==INTER-HOSPITAL ELECTRONIC MEDICAL RECORD ACCESS AUTHENTICATION PROTOCOL BASED ON BLOCKCHAINS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240028761 titled 'INTER-HOSPITAL ELECTRONIC MEDICAL RECORD ACCESS AUTHENTICATION PROTOCOL BASED ON BLOCKCHAINS

==Simplified Explanation==

The abstract of the patent application describes a method for inter-hospital identity authentication and electronic medical record transfer of patients using blockchain technology. The method ensures secure and efficient transfer authentication between hospitals and allows new hospitals to access electronic medical records with patient authorization, thereby achieving reliable access controls.

* Tripartite authentication and negotiation of session keys: The patient, medical server, and doctor in each hospital achieve efficient authentication and negotiation of session keys, which are used for communication.
* Encryption of key parameters using elliptic curve: An elliptic curve is introduced to encrypt key parameters in the authentication process, improving the security of the entire process and reducing computational pressure on wireless devices.
* Dynamic anonymity policies: The patient uses dynamic anonymity policies to protect privacy during authentication and electronic medical record access.

Potential applications of this technology:
* Inter-hospital patient record transfer: The method allows for seamless transfer of patient records between hospitals, ensuring continuity of care and reducing the need for redundant medical tests.
* Remote patient consultations: With secure authentication and access controls, doctors can remotely access patient records and provide consultations, improving access to healthcare in remote areas.
* Medical research and data analysis: The blockchain-based authentication and record transfer system can facilitate the sharing of medical data for research purposes, enabling large-scale analysis and advancements in medical knowledge.

Problems solved by this technology:
* Inefficient and insecure patient record transfer: Traditional methods of transferring patient records between hospitals can be time-consuming, error-prone, and lack proper security measures. This technology solves these issues by providing a secure and efficient transfer process.
* Lack of interoperability between healthcare systems: Different hospitals and healthcare systems often use incompatible electronic medical record systems, making it difficult to share patient information. This technology enables seamless interoperability by using blockchain-based authentication and access controls.
* Privacy concerns in electronic medical record access: Patients may have concerns about the privacy and security of their medical records. The dynamic anonymity policies used in this technology address these concerns by allowing patients to control the level of anonymity during authentication and record access.

Benefits of this technology:
* Enhanced security: The use of blockchain technology and encryption techniques improves the security of patient record transfer and access, reducing the risk of unauthorized access or data breaches.
* Efficient and seamless transfer process: The method enables quick and efficient transfer of patient records between hospitals, ensuring timely access to medical information and reducing administrative burdens.
* Improved patient privacy: The dynamic anonymity policies give patients control over their privacy during authentication and record access, addressing privacy concerns and promoting patient trust in the system.


==Original Abstract Submitted==

a method for inter-hospital identity authentication and electronic medical record transfer of patients is provided. based on a blockchain technology, a patient achieves secure and efficient inter-hospital transfer authentication, and a new hospital accesses an electronic medical record with authorization of the patient, thus achieving reliable electronic medical record access controls. in each hospital, the patient, a medical server, and a doctor achieve efficient tripartite authentication and negotiation of session keys, and communicate based on the session keys. by introducing an elliptic curve to encrypt key parameters in an authentication process, a security of the entire authentication process is improved, and a computational pressure on a wireless device is reduced. in the authentication and the electronic medical record, the patient uses dynamic anonymity policies to protect privacy.
