Abstract:Image enhancement merupakan prosedur yang digunakan untuk memproses gambar sehingga dapat memperbaiki atau meningkatkan kualitas gambar agar selanjutnya dapat dianalis untuk tujuan tertentu. Ada banyak algoritma image enhancement yang dapat diterapkan pada suatu gambar, salah satunya dapat menggunakan algoritma structural similarity index measure (SSIM), algoritma ini berfungsi sebagai alat ukur dalam menilai kualitas gambar, bekerja dengan membandingkan fitur structural dari gambar, dan kualitas gambar dijela… Show more
“…So, can find out and get how the level of accuracy and success of the encryption and decryption process that has been studied. Structural Similarity Index Metrics or SSIM is one of the methods used to determine and measure the level of similarity between 2 images [10]. The structural Similarity Index Metrics algorithm is done by comparing structural features.…”

“…With the value of d is 1<d<⌽(n), so e.d = 1(mod ⌽(n). According to the Chinese Remainder Theorem (CRT) equation which states that a.b(mod d) is equivalent to a=b+k.m, or it can be expressed by the equation: (10) By experimenting the value of d = 0, 1, 2, 3, … so that it fulfills the equation.…”
Technological developments, especially smartphones, have led to an authentication process that must be developed. One of them is the use of the iris in the authentication process. The use of the iris can increase security in the authentication process because the structure of the iris is unique and differs from individual to individual. Authentication requires encryption and decryption processes to secure data. This research uses Rubik's Cube algorithm and the Rivest-Shamir-Adleman (RSA) algorithm. This study aimed to obtain the accuracy and time efficiency results used in the encryption and decryption process. In this study, the encryption process was carried out using Rubik's Cube algorithm, followed by encryption using the RSA algorithm. In the decryption process, it was obtained using the RSA algorithm, then continued with the decryption using the Rubik's Cube algorithm. The experimental results indicate that the encrypted image results differ from the initial image. With the results, the average Structural Similarity Index Metrics (SSIM) is 0,01, and the average Mean Square Error (MSE) is 37620,59. Furthermore, evaluations of the encryption and decryption process time were also carried out using the RSA public key (197,403) and RSA private key (53,403). The maximum iteration of Rubik's Cube algorithm was 1. In the encryption process, the average time was 0,796 s, and the decryption process obtained an average time of 0,652 s. This study has brought new procedures for securing digital images that can be developed in further studies.
