Systems and methods for generating secure tags

A method for generating a two-part label, comprising:

• generating a first secure tag that encodes first tag data as a selection of potential first secure tag feature options using the first tag data, a first numeric seed, and a first stylesheet;
• generating a second secure tag that encodes second tag data as a selection of potential second secure tag feature options using the second tag data, a second numeric seed, and a second stylesheet;
• determining a difference image between the first secure tag and the second secure tag;
• labelling a substrate with the first secure tag;
• and
• detachably adhering an overlay to the substrate, the overly labelled with the difference image and aligned with the first secure tag.

A method for providing documents, comprising:

• generating a first secure tag paired to a document, the first secure tag encoding an identifier of the document using a selection of potential tag feature options;
• receiving, from a first device, an access request for the document;
• providing, to the first device, the first secure tag;
• receiving, from a second device, a confirmation request including a secure tag image;
• comparing the first secure tag to the secure tag image;
• and
• providing the document to the first device based on the comparison.
