Cyber Algorithms Report: Security Algorithms for Australian MHR System

This report analyzes cyber security algorithms relevant to the Australian My Health Record (MHR) system. It begins with an introduction outlining the report's purpose: to identify and apply error detection and correction algorithms within the MHR system. The report delves into the MHR system itself, describing its function as a centralized repository for patient health information and its importance in improving healthcare services in Australia. The report then examines key activities within the MHR system, specifically focusing on the login process and adding patient records. The report then explores error detection and correction methods like cyclic redundancy check and RS algorithms, emphasizing their role in ensuring data integrity and confidentiality. The ACID properties, particularly consistency and durability, are discussed in relation to the MHR system's database, alongside the implementation of role-based access control to manage user permissions and data security. Recommendations are provided to enhance the system's security, followed by a conclusion summarizing the findings and emphasizing the importance of authentication measures for patient data protection. The report uses Harvard referencing style.

Introduction
The main aim behind developing the report is to identify the major set of cyber security
algorithms that can be used for the purpose of detecting errors in an application. The report will
focus on applying relevant error detection and correction algorithms on the MHR system. MHR
system is an Australia based website that helps in recording the health condition of the users. this
is a new initiative that is started by Australia for the purpose of storing the patients data effective
at one place. MHR system will be allowing the main stakeholders to communicate effectively in
order to provide better services towards the patients. Thus it is expected that the MHR system
will ensure a better way of providing healthcare facility towards the patients.
About the MHR system
The MHR system is a new initiative that is started by Australia for providing better
services towards the patients. The system will store the necessary details associated with each
patient and will be able to provide better services towards them. Apart from the patient’s data,
MHR will also store details associated with nurses, specialists and doctors. The developed
system will be able to maintain data at one place securely. However the access is only provided
to authenticate persons. The MHR users are the one who has the authority to access the details
related to patient.

Activity 1:
The MHR system is responsible for performing several activities. However this part of
the report will focus on only two major activities. The activities are login to the system and
adding a patient within the system.
The login process is identified one of the important processes for the system. There is a
high need to ensure that proper person is given the access over the system. The main users
associated with MHR system are the users who will be allowed to access the health records
associated with a patient. The patient records can be accessed by the doctors, specialists, patients
and medical receptionist. In order to log in into the system the user must have proper credentials.
The user will be allowed to get into the system only when the credentials are verified by MHR.
The second process that is identified within the MHR system is adding a patient.
Whenever a new patients records are being provided towards the medical receptionist than they
will verify the data and will add the details within the system. As soon as the data of a patient is
added in the MHR system than the doctors and other users of system will be able to access it.
These actions are identified to be one of the important performances thus it is important
to ensure that proper control is maintained over these actions. In case login is provided to
unauthenticated person than it will become difficult to manage the activities. This will eventually
hamper the process and will impact the health records. Moreover they will get the power to
tamper the health records of patients. Thus proper login is needed to be provided towards the
users. This can harm the sensitive data that are stored within the system. The malicious attack
that can occur in response to adding patients within the MHR system is that if any patient data is
stored with inappropriate data than it can hamper the performance of the system. Moreover the if

any newly added patient turns to be fraud one than there is a high chance that the data stored
within the system will get highly impacted.

Activity 2:
Cryptography is the method of encoding and decoding a message for the purpose of
ensuring better confidentiality. With a proper encoding and decoding method it becomes easy to
detect the errors and also ensures that proper measures are provided for correcting these errors.
The major methods that are used for error detection and correction are cyclic redundancy check
and RS algorithm. The RS algorithm helps in controlling the errors that arises while transmitting
a data. This also ensures that the data loss is being maintained effectively so that they can be
used for further transmissions effectively. In the MHR system the cyclic redundancy check
method is being implemented for the purpose controlling the errors that arises at the time of
transmitting data. This method uses an effective way of encoding and decoding the data so that
only authorized person can get the access over the system.
Activity 3
The ACID property states that the system is able to maintain proper atomicity throughout
the data stored. The MHR system focuses on storing the details associated with patients and
hence it becomes essential to ensure that proper security is maintained throughout the MHR
system. While analyzing the MHR system I have analyzed that it satisfies the ACID properties as
it maintains a proper consistency throughout the database. In addition to this the database system
is durable enough for holding all the records effectively and allows users to modify it as per the
needs. This ensures that proper security properties are implemented within the MHR system that
will help in providing better support.

Role based access control is referred to the method that helps in restricting the access that
is provided towards the users of the system. Thus mainly performs its functionality by ensuring
proper authorization technique and ensuring better way of managing the responsibility. The
MHR system has included proper authentication method that will help in managing the data
stored within the system. With proper role based access control it will become easy to manage
the activities. This will ensure that only authorized person are given the access over the data.
Recommendation
The MHR system mainly focuses on storing the data associated with each patient. Hence
it becomes essential to verify the user details and should ensure that only authorized person is
given the access. The system needs to implement proper encryption method that will be capable
of maintaining proper security towards the data.
Conclusion
Thus from the above report it can be concluded that with proper analysis of malicious
attack within the MHR system it is expected that the system will be able to perform efficiently.
The report has explained the two major activities that are taking place within the MHR system.
Along with this the main properties that maintained by MHR system are also explained in the
above parts of the report. Lastly it can be concluded that by implementing proper authentication
measures it will become easy for the system to store the patient’s data. This will ensure that data
are maintained within the system effectively.
