Abstract: Disclosed is a document production and processing system, comprising a document input device, a document editing device, a document storage device, a biometric feature input device and a biometric feature matching device. The document edition device obtains, before a document is edited, first biometric feature file from the document and requests second biometric feature file from a user. Unless the first and second biometric features are matched, the user is not allowed to access the document.

Abstract: A fingerprint lock system includes a key device and a lock device. The key device includes a communication and power transmitting module, a fingerprint sensing module, and a battery. The fingerprint sensing module senses a fingerprint input and accordingly generates fingerprint data. The communication and power transmitting module outputs the fingerprint data and a supplying power. The lock device includes a communication and power receiving module, a storage module, and a processing module. The communication and power receiving module receives the fingerprint data and the supplying power from the key device to supply the storage module and the processing module with the supplying power. The storage module stores verification data. Each verification data includes minutiae features corresponding to a fingerprint. The processing module verifies if the fingerprint data has the minutiae features corresponding to the fingerprint and, if so, performs an unlock operation.

Abstract: A free wheel mechanism includes a basic assembly, a fastening member, a sleeve, a rotating member, a first elastic member, and a second elastic member. The basic assembly comprises a base, a guiding rod, and a free wheel. A guiding hole is defined in the fastening member to receive the guiding rod. One end of the sleeve is received in the guiding hole. The rotating member is positioned in a through hole of the sleeve. The first elastic member is coiled around the guiding rod, and opposite sides of the first elastic member resist against the base and the sleeve on opposite sides. The second elastic member is received in the through hole, and opposite sides of the second elastic member elastically abuts the rotating member and the guiding rod on opposite sides. Meanwhile, a moving apparatus with the free wheel mechanism is provided.

Abstract: A fingerprint feature identification system and method utilizes multiple feature points on a fingerprint to build feature triangles. Each of the feature triangles are classified as one of predetermined triangle classifications according to geometric data thereof. Every new feature triangle built from a new fingerprint is classified first and then compared with its geometric data to multiple filed feature triangles with the same triangle classification to shorten overall comparison duration.

Abstract: An amplitude shifted information embedding and detection method based upon the phase equalization is disclosed. It utilizes an equalization function to perform equalization computations on the DCT coefficients of an image. Through pixel shift, the original DCT coefficients have energy changes. Such changes are used to generate a visually compatible image with keys embedded at the same time. The information embedded image is very robust in the sense that the key information can still be accurately restored without comparing with the original image even if it is destroyed.

Abstract: A disk anti-copy system. An encrypted anti-copy mechanism with a device key table (Kd Table) prepared in a device and a fixed encryption processed media key block (MKB) pre-recorded in a disk is established. Only through the appropriate fixed encryption process between the key and the MKB can the device correctly read the disk. This controls the device and prevents disks from being copied. Moreover, the invention provides a method and device for preventing disks from being copied.

Abstract: A novel control system for image input device, especially fingerprint image input device, is disclosed. The control system comprises a fingerprint image input device selection module, an instruction conversion module and a fingerprint image size determination module. The fingerprint image input device selection module selects a particular fingerprint image input device from a variety of fingerprint image input devices. The instruction conversion module generates, upon an image capture instruction or a match instruction from a fingerprint verification software, particular image capture instructions to a the selected fingerprint image input device, wherein the instruction pertains to a specification of image as selected by a user or determined with a particular method. The fingerprint image size determination module determines the specification, including the resolution and the size of fingerprint image to be captured.

Abstract: A watermarking method and device to embed a digitized watermark into a digital image file in the transformation domain is disclosed. In the watermarking technology of this invention, the digitized watermark is first error corrected to enhance its robustness. The digital image file to be embedded with the digitized watermark is first processed such that capacity of each element of the digital image file is calculated. The capacity of an element of the digital image file represents the highest value of tolerance for an element of the watermark to be added to the said element of the digital image file. Elements of the digital image file to which watermark elements may be added are selected and their addresses are recorded. The selected elements are then modulated so that they are suited to be embedded with elements of the digital watermark. After modulation the digitized watermark is embedded into the digital file by distributing the modulated elements of the watermark into the selected addresses.

Abstract: A method for determining whether a pixel of a digitized image is a background or object pixel includes the steps of determining whether the pixel is in a static state or a transient state according to the variation in its gray-level compared with the gray-level of an adjacent pixel located in a first direction, setting a static threshold if the pixel is in the static state or a dynamic threshold if the pixel is in the transient state, comparing the gray-level of the pixel and the applicable threshold to determine whether the pixel is a background or object pixel, and repeating the determination with respect to static or dynamic thresholds, as applicable, in a second direction.
