CONCLUSION

Secret writing is the art of transmitting a secret message to an individual that
cannot be read by a third person. These messages can be deciphered by a variety
of methods, such as the application of heat, the observation of the document

under UV light, and the treatment of the document with chemicals such as
phenolphthalein and iodine. In this study, the writings were deciphered by

visualising them under UV light and heat.
Hidden messages were only revealed in the chemical treatment of secret writings

when treated with iodine solution, and no changes or results were observed in
the treatment of the paper with phenolphthalein.
