Nowadays, there is a huge problem in the art field that many art works are being falsified. This problem has been solved in case of my works in two simple ways. I decided to use two techniques which have been vastly used for example in criminalistics for many years: fingerprints and DNA. Each of my works is equipped with these two signatures on the back side. Two pieces of paper. One carries my fingerprint, the other my DNA. An authentic version of each will be published on this official webpage. My fingerprint is to be found below; the DNA code will be added later. If there is a need to identify the authenticity of any of my works when bought from an insecure source, please contact some specialists in this field.
