Method and system for verifying user identity

A system, comprising:

• a processor;
• and
• a memory having programming instructions stored thereon, which, when executed by the processor, performs operations comprising:
• receiving, from a remote client device, an authentication attempt, the authentication attempt via a website associated with the system, the authentication attempt including at least a user name and a first internet protocol (IP) address associated with a router accessed by the remote client device;
• determining that data in the authentication attempt matches a user account registered with the system;
• identifying a previous authentication attempt from the remote client device, the previous authentication attempt including the user name and a second IP address associated with a second router accessed by the remote client device;
• determining that the first IP address is different from the second IP address;
• in response to determining that the first IP address is different from the second IP address, performing a further authentication process comprising:
• identifying a third party internet service provider associated with the first IP address;
• transmitting a verification message to the third party internet service provider associated with the first IP address, wherein the verification message includes identification information associated with the user account;
• and
• receiving a confirmation message from the third party internet service provider indicative of a confirmation that the identification information associated with the user account at least partially matches identification information associated with an account with the third party internet service provider;
• and
• authenticating the remote client device.

A non-transitory computer readable medium including one or more sequences of instructions, which, when executed by one or more processors, cause the one or more processors to perform operations, comprising:

• receiving, by a computing system from a remote client device, an authentication attempt via a website associated with the computing system, data of the authentication attempt including at least a user name and a first internet protocol (IP) address associated with a router accessed by the remote client device;
• determining, by the computing system, that data in the authentication attempt matches a user account registered with the computing system;
• identifying, by the computing system, a previous authentication attempt from the remote client device, data of the previous authentication attempt including the user name and a second IP address associated with a second router accessed by the remote client device;
• determining, by the computing system, that the first IP address is different from the second IP address;
• in response to determining that the first IP address is different from the second IP address, performing, by the computing system, a further authentication process comprising:
• identifying, by the computing system, a third party internet service provider associated with the first IP address;
• transmitting, by the computing system, a verification message to the third party internet service provider associated with the first IP address, wherein the verification message includes identification information associated with the user account;
• and
• receiving, by the computing system, a confirmation message from the third party internet service provider indicative of a confirmation that the identification information associated with the user account at least partially matches identification information associated with an account with the third party internet service provider;
• and
• authenticating, by the computing system, the remote client device.
