Definitions
- This invention relates to the encryption of information for example
- a propulsion means for propelling the writing plane a propulsion means for propelling the writing plane
- key pad with pre-set memory for controlling the speed, direction and/or frequency
- FIG. 1 is an isometric view of a
- Fig 1 a is a side cross
- Fig 2 is an oscillating marking device, in this case, a ball point pen.
- the outer case 5 houses the writing plane 1, the key
- the propulsion means is oscillating solenoids with a movement of, in this example about 2 mm, the movement will vary if the frequency is altered as is known and documented.
- the solenoids' coils are secured to the outer casing and the reciprocating components are attached to the writing plane 1 which is suspended on linear bearings (not shown).
- the object to be signed 3 is held in place by the clips 2.
- the frequency memory circuit 7 sends a pre-set frequency to the oscillating solenoids 8 (as is known and documented), whereby causing the writing plane to oscillate .
- the pen case 9 has a ball point pen 10 inserted into the solenoids 11, controlled by the frequency memory circuits 12 powered by the battery 13 and manually adjustable by the adjustment knob 14.
- the ball point pen 10 is oscillating along its axis by means of the oscillating solenoids 11.
- a low friction bearing 15 surrounds the ball point pen to glide over the writing surface when the ball is not in contact.
- the arrangement being such that when the frequency of the writing
- acceleration, deceleration and speed of a signature will provide a unique map.
- the writing plane could be in the form of a wipe clean surface or till roll type arrangement with a carbonated ribbon running over the writing plane for the encrypted image and under the till roll for an encrypted mirror image. This will allow image processing equipment to read the image from inside the encryption device, which will be described in more detail below.
- Fig 1 and Fig 2 can be wired together to harmonise the two frequencies or can be used independently.
- the variations of the embodiment are many and varied in the spirit of the idea, for example the document can be moved in any direction, the effect of which will compress, elongate, loop, pillar up or pillar down the written text and the drive means can be a DC or AC motor, stepper motor and can be directly driven by a crank or cam, and indirectly by belts or levers.
- the process can be used for product identification, used in conjunction with CNC machines, or to produce a bar code type language customised to the users' security requirements.
- the device can be integrated into any relevant unit such as a scanner, till printer, or counter top.
