Keamanan Data Pasien dengan Algoritma Blowfish pada HOTSPODT

Abstract


 
 
 
 At HOTSPODT (Hospital Ship for Covid Disaster) there are no stages regarding the application of the use of information technology systems, especially for securing patient data which includes personal data and patient medical records. Confidential patient data collected during the current pandemic, including the patient’s name, address, diagnosis, family history and medical records without the patient’s consent, may pose a risk to the individual concerned. The concept of patient data security is adjusted to the user’s position on the importance of data. Access to patient data authorization is one of the security gaps that the security system needs to pay attention to and guard against. So, in this case applied a data security algorithm in the form of cryptography. The algorithm used is the Blowfish Algorithm. The test results of the scenario in the application prove that it can be successfully processed from the encrypted file to ciphertext until it is returned as the original file.
 
 
 

Analisis Kriptografi Algoritma Blowfish pada Keamanan Data menggunakan Dart

“…Algoritma blowfish menerapkan simetrics key, chipher block, fistel network dan s-box pada pemrosesan enkripsi dan dekripsi [8]. Lalu kemudian pada domain dan area ilmu kriptografi, algoritma ini banyak dipergunakan karena algoritma blowfish kuat, cepat, serta tidak terbentur terhadap lisensi [9]. Untuk itu, dalam dunia kriptografi algoritma blowfish menjadi salah satu pilihan yang banyak dipakai oleh pengembang perangkat lunak yang berkutat dan menginginkan algoritma kriptografi yang bersifat terbuka, kuat, dan cepat [10].…”

Application of blockchain technology in decentralized medical data security and privacy systems

“…A method for safeguarding medical data in image format through the use of the Vigenere Cipher cryptographic algorithm was developed the earlier study [1] The Blowfish algorithm was also utilized in the previous study [2] as an encoding strategy to protect patient data confidentially; however because the algorithm is symmetric and only employs one key for file encryption and decryption, the level of security will be poor [3].…”
