摘要： Methods and apparatus are provided for authenticating communications between a user computer and a server via a data communications network. A security device has memory containing security data, and security logic to use the security data to generate an authentication response to an authentication message received from the server in use. An interface device communicates with the security device. The interface device has a receiver for receiving from the user computer an authentication output containing the authentication message sent by the server to the user computer in use, and interface logic adapted to extract the authentication message from the authentication output and to send the authentication message to the security device. Includes a communications interface for connecting to the server via a communications channel bypassing the user computer. Either the security device or interface device sends the authentication response to the server via the communications channel bypassing the user computer.

摘要： Techniques for decoding a multi-modal barcode are provided. The techniques include scanning a multi-modal barcode into a grayscale image, applying a threshold to quantize the grayscale image into a monochrome image, passing the monochrome image to 1D barcode recovery to reconstruct a primary barcode, applying a horizontally-oriented edge detector to the grayscale image to quantize grayscale into monochrome, passing the monochrome image to a 1D barcode recovery process to reconstruct a secondary barcode to decode the multi-modal barcode.

摘要： A method of decoding a two-dimensional enhanced-density barcode. A first and a second barcode are encoded in the enhanced-density barcode. The enhanced-density barcode includes a set of blocks. Each block includes a predefined number of sub-pixels. The blocks of the enhanced-density barcode being arranged relatively to each other in a geometrical lattice having a first and a second lattice direction. The method includes the steps of distorting of the enhanced-density barcode in the first lattice direction, resulting in a first distorted barcode, distorting of the enhanced-density barcode in the second lattice direction, resulting in a second distorted barcode, reconstructing the first barcode by low-pass filtering the first distorted barcode, reconstructing the second barcode by low-pass filtering the second distorted barcode.
