5. A positive identification device for verifying the authenticity of the user of a document coded with visible identification information, where the authorized user of said document has been given a secret code for memorization which corresponds to said visible identification information, said device comprising: a. first entering means comprising at least one user dial for manually entering a user code into said device, said user dial having along its outer edge indicia corresponding to said user code; b. second entering means for manually entering said visible identification information into said device; c. an indicator; d. a power source; e. an electrical circuit having an enabled and disabled state, said electrical circuit comprising a plurality of first switches which are responsive in a predetermined manner to said manually entered user code and which have an on state and an off state, and a plurality of second switches equal in number to said first switches, said second switches each having an on state and an off state, said second switches being responsive in a predetermined manner to said manually entered visible identification information, said second entering means composing a plurality of manually operated single throw switching members equal in number to said second switches, said single throw switching members having markings corresponding to said visible identification information, each of said single throw switching members being wired to a respective one of said second switches so that each of said second switches is actuated upon its respective single throw switching member being thrown into the on position, said first switches and said second switches being respectively wired together so that the state of said electrical circuit becomes enabled only upon the changing of state of said first switches being complementary to the changing of state of said second switches, said electrical circuit being connected with said indicator and said power source, said indicator being responsive to said electrical circuit being enabled, said indicator being activated only if said manually entered user code corresponds to said manually entered visible identification information; f. actuating means for actuating said first switches, said actuating means being controlled in a predetermined manner by said first entering means, said actuating means having a plurality of coupling members equal in number to said first switches, each of said coupling members being coupled to a respective said first switch, said actuating means further having an axle and at lease one cylinder having a circular cavity at each of its ends each of said cylinder's ends having a rim of narrow width, said cylinder being rotatably mounted upon said axle, said cylinder having upon its surface a plurality of engaging means for cooperatively engaging with said coupling members, said engaging means arranged in a predetermined manner, said cylinder being located in a close proximity to said coupling members so that said engaging means can engage said coupling members, each of said first switches being actuated upon its respective said coupling member being engaged by said engaging means, said user dial being rotatably mounted on said axle, said user dial being secured to said cylinder, said indicia along the outer edge of said user dial being aligned with said engaging means in a predetermined manner; g. a stressed torque spring, said stressed torque spring surrounding said axle, said stressed torque spring being connected to and positioned between said user dial and said cylinder when said user dial and said cylinder are secured to each other, said stressed torque spring being compressed and twisted so that it propels said user dial and said cylinder apart and causes them to rotate in opposite directions upon their ceasing to be secured together, thereby preventing the detection of the predetermined manner in which said indicia along the outer edge of said user dial and said engaging means were aligned with each other; and h. at least one I-beam, the number of said I-beams greater than one being equal to the number of said cylinders greater than two, said I-beam surrounding said axle, said I-beam being positioned adjacent said end of said cylinder opposite said user dial, said I-beam having spacers of narrow width disposed along its sides and coincident with said rim of said cylinder opposite to said user dial, said spacers being disposed so that said cylinder and said user dial are compressed together so that they are secured to each other, but would no longer be secured to each other if said first I-beam is displaced a small distance.
11. The device of claim 5 wherein one of said rims of each of said at least one cylinder has a tooth and notch pattern on it and the side of each of said at least one user dial has a complementary tooth and notch pattern on it so that said user dial and said cylinder mesh with each other and rotate in fixed relation to each other when secured together.
