Abstract
Transformasi digital kesehatan memerlukan infrastruktur terdesentralisasi untuk mengatasi kerentanan keamanan pada sistem terpusat. Penelitian ini merancang platform teleradiologi berbasis web-aplikasi dengan arsitektur keamanan berlapis yang mengintegrasikan steganografi hibrida Discrete Wavelet Transform-Singular Value Decomposition (DWT-SVD) dan pra-pengacakan Arnold Cat Map, penyimpanan InterPlanetary File System (IPFS) berbasis Secure Hash Algorithm (SHA-256), smart contract blockchain Proof-of-Authority (PoA), Zero-Knowledge Proof (ZKP), serta enkripsi Elliptic Curve Integrated Encryption Scheme (ECIES). Pengujian pada 200 citra medis menunjukkan tingkat imperceptibility yang tinggi, ditandai dengan Peak Signal-to-Noise Ratio (PSNR) 43,29±0,16 dB, Structural Similarity Index Measure (SSIM) 0,9894±0,0032, Normalized Correlation (NC) 0,9983±0,0009, dan Bit Error Rate (BER) 0,0179±0,0043. Sistem terbukti tahan terhadap kompresi JPEG, namun kinerjanya menurun pada serangan noise dan filter. Waktu proses embedding dan extraction masing-masing memerlukan 35,00 ms dan 20,48 ms, dengan verifikasi ZKP Groth16 sebesar 343,25 ms. Integrasi IPFS dan PoA secara inheren meniadakan risiko single point of failure. Latensi end-to-end sistem mencapai 19 detik, memenuhi standar layanan gawat darurat (STAT). Penelitian ini menyajikan proof-of-concept yang memberikan fondasi arsitektural solid bagi ekosistem teleradiologi aman di Indonesia.

Digital transformation in healthcare requires a decentralized infrastructure to address security vulnerabilities in centralized systems. This study designs a web-based teleradiology platform with a layered security architecture that integrates hybrid steganography using Discrete Wavelet Transform -Singular Value Decomposition (DWT-SVD) and Arnold Cat Map pre-randomization, Secure Hash Algorithm (SHA-256)-based InterPlanetary File System (IPFS) storage, Proof-of-Authority (PoA) blockchain smart contracts, Zero-Knowledge Proof (ZKP), and Elliptic Curve Integrated Encryption Scheme (ECIES). Testing on 200 medical images demonstrated a high level of imperceptibility, characterized by a Peak Signal-to-Noise Ratio (PSNR) of 43.29±0.16 dB, a Structural Similarity Index Measure (SSIM) of 0.9894 ± 0.0032, a Normalized Correlation (NC) of 0.9983 ± 0.0009, and a Bit Error Rate (BER) of 0.0179 ± 0.0043. The system proved resistant to JPEG compression, but its performance degraded under noise and filter attacks. The embedding and extraction processes took 35.00 ms and 20.48 ms, respectively, with Groth16 ZKP verification taking 343.25 ms. The integration of IPFS and PoA inherently eliminates the risk of a single point of failure. The system’s end-to-end latency is 19 seconds, meeting the STAT (emergency) service standard. This research presents a proof-of-concept that provides a solid architectural foundation for a secure teleradiology ecosystem in Indonesia.
