20140204543 | TAMPER PROTECTION DEVICE AND DATA TRANSACTION APPARATUS - A data transaction apparatus includes a housing, a system circuit board comprising a tamper detection circuit disposed in the housing, and a tamper protection device configured to seal the system circuit board within the housing in a detachable manner. The tamper protection device includes a tamper resistant board and a resin layer covering the tamper resistant board, wherein the tamper resistant board includes a flexible substrate and a plurality of fence-like lead wires disposed on the flexible substrate. In one embodiment of the present disclosure, the tamper detection circuit is triggered to generate a secure response when a tamper event is detected. | 07-24-2014 |
20120124378 | METHOD FOR PERSONAL IDENTITY AUTHENTICATION UTILIZING A PERSONAL CRYPTOGRAPHIC DEVICE - A method for personal identity authentication utilizing a personal cryptographic device initially provides a personal cryptographic device storing a client key from a host system and a device serial number. Next, the personal cryptographic device is connected to the host system. Thereafter, unique user information is inputted via the personal cryptographic device. Then, the unique user information and the device serial number are encrypted and sent to the host system for authentication and for requesting key information. The personal cryptographic device receives and decrypts encrypted key information with the client key, and changes the client key using the key information. | 05-17-2012 |
20120105258 | DATA ENTRY MODULE - A data entry module includes a flexible substrate, a fence circuit formed on the flexible substrate and including at least one trace routed in a meandering manner, an insulating layer formed on the fence circuit, a substrate spaced from the insulating layer, and a switch circuit including a plurality of switch elements each including two contact pads separately disposed on the substrate and the insulating layer. The fence circuit is configured to cover the switch circuit for preventing the interrogation of the switch circuit. | 05-03-2012 |
