And delivery mode, it is usually directed to provide the most easily extension and the most virtualized money by internet
Source.Cloud is a kind of metaphor saying of network, internet.Past the most often represents telecommunications with cloud
Net, is the most also used for representing the abstract of internet and underlying infrastructure.Therefore, cloud computing even may be used
To allow you experience the operational capability of 10 TFlops per second, having the most powerful computing capability can be with mould
Nucleoid blast, Prediction of Climate Change and market trend.User passes through computer, notebook, mobile phone
Access data center etc. mode, carry out computing by the demand of oneself.
Definition to cloud computing has multiple saying.For what is cloud computing on earth, at least can find
100 kinds of explanations.Present stage is well accepted is that National Institute of Standards and Technology (NIST) is fixed
Justice: cloud computing is a kind of pattern paid by usage amount, this pattern provide available, easily,
On-demand network accesses, and (resource includes network, service to enter configurable computing resource sharing pond
Device, storage, application software, service), these resources can quickly be provided, and only need to put into seldom
Management work, or carry out little mutual with service supplier.Cloud computing starts to step into each
Important application.

Need all to launch infrared ray, relatively costly and poor feasibility from each position.Therefore on-the-spot electronics is prevented
The equipment of taking on the sly also needs to find other break through direction.
To this end, the present invention proposes the electronic equipment prevented taking on the sly in a kind of new scene, it is possible to by existing
In auditorium spectators behavioral value and by the parameter extraction of site environment is determined scene
Whether auditorium exists the person of taking on the sly, and can in time the position at the person of taking on the sly place be positioned, with
It is easy to take to orient warning measure accordingly, reminds the person of taking on the sly to abandon the behavior of taking on the sly.
