Abstract

A data protector according to one embodiment of the present disclosure comprises a data layer configured so that confidential information can be recorded as a visible image, and one or a plurality of cover layers that are arranged above and / or below the data layer and that are configured so as to be capable of transitioning between a color-developing state and a decoloring state in a visible wavelength region.

Description

technical field [0001] The present disclosure relates to a data protector, a data protection seal, and a drawing device. Background technique [0002] In the case where important information such as passwords and encryption keys are stored for a long time and stored on a recording medium connected to a computer, there is a possibility that the stored information is stolen by a third party or becomes Unreadable question. Currently, printing it on paper and storing it is considered the safest method. However, the risk of information leakage due to illegal viewing by a third party or the risk of print loss due to paper or ink deterioration is not zero. For example, the disclosure described in the following PTL1 is known as a measure for suppressing illegal viewing by a third party. [0003] citation list [0004] patent documents [0005] PTL1: Japanese Unexamined Patent Application Publication No. 2007-65266 Contents of the invention [0006] However, in the disclosure...
