Abstract: A femtocell, a femtocell gateway and an access rejection method thereof are provided. A wireless network system comprises a wireless device, a plurality of the femtocells, the femtocell gateway and a core network server. The wireless device has a Subscriber Identification and the core network server stores a Closed Subscribers Group Identification of the femtocells. The femtocell gateway receives an access rejection message corresponding to the Subscriber Identification of the wireless device from the core network server, and transmits the access rejection message to the femtocells. Each femtocell records the Subscriber Identification in a rejection list thereof, and it is capable of adding/deleting Subscriber Identifications in its rejection list.

Abstract: The present disclosure relates to a Completely Automated Public Turing Test to tell Computers and Humans Apart (CAPTCHA) image authentication method and system. The CAPTCHA image authentication method comprises the steps of: collecting a plurality of first objects; defining a plurality of variables so as to be used as basis for classifying and dividing the plural first objects into M groups accordingly while allowing each group in the M groups to correspond to at least one variable selected from the plural variables; selecting at least one group from the M groups while further grading and dividing the first objects in the selected group into subgroups of N grades based upon a standard unit of the variable corresponding to the selected group; sorting and storing the subgroups of N grades; and selecting a plurality of authentication objects from the subgroups of N grades to be used in an authentication process.

Abstract: The present invention discloses an electronic device, a cloud storage system, a method thereof and a tangible embodied computer readable medium. The cloud storage system comprises at least one server and an electronic device. The at least one server provides a plurality of cloud storage spaces for accessing data. The electronic device comprises a storage management interface and is connected to each of the servers via Internet in order to access the cloud storage space. Wherein, the cloud storage spaces are integrated as a virtual storage space by the electronic device for a user to access data therefrom. The user can concurrently access the cloud storage spaces through the storage management interface of the electronic device, or access one of the cloud storage spaces by multi-thread or multi-process so as to raise the access speed.
