BACKGROUND Human genetic diversity observed in Indian subcontinent is second only to that of Africa. This implies an early settlement and demographic growth soon after the first 'Out-of-Africa' dispersal of anatomically modern humans in Late Pleistocene. In contrast to this perspective, linguistic diversity in India has been thought to derive from more(More)
In this paper, we propose a new signature scheme based on factoring and discrete logarithm. This scheme is based on two hard problems and provides higher level security as compare to a single hard problem. Most of the designated signature schemes are based on a single hard problem. Although these schemes secure but in a future if an enemy manages to solve(More)
Phonocardiogram (PCG) signals as a biometric is a new and novel method for user identification. This paper examines the applicability of the biometric properties of PCG signals, which can thus be included among the physiological signs used by an automatic identification system. Use of PCG signals for user recognition is a highly reliable method because(More)
— In the digital world, security is an important issue, and encryption is one of the ways to ensure security. This paper presents image encryption/decryption scheme using biometric template (Palm Print). The proposed scheme is especially useful for encryption of large amounts of data, such as digital images using proposed key generation algorithm. This(More)
In 1994, He and Kiesler proposed a digital signature scheme which was based on the factoring and the discrete logarithm problem both. Same year, Shimin-Wei modified the He-Kiesler signature scheme. In this paper, we propose an improvement of Shimin-Wei signature scheme based on factorization and discrete logarithm problem both with different parameters and(More)
Online political portals contain a huge volume of users' comments. These comments express whether writer's attitude is positive, negative, or neutral towards the subject. In most of the comments, we find that there are suggestions or feedback also hidden along with the opinion. These suggestions or feedbacks from the mind of different people on various(More)
A simple theoretical model is developed to study the high pressure behavior of solids and is applied to evaluate the pressure for MgO in case of large compression along with Shanker, Tait, Vinet, and Birch-Murnaghan equation of states (EOSs). These EOSs are also tested for the basic requirements revealed from the fundamental thermodynamics for solids in the(More)
These days technical education is spreading all over the world (rural as well as urban areas) very rapidly and gradually application of ERP system in technical institutes is becoming common. But with very fast changing technology there is a continued need to enhance the efficiency of operations in ERP system as problems regarding decision making process are(More)
