With recent revolutions in sensor and actuator technologies, availability of powerful but inexpensive embedded computing and introduction of new multi-hop wireless network standards for industrial automation, control over wireless networks is becoming a disruptive technology. Traditional wired interconnections between the plant sensors, controllers and actuators can be replaced by wireless multi-hop mesh networks, yielding cost […]
The Sequence of Operations In Credit Card Transaction Processing
They proposed credit card fraud detection with a neural network. They have built detection system, which is trained on a large sample of labeled credit card account transactions. These transactions contain example fraud cases due to lost cards, stolen cards, application fraud, counterfeit fraud, mail-order fraud, and non received issue (NRI) fraud. suggest a credit […]
Multiple-input-multiple-output (MIMO) wireless systems
Increasing demand for high-speed wireless networks has motivated the development of wireless ad-hoc networks. In order to fully exploit the technological development in radio hardware and integrated circuits, which allow for implementation of more complicated communication schemes, the fundamental performance limits of wireless networks should be reevaluated. In this context, the distinct characteristics of wireless […]
Two server password only Authentication and key exchange
Nowdays, passwords are commonly used by people during a log in process that controls access to protected computer operating systems, mobile phones, cable TV decoders, automated teller machines and so on. A computer user may require passwords for many purposes: logging in to computer accounts, retrieving e-mail from servers, accessing programs, databases, networks, web sites, […]
The Basis Of Information Entropy
The current state of the art of privacy-preserving techniques in participatory sensing. The first implementation of a privacy aware architecture, named Anony Sense, for the anonymous task allocation and data reporting. From the perspective of cryptography, analyzed the realistic architectural assumptions and privacy requirements, and then provided an instantiation that achieved privacy protection in participatory […]
Multi message dissemination over static and Mobile networks
A simple distributed gossip-style protocol that achieves near-optimal spreading rate for multimessage dissemination, with the assistance of mobility. The key observation is that random gossiping over static geometric graphs is inherently constrained by the expansion property of the underlying graph – capacity loss occurs since the copies are spatially constrained instead of being spread out. […]
