-This paper propose a virtual network computing (VNC) based architecture for accessing the desktops of remote computers from a cellular phone. A viewer is provided on the cellular phone that enables the user to see and manipulate the desktop of various remote systems such as MS Windows, Macintosh, and UNIX. The system to be accessed must be running a VNC server and it must be attached to a network. A proxy is used to send the image of the desktop to the cellular phone, to convert different devices, to suppress network traffics, and to support recovery from an unscheduled disconnection. To reduce user effort and solve problems inherent to the cellular phone"s small screen, several functions are provided on the cellular viewer. Frequently used screen areas can be assigned and restored quickly by using the Shortcut function. The Guidance function can be used to show the current key assignments. Two areas can be viewed at the same time by the Twin view function. In this paper a prototype of the proposed architecture has been implemented using Java and has been tested on a Java-enabled cellular phone emulator.

Majority of data owners have moved their services to the cloud servers. Members of any organization can access data from the cloud by using keyword-based search. Being based on Boolean keyword matching system or semantic search they are unable to provide accurate search results as well as unable to understand misspelled keywords. With the existing searching mechanisms like keyword search in place, the search results are often slow and they result in missing of information and produce in accurate results. In this paper, a K-Gram based approach is proposed to improve the search efficiency. Using this approach, the words are divided in to groups and then they are identified by the corresponding Indexes. This proposed approach can improvise secure and efficient retrieval of information.
