Problems solved by technology

However, this does not provide a solution to how debit / credit cards are implemented and also somewhat negates the point of having a system that does not require an additional digital PIN

Embodiment Construction

[0017] refer to figure 1 , the NFC reader 106 is connected to a suitable antenna 104 . The connection may be through a suitable matching network. The NFC reader 106 sends a signal through the antenna 104 and is received by the NFC device 102 when the signal is within range. The range at which communication between the NFC reader 106 and the NFC device 102 can be ensured depends on a number of factors, including the diagonal size of the antenna used. Typically the antenna may be 4cm by 3cm, with a diagonal size of 5cm and a read range of 10cm. Other antenna sizes and shapes can be used and the read range can be greater than 10 cm or less than 10 cm.

[0018] Embodiments of the present invention provide an enhanced form of security over NFC systems by using changes in signal strength as a personalization form of security, particularly authentication.

[0019] When a user brings the NFC device 102 closer to the NFC reader, the user changes the signal strength by moving the NF...

Abstract

A system and method are disclosed for use in a near field communication system for authenticating a user of a near field communication transmitter (102) at a near field communication receiver (106), comprising: a data receiver (202), for receiving (404) a signal comprising a first unique identifier from a near field communication transmitter; a received signal strength indicator (204) for measuring (406) a signal strength of said received signal; a signal strength tracker ( 206 ) for tracking ( 406 ) a change in signal strength of said received signal over time and converting ( 408 ) said change over time into a second unique identifier; and a comparator ( 208 ) for The received first unique identifier is compared (410) to the tracked and transformed second unique identifier and a signal indicative of a result of the comparison is output.

Description

technical field [0001] The present invention relates to security in near field communication devices, and in particular to authentication for near field communication (NFC). Background technique [0002] Near Field Communication (NFC) is currently being adopted by both banks and retailers as a payment technology, allowing quick payment for products and services of small associated value. This form of payment technology provides a fast mechanism for paying using a contactless method both through traditional debit / credit cards as well as through mobile devices such as telephones. [0003] NFC is a set of short-range wireless technologies, typically operating over a distance of 10cm or less between two NFC-communicating devices. NFC operates at 13.56 MHz and transmits data at data rates ranging from 106 kbit / s to 424 kbit / s. When two NFC-compatible devices are placed at a distance of about 4 cm from each other, such as by shaking or touching, an NFC connection is established ...
