Abstract:
A tamper indicating optical security device that operates to produce one or more synthetic images is provided. Any attempt to detach (e.g., forcibly remove) this device from an underlying base material will cause one or more layers of the security device to separate or delaminate, rending the device partially or totally inoperable. The inventive device is contemplated for use with, among other things, currency or banknotes, secure documents such as bonds, checks, travelers checks, identification cards, lottery tickets, passports, postage stamps, and stock certificates, as well as non-secure documents such as stationery items and labels. The inventive device is also contemplated for use with consumer goods as well as bags or packaging used with consumer goods.
