Fraud Detection

Abstract

In some embodiments, techniques for information security include receiving information related to an authentication credential, wherein the information is related to a failed authentication attempt; determining whether the authentication credential is related to a valid account; and performing a security measure related to the valid account, if it is determined that the authentication credential is related to the valid account.In some embodiments, techniques for information security include Determining that an authentication attempt has failed, applying a privacy-performing transformation such as a cryptographic hash or encryption to an authentication credential, and distributing the privacy-preserved credential.In some embodiments, techniques for information security include receiving and redistributing a privacy-preserved authentication credential.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This Application is a Continuation of U.S. patent application No. 11 / 394,764, filed Mar. 31, 2006 which claims priority to U.S. Provisional Patent Application No. 60 / 667,333, filed Mar. 31, 2005; all of the aforementioned priority applications being hereby incorporated in their entirety for all purposes.FIELD OF THE INVENTION[0002]The present invention relates generally to the area of information security. More specifically, techniques for detecting fraud are disclosed.BACKGROUND OF THE INVENTION[0003]An increasing volume of confidential information, such as personal and financial information, is being stored electronically, in locations accessible through electronic networks such as the internet. This information has value to parties who can illicitly gain access to such information.

Benefits of technology

"The invention is about detecting and preventing fraud in information security. It aims to provide techniques for identifying and reacting to potential fraud attempts, such as identity theft, in real-time. The invention involves a system for detecting and reacting to fraud, which includes a client, a network, and a server. The system can also distribute failed authentication information and process data in a privacy-preserving manner. The technical effects of the invention include improved detection and prevention of fraud, improved security of confidential information, and improved protection of privacy."

Problems solved by technology

The use of a credential incorrectly at one institution may signal potential fraud at a second institution at which the credential is valid.

Current information security technologies do not provide proactive detection of such potential fraud.
