Abstract EN
Many of cloud service providers pretend that user's data is saved securely with no data integrity violation.
But as we know, anything saved in the internet environment can't be perfectly safe which reduce users trust that their files in safe situation, then they can’t store sensitive data in the cloud.
In this work, we work on the problem of integrity of shared data over the cloud and a new model was built with dynamic data operation support.
This model contains an intermediate system to detect file integrity violation by hashing the file, using SHA-256 algorithm, before saving it on the cloud and after retrieving it, then compare the two hash values.
Several experiments were conducted to ensure the ability of detecting data integrity violation, different sizes of .doc files starting from 13KB, ending with 5MB were collected.
On the other hand, different types of tests were conducted to evaluate the accuracy and concurrent access.
The evaluation process proves that our intermediate system is able to guarantee Files accuracy and detect many types of file modifications.
Also, it is able to organize concurrent access operations on shared file and enable just one user to modify File at the same point.
