    摘要: Methods, systems, and apparatus for accurately authenticating a document (e.g. a credit card) having a magnetic stripe are provided. The magnetic field at different points of the magnetic stripe are measured, e.g., by a checkout scanner to create a magnetic signature. Digital samples of the measurements may be used to create a representation of the magnetic signature. The representation can then be compared to reference values to produce a measure of the authenticity of the document. The reference values are updated over time to reflect changes in the magnetic stripe of the authentic document, as may occur due to physical deterioration. For example, reference values may be optimized based on recent measurements of the authenticated document to provide a more accurate determination of authenticity for future measurements.

    摘要: Methods, systems, and apparatus for verifying the identity of a cardholder are provided. A digital representation of a magnetic characteristic of a magnetic stripe of the card is stored on a portable electronic device of the cardholder. During a transaction, the digital signature is then transmitted so that it can be compared with a reference signature. The identity may be verified, and a response sent to a party requesting the verification, e.g., during a transaction between the requesting party and the verified party.

    摘要: A method for verifying a portable consumer device. The method includes receiving an authorization request message associated with a transaction conducted using a portable consumer device. The portable consumer device includes a portable consumer device fingerprint. The authorization request message includes an altered portable consumer device fingerprint and an algorithm identifier. The method also includes selecting an algorithm from among a plurality of algorithms using the algorithm identifier, determining the portable consumer device fingerprint using selected algorithm and the altered portable consumer device fingerprint, determining if the portable consumer device fingerprint matches a stored portable consumer device fingerprint, and sending an authorization response message after determining if the portable consumer device fingerprint matches the stored portable consumer device fingerprint.

    摘要: Methods, systems, and apparatus for efficiently authenticating a document (e.g. a credit card) having a magnetic stripe are provided. The magnetic field at different points of the magnetic stripe are measured, e.g., by a checkout scanner to create a magnetic signature. Digital samples of the measurements may be transformed into coefficients of continuous basis functions, e.g., a Fourier transform. These coefficients are then compared to reference values (e.g. corresponding coefficients) to produce a measure of the authenticity of the document. The number of coefficients used can advantageously be smaller than the number of digital samples without compromising accuracy, thus using less bandwidth between a scanner and an authentication entity.

    摘要: A method for forming a dynamic verification value. The method includes altering a first data string to form a second data string, and forming a first dynamic verification value using at least a portion of the second data string. The first dynamic verification value is used to authenticate a portable consumer device in a first transaction. The second data string is used to form a third data string. A second dynamic verification value is formed using at least a portion of the third data string. The second dynamic verification value is used to authenticate the portable consumer device in a second transaction.
