Embodiment Construction

[0020] In the following description, it should be understood that all recited connections between structures may be direct operative connections, or indirect operative connections through intermediate structures. A set of features contains one or more features. Any reference to an element should be understood as referring to at least one element. Multiple features contains at least two features. Unless otherwise required, any described method steps do not necessarily have to be performed in the particular illustrated order. A first element (eg, data) derived from a second element encompasses the first element equal to the second element, as well as the first element produced by processing the second element and optionally other data. Making a determination or decision based on parameters encompasses making a determination or decision based on parameters and optionally other data. Unless otherwise specified, an indicator of a quantity / data may be the quantity / data itself, or...

Abstract

In some embodiments, an online fraud prevention system combines the output of several distinct fraud filters, to produce an aggregate score indicative of the likelihood that a surveyed target document (e.g. webpage, email) is fraudulent. Newly implemented fraud filters can be incorporated and ageing fraud filters can be phased out without the need to recalculate individual scores or to renormalize the aggregate fraud score. Every time the output of an individual filter is calculated, the aggregate score is updated in a manner which ensures the aggregate score remains within predetermined bounds defined by a minimum allowable score and a maximum allowable score (e.g., 0 to 100).

Description

Background technique [0001] The present invention relates to methods and systems for detecting online fraud. [0002] Online fraud, especially in the form of phishing and identity theft, continues to pose a growing threat to Internet users worldwide. Sensitive identity information such as usernames, IDs, passwords, social security numbers and medical records, bank and credit card details fraudulently obtained through international criminal networks operating on the Internet are used to withdraw private funds and / or are resold to third parties . In addition to the immediate financial loss to the individual, online scams lead to many unwanted side effects such as increased security costs for the company, higher retail prices and bank charges, lower stock values, lower wages and reduced tax revenue. [0003] In an exemplary phishing attempt, a fake website (sometimes called a clone website) can masquerade as a real webpage belonging to an online retailer or financial institutio...
