Recently, extensive research and development have been done in the area of computer including both hardware and software. However, software piracy has become a major issue which software developers have to face and fight with.When the attacker has full control over the environment running the software, he can inspect and modify the software at will.

Virtualization, which is an old and important technique in computer field, has regained widespread attention in recent years. Using virtualization method can not only help corporations reduce the costs of the construction of distributed systems greatly, but also optimize various factors such as efficiency, availability, convenience and security. In addition, virtualization is also considered as

Live forensic is becoming one significant part in modern digital investigation. It is effective in obtaining criminal evidence which only exists in memory. Unfortunately, current efforts either fail to provide accurate acquisition of native system state at the given time point or require suspending the machine and altering the execution environment drastically.To address this issue,
