Patent ID: 10757137

Abstract:
Thwarting an impersonation attack using online decoy text. In one embodiment, a method may include intercepting first actual text submitted online by a first user, generating decoy text to replace the first actual text, sending the decoy text for posting online, training a machine learning model using the decoy text to make the machine learning model capable of recognizing a decoy language pattern in the decoy text, intercepting second actual text submitted to a web server by a second user purporting to be the first user, determining, using the machine learning model, that a language pattern in the second actual text matches the decoy language pattern in the decoy text, and, in response, determining that the second user is impersonating the first user in an impersonation attack and thwarting the impersonation attack by performing a remedial action at the web server to protect the web server from the impersonation attack.
