Abstract

A means for encoding of numeric sequences, especially for encoding of PINs of bank cards, mobile telephones, etc., which contains a table consisting of columns and rows of numbers from 0 to 9. The means consists of a record register and a numeric table, where the numbers in the table are organized into basic groups containing at least one column with the number of positions at least p + 1, where p is a positive integer equal to the number of all possible numbers which can create a numeric sequence. The basic group contains at least once every randomly selected number from the sequence from 0 to 9 and at least one free position. Randomly selected numbers from the numeric sequence from 0 to 9 in the first column of the basic group are randomly distributed in all first columns of all basic groups. The second and each subsequent column of all basic groups contains at least once any of the remaining numbers from 0 to 9 and the record register contains at least z basic groups, where z is the number of digits in the code and the size of grid corresponds to that of the distribution of numbers in the numeric table.

Description

NUMBER SEQUENCE CODING AID

Technical field

The invention relates to a device for encoding a sequence of numbers, in particular for identification numbers of bank cards, mobile phones and the like, provided with a table consisting of columns and rows of numbers from zero to nine,

BACKGROUND OF THE INVENTION

In today's modern world, the individual is increasingly forced to use and therefore remember various codes, especially in the form of numerical sequences. Examples of such codes are personal identification numbers for which the acronym PIN, derived from the English term of the same meaning, Personal Identification Number, has become known. These codes, PIN, are used, for example, for bank cards, mobile phones, telephone voicemails, for phonebanking and homebanking, for car radios, as passwords for access to a computer or computer network, etc. An individual is usually equipped with multiple PINs. it cannot influence itself. It is particularly difficult for him to remember them all.

It is common for people to write down their PINs on paper that is kept at home. It is common for them to store them on computers in password-protected files or in personal electronic diaries. However, such a method is not very convenient, since the retrieval rate of the information stored in this way is relatively low and it is necessary to exert a relatively great effort to detect it. They may also use various coding aids, such as a memory card, i.e. a memory card. Memory Card, which allows you to remember only a two-digit alphanumeric key and home position instead of the entire PIN number sequence. However, its great disadvantage is that when a number of numeric sequences is required, it is not always possible to find any numeric sequence of a given length for a given key. The individual is then forced to remember different keys for different number sequences. This removes the advantage of fewer elements to remember. Another major disadvantage is also the low number of key combinations, which is at most 96.

The purpose of the present invention is to provide an aid for a simple method of coding a sequence of numbers, or to retrieve a substantially more complex code using a simple code.

SUMMARY OF THE INVENTION

The above purpose is achieved by means of a coding sequence of numbers, in particular for identification numbers of bank cards, mobile phones and the like, provided with a table with numbers from zero to nine arranged in rows and columns, according to the invention. consists of a record register and a number table, where the table numbers are arranged into basic groups consisting of at least one column with at least p + 1 positions, where p is an integer positive equal to the number of all possible digits that can form a number sequence, it contains at least one randomly selected number from a series of numbers 0 to 9 and at least one free position, whereupon randomly selected numbers from a series of numbers 0 to 9 in the first column of the base group are randomly arranged in each first column of all base groups and in the second and each of us The ice column of all base groups is at least once contained in random order of any of the remaining numbers from 0 to 9, and the record register comprises at least one of the base groups, where z is the number of code numbers and the raster size corresponds to the area distribution of numbers on the number table. The basic group is created by transposition, ie by interchanging columns with rows. The record register is created by transposing, ie interchanging columns with rows. The number table is created on transparent material or on opaque material. The recording register is made in several embodiments on a single support. The recording register is made on a self-adhesive material.

An advantage of the present invention is that it allows to find any numeric sequence of given length for any key. This means that when using the table in question, the individual must only remember the two-digit alphanumeric key and the home position to • φ φ φ φ φ · · · · · · · · · · · · φφφ φφ φφ φφ encoding all of its Numeric Sequences it uses in its life. Another advantage is the number of key combinations for which any numerical sequence, e.g. for a four-digit PIN. E.g. In a table of twenty-six columns and twenty rows, you can find 2280 key combinations for any PIN, with even more possible combinations, but not all PINs. In practice, this number is sufficiently high to prevent the user of the device from having to worry about disclosing their PINs in the event of loss or theft of the device. The advantage is the possibility of storing the device in your wallet together with payment cards. The reloading speed of the information stored with the present device is very high.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail with reference to the accompanying drawings, in which: Figure 1 shows a possible embodiment of a numeric card and Figure 2 shows nine record registers arranged on a single carrier. Fig. 3 shows all thirteen basic groups of the number card of Fig. 1. 4 and 5 illustrate the procedure for creating the next, seventh row of a numeric card as described in the description. Giant. 6 shows one basic group in transformed form, with the exchange of columns to rows and rows to columns.

Exemplary embodiment

The present aid for encoding a sequence of numbers consists of two elements, the number table of FIG. 1, formed on the transparent material, and the record registers of FIG. 2. As will be described in more detail below, a number sequence can be encoded into the record registers.

Number table 1 is created using certain fixed rules, which are as follows:

• 9

9 9 · · ·

9 · 9,999 · ♦

9 9 9 9 9 «··· ···· ·

The basic group of numbers consists of at least one column. The minimum number of positions in a group is at least p + 1. Numbers are placed in the positions.

In the basic group, at least once, all digits must be composed of a sequence of numbers. The order of digits and empty positions in the base group does not matter, on the contrary, to increase the number of key combinations, it is desirable that the order of digits and empty positions in the base group be mixed as much as possible. At least one position will remain free initially.

Simple random numbers from zero to nine placed in the first column of the base group will appear in all the first columns of all base groups of the table numbers, in any order. In multi-column base groups, the remaining columns must display at least one of the remaining numbers from zero to nine. The sequence of digits in the first and every subsequent column of the basic groups need not be followed, on the contrary, for a higher number of key combinations it is necessary to mix them as much as possible. The sum of all numbers in each individual base group must be equal to 45. Of course, following the above rules.

These numbers are arranged in such a way that the rules are further exemplified in the example shown in Figures 1, 3, 4 and 5. The numeric table shown in Figure 1 contains a set of numbers from zero to nine arranged in 26 columns, indicated by letters A to From, and up to 20 lines, marked with one to twenty serial numbers.

The distribution of numbers in individual rows and columns is done gradually, based on the basic groups, the example of the initial arrangement is shown in Figure 3. For simplicity, the first column has always selected numbers from 1 to 5, in the second column there are numbers from 6 to 9 and 0.

The first basic group S1i, as detailed in FIG. 4, consists of a raster comprising rows one to six in columns A and B. The letter A contains numbers from one to five, arranged in sequence X4-2-3-5-1, where X stands for a free position on the first line. The second column B contains numbers from six to zero, arranged in sequence 7-X-6-0-8-9, where X denotes a free position on the second row, in the same way the other basic groups S ₂ , i to Si ₃ j are occupied. the sequence of digits and empty positions in each column are different in each group.

4 4 ♦ ·························

The seventh row of the numeric table is created by moving the grid 6x 2 fields, ie.

raster of six rows and two columns, one field down. In this new group,

Si, 2 is now missing the number seven, which will appear on the seventh row of column B.

Similarly, instead of the seventh row, it can be written to an empty position in the second row of the table in column B. Similarly, in group S2.2, after moving the grid one row down, the digit one in column C is missing. However, it is also possible to enter it in the empty position in the second row of column C instead of in the seventh row.

Other table rows are occupied by the same procedure. Simple arbitrary numbers are randomly inscribed on the empty positions of the number table.

Instead of moving one field down, you can select a different number of fields.

The division of numbers into the left and right columns of each basic group can also be odd and even, or completely random. However, there must always be a rule for division of numbers in the basic group.

Base groups can also be created by interchanging columns with rows, so the group would then have 6 columns and 2 rows. Such a transposed group of numbers is shown in Fig. 6. In general, it can be established that a transposed variant exists for each variant. Each group can have arbitrarily higher number of rows and columns, which are supplemented with empty positions.

The minimum number of base groups in a number table is given by the length of the number sequence of the code. A minimum of four basic groups must be created for a table for 4-length sequences, ie a four-digit PIN. Greater than the minimum number of base groups is desirable to increase the number of key combinations.

The record register contains at least basic groups, where z is the number of Code Numbers and the raster size corresponds to the table number distribution. The minimum size of the recording register is given by the length of the number sequence. For a four-digit PIN, the minimum size of the record register is 6 rows x 8 columns, in other words, 6 rows x 4 of the base group of numbers. For a transformed group, by analogy, the minimum size of the record register is 8 rows x 6 columns, in other words, 4 base groups x 8 columns. The record register for a 4-digit number sequence must contain 4 basic groups. An exemplary record register is shown in Fig. 6. As shown in Fig. 6, for practical purposes, it is expedient to have several registers on one card. Each register is used to record one PIN.

Preferably, the number table may be printed on a transparent material of the same size as the record register card.

The device is operated by selecting a two-digit alphanumeric key, eg K2 and the basic position, eg. field in the upper left corner of the record register. The intersection given by the coordinates K2 (K for the column and 2 for the row) is then applied to it. In the reading sequence, rows from left to right, top to bottom, the position of the coded number is recorded in the register rasters. By placing the register back in the same way on the number card, individual numbers of the searched code can be subtracted from the marked fields, in the case of a transparent table above the marked fields of the register. Enough! so remember only one code, in this case K2, to recall the "forgotten" codes.
