Abstract: The present invention relates to a folding structure comprising a storage device with an electronic component at least and a plurality of metal contacts and is configured with electronic component(s), metal contacts, and a plug board or a folding kit to embody the present invention's space effectively used and saved, match the present product's design requirements for lightness, thinness, shortness, and smallness, and integrate with other relevant products to become a combinational product with both multiple functions and its shape advantageous to lightness, thinness, shortness, and smallness.

Abstract: An encryption flash disk comprises a memory module, an encryption system, and a switch device wherein the memory module has a substrate accommodating an inner surface provided with a memory chip as well as a control device at least and a plurality of metal contacts; the encryption system is installed in the memory chip electrically connected to the control device and comprises a public zone and a private zone at least and a public program wherein the public program has a password configure module used to configure, input, and clear a password; the switch device is electrically connected to the memory module's control device. Accordingly, the encryption flash disk is capable of keeping digital data secret and safe.

Abstract: A combinative encryption flash disk with two data disks and an encryption system at least for digital data encrypted and accessed via an operating system is characteristic of (1) Function of keeping digital data secret and safe; (2) Consumer's reduced cost and a specific plug-in sequence for a promoted secrecy function by two cascaded data disks at least plugged into a single port; (3) Plain interface and simple operation in favor of one user configuring and operating.

Abstract: The present invention is one storage device for data share which comprises a device body with a USB communications interface unit, a memory unit, and a control unit wherein the memory unit has an executive file/program comprising a group management module used to manage a group/peer list and the group list has at least a group ID and a peer ID. Accordingly, the storage devices with the same group ID can be referred to as “peers” inside the group and mutually share files saved in respective storage devices when at least two storage devices with the same group ID are separately plugged onto computers and complete login on the central server via Internets.

Abstract: Disclosed is a cascaded combination structure of flash disks to create security function, comprising of a plurality of data disks and a key disk. Each of the data disks includes a public zone and a private zone matched with the key disk. When the key disk is series-connected with the data disks, the private zone can be displayed and load/save by a public program in the key disk. Accordingly, there can be secured and hid the data in the private zone so that the data in the private zone is unable to be embezzled by other illegal users.

Abstract: A method of utilizing USB record carriers is disclosed. A USB security drive is serially connected with at least a USB drive to encrypt/decrypt stored data in the USB drive and to integrate a plurality of data regions or even a plurality of encrypted data regions to provide multi-level security protections. In a more specific embodiment, the USB security drive further enables the automatic backup of data stored in the USB drive. A related assembled module by the implementation is also disclosed.
