Patent ID: 7576842

Claim:
An identification method using a random type recognition object, comprising: a step of generating a random type recognition object wherein the random type recognition object having identification particles irregularly distributed within a 3D shape is completed; a first recognition step wherein a positional value and a characteristic value on an orthogonal coordinate of the identification particles within the random type recognition object produced in the random type recognition object-generating step are recognized from one or a number of directions on the orthogonal coordinate to complete a first data set; a second recognition step wherein the positional value and the characteristic value on the orthogonal coordinate of the identification particles distributed within the random type recognition object in which the first data set is completed in the first recognition step are recognized from one or a number of directions on the orthogonal coordinate to complete a second data set; and a step of determining whether the random type recognition object is genuine by determining whether the first data set completed in the first recognition step and the second data set completed in the second recognition step are coincident with each other, further comprising: an eigen value-assigning step of assigning an eigen value to the first data set completed in the first recognition step and storing the assigned eigen value; and an eigen value-extracting step of searching a first data set coincident with the second data set completed in the second recognition step and extracting the eigen value assigned to the first data set whose data sets are coincident with each other, wherein the step of determining whether the random type recognition object is genuine includes the step of comparing the eigen value extracted in the eigen value-extracting step with an eigen value that is already known to determine whether the random type recognition object is genuine.
