In this paper, a new genetic coding technique is proposed. The proposed method is unpredictable and more reliable than other methods. In the proposed method, any digital data is converted to binary form and then goes through the steps of DNA sequencing, transformation, encoding, reproduction, mutation and finally transformation. The main steps of the proposed method are repeated several times (three or more times) and the encrypted data is transmitted as text or image files. On the other hand, in the proposed model, the receiver is used to decrypt and transform the transmitted data into the original data. This technique often converts text to image and image to text. This increases the security and accuracy of data transmission. By employing multiple key sequences to increase propagation rate and uncertainty, the decryption process becomes significantly more difficult and intricate. This approach facilitates the development of a comprehensive encryption system. Experimental results show that the proposed method includes multi-layered defense steps based on multi-stage and genetic operations. This technique provides higher security against various attacks. The decrypted information is more suitable for use due to its fundamental differences from confidential information.
