Data integrity proofs in cloud storage Data integrity proofs in cloud storage Presentation Transcript

  • Data Integrity Proofs in Cloud Storage
  • Abstract
    • Cloud storage moves the user’s data to large data centers, which are remotely located, on which user does not have any control. However, this unique feature of the cloud poses many new security challenges which need to be clearly understood and resolved.
    • We provide a scheme which gives a proof of data integrity in the cloud which the customer can employ to check the correctness of his data in the cloud.
  • Existing System
    • As data generation is far outpacing data storage it proves costly for small firms to frequently update their hardware whenever additional data is created. Also maintaining the storages can be a difficult task. It transmitting the file across the network to the client can consume heavy bandwidths.
    • The problem is further complicated by the fact that the owner of the data may be a small device, like a PDA (personal digital assist) or a mobile phone, which have limited CPU power, battery power and communication bandwidth.

  • Disadvantages of Existing System
    • The main drawback of this scheme is the high resource costs it requires for the implementation.
    • Also computing hash value for even a moderately large data files can be computationally burdensome for some clients (PDAs, mobile phones, etc).
    • Data encryption is large so the disadvantage is small users with limited computational power (PDAs, mobile phones etc.).

  • Proposed System
    • We provide a scheme which gives a proof of data integrity in the cloud which the customer can employ to check the correctness of his data in the cloud. This proof can be agreed upon by both the cloud and the customer and can be incorporated in the Service level agreement (SLA).
    • It is important to note that our proof of data integrity protocol just checks the integrity of data i.e. if the data has been illegally modified or deleted.
  • Architecture
  • Advantages of Proposed System
    • Apart from reduction in storage costs data outsourcing to the cloud also helps in reducing the maintenance.
    • Avoiding local storage of data.
    • By reducing the costs of storage, maintenance and personnel.
    • It reduces the chance of losing data by hardware failures.
    • Not cheating the owner.
