gnuhealth-crypto 5.0.3

Basic cryptographic and signature methods for GNU Health HIS

Cryptography package for GNU Health HIS

The health-crypto package provides basic methods and models to enhance confidenciality, integrity and non-repudiation in GNU Health Hospital Management System

The health_crypto module will provide the following functionality :

Document Serialization Document hashing (MD) Document signing Document verification Document encryption

The module will work on records from models that will need this functionality such as prescription, patient evaluations, surgeries or lab tests.

The Serialization process will include the information in a predefined format (JSON) and encoding (UTF8).

There will be a field that will contain the Message digest of the serialization process, and that will check for any changes.

The signing process will be upon that Message Digest field, whereas the encryption process will work on row or column level.

Public key / asymmetric cryptography will be used for signing the documents.

About GNU Health HIS, the Libre Hospital Information System

Welcome to the Hospital Information System (HIS) of GNU Health!

The main areas of the HIS are:

• Demographics and Community: Individuals, domiciliary units, families, socioeconomics, demographic & administrative information

• Patient Management: Health encounters and evaluations, hospitalizations, clinical history and other information that makes up the electronic medical records (EMR)

• Health Center: Finances & billing, stock & pharmacy, staff, suppliers, beds, operating rooms and other relevant tasks to manage the health center

• Laboratory and Medical Imaging: Management of complementary orders such as lab tests, medical and diagnostic imaging requests and workflows

• Health Information System: Statistics, analytical reporting on collected data from the community and participating health institutions, e.g. demographics and epidemiology

Functionalities of specific modules are briefly summarized over here:

The GH HIS is part of the GNU Health project, the Libre digital health ecosystem.

The GNU Health project combines the daily medical practice with state-of-the-art technology in bioinformatics and genetics. It provides a holistic approach to the person, from the biological and molecular basis of disease to the social and environmental determinants of health.

The GNU Health Hospital Management component integrates with the GNU Health Federation, which allows to interconnect heterogeneous nodes and build large federated health networks across a province, country or region.

Need help to implement GNU Health ?

We are committed to do our best in helping out projects that can improve the health of your country or region. We want the project to be a success, and since our resources are limited, we need to work together to make a great and sustainable project.

First place to ask for support are the mailing lists & matrix chat:

https://docs.gnuhealth.org/his/support.html#online-resources

Feel free to contact us directly if this does not suffice or if you need custom support. In order to be elegible, we need the following information from you, your NGO or government:

• An introduction of the current needs

• The project will use free software, both at the server and workstations

• There will be a local designated person that will be in charge of the project and the know-how transfer to the rest of the community.This person must be committed to be from the beginning of the project until two years after its completion.

• There must be a commitment of knowledge transfer to the rest of the team.

We will do our best to help you out with the implementation and training for the local team, to build local capacity and make your project sustainable.

Please contact us and we’ll back to you as soon as possible:

Thank you !
