A Novel File Compression Mechanism based on Multi-Authority CP-ABE for Fine Grained Access Control
Abstract
Within the compositions, here witnessed within healthcare zone, developing request along with assumption about software program evolution within the cloud computing toward deal to contemporary as well as further needs of health related facilities. Within the document, we suggest comfortable, fee effective along privacy protected cloud-based structure to health related domain. We endorse comfortable as well as effictive structure toward authorities EHR device, wherein first-rate-grained get admission to be able to provide primarily base on multi-authority ciphertext attribute-primarily base encryption (CP-ABE), together through a hierarchical shape, toward enforce get right of entry to manage rules. The planned structure can permit selection makers inside the Kingdom of Saudi Arabia to broaden healthcare quarter to current e-authorities cloud computing platform ―Yasser, which be answerable intended to handing over shares offerings via surprisingly green, dependable, as well as secure surroundings. This design objectives toward gives fitness services along with facilities through the government toward citizens (G2C). Here all patients’ data will be stored at cloud and cloud servers will cost government based on the hard disk size used to store patient data. If users are uploading heavy files then cloud will occupy more space and cost will be more. As a extension concept, To further reduce storage cost we can compress encrypted file to reduce it size. When user downloading files then we will decompress. So by using compression technique in extension work we can save some cloud storage cost. If much free space available then cloud processing speed will also be high.
