• Cloud Computing consists of hardware and

software resources made available on the Internet as managed third-party services.

• These services are typically provide access to advanced software applications and high-end

networks of server computers.

What is Cloud Computing?

What is the use of it?

• There are a number of reasons why cloud computing is so widely used among

businesses today some are: Reduction of cost. Universal access. Flexibility.

Examples of Cloud Computing

• Many popular social networking sites such as FaCeBoOk, PiCaSa, and YoUtUbE are also often considered parts of cloud computing.

What is Attribute-based Encryption

• It is a type of public - key encryption in which the secret key of a user and the

cipher text are dependent upon attributes (e.g. the country he lives, the subscriber

he uses). • In such a system , the decryption of a

cipher text is possible only if the set of attributes of the user key matches the

attributes of the cipher text.

Introduction

• This webpage is to secure the personal and medical information of the

patient using encryption.• Here we have an option of visibility... that means we can access the permission

for particular member to visit or to see the status of the person(patient), that is

nothing but ACCESS POLICY.

Existing system

• The existing system stores the information in files.• That is personal and medical information.• The entire details about the user or patient are stored, in written type or any printed papers.• By this we may face many.

Disadvantages

• By storing the information in files it can be exposed to the third party or unauthorized

parties.• By secretly any one can access it this is the

main disadvantage of the existing system.• It occupies more space.

• High cost as it requires more space to store the files.

Proposed system

• Here we use system memory to store the personal and medical information of the

person.• Here we use one technique to avoid risk like

accessing the information of the particular person via network analysis and that is

ATTRIBUTE –BASED ENCRYPTION.

Advantages

• No can access the information of a person as it is encrypted by a secret key.

• To see any report about the person … him self should login into the webpage and

access the information.• Every user as unique user name and

password that is known only to him.•User as an option to access the information

for whom ever he needed.

Conclusion

All patient data should be gathered and accessible through one system.

A PHR applies health information technology to your personal life to improve safety, reduces medical errors, reduces gaps

in communication and reduce delays in receiving proper care.
