Ideograms Cipher (Lines, Circles, Dots)

Ideograms encryption associates to each letter of the plain text, a number, which is decomposed in (any) distinct values

Example: The message be crypted is DCODEZ, initially coded by (alphabetic rank) 4, 3, 15, 4, 5, 26 and selected values are 10, 5 and 1 for decomposition.
D = 4 = 0*10 + 0*5+ 4*1
O = 15 = 1*10 + 1*5 + 0*1
Z = 26 = 2*10 + 1*5 + 1*1

Each values corresponds to a selected form (basic element such as a point, a line, a line, a circle, etc.).

Example: A line = 10, a circle = 5, a dot = 1.

Draw any ideogram with these items.

Example: Z can be drawn ||o. or |.o_

Ideaograms decryption requires decomposing each ideogram in basic forms (generally between 2 and 4 distinct, the most used are dot, circle, line)

Example: Decrypt the message :: .: ∅ .... o

Count the number of appearance of each basic form in each ideogram.
:: and .... = 4 dots
.: = 3 dots
∅ = 1 circle et 1 line
o = 1 circle

Then search for values for each basic element. The value of an ideogram is given by addition.

Example: Values are line = 10, circle = 5, dot = 1.
Then ::=4 .:=3 ∅=15 ....=4 o=5

Each value corresponds to a letter, for example, the alphabetic rank (A=1, B=2, etc.)

Example: The original plain text is DCODE.

The ciphered message is composed of symbols nearly all distinct, with common factors (geometry, color, size, etc.)

One can crack Ideograms with difficulties by testing all values. Note that the value 1 appears often.

Use of colors (or any distinctive element) rather than geometric forms.

Modification of the addition calculus (eg. a color means a multiplication by N, etc.)
