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.

A method for imposing electronic security at a first secure site, the method comprising:

using one or more processors to perform steps comprising:
receiving information related to (i) an authentication credential, and (ii) a failed authentication attempt that occurs at a second secure site that is independent of the first site;
making a determination that the authentication credential, received as information related to the failed authentication attempt that occurred at the second site, is related to a valid account maintained at the first secure site;
and
performing, at the first secure site, a security measure related to the valid account in response to the determination that the authentication credential is related to the valid account;
wherein receiving information related to the authentication credential includes receiving the information in a privacy-preserving form, including in the form of a cryptographic hash.
