The invention relates to methods and apparatus for matching a query data object with a candidate data object by esetracting and comparing fingerprints of said data objects. In an embodiment of the invention apparatus comprising a fingerprint extraction module (110), a fingerprint matching module (210), a statistical module (120) and an identification module is provided. The fingerprint extraction module (110) receives an information signal forming part of a query object and constructs a query fingerprint. The fingerprint matching module (210) compares the query fingerprint to candidates stored in a database (215) to find at least on potentially best matching candidate. Meanwhile, the statistical module determines a statistical model of the query fingerprint so as to, for instance, determine the statistical distribution of certain information inside the query fingerprint. The threshold determiner (120) is arranged, on the basis of the distribution of the query fingerprint to derive an adaptive threshold distance within which the query fingerprint and a potentially best matching candidate may be declared similar by the identification module (130). By setting a threshold which may depend on statistical data derived from the query and / or candidate fingerprint, an improved false acceptance rate F.A.R. may be achieved.

A method and system of increasing the acceptance rate in fingerprint scans by the application of cascaded selective, plural and sequenced fingerprint recognition rules using a plurality of sensors. The finger is swiped over multiple sensors. A whole fingerprint sample is constructed from the scan of each of the multiple sensors, thereby generating a multiplicity of whole fingerprint samples. Predetermined selective, plural and sequenced fingerprint recognition rules are set for each of the whole fingerprint samples. The sequence of application of the rules is set for the fingerprint recognition. The accuracy level for fingerprint recognition is set. The selective, plural and sequenced fingerprint recognition rules are sequentially applied to match the captured fingerprint image with stored fingerprint templates. The stored fingerprint templates are sequentially filtered until the set accuracy level is achieved.

Utilization of information in a closed loop data system further augments modeling while at the same time enabling customization of offers based on spend patterns. Data mining techniques are leveraged to identify rules to determine higher response rate populations. These rules are referred to herein as “triggers,” in that the presence of particular attributes will trigger a cardholder as being more likely to respond to a particular offer. The benefit yielded by this approach is a greater acceptance rate to an offer provided by a transactional account company. To identify the triggers, records of cardmembers who already utilize a given product are analyzed to determine their spend patterns. The spend histories of customers who are eligible to use the product are analyzed according to the identified triggers. Customers whose spend patterns most closely correspond to the triggers are then targeted with offers for the given product.

An apparatus for link layer port-based hardware implemented acceptance rate limiting control is presented. The apparatus employs a single up-down counter tracking a receive port buffer occupancy level. The single up-down counter is incremented by a receive line rate clock signal time truncated by a frame receive signal and a feedback frame acceptance control signal. The single up-down counter is decremented at an Service Level Agreement (SLA) agreed upon committed rate at which content is extracted from the receive port buffer. Outputs of comparators determining when the port receive buffer occupancy level is below a low watermark receive port buffer occupancy level, and when the receive port buffer occupancy level is above a maximum burst size, are provided to a master slave flip flop generating the frame acceptance control signal exhibiting hysteresis as the port receive buffer occupancy level transitions between the low watermark and the maximum burst size receive port buffer occupancy levels. The advantages of the link layer port-based hardware implemented acceptance rate limiting control achieved are derived from a deterministic response enforced in real time, at line rate, as content is being received employing a small number of logic gates.

The invention discloses a vehicle network-accessing method based on IEEE 802.11p. The method can adapt to the requirements of vehicular ad-hoc network safety applications for time delay and acceptance rates. The VeDA which is based on 802.11p / DSRC allows vehicles to access to a shared channel in a contention-free period. The VeDA scheme supports two safety services (emergency safety messages and route safety messages) with different priorities and provides a strict time delay limit. The VeDA makes a DTIM frame divided into a contention-free period and a contention period. Two types of safety messages are accessed to the channel through VeDA Opportunities in a predetermined way. VDAOPs are multiple time slots of the contention-free period. The non-safety messages are accessed to the channel in the contention period in a contention means. As proved by simulation effects, the VeDA can effectively guarantee the time delay and the acceptance rate of safety messages. Especially in high communication load conditions, the VeDA is better than an accessing scheme based on a back-off algorithm in terms of time delay and acceptance rates.
