## Cryptographic Solution for Secure Healthcare Application
* Overview of secure data transmission and storage for healthcare systems.
* Prepared as part of a TCS iON project at Amity University Online.

## Project Objectives
* Implementation of encryption, hashing, and digital signatures.
* Focus on maintaining confidentiality, integrity, and trust in patient records.

## Healthcare Data Protection
* Protects PII (Personally Identifiable Information), medical history, and diagnostic reports.
* Ensures authorized access for doctors and staff over secure network channels.

## Core Security Techniques
* **Symmetric Encryption (AES):** Used for bulk data encryption to protect records at rest.
* **Asymmetric Encryption (RSA):** Facilitates secure key exchanges between clients and servers.
* **Hash Functions (SHA-256):** Used for securing passwords and verifying that records are unaltered.
* **Digital Signatures:** Provides non-repudiation for medical reports and confirms physician identity.

## Secure Architecture & TLS
* **HTTPS/TLS:** Establishes encrypted links between web servers and browsers to prevent Man-in-the-Middle attacks.
* **End-to-End Security:** Integration of encryption in transit and at rest for comprehensive data defense.

## Outcomes
* Significant reduction in the risk of data breaches.
* Verification of doctor approval via digital signatures.
* Guaranteed data integrity through cryptographic hashing.
