Secure and anonymized digital transactions

A computer system comprising:

• a web application server configured to execute one or more web applications on an electronic user device;
• a shipping entity server associated with a shipping entity computing device configured to access a user's unencrypted data;
• and
• a server in communication with the electronic user device, shipping entity, and
• a merchant webserver, the server configured to:
• monitor, via a browser extension executing on the electronic user device, a web application displayed on the electronic user device;
• responsive to the web application executing on the user electronic device displaying an input element requesting personally identifiable information representing a shipping destination, input encoded user data corresponding to the input element, whereby the web application server hosting the web application does not receive the personally identifiable information representing the shipping destination;
• responsive to receiving a request for the personally identifiable information from the shipping entity server that received the encoded user data from the web application server, generating, by the server, an optical code representing the personally identifiable information;
• responsive to receiving a request for the personally identifiable information from a shipping entity computing device that scanned the optical code from a shipping label, verify the shipping entity computing device;
• and
• upon verifying the shipping entity computing device and verifying that a passcode input by a user of the shipping entity computing device matches a label-specific passcode that is generated specifically for use with the shipping label and is known by the server, present decoded user data comprising the personally identifiable information for display in the form of a decoded augmented reality label comprising the decoded user data in lieu of the encoded user data on the shipping entity computing device.
