Deduplication Research In Cloud Storage Environment

With the advancement of information technology,in recent years,artificial intelligence,neural network and other technologies have occupied a leading position.These advanced technologies need to rely on a large amount of data.How to manage these data will become an important point of technological breakthrough,and thus,cloud storage technology is highly regarded by technology groups or organizations and is an important part of data storage technology.With the increase of cloud storage scal e,we are facing the problem of storage space data redundancy.How to delete redundant data and improve the utilization of cloud storage space will become our main concern.Nowadays,the mainstream cloud storage data deduplication technology can safely delete redundant encrypted data.The technology can be mainly divided into file-level data deduplication and file block-level data deduplication according to the type of the file.However,neither of these technologies can achieve dynamic deduplication and cannot meet operational requirements in actual operation.Based on the aforementioned problems,this paper mainly studies the deduplication of cloud data,an efficient and safe dynamic de-duplication scheme and a fuzzy de-duplication scheme for medical data are designed.The results of this paper will be the following two aspects:1?Combining the data structure of the linked list,use its excellent and perfect memory management mechanism and operational convenience,it ensures a set of data de-duplication solutions that can be used in the cloud under the premise of low performance consumption during use.For the changed file block,the redundant part of the file can be removed dynamically safely and efficiently,and the storage space of the cloud server is released.2?According to the characteristics of medical data and the usage habits of medical institutions for patient data,the existing storage mechanism is deeply studied.Then,combined with characteristics of medical data,a fuzzy deduplication scheme suitable for medical cloud is proposed,which realizes the management mechanism of medical data storage,which can quickly replace data content and ensure the confidentiality of medical data.
