July 1, 2014



By a News Reporter-Staff News Editor at Information Technology Newsweekly -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventors LU, Shih-Yu (Nantou County, TW); LU, Hsin-Tse (Taipei City, TW), filed on March 5, 2013, was made available online on June 19, 2014.

The assignee for this patent application is Institute For Information Industry.

Reporters obtained the following quote from the background information supplied by the inventors: "The embodiment of the present invention relates generally to a synchronization system and method thereof and, more particularly, to a data synchronization system and a method for synchronizing data.

"The idea of cloud computation progresses with the development of science and technology. Under the application of cloud computation, users are allowed to store their data in a remote storage device and use the communication between an electronic device and the storage device to access the data.

"Generally, if a user intends to compute the data stored in the remote device using the electronic device, the user must synchronize the data to the electronic device, before the computation starts. In this scenario, the data synchronization process or the download of data from the cloud storage device to the electronic device would cost substantial time for data transfer.

"Further, if multiple users use the same virtual machines, when one of the multiple users logs in, said user would not necessarily be designated the same virtual machine that he/she used during his/her previous log-in. In this case, the user would not immediately have access to his/her data during the current log-in.

"Many efforts have been devoted trying to find a solution of the aforementioned problems. Nonetheless, there still a need to improve the existing apparatus and techniques in the art."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "One purpose of the present invention is to provide a data synchronization system and a method for synchronizing data, so as to address the problems associated with existing data synchronization systems.

"To this purpose, on aspect of the present invention is directed to a data synchronization system which comprises a database, a management device and a synchronization device. Further, the database comprises a plurality of user folders, and the management device comprises an authentication module and data storage module. Structurally, the management device is communicatively connected to the database, and the synchronization device is communicatively connected to the management device. Specifically, the authentication module is communicatively connected to a client terminal device, and the data storage module is communicatively connected to the authentication module.

"In operation, the authentication module is configured to authenticate the identification of the user who uses a client terminal device to log in the authentication module and output an authentication signal based on the result of the identification. The data storing module is configured to receive the authentication signal and output an index signal based on the authentication signal. The client terminal device is configured to connect to a corresponding user folder based on the index signal, and the corresponding user folder is used as a major user folder. The synchronization device is configured to log in one of accounts of a commercial database and synchronize the data of the account to the major user folder. The client terminal device is configured to connect to a corresponding user folder based on the index signal, and the corresponding user folder is used as a major user folder. The synchronization device is configured to log in one of the accounts of a commercial database and synchronize the data of the account to the major user folder.

"According to one embodiment of the present invention, the data synchronization system further comprises a hypervisor which is communicatively connected between the database and the management device. The hypervisor has a plurality of virtual machines installed therein, and is configured to retrieve the data from the major user folder based on the index signal.

"According to another embodiment of the present invention, the management device further comprises a virtual machine management module which is communicatively connected to the authentication module. The virtual machine management module is configured to provide an operating-system (OS) selection interface, and outputs a selection signal based on an OS selection result. The hypervisor receives the OS selection signal such that the client terminal device is operated in the corresponding operating system.

"According to yet another embodiment of the present invention, the synchronization device is continuously in communication with the commercial database.

"According to still another embodiment of the present invention, the synchronization device continuously synchronizes the data of the account to the major user folder.

"To achieve the above-mentioned purpose of the present invention, another aspect of the present invention is directed to a method for synchronizing data which is used in a data synchronization system. Said data synchronization device comprises a database, a management device and a synchronization device, in which the management device is communicatively connected to the database, and the synchronization device is communicatively connected to the management device. Said method for synchronizing data comprises the following steps:

"using the management device to authenticate the identity of a user who uses a client terminal device to log in the management device;

"using the management device to output an authentication signal based on the result of the authentication;

"using the management device to receive the authentication signal and output an index signal based on the authentication signal;

"the client terminal device connecting to a corresponding user folder in the database based on the index signal, such that the corresponding user folder serves as a major user folder; and

"using the synchronization device to log in one of the accounts of a commercial database based on the authentication signal, and synchronize the data of the account to the major virtual machine.

"According to one embodiment of the present invention, the data synchronization system further comprises a hypervisor that is communicatively connected between the database and the management device. The method for synchronizing data further comprises using the hypervisor to retrieve the data from the major user folder based on the index signal.

"According to another embodiment of the present invention, the method for synchronizing data further comprises the following steps;

"providing an operating-system (OS) selection interface;

"outputting a selection signal based on an OS selection result; and

"using the hypervisor to receive the OS selection signal such that the client terminal device is operated in the corresponding operating system.

"According to yet another embodiment of the present invention, the synchronization device is continuously in communication with the commercial database.

"According to still another embodiment of the present invention, the synchronization device continuously synchronizes the data of the account to the major user folder.

"In view of the foregoing summary of the present disclosure, embodiments of the present invention provides a data synchronization device and a method for synchronizing data so as to address the problems associated with existing data synchronization system; said problems, for example, include the waste of substantial time for the data synchronization or downloading data from the cloud storage device to the electronic device.
