Data protector, data protection seal, and drawing device

A drawing device that performs at least one of writing or erasing on a data layer and one or a plurality of cover layers of a data protector, the data protector including the data layer on which confidential information is to be recorded as a visible image and the one or the plurality of cover layers, the data layer including a first reversible material configured to transition between a color-developed state and a decolored state in a visible light wavelength region, the one or the plurality of cover layers including a second reversible material configured to transition between the color-developed state and the decolored state in the light visible wavelength region and being disposed at least one of above or below the data layer, the drawing device comprising:

• a light source section that emits laser light beams, the laser light beams being at least one of a first laser light beam or a second laser light beam, the first laser light beam having a condition in which a reaction of color development and decoloring of the first reversible material does not occur and in which a reaction of any one of color development and decoloring of the second reversible material occurs, the second laser light beam having a condition in which a reaction of color development and decoloring of the second reversible material does not occur and in which a reaction of any one of color development and decoloring of the first reversible material occurs;
• and
• an optical section that performs at least one of writing or erasing on the data layer or the one or the plurality of cover layers by applying the laser light beams emitted from the light source section on the data layer or the one or the plurality of cover layers.

A data protector comprising:

• a data layer configured to record confidential information as a visible image;
• one or a plurality of cover layers disposed at least one of above or below the data layer and configured to transition between a color-developed state and a decolored state in a visible light wavelength region, wherein the one or a plurality of cover layers includes a leuco dye;
• a heat-insulating layer between the one or the plurality of cover layers and the data layer;
• and
• one or a plurality of water vapor barrier layers that protects the one or the plurality of cover layers and has a water vapor permeability of 0.1 g/m2/day or less.

A data protector comprising:

• a data layer configured to record confidential information as a visible image;
• one or a plurality of cover layers disposed at least one of above or below the data layer and configured to transition between a color-developed state and a decolored state in a visible light wavelength region, wherein the one or a plurality of cover layers includes a leuco dye;
• a heat-insulating layer between the one or the plurality of cover layers and the data layer;
• and one or a plurality of ultraviolet protection layers that protects the one or the plurality of cover layers and has an optical transmittance of 70% or less for light having a wavelength shorter than 420 nm.
