A New Palm Print Recognition Approach by Using PCA & Gabor Filter
The key problems that involve in identification of palm print are searching for the better match from the test sample taken from input and also the available templates in the palm print database. The selection of the features and measuring similarity are 2 basic to be resolved. A feature that has higher discriminating ability should need to show a large variation between samples taken from totally different persons and small variation between samples taken from the palm of same person. Principal lines with information points are consider as very helpful palm print features and are successfully used for the aim of verification. Excluding these features there are many various features present in a palm print like: wrinkle features, geometry features, minutiae features and delta point features. It�s noted that each one of those features of palm are involved with the native attributes supported points or line segments. 2 key points in palm print identification are: first is to develop an efficient algorithm that extracts helpful features and second is to correctly measure the similarity of 2 features sets. In contrast to the existing technique, propose a combine selection technique for identification by using the palm print feature base pattern matching by combining native and global palm print features in some stratified fashion. In this work, use PCA, Gabor Filter and KNN for the aim of classification and matching. This work show palm print authentication system operates in 2 ways in which first is enrolment and the second is verification. In enrolment, a user needs to offer palm print samples many times to the system. The samples is captured with the use of any image capturing device that then pre-processed and so extraction of features is done to provide the templates that keep template database. For verification user is instruct to produce his/her user ID and palm print sample, then the palm print sample are pre-processed and extraction of feature is done to compared it with templates keep within the database that belonging to constant user ID
The Ethical Implications of Personal Health Monitoring
Personal Health Monitoring (PHM) uses electronic devices which monitor and record health-related data outside a hospital, usually within the home. This paper examines the ethical issues raised by PHM. Eight themes describing the ethical implications of PHM are identified through a review of 68 academic articles concerning PHM. The identified themes include privacy, autonomy, obtrusiveness and visibility, stigma and identity, medicalisation, social isolation, delivery of care, and safety and technological need. The issues around each of these are discussed. The system / lifeworld perspective of Habermas is applied to develop an understanding of the role of PHMs as mediators of communication between the institutional and the domestic environment. Furthermore, links are established between the ethical issues to demonstrate that the ethics of PHM involves a complex network of ethical interactions. The paper extends the discussion of the critical effect PHMs have on the patient’s identity and concludes that a holistic understanding of the ethical issues surrounding PHMs will help both researchers and practitioners in developing effective PHM implementations
Development of CUiris: A Dark-Skinned African Iris Dataset for Enhancement of Image Analysis and Robust Personal Recognition
Iris recognition algorithms, especially with the
emergence of large-scale iris-based identification systems, must
be tested for speed and accuracy and evaluated with a wide
range of templates – large size, long-range, visible and different
origins. This paper presents the acquisition of eye-iris images
of dark-skinned subjects in Africa, a predominant case of verydark-
brown iris images, under near-infrared illumination. The
peculiarity of these iris images is highlighted from the
histogram and normal probability distribution of their
grayscale image entropy (GiE) values, in comparison to Asian
and Caucasian iris images. The acquisition of eye-images for
the African iris dataset is ongoing and will be made publiclyavailable
as soon as it is sufficiently populated
Multimodal Biometrics Enhancement Recognition System based on Fusion of Fingerprint and PalmPrint: A Review
This article is an overview of a current multimodal biometrics research based on fingerprint and palm-print. It explains the pervious study for each modal separately and its fusion technique with another biometric modal. The basic biometric system consists of four stages: firstly, the sensor which is used for enrolmen

A Survey Paper on Palm Prints Based Biometric Authentication System
In this paper we are providing an approach for authentication using palm prints. Reliability in computer aided personal authentication is becoming increasingly important in the information-based world, for effective security system. Biometrics is physiological characteristics of human beings, unique for every individual that are usually time invariant and easy to acquire. Palm print is one of the relatively new physiological biometrics due to its stable and unique characteristics. The rich information of palm print offers one of the powerful means in personal recognition
