Abstract
A method for authenticating an object, comprising determining a physical dispersion pattern of a set of elements, determining a physical characteristic of the set of elements which is distinct from a physical characteristic producible by a transfer printing technology, determining a digital code associated with the object defining the physical dispersion pattern, and authenticating the object by verifying a correspondence of the digital code with the physical dispersion pattern, and verifying the physical characteristic.
Claims20
A handheld optical code reader, comprising:
- a wireless digital data communication network interface configured to communicate over a digital data communication network;
- a camera configured to acquire a set of pixels representing optical characteristics of at least one feature of a physical object;
- at least one automated digital processor, configured to:
- recognize symbols in the set of pixels;
- convert the set of pixels from the camera to a surface projection of an image;
- determine characteristics of an expected image of a portion of the physical object distinct from the symbols, dependent on the recognized symbols;
- perform a stochastic analysis of at least a portion of the image with respect to deviations of the image from the characteristics of the expected image;
- and
- authenticate the physical object based on at least the stochastic analysis and an acceptable error metric;
- and
- an output display configured to present an authentication status.
A non-transitory computer readable medium storing instructions for controlling at least one automated digital processor of an optical code reader, comprising:
- instructions for capturing an image of a physical object from a digital camera;
- instructions for recognizing symbols in the image;
- instructions for determining characteristics of an expected image of a portion of the physical object distinct from the symbols, dependent on the recognized symbols;
- instructions for performing a stochastic analysis of at least a portion of the image with respect to deviations of the image from the characteristics of the expected image;
- and
- instructions for authenticating the physical object based on at least the stochastic analysis and an acceptable error metric.
A method of authenticating a physical object with an optical code reader, comprising:
- communicating over a digital data communication network through wireless digital data communication network interface;
- acquiring a set of pixels representing optical characteristics of at least one feature of a physical object with a camera;
- automatically recognizing symbols in the set of pixels;
- automatically converting the set of pixels from the camera to a surface projection of an image;
- automatically determining characteristics of an expected image of a portion of the physical object distinct from the symbols, dependent on the recognized symbols;
- automatically performing a stochastic analysis of at least a portion of the image with respect to deviations of the image from the characteristics of the expected image;
- and
- automatically authenticating the physical object based on at least the stochastic analysis and an acceptable error metric.
