20100171202Method of securely data protecting arrangement for electronic device - A method of securely data protection for an electronic device includes the steps of: enclosing a core circuit module of the electronic within a protection element to form a protection circuit surrounding the core circuit module; operatively linking a detective circuit between the protection element and the core circuit module; and activating the detective circuit in case of a hack of the electronic device, such that when the electronic device is broken to access the core circuit module through the protection element, the detective circuit is activated to block data information saved in the core circuit module from being access.07-08-2010
20100172501Secure key system - A secure key system includes a key provider for partitioning and converting a private key into a plurality of key components, and a plurality of key holders storing the key components therein respectively for enhancing a security level of the private key, wherein all of the key holders are united to synthesize back the private key from the key components in order for completing a confirmation process so as to ensure the confirmation process being verified by all of the key holders.07-08-2010
20100172655NON-FEEDBACK PRE-ENCODER FOR OPTICAL DQPSK MODULATION - A non-feedback pre-encoder for optical DQPSK modulation includes four differential encoders, two power splitters, two delay lines, one exclusive OR gate and a cross switch. Each of two data streams input to the pre-encoder is divided into two identical streams by one of the power splitter, called an upper stream and a lower stream, respectively. Every upper stream is differentially encoded by one of the differential encoders, and outputs of the differential encoders are fed into the XOR gate. An output of the XOR gate drives the cross switch as a control signal. Two lower input data stream are delayed in the delay lines, and fed into the cross switch. The outputs of the cross switch are differentially encoded, separately, where outputs of the pre-encoder are provided. The invention eliminates the speed limitation due to the electrical propagation by constructing an all-forward control signal.07-08-2010
20100174631Secure device firmware - The present invention provides a method and a device using a secure firmware for secure electronic transactions. This firmware realizes two main functions: (1) providing protection for transaction, and (2) providing a unified standard interface for application programs.07-08-2010
20100174653Secure method and device of financial transaction - A secure method and device thereof is provided for financial transaction without being access of any personal and confidential transaction information by any unwanted party, which includes the following steps. Receive transaction information and personal information of a user in a secure financial transaction device. Encrypt the transaction information, the personal information and a secure PIN of the user in the device and transfer the encrypted transaction information, personal information and the secure PIN to a designate financial entity through the Internet. Verify a payment amount to a designated financial account with the financial entity. Receive a confirmation in the device for the transaction of the payment amount to the designated financial account, after the payment amount is transferred to the designated financial account from the financial entity, by the financial entity through the Internet.07-08-2010
20100175016Security key inputting system for touch screen device - A touch screen device includes a touch screen panel having a key input area and defining a plurality of touch-sensitive keys at the key input area, a control module operatively linking with the touch screen panel, and a security key inputting system operatively linked to the control module. The control module displays a plurality of input characters at the touch-sensitive keys respectively in such a manner that when one of the touch-sensitive keys is contacted, the control module identifies the corresponding input character being selected as an input data. The security key inputting system is arranged for randomly re-arranging the input characters at different touch-sensitive keys respectively, wherein the input characters are alternately displayed at the touch-sensitive keys for preventing the input characters from being read by memorization of fixed location.07-08-2010
20110095084Personal financial terminal device - A personal financial terminal device includes a core circuit module having a CPU and a data unit electrically connected to the CPU, a display module operatively connected to the core circuit module, and a protection arrangement for protecting the security data information store in the core circuit module. A swipe slot, an inserting slot, and a USB port are further provided at a peripheral edge of an outer casing, so that the terminal device of the present invention is able to obtain information stored in a magnetic strip card, smart card, or via connecting to an external device respectively. Therefore, the personal financial terminal device is able to integrate with most of the existing financial transaction networks or platforms to complete the individual business transactions.04-28-2011
