Systems and methods for real-time encryption of sensitive data

A system for protecting data input to a web-based application, the system comprising:

• one or more processors;
• and
• memory readable by the one or more processors and that stores therein a set of instructions which, when executed by the one or more processors, causes the system to:
• execute, within a web browser being executed by the system, a web-based application, wherein executing the web-based application comprises:
• tagging one or more data fields as sensitive;
• and
• fetching a public key from a remote server system;
• identify, by the web-based application being executed within the web browser, a keystroke entry being input to the one or more data fields tagged as sensitive within the web-based application;
• prior to storing the keystroke entry in memory mapped to the web browser, encrypt, by the web-based application being executed within the web browser, the keystroke entry using the fetched public key to generate an encrypted entry;
• store, by the web browser, the encrypted entry to memory, wherein the keystroke entry is never stored to memory of the web browser in an unencrypted form;
• present, by the web browser, a representation of the keystroke entry in the data field tagged as sensitive;
• and
• transmit, by the web-based application being executed within the web browser, the encrypted entry to the remote server system.

A non-transitory processor-readable medium, comprising processor-readable instructions configured to cause one or more processors to:

• execute, within a web browser, a web-based application, wherein executing the web-based application comprises:
• tagging one or more data fields as sensitive;
• and
• fetching a public key from a remote server system;
• identify, by the web-based application being executed within the web browser, a keystroke entry being input to the one or more data fields tagged as sensitive within the web-based application;
• prior to storing the keystroke entry in memory mapped to the web browser, encrypt, by the web-based application being executed within the web browser, the keystroke entry using the fetched public key to generate an encrypted entry;
• store, by the web browser, the encrypted entry to memory, wherein the keystroke entry is never stored to memory of the web browser in an unencrypted form;
• present, by the web browser, a representation of the keystroke entry in the data field tagged as sensitive;
• and
• transmit, by the web-based application being executed within the web browser, the encrypted entry to the remote server system.
