Personal Health Records
Personal Health RecordsRRR784 Personal health records (PHRs) have the potential to improve health outcomes but face challenges regarding interoperability, security, and privacy. PHRs could allow individuals to manage their own healthcare by communicating with providers and accessing health information. However, PHRs currently lack standardization and the ability to exchange information between different systems. Addressing issues such as determining security protocols, exchanging data between health information exchanges, and clarifying legal policies will help realize the full benefits of PHRs. Widespread adoption also requires resolving questions over who pays for and controls PHR data. Further research is needed to understand how to best design PHRs and incentivize their use.

PresentationSaikrishna Badrinarayanan The document discusses attribute based encryption and predicate encryption. It summarizes that attribute based encryption allows decryption of a ciphertext only if the attributes in the key match those in the ciphertext. Predicate encryption is a modification where keys are associated with predicates or functions, and a ciphertext can be decrypted if its attribute satisfies the key's predicate. The author's work involved developing predicate based encryption schemes in the public and private key settings, proving their security, and making them more efficient than existing schemes, though relying on stronger assumptions. Future work aims to base the schemes on weaker assumptions and improve efficiency further.

Personal Health Records
Personal Health RecordsAyush Narula An electronic personal health record (EPHR) allows patients to maintain and manage their personal health information privately and securely through an online application. EPHRs are beneficial because they make a patient's health records accessible anytime through mobile devices, which can be crucial in emergencies by providing medical personnel with important health details. While electronic health records are maintained by medical providers, EPHRs are owned by patients. Personal health records can contain a variety of health-related information to help patients and providers manage care. There are two main types of personal health records: standalone PHRs where patients directly input data, and connected PHRs that are linked to provider medical records and allow two-way sharing of information.

Validating a Citizen Observatories enabling Platform by completing a Citizen ...Diego López-de-Ipiña González-de-Artaza Citizen Observatories (COs) are initiatives that empower citizens to engage in data collection, analysis and interpretation in order to address various issues affecting their communities and contribute to policy-making and community development.
Thematic co-exploration is a co-production process where citizens actively participate alongside scientists and other actors in the exploration of specific themes.
Making them a reality involves addressing the following challenges:
Data quality and reliability
Engagement and retention of participants
Integration with policy and decision-making

Scalable and secure sharing of public health record using attribute based Encryption
- 1. SCALABLE AND SECURE SHARING OF PERSONAL HEALTH RECORDS IN CLOUD COMPUTING USING ATTRIBUTE BASED ENCRYPTION By Shreyank M. Byadagi Email:[email protected]
- 2. AGENDA: 1. Objectives of project. 2. Problem definition. 3. Literature survey. 4. Methodology. 5. Applications. 6. Implementation carried out. 7. References.
- 3. OBJECTIVES: • The main aim of this system is to provide secure patient- centric PHR access and efficient key management at the same time. • The key idea is to divide the system into multiple security domains according to the different users’ data access requirements.
- 4. PROBLEM DEFINITION: Personal health record(PHR) is meant for health information exchange , this data is outsourced for maintenance like cloud providers. CHALLENGES : • PHR data is prone to unauthorized access. • Access needs to be secure. OUR SOLUTION: • Attribute Based Encryption(ABE) techniques are used to encrypt patient’s PHR file. • A high degree of patient privacy guaranteed.
- 5. LITERATURE SURVEY: • J. Benaloh, proposed a scheme “Patient Controlled Encryption: Ensuring Privacy of Electronic Medical Records,” in which a file can be uploaded without key distribution and it is highly efficient. • J. Hur and D. K. Noh proposed a scheme “Attribute-Based Revocation in Data Outsourcing Systems” with immediate capability, instead of periodical revocation.
- 8. ER-Diagram:
- 9. EXISTING SYSTEM: • Due to the high cost of building and maintaining specialized data centers, many PHR services are outsourced . • The main concern is about whether the patients could actually control the sharing of their sensitive personal health information (PHI), especially when they are stored on a third- party server which people may not fully trust.
- 10. EXISTING SYSTEM(Contd…): Hey, I got it !! Lets modify & send!!!
- 11. PROPOSED SYSTEM: • It is the promising method to encrypt the PHRs before outsourcing. • Risks of privacy exposure , scalability in key management , flexible access are important challenges towards data access control. • Attribute Based Encryption(ABE) techniques are used to encrypt patient’s PHR file.
- 13. ALGORITHMS: • Advanced Encryption Standard(AES) • Message Digest5(MD5)
- 14. ADVANCED ENCRYPTION STANDARD: • Step1:Substitute bytes. • Step2. Shift rows. • Step3. Mix Columns. • Step4. Add Round Key
- 16. Contd….
- 20. MESSAGE DIGEST5(MD5): • Step1: Append padding bits: Message is pad so its length is 448 mod 512 • Step2: Append Length Append a 64-bit length value to message Generate a message with 512 bits in length • Step3: Initialize MD buffer Initialize a 4-word (128-bit) MD buffer (A, B, C, D) Word A: 01 23 45 67 Word B: 89 AB CD EF Word C: FE DC BA 98 Word D: 76 54 32 10 • Step4: Process Message in 16-word block Process message in 16- word (512-bit) blocks • Step5: Output
- 21. Difference B/W: Existing System: 1. Expensive to maintain many PHR services. 2. Patient rejects to share his PHI as it is stored in third party server. Proposed System: 1. Inexpensive to create and maintain PHR services. 2. Patient shares his PHI as it is encrypted using ABE technique before it is stored in third party server.
- 23. APPLICATIONS: • Hospital Management. • Health Care Website.
- 24. MODULES: • PHR Owner module • Cloud Server Module • Attribute based Access Policy Module • Data confidentiality Module Front end of our project is prepared with the help of JSP.
- 25. REQUIREMENTS: HARDWARE REQUIREMENTS:- • Processor - Pentium –III • Speed - 1.1 Ghz • RAM - 256 MB(min) • Hard Disk - 20 GB • Floppy Drive - 1.44 MB • Key Board - Standard Windows Keyboard • Mouse - Two or Three Button Mouse • Monitor - SVGA
- 26. REQUIREMENTS(CONTD..) SOFTWARE REQUIREMENTS:- • Operating System : Windows95/98/2000/XP • TOOL USED : ECLIPSE • Front End : JAVA
- 27. REFERENCES: • M. Li, S. Yu, K. Ren, and W. Lou, “Securing personal health records in cloud computing: Patient-centric and fine-grained data access control in multi-owner settings”. • H. Lohr, A.-R. Sadeghi, and M. Winandy, “Securing the e- health cloud”. • “The health insurance portability and accountability act”.
