プロジェクトの始めに現れる無秩序に並んだ色彩のモザイクは、one-time padと言われる暗号技術で、ある画像の色彩情報に乱数でビット単位の XOR 演算をして暗号化した画像です。ひとつひとつの正方形にはRed, Green, Blueの情報が含まれています。もうひとつ同じ量の情報の乱数データがありますが、このビデオ画面には画像として見せていません。その乱数は画像を解読する工程で、ビデオ画面に表されたバイナリの値で見ることはできます。暗号化された画像に対して、この乱数は鍵と考えることができます。
モザイク画像は、1970年代初頭のゲルハルト・リヒターの「シリーズ・オブ・カラー・チャート」等の絵画と同じように正方形の色彩の配置い見えるかもしれません。しかしこのプロジェクトのモザイクは、物理的に混合した色彩をキャンバス上に並べた画像ではなく、光学的に色を混ぜることで見る人の目を惹きつけようと、フランスのポスト印象派の画家ジョルジュ・スーラにインスピレーションを得ています。スーラのアイデアのように色彩要素を混合してして、元の画像を再現します。これはone-time padと言われる暗号技術を使って、すべての画像データに乱数をビット単位の XOR 演算をして、色彩情報を暗号化します。別な言葉では、暗号を解く鍵(乱数)とその暗号(無秩序に並んだ正方形の色彩画像)に分離するとも言えるでしょう。

The project includes several themes such as "Chaos and Order," "Perception and Cognition," and "New Value Created by Technology.

Chaos and Order:
The artist Kenji Kojima believes that the world around him is full of chaotic information. Sense organs construct the world by extracting only certain components from the chaos, such as visual and auditory information, like a filter. It is that you construct your world with the "key" of a sense organ as if you were deciphering a code.
The chaotically arranged color mosaic that appears at the beginning of the video is an encrypted image created by bitwise XOR operations of random numbers on the color information of a given image using a cryptographic technique. Each square contains Red, Green, and Blue information. There is another random number of data with the same amount of information, but it is not displayed as an image on this video screen. The random numbers can be seen as binary values displayed on the video screen during the image decoding process. This random number can be thought of as a key for encrypted images.
The mosaic image may resemble the arrangement of color squares, similar to paintings such as Gerhard Richter's "Color Chart Series" from the early 1970s. However, the mosaics in this project are inspired by optical color mixing, rather than the physical arrangement of mixed colors on canvas. The project is to recreate the original image by mixing color elements as Seurat did. This uses a cryptographic technique called a one-time pad to encrypt color information by performing a bitwise XOR operation on all image data with random numbers. In other words, it can be said to be separated into the code-breaking key (random numbers) and the code (colored images of randomly arranged squares).

Perception and Recognition:
The chaotic mosaic of colors is decoded using random numbers that match the key and becomes a cave painting in Lascaux, France. The artist Kojima believes that the visual information obtained from chaos is also mixed with auditory information. The project's next stage was to obtain the color information from the Lascaux cave paintings in binary form and attempt to convert it into a musical scale. He set the center of the RGB value to be the middle C of the piano keyboard, automatically assigning it to the 12-tone scale. In the video, RGB values are randomly sampled from five locations, and musical notes are made from those values and played on the piano, ocarina, and bell. Currently, all media, including visual and auditory ones, are converted into binary and recorded as data. The artist is considering the possibility of converting binary data into other formats, such as visual to auditory, as artwork.

New Value Created by Technology:
Artist Kojima believes that "NFT art" is not art, but a financial product. The greatest feature of digital art is that it allows for unlimited reproduction of real artwork. If a genuine artwork were to be copied infinitely, its monetary value would disappear. He is trying to eliminate the abnormal financial situation of art that is embedded in capitalism and give it a different meaning. If art had meaning even after its monetary value disappeared, it would revive the connection with the viewer here.

Hide: Kenji Kojima's Biography
Kenji Kojima is a digital artist. Since the early 1990s, he has been experimenting with the relationships between perception and cognition, technology, music, and visual art. He was born in Japan and moved to New York in 1980. He spent his first 10 years in New York City painting with egg tempera. The personal computer improved rapidly in the 1980s. He felt more comfortable with computer art than painting. He converted his artwork to digital in the early 1990s. He developed the computer software for his artwork. But there was a big problem, the software soon did not work on the operating system. He converted his artwork to video while it was working. His ecology-based software and video art were exhibited in New York and at media art festivals around the world. After Covid-19, he could not go out to make a video. In 2021 he started a new series called "The Musical Interpretation of Paintings". At the end of 2023, he returned to his art theme of ecology. LiveCode programmer. Kenji Kojima Resume
