor (QF) of 55%.</li>
<li>Integrated a hierarchical AI detection workflow using "DMImageDetection", a model openly available on Hugging Face, to proactively mitigate the issue of undesired synthetic imagery watermarking.</li>
<li>Deployed as a lightweight web application, with a comprehensive RESTful API, using Flask, and Flask-RESTX, prioritising accessibility, ease of integration, and hypothetical vast scalability to other web platforms with varying purpose and available computational resources.</li>
<li>Validated the system's real-world efficacy through a ten-person blind study, whereby its 95.92% accuracy in identifying authentic media surpassed average human perception.</li>
