Abstract

Application Programming Interface (API) is an interface built by system developer so some or entire functions of the system can programatically be accessed. Representational State Transfer (REST) is one of API development architectural style that uses Hypertext Transfer Protocol (HTTP) for data communication. This research implemented REST in developing API as the back-end of the skincare clinic patient information system. API was developed using Javascript Object Notation (JSON) as the standard format for data communication and JSON Web Token (JWT) as user authentication code. This research indicates that the development of API successfully performed on the patient administration of skin care clinic and implementation of REST makes it easy to develop API structures. This research produced REST API-based back-end for the patient administration information system of skin care clinic. API was tested in three stages: JWT testing on multiple back-end servers, API testing with Equivalence Partitioning and system functional testing. Keywords: application programming interface (api), hypertext transfer protocol (http), javascript object notation (json), json web token (jwt), representational state transfer (rest).

Abstract

Teknologi membuat cara komunikasi menjadi lebih baik, tidak dibatasi oleh tempat dan waktu. Bentuk komunikasi yang sering digunakan adalah mengirim dan menerima pesan. Hal ini menuntuk sistem keamanan yang kuat. Metode kriptografi merupakan salah satu cara pengamanan pesan dengan mengubah bentuk pesan sehingga sulit dipahami. Selain itu, metode steganografi merupakan cara untuk menyembunyikan pesan ke dalam media penampung. Kriptografi dan steganografi membuat keamanan suatu pesan lebih baik. Dalam penelitian ini dilakukan perbandingan antara kriptografi RSA (Rivest Shamir Adleman) dan kriptografi transposisi kolom yang disisipkan kedalam media penampung menggunakan steganografi AMELSBR  (Adaptive Minimum Error Least Significant Bit Replacement), dengan media penampung berupa gambar dengan ekstensi .JPG sebgai input (cover image), dan menghasilkan output .JPG (stegoimage). Kesimpulan yang didapat dari penelitian ini adalah ciphertext transposisi kolom memiliki waktu lebih cepat saat proses penyisipan dan menghasilkan stegoimage yang lebih kecil dibandingkan ciphertext RSA. Tetapi ciphertext RSA lebih tahan terhadap perlakuan pemotongan gambar dibandingkan ciphertext transposisi kolom. Sebagian media sosial dapat mengirimkan stegoimage secara sempurna apabila tidak terdapat proses kompresi yang dilakukan.
