Email address token integration

An e-commerce computer system that utilizes Simple Mail Transfer Protocol (SMTP) to improve security of an e-commerce transaction, the e-commerce computer system comprising:

• a memory;
• a communication interface that is communicatively coupled to a client device via a network;
• and
• a processor communicatively coupled to the communication interface and the memory;
• wherein the processor is configured to:
• receive, using the communication interface, a request for a transaction from a third party, wherein the transaction enables a particular registered user to access a secure webpage hosted by the third party,
• in response to receiving the request:
• generate a short lookup token for the transaction, wherein the short lookup token identifies the particular registered user and is unique to the transaction;
• and
• configure, a transaction email address to contain the short lookup token in a local part of the transaction email address, wherein the e-commerce computer system receives email via the transaction email address;
• receive, using the communication interface, a response email from a sender via SMTP, wherein the response email is addressed to the transaction email address,
• ascertain the particular registered user based on the short lookup token contained in the local part of the transaction email address,
• authenticate the response email by determining that the response email was received from the particular registered user based on an email address of the sender of the response email, and
• on a condition that the response email is successfully authenticated:
• determine a long token associated with the short lookup token based on information stored in the memory, wherein the long token includes additional information about the transaction not included in the short lookup token;
• process the transaction utilizing the additional information included in the long token;
• and
• log the particular registered user on to the secure webpage based on the transaction being processed, wherein the particular registered user is logged onto to the secure webpage by transmitting a notification to a browser of the particular registered use.

A non-transitory computer readable storage medium that stores instructions for utilizing Simple Mail Transfer Protocol (SMTP) to improve security of an e-commerce computer system, the instructions when executed by a processor of the e-commerce computer system cause the processor to execute a method, the method comprising:

• receiving a request for a transaction from a third party, wherein the transaction enables a particular registered user to access a secure webpage hosted by the third party;
• in response to receiving the request:
• generating a short lookup token for the transaction, wherein the short lookup token identifies the particular registered user and is unique to the transaction, and
• configuring a transaction email address to contain the short lookup token in a local part of the transaction email address, wherein the e-commerce computer system receives email via the transaction email address;
• receiving a response email from a sender via SMTP, wherein the response email is addressed to the transaction email address;
• ascertaining the particular registered user based on the short lookup token contained in the local part of the transaction email address;
• authenticating the response email by determining that the response email was received from the particular registered user based on an email address of the sender of the response email;
• and
• on a condition that the response email is successfully authenticated:
• determining a long token associated with the short lookup token, wherein the long token includes additional information about the transaction not included in the short lookup token,
• processing the transaction utilizing the additional information included in the long token, and
• logging the particular registered user on to the secure webpage based on the processing, wherein the particular registered user is logged onto to the secure webpage by transmitting a notification to a browser of the particular registered user.
