- Literature review
- Problem definition; How to make stegano-image more resilient while transmitted on telegram.
- Since telegram uses JPEG compression, implementing a JPEG steganography method that can provide robustness is in order
- JPEG uses DCT to compress data so a steganography method based on DCT was implemented
- In this implementation, we tried to combine the idea of the previous studies to improve security and stability
- To maintain error correction, hamming encoding was implemented
- The result shows that even if the image is subjected to some sort of distortion and degradation, we would be able to recover the message
