For their own vested interests, hackers are frequently willing to hack secret documents. Establishing a secure relationship between the secret message and image quality is the most difficult task. To prevent illegal attacks by an unknown person, the suggested approach combines cryptography and visual steganography techniques. Image and message security will be enabled by this approach. Cryptographic algorithms based on the International Data Encryption Algorithm (IDEA) and steganography algorithms based on the Discrete Cosine Transform (DCT). Cryptography's goal is to encrypt and decrypt the document. Steganography is a technique for securely transmitting secret data over the internet that involves hiding documents within an image with increasing payload. We show a single application in this paper to mask the sender's information, which is an important document and a secret file. Unauthorized users will be unable to see the form. With a payload of 52,400 bytes of information in an image, the PSNR is 90.06 dB.
