ENCODING INFORMATION IN PHYSICAL PROPERTIES OF AN OBJECT

摘要

A method, system for encoding or decoding information in physical properties of an object. A tangible product comprises a three dimensional tangible object having modified physical properties; and wherein the modified physical properties are a modification of physical properties, wherein the modification encodes information. A method comprising: obtaining a representation of a three dimensional object having physical properties; obtaining information to encode; determining modified physical properties by modifying the physical properties to encode within the modified physical properties the information; and producing a tangible product, wherein the tangible product is the three dimensional object having the modified physical properties.

1. A method comprising:
obtaining a representation of a three dimensional object having physical properties; obtaining information to encode within the three dimensional object when produced; modifying the physical properties to determine modified physical properties, wherein said modifying comprises encoding the information within the physical properties; and producing a tangible product, wherein the tangible product is the three dimensional object having the modified physical properties, whereby the tangible product encodes within its physical properties the information, whereby the information is decodable from the tangible product.
