In this paper, we propose some specific methods in popular network scenarios and show that these generic methods can be combined together when it is necessary to adapt to different requirements of digital forensics in various scenarios. We also perform some analysis of digital forensics in different contexts and provide solutions to solve the problems that come along.
With the development of the vehicle electronic and information technology, the police need collecting more and more electronic evidence during handling traffic accidents. How to effectively use electronic data for traffic accident treatment service has been a new problem in our work. On the basis of the introduction of related concepts and research of the present situations, this paper introduces...
The fast development of internet application is boosting the development of cloud computing, a new paradigm of provisioning computing infrastructure and services over network. In cloud computing environment, MapReduce is often used to perform scientific computing like matrix multiplication and do data mining and information extraction on massive data. Hadoop, an open-source implementation of MapReduce,...
AS well as in real physical environment, time subsystem is also a vital part in the distributed virtual environment. DVMM, based on multi-nodes and achieves single system image, has faced with the challenge of the time accuracy. High Precision Event Timers which is broad supported in current Linux kernel as a system clock source and can even be used to replace of PIT and TSC, can improve the accuracy...
Backup technology based on data de-duplication has become a hot topic in nowadays. In order to get a better performance, traditional research is mainly focused on decreasing the disk access time. In this paper, we consider computing complexity problem in data de-duplication system, and try to improve system performance by reducing computing time. We put computing tasks on commodity coprocessor to...
