SummaryIn this article, an advanced reversible stenographic method is proposed for image and video frames by adapting dual tree complex wavelet transform and chaotic whale optimization algorithm. Here, the cover image and secret message are taken as input. In this image, the edges are identified by Canny edge detection system and embedded by the process of dual‐tree complex wave transformation method (DT‐CWT‐CWOA‐SDH) and pixel edges are optimized using the chaos whale optimization algorithm (CWOA), it optimizes the edge pixel variations and maximizes the robustness of the image and visual quality of stego image. The objective of this process is to increase the security of secret data hiding the secret message on cover image and forming the stego image by the embedding procedure and to maximize the peak signal‐to‐noise ratio (PSNR) and reduce the execution time. The proposed method runs on the MATLAB work site and the performance of proposed method is evaluated using different existing methods. The simulation outcomes illustrate that the proposed DT‐CWT‐CWOA‐SDH shows higher PSNR of 32.01%, 24.79%; lower mean square error (MSE) of 21.13%, 45.185%, normalized correlation (NC) of 11.24%, 19.04% compared with existing method.

Recently, there has been a rapid growth in the utilization of medical images in telemedicine applications. The authors in this paper presented a detailed discussion of different types of medical images and the attacks that may affect medical image transmission. This survey paper summarizes existing medical data security approaches and the different challenges associated with them. An in-depth overview of security techniques, such as cryptography, steganography, and watermarking are introduced with a full survey of recent research. The objective of the paper is to summarize and assess the different algorithms of each approach based on different parameters such as PSNR, MSE, BER, and NC.

“…Proses dalam steganografi ada 2 yaitu penyisipan (embedding) dan ekstraksi (extracting) atau memisahkan pesan informasi dari media sisipan. Proses penyisipan dilakukan oleh pengirim pesan dan proses ekstraksi dilakukan oleh penerima pesan [11]. Proses penyisipan atau embedding process merupakan proses yang dilakukan untuk menyisipkan pesan ke dalam gambar.…”

Kesadaran pentingnya keamanan data pada era digital saat ini ditandai dengan berkembangnya aplikasi keamanan data. Pada penelitian ini akan dilakukan analisis histogram terhadap suatu aplikasi keamanan data. Tujuan dari analisa ini adalah mengetahui perubahan histogram yang dilakukan penyisipan pesan. Hasilnya penyisipan pesan pada citra menggunakan Least Significant Bit secara visual tidak terlihat perubahan. Analisis histogram menunjukkan perubahan grafik terlihat lebih signifikan pada file gambar .tif, .png dan .jpg sementara .bmp tidak signifikan. Jumlah karakter yang disisipkan mempengaruhi grafik histogram. Stego image yang dihasilkan memenuhi syarat imperceptibility. Dibuktikan dari nilai PSNR yang dihasilkan yaitu PSNR >40db. Perubahan ekstensi image menjadi salah satu faktor hasil nilai PSNR. Dibuktikan dengan ekstensi image .bmp memiliki nilai MSE paling rendah dan PSNR paling tinggi yaitu, MSE=0,66141 dan PSNR=49,9601. Kata kunci: Histogram, Steganografi, LSB, Grayscale, PSNR Abstract Awareness of the importance of data security in the current digital era is marked by the development of data security applications. In this study a histogram analysis of a data security application will be performed. The purpose of this analysis is to determine the histogram changes made by message insertion. The result is the insertion of messages in the image using Least Significant Bit visually does not change. Histogram analysis shows that graph changes are more significant in .tif, .png and .jpg image files while .bmp is not significant. The number of characters inserted affects the histogram graph. The resulting stego image meets the requirements of imperceptibility. Proven from the PSNR value generated is PSNR>40dB. The change in image extension is one of the factors resulting from the PSNR value. Evidenced by the extension .bmp image has the lowest MSE value and the highest PSNR, namely, MSE=0.66141 andPSNR=49.9601. Keywords: Histogram, Steganography, LSB, Grayscale, PSNR.
