Multicomputer processing to protect data from unauthorized modification

A computer-implemented method of securing data from unauthorized access, the computer-implemented method comprising:

• accessing a first document;
• determining if the first document comprises data that is only to be provided to requestors of the first document that have received authorization from a controller, using metadata associated with the first document and/or by using natural language processing, wherein the first document further comprises a first authentication indicator;
• at least partly in response to determining that the first document comprises data that is only to be provided to requestors of the first document that have received authorization from the controller generating an optical code encoding a link to an authorization request interface and/or generating a plain text link to the authorization request interface;
• generating and storing a second document comprising a modified version of the first document wherein the data that is only to be provided to requestors of the first document that have received authorization from the controller is redacted from the first document without redacting the authentication indicator and the optical code and/or plain text link is inserted into the second document;
• receiving over a network a request for the second document, comprising the first authentication indicator and the optical code and/or plain text link to the authorization request interface from a requester system;
• providing access to the requester system to the second document, comprising the first authentication indicator and the optical code and/or plain text link to the authorization request interface;
• receiving over the network, via activation of the link encoded in the optical code or the activation of the plain text link, a request for the authorization request interface;
• providing over the network, at least partly in response to the activation of the link encoded in the optical code or the activation of the plain text link, the authorization request interface to the requester system;
• receiving over the network, from the requester system, via the authorization request interface a request for the first document comprising the data that is only to be provided to requestors of the first document that have received authorization from a controller;
• transmitting over the network, to a device associated with the controller a communication regarding the request for the first document comprising the data that is only to be provided to requestors of the first document that have received authorization from a controller;
• and
• at least partly in response to receiving an approval of the request for the first document comprising the data that is only to be provided to requestors of the first document that have received authorization from a controller, providing the requester with access to the first document.

A non-transitory computer-readable medium that stores instructions, that when executed by a computing device, cause the computing device to perform operations comprising:

• access a first document comprising an authentication indicator;
• identify personally identifying information in the first document;
• generate an optical code encoding a link to an authorization request interface and/or generating a plain text link to the authorization request interface;
• generate and store a second document comprising a modified version of the first document wherein the personally identifying information is redacted from the first document without redacting the authentication indicator, and wherein the optical code and/or plain text link is inserted into the second document;
• receive a request for the second document, comprising the first authentication indicator and the optical code and/or plain text link to the authorization request interface from a requester system;
• provide access to the requester system to the second document,
• comprising the first authentication indicator and the optical code and/or plain text link to the authorization request interface;
• receive, via activation of the link encoded in the optical code or the activation of the plain text link, a request for the authorization request interface;
• provide, at least partly in response to the activation of the link encoded in the optical code or the activation of the plain text link, the authorization request interface to the requester system;
• receive from the requester system, via the authorization request interface a request for the first document comprising the personally identifying information;
• transmit, to an electronic destination associated with an authorized entity, a communication regarding the request for the first document comprising the personally identifying information;
• and
• at least partly in response to receiving an approval of the request for the first document comprising the personally identifying information, providing the requester with access to the first document.
