System and method for password protection

A computer-based system for password protection, the system comprising a plurality of software modules stored in a memory and executable by a processor, the modules comprising:

• a password interception module configured to intercept a plurality of data entry events generated by a data entry device, wherein the plurality of data entry events comprise a user-entered password;
• an anomaly detection module configured to detect an anomaly event in the plurality of intercepted data entry events;
• a database storing one or more preset anomalies and replacement character strings;
• a password conversion module configured to:
• compare the detected anomaly event with the one or more preset anomalies stored in the database;
• if the detected anomaly event matches at least one preset anomaly, identify a replacement character string associated with said at least one preset anomaly, wherein the associated replacement character string is different from the detected anomaly;
• replace the detected anomaly event in the plurality of intercepted data entry events with the replacement character string to generate a converted password;
• and
• send the converted password instead of the user-entered password to a user authentication device for authentication of the user based at least on the converted password.

A computer program product embedded in a non-transitory computer-readable storage medium, the computer-readable storage medium comprising computer-executable instructions for password protection, the medium comprising instructions for:

• intercepting a plurality of data entry events generated by a data entry device, wherein the plurality of data entry events comprise a user-entered password;
• detecting an anomaly event in the plurality of intercepted data entry events;
• comparing the detected anomaly event with one or more preset anomalies;
• if the detected anomaly event matches at least one preset anomaly, identifying a replacement character string associated with said at least one preset anomaly, wherein the associated replacement character string is different from the detected anomaly;
• replacing the detected anomaly event in the plurality of intercepted data entry events with the replacement character string to generate a converted password;
• and
• sending the converted password instead of the user-entered password to a user authentication device for authentication of the user based at least on the converted password.
