LT6885B - Encryption device - Google Patents

Abstract

The invention relates to an encryption device which allows a user to encrypt several four-digit numbers associated with several devices in use, so that they can only be decoded by a user who knows one decoding code. The encoder consists of a solid base to which four wheels are rotatably attached, each wheel having five code openings, each for recording one digit of a particular code, and one cipher opening for matching a user-generated device code. The digits of the cipher are written in a circle on the base under the wheels, starting with 0 and ending with 9, so as to coincide with the cipher opening. Each code opening on each wheel is marked with a differently coloured circumferential ring. The code openings on all four wheels, marked in a matching colour, represent the corresponding four-digit code. Because each wheel has five code openings, a total of five different four-digit codes can be encoded. The device may be used as a stand-alone device or may be incorporated as an integral part of magazines, calendars and other similar publications.

Description

FIELD OF THE INVENTION

The invention relates to an encoding device that allows a user to encrypt multiple four-digit numbers associated with multiple devices in use so that only a user who knows a single decoding cipher can decrypt them. The device may be used as a stand-alone device or may be incorporated as an integral part of magazines, calendars, and other similar publications.

State of the art

In these modern times, many of us use a variety of devices, items, or devices whose activation or unlocking involves entering a corresponding code that only the user of that device knows. It can be a smartphone PIN, it can be a suitcase lock code, it can be, for example, a bike lock code, it can be a code for a corresponding application or a digital password, it can be a bank card PIN and so on. In order not to forget those codes, we have to either memorize them, which is not easy when there are so many of them, or write them down somewhere. In the latter case, however, there is a risk that openly written code could fall into the wrong hands.

U.S. Pat. US3864857 describes a device for recording and recalling a telephone number when needed. It is a small, simple and inexpensive mechanical device in which several wheels with numbers inscribed on the surface of their outer edge are mounted on a single shaft, the wheels protruding through a box cut in the device, representing a certain sequence of numbers. The user simply has to turn the sequentially arranged digital dials so that they represent the desired phone number to be reminded in the future.

The disadvantage of the device is that it can only store one digital code.

Another encoder is described in U.S. Pat. US1271000. It is a mechanical multi-turn disk encoder that allows you to encrypt and then decrypt entire messages. The device consists of several rotating discs with an alphabet mounted in a housing.

However, the construction of the device is technically complex and, being made of metal, is quite heavy and inconvenient to use.

Brief Description of the Invention

The object of the present invention is to provide a simple coding device which can be made of plastic or cardboard, allowing coding of up to five four-digit codes. The device may be used as a stand-alone device or may be incorporated as an integral part of magazines, calendars, and similar publications.

The encoder consists of a solid base to which four wheels are rotatably mounted, each wheel having five cut-out boxes, each for storing one digit of a particular code, and one cut-out box for matching a user-generated device code. The digits of the cipher are written in a circle on the base under the wheels, starting at 0 and ending with 9, so as to coincide with the cipher box.

Each code box on each wheel is marked with a different colored perimeter ring. The code boxes for all four wheels, marked in a matching color, represent the corresponding four-digit code. Because each wheel has five code boxes, a total of five different four-digit codes can be encoded.

Description of the drawing

The invention will now be described with reference to the accompanying drawings, in which:

fig. is a general view of the encoding device of the present invention;

fig. a view of one of the code boxes of the encoder is provided;

fig. the base view of the encoder is shown.

Detailed Description of the Invention

As shown in Figs. or a combination thereof.

The wheels 3 are cut out of five code boxes 4 arranged evenly in a circle. Each code box 4 on each wheel 3 is marked with a ring 5 of a different color. This means that each wheel 3 has five code boxes 4 with rings of a different color 5. The same colors 5 of the boxes 4 are used on all wheels 3.

Each wheel 3 of the encoder has an additional cipher box 6, the position of which, when the wheel 3 is rotated about the axis 2, coincides with the numbers 0 ... 9 written in a circle on the base 1 of the encoder.

At the bottom of the coding device, five oblong boxes are defined, colored in five different colors, coinciding with the 5 colors of the 4 rings of the coding boxes.

Using the Code Device

To enter the code of some device or the codes of all five devices, we turn each wheel 3 of the encoder so that the boxes 6 of all four wheels 3 in turn coincide with the four-digit code we came up with, which will then be used to decode the same five-digit codes. Then, in the four code boxes 4 of all four wheels 3 with rings of the same color 5, we enter the four-digit code required to save or remember. Matching colored boxes 4 indicate a single code. Because we have boxes 4 in five different colors, we can enter a total of five four-digit codes in them. The figures are written on the base of the coding unit 1.

We now turn the wheels 3 of the encoder so that the cipher boxes 6 coincide with the other numbers 0 to 9 of the base 1, and we write any imaginary numbers in the boxes 4 of the wheels 3. And this is done until we fill in all the empty positions in box 4 of the wheels 3, corresponding to the positions 0 to 9 in box 6 of each wheel 3.

In the boxes 7 of the base 1, the colors of which correspond to the colors 5 of the boxes 4 of the wheels 3, it is possible to write in any color and at the same time the four-digit code corresponding to that color. For example, telephone, suitcase, home alarm and so on.

To see the four-digit codes, we turn the wheels 3 of the encoder so that the boxes 6 of all four wheels 3 coincide with our original invented cipher. Then in the wheel boxes 4, marked with rings of the same color 5, we will see all five real decoded codes.
