Research on the two-way defense model of large data dynamic security SAT

To guarantee the safety of big data calculation, the concept of security research and trusted cloud combined with large data security, a two-way defense system model of a large data calculation of SAT. The model of user data evidence through the dynamic safety factor; gradually determine the behavior of security permissions according to the reliability test implementation behavior. Provide the maximum-security defense for users. the experimental results show that the model can effectively improve the data big data security, reduce malicious hackers, to improve the efficiency of data analysis.

Comparison of Windows Phone 8 & Windows 8

Operating system platform of the intelligent equipment of current mainstream and traditional PC gradually evolved into Windows, IOS and Android camps. Among intelligent equipment, Android & IOS due to openess and flexibility got the initiative, while Windows has been in worse situation. But with the Microsoft Windows 8 & Windows phone 8, the pattern of the future may change dramatically. Microsoft is expecting a dominant position in this intelligent device operating system competition via announcing these new members. Nokia hopes Windows system could bring it back to its glorious. The thesis conducted a detailed comparison on these two brand new operating systems, and tried to find their superiority in the application of intelligent equipment. At the same time, author wish could help to clarify the direction for both companies on operating system in this more and more serious ecological environment competition.

Research on technology of multi-view stereo video display based on optical-plate stereo mobile phone

This paper is on the multi-view stereo video display system on mobile phone. The key point is that the existing eight viewpoints display technology on optical-plate stereo mobile phone has an obvious but not very clear stereoscopic effect. Firstly, this paper does some research on parallax principle parallax corrector method and the viewpoints matching principle based on the multi-view image composition method. Secondly, proposes two resolutions: viewpoints adjustment and numbers of viewpoints reduction. Finally, gives the combination method about the two resolutions. The experiments conclude that these two resolutions proposed by this paper can ensure the stereo display effect, and greatly improves the stereo display clarity.

The method of multi-view adaptive display on optical-plate stereo mobile phone

As the maximum of viewpoint in each optical-plate unit attached with the mobile phone is fixed, when the bandwidth of wireless network is insufficient, the data of videos with the maximum viewpoints will not be transferred perfectly. The multi-view adaptive display method on optical-plate stereo mobile phone can increase or decrease the multi-view stereo videos according to the network bandwidth, transfer the data of stereo videos as many as possible and re-arrangement pixels of received stereo videos on the stereo mobile phone. Experimental results indicate that the proposed method can fully utilize the network bandwidth and maintain the display stereoscopy and clarity of multi-view stereo videos, which is very important to real-time transfer and display multi-view stereo videos.
