SYSTEMS AND METHODS FOR PROTECTION AGAINST THEFT OF USER CREDENTIALS

Abstract:

A computer system is provided. The computer system includes a memory and at least one processor coupled to the memory and configured to receive a sequence of characters within a field of a web browser, the field being associated with a password entry field served to the web browser from a website. The processor is further configured to store the received sequence of characters and send an alternate sequence of characters to the website. The processor is further configured to encrypt the received sequence of characters to generate a received encrypted partial password and compare the received encrypted partial password to one or more entries in a list of encrypted partial passwords. The processor is further configured to, in response to the comparison resulting in a difference, delete the previously sent alternate sequence of characters, and send the stored sequence of characters to the website.
