Secured cloud computing for medical data based on watermarking and encryption

Abstract

In this study, the authors propose a hardware implementation of a local cloud for storing, sharing and archiving patient's folders (health report and medical imaging) based on raspberry Pi card and a local cloud (hard disc) while exchanging with other distant public cloud (google drive, azure cloud, …). Securing the medical data is ensured by a proposed encrypting method for the watermarked digital imaging and communications in medicine imaging which contains the patient information (the watermark) and the advanced encryption standard is used to crypt the text files (health reports). The imaging encryption method is based on the exoring of the ith block to be encrypted and the ith block key. The watermarking method is based on the insertion of the watermark in the least significant bit. Finally, encryption and watermarking keys are encrypted and stored in the database. A real-time implementation on raspberry Pi and android smartphone is proposed for the whole system using, respectively, PHP and android studio. Experimental results demonstrate that the proposed security method is robust against different types of attacks and can achieve high security with a good performance.

Ensuring Information Security in Electronic Health Record System Using Cryptography and Cuckoo Search Algorithm

“…Collectively, these innovative approaches have facilitated efficient and secure sharing of medical data while preserving user privacy and data confidentiality. By employing a combination of techniques such as biometrics-based authentication, secure data aggregation, encryption and compression of medical data, watermarking, quantum information hiding, and cancelable biometric templates, researchers have effectively addressed the security and privacy challenges associated with EHRS [18].…”

Medical Image Transmission Using Novel Crypto-Compression Scheme

“…In [20], a model is presented that can protect digital multimedia content on unprotected open networks, offering security for patient information. Digital cryptography should be adapted for medical images before diffusion followed by achieving; this technique is suggested as an effective model to provide information security to patients.…”

Robust and Secure Watermarking for Propagation of Digital Multimedia by Paillier Homomorphic Cryptosystem With Arnold Transformation

“…Their scheme requires both the cover and signed images to get extracted watermarks. Boussif et al (2018) had discussed a proposed secure medical cloud for archiving and transmission of medical data (images and reports). They use AES encryption to encrypt the text file and LSB method for hiding the patient information in the medical image.…”
