“…Transposition model is basically making ciphertext by changing plaintext object-object position without shifting the plaintext object, thus in this technique another character is not needed [33]. Reading the matrix value column by column based on the key used is done to get the ciphertext by using this transposition technique [34]. Chiper example of character transposition technique from "Universitas Mulawarman Samarinda" plaintext and using of frame 9x4 is shown by Figure 5.…”

Development of prototype at data security through secret messages is needed for disguising the messages sent in smartphone chatting application, WhatsApp (WA) Chat. We propose a model to disguise a plaintext message which is first encrypted by cryptosystem to change the plaintext message to ciphertext. Plaintext or plainimage entering the smartphone system is changed into encrypted text; receiver then can read the message by using similar key with the sender. The weakness of this proposal is the message random system is not planted directly in the chatting application; therefore message removing process from cryptosystem to WA application is still needed. The strength of using this model is the messages sent will not be easily re-encrypted by hacker and can be used at client computing section.

“…Sukhla dkk [3] dalam penelitiannya menyebutkan bahwa algoritma kunci simetris, yaitu Vernam Cipher dapat digunakan untuk meningkatkan keamanan data baik dalam proses enkripsi maupun dekripsi. Mamta Jain [4] dalam penelitiannya menyebutkan bahwa algoritma Vernam Cipher juga telah diterapkan dalam teknik steganografi untuk mengamankan data. Sari, dkk [5] dalam penelitiannya menyebutkan bahwa algoritma Vernam Cipher dapat digunakan untuk proses enkripsi beberapa jenis file dengan ekstensi yang berbeda-beda dan telah digabungkan dengan teknik steganografi End of File.…”

Penggunaan media online dalam melakukan aktivitas telah semakin marak terjadi pada dinamika masyarakat modern. Salah satu obyek sasaran dalam aktivitas online adalah citra digital. Citra digital ini dapat diperuntukan untuk kalangan terbatas saja sehingga mudah menjadi sasaran oleh peretas, terutama jika data citra digital tersebut bersifat penting. Disinilah kriptografi mengambil peran penting dalam mengamankan citra digital. Dengan menggunakan teknik Vernam Cipher, pesan citra digital dapat diacak dengan kunci yang berbeda untuk setiap karakter, sehingga pesan citra digital hanya dapat dibaca oleh penerima saja. Hasil enkripsi akan menghasilkan citra baru dengan adanya perubahan pada intensitas warna piksel. Dari 12 gambar dengan ukuran kurang dari 100 KB, tingkat keberhasilannya adalah 100%. Algoritma ini sangat cepat, dengan kecepatan enkripsi rata-rata 0,007785 dan dekripsi 0,006903 untuk gambar berformat JPEG dan memiliki ukuran piksel 384x384 Berdasarkan penelitian tersebut maka dapat disimpulkan bahwa Algoritma Vernam Cipher adalah algoritma yang baik dan cepat.

“…Several types of research [12]- [14] showed that the amalgamation of this transformation in a steganography scheme could be more improved. Others including [15]- [17], associate steganographic and cryptography techniques to improve the security of private messages. There are different cryptographic techniques, including one time pad (OTP), advanced encryption standard (AES), rivest-shamir-adleman (RSA), data encryption standard (DES), and blowfish [16], [18], [19].…”

In this modern era, it has become much simpler to replicate, sell, and copy the copyright owners' works without their permission as a result of the expansion of digitalization, and it is difficult to identify such violations, posing a threat to the creators' and copyright owners' rights. For many years, the internet has been regarded as one of the most serious threats to copyright, and the content available has varying levels of copyright protection. On the internet, there are numerous copyrighted works, including e-books, movies, news, and so on. Therefore, by using watermarking and steganography techniques, these issues can be solved, which are based on the author's signature information or logo. This paper concluded that the techniques of discrete cosine transform (DCT), discrete wavelet transform (DWT), one-time pad (OTP), and playfair are highly effective when used together to watermark an image or embed a secret message, our lab results validate that our algorithm scheme is robust against several sets of attacks, where the algorithm was assessed by computation of many evaluation metrics such as mean square error (MSE), signal-to-noise ratio (SNR), and peak signal-to-noise ratio (PSNR).
