Systems, methods, and computer program products providing an identity-storing browser

A method, comprising:

• storing, by a browser server, secure user data of a user, wherein the stored secure user data is encrypted;
• receiving, by the browser server, purchase information during an electronic transaction between a browser client application of a user device of the user and an electronic shopping cart application of a merchant server;
• performing, by the browser server, a secure handshake with the electronic shopping cart application of the merchant server over a network during the electronic transaction, wherein the secure handshake is an agreed-upon protocol-based handshake operation;
• determining, based on the secure handshake, that the browser server is linked with the electronic shopping cart application through one or more shared application programming interfaces as a part of the agreed-upon protocol-based handshake operation, wherein the agreed-upon protocol-based handshake operation enables the electronic transaction to be continued without the browser server transmitting, to the electronic shopping cart application, user information of the user that is otherwise required by the electronic shopping cart application for conducting the electronic transaction with the user;
• receiving, by the browser server, user-authenticating data of the user from the browser client application;
• authenticating, by the browser server, the user, wherein authenticating the user further comprises:
• retrieving the encrypted secure user data of the user;
• decrypting the encrypted secure user data using the user-authenticating data;
• based on authenticating the user, transmitting, by the browser server, an indication of payment associated with the electronic transaction to the electronic shopping cart application;
• and
• recording the electronic transaction in a blockchain.

A non-transitory machine-readable medium having stored thereon machine-readable instructions that, when executed by one or more hardware processors of a browser server, cause the one or more hardware processors to perform operations comprising:

• storing secure user data of a user, wherein the stored secure user data is encrypted;
• receiving purchase information during a transaction between a browser client application of a user device of the user and an electronic shopping cart application of a merchant server;
• performing a secure handshake with the electronic shopping cart application of the merchant server over a network during the transaction, wherein the secure handshake is an agreed-upon protocol-based handshake operation;
• determining, based on the secure handshake, that the browser server is linked with the electronic shopping cart application through one or more shared application programming interfaces as part of the agreed-upon protocol-based handshake operation, wherein the agreed-upon protocol-based handshake operation enables the transaction to be continued without the browser server transmitting, to the electronic shopping cart application, user information of the user that is otherwise required by the electronic shopping cart application for conducting the transaction with the user;
• receiving user-authenticating data of the user from the browser client application;
• authenticating the user, wherein authenticating the user further comprises:
• retrieving the encrypted secure user data of the user;
• decrypting the encrypted secure user data using the user-authenticating data;
• based on authenticating the user, transmitting an indication of payment associated with the transaction to the electronic shopping cart application;
• and
• recording the transaction in a blockchain.
