—The Internet is a ubiquitous and affordable communications network suited for e-commerce and medical image communications. Security has become a major issue as data communication channels can be intruded by intruders during transmission. Though, different methods have been proposed and used to protect the transmission of data from illegal and unauthorized(More)
Secure transmission of message was the concern of early men. Several techniques have been developed ever since to assure that the message is understandable only by the sender and the receiver while it would be meaningless to others. In this century, cryptography has gained much significance. This paper proposes a scheme to generate a Dynamic Key-dependent(More)
A major area of current research in data mining is the field of medical diagnosis. In the present study using the Breast cancer Wisconsin data sets, a feature selection algorithm Modified Correlation Rough Set Feature Selection (MCRSFS) predicts both diagnosis and prognosis by comparing several data mining classification algorithms. In the proposed(More)
Feature selection aims to select subset of original features. It removes unrelated, redundant or noisy data from the problem domain. Rough set theory is often applied to feature reduction using the data alone, requiring no additional information and widely used for classification tool in data mining. Clustering, a form of data grouping, groups a set of data(More)
Feature selection is a fundamental problem in data mining, especially for high level dimensional datasets. Feature selection is a process commonly used in machine learning, wherein subsets of the features from the original set of features are selected for application of a learning algorithm. The best subset contains the minimum number of dimensions(More)
Iris recognition is the most accurate means of personnel identification due to the uniqueness of the patterns contained in each iris. The proposed technique uses the principle of the method proposed by Masek [4] to normalize the iris region. Libor Masek used a rectangular representation of the iris generated from a uniform selection of points along the(More)
With the rapidly changing technological realm, modern healthcare management systems need to change to accommodate these new advances. There is an urgent need to provide and protect the confidentiality of health care records when stored in common databases and transmitted over public insecure channel. This paper outlines DNA sequence based cryptography which(More)
As long as human beings exist on this earth, there will be confidential images intended for limited audience. These images have to be transmitted in such a way that no unauthorized person gets knowledge of them. DNA sequences play a vital role in modern cryptography and DNA sequence based cryptography renders a helping hand for transmission of such(More)
