Accelerated communication attack detection

A system for authenticating a user of a client device at a server, the method comprising:

• a memory configured to store information regarding the hardware, software, or network information related to the client device or biometric information related to the user;
• a processor configured to execute computer instructions for:
• prompting the user to enter only a subset of characters at a specific position in a username associated with the user;
• prompting the user to enter only a subset of characters at a specific position in a password or a one-time-use password;
• collecting information regarding the hardware, software, or network information related to the client device or biometric information related to the user;
• encrypting data, using a computer microprocessor associated with the client device, with the subset of characters in the username or password, one-time-use password, or collected information;
• transmitting the encrypted data from the client device to the server via a network link therebetween;
• decrypting the data, at the server, using a server-side copy of the username, password, and collected information;
• and
• when no matching server-side copy of the username, password, and collected information exists, prompting the client for a series of challenge questions or a new client registration process to establish a record on the server of client parameters.
