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.

1 . A method for electronic security, comprising:
 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.
