Security key system

摘要

An aspect of the disclosure includes a security system and method having a key with nanoscale features. The key includes a body. At least one pattern member disposed on the body, the pattern member formed using a directed self-assembly polymer to define a pattern of random feature structures thereon, the feature structures having a width of less than 100 nanometers.

主权项

1. A key of claim for a security system comprising:
a body, the body includes a first side and a second side; at least one pattern member disposed on the body, the at least one pattern member formed using a directed self-assembly polymer formed from a first polymer and a second polymer, the first polymer and second polymer each having a different length and arranged in an alternating arrangement, the first polymer and second polymer configured to define a pattern of random feature structures thereon, the feature structures having a width of less than 100 nanometers; wherein the at least one pattern member includes a plurality of pattern members, each of the pattern members being formed using the directed self-assembly polymer to define the pattern of random feature structures thereon, each of the random feature structures being different from other random feature structures; wherein a first plurality of pattern members of the plurality of pattern members is arranged on the first side and a second plurality of pattern members of the plurality of pattern members is arranged on the second side; wherein the body includes a third side and a fourth side; and wherein the plurality of pattern members further includes a third plurality of pattern members arranged on the third side and a fourth plurality of pattern member arranged on the fourth side.
