  • Structure for secure containment of information
    Patent number: 10661594
    Abstract: A structure for secure containment of information (SSCI) that is in the form of a laminate which includes at least two layers. The laminate is constructed to contain information such as a code, serial number, informational feature, encryption key or personal identification number (PIN). The information is located between the layer of the laminate such that the code, serial number, informational feature, encryption key, or PIN is not detectable from outside the laminate. The SSCI is configured to provide access and expose the code, serial number, informational feature, encryption key, or PIN by delaminating at least one layer, thereby indicating that tampering has occurred to the laminate. The SSCI can also function as a public key or private key for a blockchain, to provide access to a physical lock or to provide account access to claim financial value.
