  • Publication number: 20030101349
    Abstract: This invention represents a method of using cryptography with biometric verification on security authentication. The present invention relates to secure transmission of data or confidential information and, in particular, to cryptography technology that prevents the multiple passwords of keys lengthy, inconvenient and hard to be remembered or hidden. The method is used to perform security authentication by utilizing live biometric feature, which is non-transferable and unique among all humans, and operating the asymmetric key of cryptography technique for collation. Therefore, in the present invention, the method is capable of providing cryptography technology in conjunction with the biometric authorization to prevent that people don't like to carry private keys and using a single key only to perform authentication will reveal privacy or private information.

  • Patent number: 6571228
    Abstract: A method uses a hybrid neural network including a self organizing mapping neural network (SOM NN) and a, back-propagation neural network (BP NN) for color identification. In the method the red, green and blue (RGB) of color samples are input as features of training samples and are automatically classified by way of SOM NN. Afterwards, the outcomes of SOM NN are respectively delivered to various BP NN for further learning; and the map relationship of the input and the output defines the X,Y, Z corresponding the x, y and z values of a coordinate system of the standard color samples of RGB and IT8. By way of the above learning structure, a non-linear model of color identification can be set up. After color samples are self organized and classified by SOM NN network, data can be categorized in clusters as a result of characteristic difference thereof.

  • Publication number: 20030048904
    Abstract: This invention represents a Web-based biometric authorization apparatus. The present invention relates to live biometric characteristics which are captured by a biometric capture device and, in particular, to the Biometric Identification Record (BIR) and personal information which are stored in a digitized data storage apparatus. It is therefore an object of the present invention to provide the further data process which includes compression and decompression function, encryption and decryption function, and to provide the BIR process which relates to calculation, collation and verification as a secured mechanism. The apparatus is operatively coupled to a remote site so as to establish an Internet communication link through wired or wireless communications. Therefore, the biometric verification is performed with peripheral devices such as POS terminals, ATM terminals, credit card reader, access control or other control mechanism.

  • Publication number: 20030048175
    Abstract: This invention represents a portable biometric verification and storage device. The portable device performs the biometric characteristics recognition or verification for providing high security of personal identification by collating digital Biometric Identification Record (BIR) stored in the device and personal activated biometric characteristics. The Biometric Identification Record (BIR) includes a memory for storing at least one or more personal biometric characteristics database and for storing at least one or more ID of each person and personal information in a portable biometric verification and storage device.

  • Publication number: 20020163421
    Abstract: This invention represents a method of bank card and credit card with fingerprint authentication for identifying whether a user is a registered owner of the card. The reference fingerprint data will be digitized and stored in an IC chip or stored on a magnetic strip of a bank card and a credit card. Therefore, this invention can identify the correct user of the bank card or the credit card by collating the measured fingerprint data with the reference fingerprint data via a fingerprint ATM terminal or a fingerprint reading device of the credit card. It could prevent the illegal use of these cards and heavy financial problems of issuing banks.
