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： 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.
摘要翻译：提供了用于验证持卡人身份的方法，系统和装置。卡的磁条的磁特性的数字表示被存储在持卡人的便携式电子设备上。在交易期间，然后传输数字签名，使其能够与参考签名进行比较。可以验证身份，并且例如在请求方和被验证方之间的交易期间发送到请求验证的一方的响应。
