This Post is about a way to Decentralized Healthcare Information System, and a Company,
With a very interesting project about it.
Once the patient overcomes the bureaucratic barrier by requesting patient's request for personal information, a new problem arises.
Virtually every medical institution has a closed system in most cases incompatible with those of other institutions. And if we talk about our medical data being spread in several medical institutions, it becomes more difficult.
 MediBloc Youtube For example, a patient may have to retake the same blood and X-ray tests when they change from hospital A to hospital B. A patient may also have to revisit the hospital and pay for a medical report. Patients are often victims of this additional cost with the current record keeping system.
This leads to many problems, as doctors may have trouble providing adequate treatment if a patient incorrectly communicates his medical history. Medical researchers can only have limited access to medical records data due to private data protection laws.
 Source BlockChain is a tool as powerful as it is effective and it is probably the closest way, known in the last decades, that we will have to protect and decentralize the handling of clinical information.
The overall vision of BlockChain is to create a common database of medical information in which doctors and providers can access regardless of the electronic system they use, with greater security and privacy. A decentralized system would imply less administration time, so there would be more time to dedicate it to patient care and even better share the results of the research in order to contribute to knowledge.
Some probable applications of BlockChain in health can be listed in medical data management, while electronic medical records can be improved and allow safe access of patient records to any provider that needs it, solving the waste of time, money and duplication of procedures, confusion and sometimes even life problems. The records are distributed among many different facilities and providers.
MediBloc is a technology company building a decentralized personal health record (PHR) platform on blockchain. Currently, medical records are fragmented and scattered across medical institutions. MediBloc aims to integrate these records and create a patient-centric platform which will allow patients to utilize their healthcare data.
 MediBloc Whitepaper page 07 MediBloc seeks to give patients total control over their medical's history data, as well as the authority to choose who has access to their medical data. MediBloc, wishes to grant ownership of medical records to its users (patients) and not to hospitals or health entities, who even can charge for a copy of the documents. To explain this easily, when a patient needs to change hospital, but it is ubicate in another city or country, must invest time and money to "recover" their medical records, but in worse cases with the possibility of partial or total loss of the record. With MediBloc it can not happen, the patient has the full right to personally handle his medical record without relying on hospitals or doctors, the patient simply allows access to medical records to the new medical institutions he will attend, saving time and money, as long as them are part of the MediBloc platform. MediBloc seeks to mix the world of health with the world of technology in order to ensure, consolidate and provide easy access to all medical records of a person, this with the same effectiveness and security offered by the Blockchain for financial transactions ( Cryptocurrencies), for this reason it is completely safe to integrate all the scattered medical data of several institutions (even from other countries) of the patient and add it to the MediBloc platform. Another important aspect of MediBloc is that data can be collected via smartphone.or another personal device.

MediBloc Benefits
Maximum Security
Starting from the premise that all medical information must be confidential, each institution establishes the mechanics it deems necessary to protect it, but this means the participation of intermediaries in the backup of the data, who have access to it, increasing the risk of leaks, manipulation or even loss of the data. There may also be cases where data is taken without the patient's consent.
MediBloc through its platform Bockchain aims to transfer to each patient the authority to access, collect and share all of their healthcare information, without any type of intermediary. In a way similar to how it is done in the cryptocurrency exchange Blockchain platforms.
High Reliability
MediBloc Store all healthcare information in a decentralized data storage, which prevents the loss of data. The platform is designed so that it is not easy for users to delete or edit the data stored on the platform, in addition to this, data integrity checks are continuously carried out and data is frequently backed up.
It is important to note that the healthcare provider's credential guarantees that only verified medical practitioners can access the data and they can only see it after receiving authority from the owner (patient).
These 2 characteristics guarantee a High Reliability of the MediBloc platform
High level of Transparency
With MediBloc you are the owner of your data, allowing consumers the authority to handle everything concerning their healthcare data.
MediBloc in order to guarantee High level of Transparency, Record all the activity concerning who write, read and have access to medical information on the MediBloc blockchain.
However MediBloc will transparently provid This information, including tracking of who, when, where and for what purpose the healthcare information was used.
In this way, users are always aware of the use that is being made of their healthcare data. In conventional systems this is not possible and patients in most cases have no idea who checks their healthcare data and if it is being used without their consent.
A healthcare data will be encrypted and stored in a distributed database outside the blockchain. (IPFS, etc) Only the hashed value of the healthcare data is recorded onto the blockchain. Therefore, what random people see when accessing the blockchain is the hash value of the medical data, not the healthcare data itself.
High Interoperability
One of the aspects that most slows the fact that currently our medical data is currently centralized is the lack of standardized. transfer to medical history of a patient from one hospital to another is something that continues to cause headaches.
One of the main advantages offered by MediBloc is due to the fact that it is an open source platform, which allows several applications within the MediBloc ecosystem to interact and connect allowing the use of data stored on the platform between them.
The standardized data like medical images or genetic information can easily be transferred through the MediBloc Platform.
For other hand, no standardized data like medical records, laboratory results, test, etc. MediBloc establishes several formats.
The major plan for MediBloc is provide API / SDK various formats like FHIR (Fast Healthcare Interoperability Resources).
As well as taking into account the flexibility of the MediBloc platform, there is the possibility to develop a code that supports other formats to upgrade the interoperability.
Finally MediBloc intends its platform to interact with EMR / EHR systems that use different hospitals to interoperate with MediBloc platform.
MediBloc pretend partnering with existing EMR and EHR system providers to expand the interoperability.
High Accessibility
Just need internet, with access to internet, all users can easily handle all about their Healthcare data. This way you save time and money looking for your medical records in medical centers. This becomes more important when the patient is ill.
As mentioned above, you only need internet access and you can do it with your Smartphone, a few touch of the screen and you can easily access all your medical information and allow access to the medical institution. At this moment the medical institution will have access to all your medical history, the MediBloc Platform has High Accessibility.
Important to highlight the data is completely restricted outside medical institution
Currently is not possible access without a personal device. Each personal devices will store a private key to decrypt the encrypted medical data.
Because each personal device requires a private key, currently is not possible use.
Patient Centered Healthcare Information System.
A very interesting aspect within the Medibloc ecosystem. Previously it has been commented on the studies carried out by medical institutions within the platform, but in addition to this, patients can also make their contribution
With Collectively stores Patient Generated Health Record (PGHR).
This consists in the storage of the data recorder by patients, which can be contributed to medical investigations outside the MediBloc blockchain.
MediBloc Technical detail.
The MediBloc platform consists of 3 layers: Core, Service, and Application.
First Layer: MediBloc Core.
In simple words, the core layer is a healthcare data network, responsible for storing all Personal and medical information.
This data is collected and transferred by means of the MediBloc provided SDK applications and later it is encrypted using an individual private key, only the owner of the personal healthcare data can decrypt and reveals it. The encrypted data itself is stored on a decentralized, distributed storage network. But since the amount of data stored in the blockchain is limited, the Healthcare data will be stored in a distributed database outside the blockchain like InterPlanetary File System (IPFS).
The core layer is accessible through the service layer and provides a backup and recovery system as prevention.
MediBloc platform is an EVM decentralization application (DApp), EVM is supported by multiple blockchain platforms like ethereum and Qtum which makes MediBloc a flexible platform.
MediBloc uses Qtum for being the most scalable and public blockchain for using POS (Proof of Stake) consensus algorithm.
Also Qtum is a China platform and MediBloc will operate here (and Korea) and it can suppose advance into the Chinese market
Second layer MediBloc Service
In simple words, this is the blockchain layer information and provide the necessary services to link the other 2 layer, High layer - Application and Low layer - Core, as well, a easy transfer flow (input / output) of data with the core layer.
Service layer make use of EVM (Ethereum Virtual Machine) Smart contract, this include MED balance and medical information within the core layer.
MediBloc Application Layer
This is the "visible" layer where all the applications (developed for website environments, smartphones, tablets, etc.) compatible with the Medibloc ecosystem that can handle healthcare information coexist. These applications are accessible through the Service Layer.
Application Layer is where users can access their medical data, they can observe their MED balance, review their history and other functions such as information search, automatic insurance claim, medical reports, exchange of medical data with researchers and medical institutions.
This application is targeted at three types of accounts: general users, doctors and medical institutions, and data researchers.
MediBloc SDK
For easier and faster app development, MediBloc offer SDK, which will help create applications that can be linked to MediBloc platform. However, from a technical point of view, developer communities can build new services with the MediBloc platform API and SDK to exchange data with the platform and drive innovations in the healthcare applications market.
MediBloc do not restrict users to any use of SDK, as long as developers follow the communication protocols for the future platform
MediBloc Account
MediBloc has 3 types of accounts, each with a different level of authority and roles within the MediBloc ecosystem:
1)General Users 2)Healthcare Providers Medical practitioners - institutions) 3)Data Researchers (medical researchers, healthcare apps/services).
First of all Healthcare Providers and Data Researchers must be certified.
For general users, there is no access to read or write other Healthcare data accounts except for certain exceptional conditions such as:
Difficulties for the patient to use MediBloc, in these cases the account can be managed by a member of his family, as long as he has the consent of the patient. It also applies to the case of children, in which even though the data is associated with a private key, their parents are the ones who would manage the account.
There are more dramatic cases, such as a serious accident, loss of conscience or any other inconvenient that prevents the patient from transmitting their medical information.
The healthcare consumer may collect vital information about the patient's health (such as blood type, allergy, etc.) for emergency cases like these.
In these circumstances, healthcare providers like paramedics have the right to view this information without approval of the account owner.
Healthcare Provider Credential System
Earlier it was mentioned that all Healthcare Providers and Data Researchers must be certified. This is achieved through the Healthcare Provider Credential System.
This in order to keep the MediBloc platform reliable and make a distinction between general users and health experts.
MediBloc will operate a certification system that is a hybrid of verified decentralization approach and peer-to-peer method, both from trustworthy and certified systems. To increase reliability of the P2P method, the authenticator will deposit to fixed MediPoint (MP) .12
The verification will be rewarded and the intention to deceive the system will be punished and sanctioned. In order to keep the platform free of scams
MediBloc Database
In the current centralized systems of clinical records there is little digital storage space, only a few megabytes. However with the passage of time More and more medical studies show larger data storage, such as high-resolution images, videos or audios.
However, in view of Blockchain's own limitations in terms of storage, MediBloc does not intend to save all medical data in the blockchain.
The data will be store outside of the blockchain and only the hash value of it will be saved in the MediBloc blockchain. MediBloc encrypts data using a private key that can only be decrypted by the owner.
Into your personal device (smartphones, tables, computers, etc). Your device will be the primary data storage. that means all data collected by personal devices will be stand in off blockchain storage.
In the low layer of the MediBloc Platform, the MediBloc Core, a backup will be made to prevent the data loss, The integrity of the stored data can be ver
