Assignee:

Fair Isaac Corporation - Minneapolis MN

International Classification:

G06Q 40/00

US Classification:

705 44

Abstract:

A system and method for managing mass compromise of financial transaction devices is disclosed. A method includes maintaining a summary of a transaction history for a financial transaction device, and forming a device history profile based on the transaction history, the device history profile including predictive variables indicative of fraud associated with the financial transaction device. A method further includes generating a fraud score based on the predictive variables, the fraud score representing a likelihood that the financial transaction device is compromised will be used fraudulently.

Appl. No.:

11/088007

Inventors:

Liang Wang - San Gabriel CA, US

International Classification:

A46B 11/00
B43K 5/00

US Classification:

401046000, 401045000

Abstract:

A writing instrument comprises: a writing tip for spreading writing fluid on surface of written media, a first reservoir chamber having a fluid outlet for supplying the writing tip with writhing fluid, a connecting sleeve for connecting the writing tip and the first reservoir chamber, in characterized that said instrument further comprises at least one additional reservoir chamber inside or outside of the first reservoir chamber, wherein each additional reservoir chamber comprises a fluid outlet, and wherein, with relative rotation between the fluid outlet of the at least one additional reservoir chamber and the connecting sleeve, the writing fluid of the at least one additional reservoir chamber is conducted to the writing tip via the fluid outlet to supply the writing tip with the writing fluid continually. The chambers are switched by way of relative rotation to supply the writing fluid continually. The writing instrument has a reasonable structure and low cost and eliminates the leakage due to the pressure and attractive force generated by internal shock or longitudinal movement of the reservoir chambers in the prior art. The writing instrument of the present invention has the advantages of simple structure, low cast and long working life.

Abstract:

A marking instrument comprising: a marking tip for applying marking fluid on surface of written media, a first reservoir chamber having a fluid supply outlet for supplying the marking tip with marking fluid, in characterized that said instrument further comprises at least one additional reservoir chamber located inside or outside of the first reservoir chamber, the additional reservoir chamber is provided with a fluid supply outlet for supplying marking fluid to the first reservoir chamber, the first reservoir chamber comprises a fluid core having absorptive capacity, and the fluid core comprises an inlet and an outlet, wherein the inlet of the fluid core communicates with the fluid supply outlet of the additional reservoir chamber and the outlet of the fluid core communicates with the marking tip, and wherein a first exhaust outlet is formed on the first reservoir chamber and communicates with the fluid core such that the marking fluid in the additional reservoir chamber is conducted to the marking tip via the fluid core of the first reservoir chamber so as to supply marking fluid continually to the marking tip. The marking instrument of the present invention not only increases the volume for marking fluid but also effectively prevents and avoids leakage. It also extends writing time and has fluent writing and even handwriting in dark or light. The marking instrument of the present invention has a simple and reasonable structure, low cost and long working life and is convenient for wholesale manufacture.

International Classification:

G06Q 40/00

US Classification:

705 35

Abstract:

A computer-implemented fraud detection system and method are disclosed. A method includes monitoring past customer account transactions conducted with a selected one or more transaction devices, and generating a predictive model that combines customer account transaction profiles with transaction device profiles related to the one or more transaction devices, and storing a representation of the predictive model in a storage. A system for detecting fraud in financial transaction includes a fraud detection computer that receives, through a communications network, customer account transaction data obtained by a monitoring device of a transaction device according to one or more transaction device variables of a transaction device profile.
