“…CCD camera captures a top-view finger image while the user is touching a fingerprint sensor, and the acquired gray scale image is preprocessed to enhance the edges, the skin furrows, and the nail shape before a bank of oriented-filters filters the image. A square tessellation is applied to create a feature map, called a Nail Code [7], employed in the matching process by employing a Euclidean distance computation. It is in conjunction with fingerprint for multimodal biometric identification accuracy.…”

Digital image processing plays a key role in medical imaging. Nail diagnosis is one of the methods in Ayurveda, Homeopathy and traditional medicines to predict the diseases. Nails can reflect the present health condition, genetically inheritance information, and historical information of drug or alcohol usage for the past months or even a year, etc. This paper explores the existing research works related to nail plate and nail matrix as tool for bio-metric system, nail fold capillaries to identify the disease severity levels & affected organs, nail surface as evidence in forensic science to identify the chemical effects, nail samples to identify drug intake and abuse etc. So that, Nail is analyzed by various imaging types and processing algorithms to recognize the person's uniqueness, health condition and its history. This paper also identifies the research challenges and issues. Keywords-Finger nail analysis; abnormalities of nails; nailfold capillaroscopy NFC; nail disease prediction; nails in forensic sciences;nails in bio-metric recognition systems.I.

“…The abnormalities are the clues for common medical problems or severe systemic diseases. Nail diagnosis is a method to predict the diseases, infections by analyzing capillaries appearance, microcirculations and hemorrhages under the nail plate [7]. Nail can be an additional tool for personal identification in biometric recognition systems.…”

“…Any change in the color or size of the lunula may reflect the unhealthiness of the body. Chaikan and Karnjanadecha 1 propose a nail diagnostic system, as well as methods of predicting disease and infection through the analysis of the appearance of blood capillary, microcirculations, and hemorrhages under the nail plate. Devi and Banu 2 sort out the related research work of nails in recent years, and the methods used include image contrast adjustment and magnification, 3 feature measurement, 4 image enhancement, 4 Laplacian skeleton algorithm, 5 and skeleton and binary algorithms.…”

In traditional Chinese medicine, the growth situation of the surface of nails reflects the physiological condition of the human body. Diagnosis by nail can effectively predict and prevent disease. Human nails have a high degree of uniqueness, and it can be used for biometric recognition. In this work, microscope sensor was used to capture the clear image and segment the lunula and nail plate effectively through image preprocessing. Fingernails' image is managed as the identity authentication. Histogram of oriented gradients and local binary patterns are used to capture the characteristic value. It uses support vector machine and random forest tree for classification. The performance of each feature extraction algorithm was analyzed for the two classifiers and the deep neural network algorithm was used comparatively. Furthermore, the security and privacy of the Internet of Things is still a challenge. This work uses the highly anonymous blockchain technology to effectively protect data privacy and manage each user's data through the blockchain, in which any change or manipulation can be recorded and tracked, and the data security is improved. Therefore, this article presents a nail analysis management system with the use of microscopy sensor and blockchain.
