Cloud based veins recognition and authentication using CNN

In the current digital landscape, numerous systems require a reliable recognition method to verify the identity of individuals accessing their services. As technology continues to evolve, there's an escalating demand for robust and secure biometric identification. With increasing advancements in the interface between humans and computers, new biometric modalities have emerged and gained traction. Among these, the finger vein has emerged as a particularly compelling area of research. The underlying rationale for this heightened interest is the unique characteristic of the human finger vein, its intricate structure, and the inherent difficulty in counterfeiting or stealing this information. This thesis delves deep into proposing a finger vein-based recognition system tailored for individual identification. The finger vein stands out primarily because of its distinctiveness. Each individual's finger vein pattern is intricate and different, almost akin to the uniqueness of a fingerprint but concealed within the body, making it a challenging target for malicious intents. Unlike external features like facial structures, fingerprints, or iris patterns, which can be potentially copied, mimicked, or stolen, the finger vein remains protected inside the finger, making it an optimal choice for biometric identification. The methodology of the proposed recognition system is built on a series of sequential processes. First, the acquired finger vein image undergoes a preprocessing stage. This initial step is essential to refine the image by removing any superfluous details and enhancing its core features. The color image is transitioned into a grayscale format, streamlining the data and eliminating any color-based anomalies. To accentuate the details and improve clarity, histogram equalization is employed. This technique amplifies the contrast, ensuring that the vital vein patterns stand out prominently. Once the image is preprocessed and enhanced, the system shifts focus towards feature extraction. The choice of feature extraction method is pivotal, as it directly impacts the subsequent identification accuracy. This research leverages the acclaimed Linear Discriminant Analysis (LDA) for this purpose. LDA, being one of the most prominent feature extraction techniques, ensures that the extracted features are not only distinct but also optimal for classification. The heart of the recognition system lies in its classification model. This research proposes a deep Convolutional Neural Network (CNN), renowned for its capacity to discern patterns and classify with astounding precision. The advantage of employing a deep CNN in this context is its capability to deliver high accuracy without necessitating extensive datasets. A notable outcome of this research is the exemplary recognition performance yielded by the deep CNN model. When tested on the SDUMLA-HMT finger vein dataset, the model achieved an accuracy of 99.65%. Meanwhile, on the UTFVP finger vein dataset, it further exceeded expectations with an accuracy rate of 99.72%. These results are a testament to the efficacy of the proposed model, underscoring the potency of using a 1-dimensional convolutional network combined with dense layers. Another significant contribution of this thesis is the amalgamation of LDA with the deep model. This fusion has demonstrated superior prowess, not just in terms of recognition accuracy, but also in training speed, ensuring a swift and efficient system. Lastly, to bridge the recognition system with the cloud database, the TCP/IP protocol is employed. This ensures that once an individual is recognized, their pertinent information can be swiftly retrieved from the cloud database. This integration not only augments the recognition system's functionality but also elevates its application potential in real-world scenarios.
