Product Description

Aim:    
           The main aim of this project is to achieve
new distributed de-duplication systems we present an attribute-based storage system with secure deduplication in a hybrid cloud setting with higher reliability.

 

Synopsis:

              In this Deduplication techniques are most widely employed to backup data and minimize network and storage overhead by detecting and eliminating redundancy among data. so which is crucial for eliminating duplicate copies of identical data in order to save storage space and network bandwidth.


               We present an attribute-based storage system with secure deduplication in a hybrid cloud setting, using public cloud and private cloud. Where a private cloud is responsible for duplicate detection and a public cloud manages the storage. Instead of keeping multiple data copies with the same content, in this system eliminates redundant data by keeping only one physical copy and referring other redundant data to that copy.
Each such copy can be defined based on  user access policies, In the user will upload the file with access policies and then file type question with answer. Then same file with different access policies to set the particular file to replace the reference.  Where a user’s private key is associated with an attribute set, a message is encrypted under an access policy over a set of attributes, and a user can decrypt a cipher text with his/her private key if his/her set of attributes satisfies the access policy associated with this cipher tex. Our system has two advantages. Firstly, we use two level of checking file (i.e., file level deduplication), and (signature match checking).To applying deduplication to user data to save maintenance cost in HDFS. We reduced the time and cost in uploading and downloading with storage space in hadoop system.


Proposed System:

                  In this paper, we present an attribute-based storage system which employs ciphertext-policy attribute-based encryption (CP-ABE) and supports secure deduplication. To enable the deduplication and distributed storage of the data across HDFS.And then using two way cloud in our storage system is built under a hybrid cloud architecture, where a private cloud manipulates the computation and a public cloud manages the storage. The private cloud is provided with a trapdoor key associated with the corresponding ciphertext, with which it can transfer the ciphertext over one access policy into ciphertexts of the same plaintext under any other access policies without being aware of the underlying plaintext. After receiving a storage request, the private cloud first checks the validity of the uploaded item through the attached proof. If the proof is valid, the private cloud runs a tag matching algorithm to see whether the same data underlying the cipher text has been stored. If so, whenever it is necessary, it regenerates the ciphertext into a ciphertext of the same plaintext over an access policy which is the union set of both access policies.like public cloud and private cloud. We have shown the concept of deduplication effectively and security is achieved by means of Proof of Ownership of the file. That is attribute-based storage system ciphertext-policy attribute-based encryption (CP-ABE) and supports secure deduplication

When you order from finalyearprojects.in, you will receive a confirmation email. Once your order is shipped, you will be emailed the tracking information for your order's shipment. You can choose your preferred shipping method on the Order Information page during the checkout process.

The total time it takes to receive your order is shown below:

The total delivery time is calculated from the time your order is placed until the time it is delivered to you. Total delivery time is broken down into processing time and shipping time.

Processing time: The time it takes to prepare your item(s) to ship from our warehouse. This includes preparing your items, performing quality checks, and packing for shipment.

Shipping time: The time for your item(s) to tarvel from our warehouse to your destination.

Shipping from your local warehouse is significantly faster. Some charges may apply.

In addition, the transit time depends on where you're located and where your package comes from. If you want to know more information, please contact the customer service. We will settle your problem as soon as possible. Enjoy shopping!
