Abstract
Abstract Control over the authenticity of serially numbered objects is provided by applying an ordered pair of numbers (including alphanumeric characters as well as any other type of indicia, visible or not visible, used for identification purposes and readable by humans and/or machines) to each object, one of the pair being serially selected and constituting an identification number, and the other of the pair being ramdomly selected and constituting a control number. A master list is kept of the ordered pairs of numbers as they are applied to objects so that the authenticity of an object can be ascertained at a later date by comparing the control number of an object with the control number in the master list associated with the identification number of the object.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
61 words
Apparatus for providing control over the authenticity of a set of objects comprising a. a settable identification number printer; b. a settable control number printer; c. a random number generator associated with and establishing the setting of the control number printer; and d. control means for causing the printers to print an identification number and a control number on an object.
Claim 2
Dependent Claim
61 words
Apparatus for providing control over the authenticity of a set of objects comprising a. a settable identification number printer; b. a settable control number printer; c. a random number generator associated with and establishing the setting of the control number printer; and d. control means for causing the printers to print an identification number and a control number on an object.
Claim 3
Dependent Claim
32 words
Apparatus in accordance with claim 1 wherein the identification number printer is set by incrementing it after each printing to establish a sequential relationship between the identification numbers of sequentially printed objects.
Claim 4
Dependent Claim
36 words
Apparatus according to claim 2 wherein the random number generator establishes a random relationship between the control numbers of sequentially printed objects and between the control number of one object and the identification number associated therewith.
Claim 5
Dependent Claim
68 words
Apparatus in accordance with claim 3 wherein each digit position of the control number printer has a rotatable disc containing indicia on the edge thereof selectively engageable with an object to be printed, and a driver associated with each disc and responsive to the output of the random number generator for establishing the angular position of the disc and hence the indicia to be printed on an object.
Claim 6
Dependent Claim
22 words
Apparatus in accordance with claim 4 including an identification number generator associated with and establishing the setting of the identification number printer.
Claim 7
Dependent Claim
52 words
Apparatus in accordance with claim 5 including comparator means for comparing the identification number and control number actually printed on an object as an ordered pair of numbers with the contents of the identification number and control number generators, and for responding to such a comparison by indicating when a discrepancy exists.
Claim 8
Dependent Claim
39 words
Apparatus according to claim 6 including an auxiliary printer for printing out those ordered pairs of numbers indicated by the comparator means whereby a list is obtained of those objects whose ordered pair of numbers has been improperly selected.
Claim 9
Dependent Claim
84 words
Apparatus for applying an ordered pair of numbers to each object of a set comprising: a. an identification number printer, and a control number printer; b. a control number printer having at least one rotatable disc; c. means for regularly incrementing the identification number printer in response to printing an identification number on an object; and d. means for rotating the disc independently of the incrementing of the identification number printer including the disc in response to printing a control number on an object.
Claim 10
Dependent Claim
84 words
Apparatus for applying an ordered pair of numbers to each object of a set comprising: a. an identification number printer, and a control number printer; b. a control number printer having at least one rotatable disc; c. means for regularly incrementing the identification number printer in response to printing an identification number on an object; and d. means for rotating the disc independently of the incrementing of the identification number printer including the disc in response to printing a control number on an object.
