Secure transmission of digital content over a computer network

A system provided by a first entity, the system comprising:

• one or more processors;
• one or more storage media storing instructions which, when executed by the one or more processors, cause:
• sending, to a computing device of a second entity that is different than the first entity, a plurality of predefined attributes;
• receiving, from the computing device of the second entity, input that selects a subset of the plurality of predefined attributes;
• receiving, from a computing device of a third entity that is different than the first entity and the second entity, a request;
• in response to receiving the request:
• identifying an identity of the third entity;
• identifying the subset;
• retrieving, from a profile of the third entity, based on the subset, a plurality of values, wherein each value in the plurality of values corresponds to a different attribute in the subset;
• storing the plurality of values in association with the third entity;
• prior to sending the plurality of values to the second entity, sending, over a network, to a computer system of the second entity, a notification that an entity has submitted information that is ready for the second entity to retrieve.

A method performed by a first entity, the method comprising:

• sending, to a computing device of a second entity that is different than the first entity, a plurality of predefined attributes;
• receiving, from the computing device of the second entity, input that selects a subset of the plurality of predefined attributes;
• receiving, from a computing device of a third entity that is different than the first entity and the second entity, a request;
• in response to receiving the request:
• identifying the subset;
• identifying a plurality of values based on a profile of the third entity, wherein each value in the plurality of values corresponds to a different attribute in the subset;
• determining that a first attribute in the subset is associated with an editable indicator;
• determining that a second attribute in the subset is associated with a non-editable indicator;
• and
• sending, to the computing device of the third entity, the plurality of values, wherein sending the plurality of values comprises:
• causing a first value, in the plurality of values and corresponding to the first attribute, to be presented on the computing device of the third entity in a first text field that is editable, and
• causing a second value, in the plurality of values and corresponding to the second attribute, to be presented on the computing device of the third entity in a second text field that is not editable;
• wherein the method is performed by one or more computing devices.
