A secure authorized deduplication scheme for cloud data based on blockchain
Information Processing and Management, 2021Abstract Deduplication scheme based on convergent encryption (CE) is widely-used in cloud storage system to eliminate redundant data. However, the adversaries can obtain the data by the brute-force attack, if the data belongs to a predictable set for CE.

A Hybrid Cloud Approach for Secure Authorized Deduplication
IEEE Transactions on Parallel and Distributed Systems, 2015Data deduplication is one of important data compression techniques for eliminating duplicate copies of repeating data, and has been widely used in cloud storage to reduce the amount of storage space and save bandwidth. To protect the confidentiality of sensitive data while supporting deduplication, the convergent encryption technique has been proposed ...

Image And Text Encrypted Data With Authorized Deduplication In Cloud
2020 International Conference on System, Computation, Automation and Networking (ICSCAN), 2020In this paper, the role re-encryption is used to avoid the privacy data lekage and also to avoid the deduplication in a secure role re-encryption system(SRRS). And also it checks for the proof of ownership for to identify whether the user is authorized user or not. This is for the efficiency.

Survey on techniques for Authorized Deduplication of Encrypted data in Cloud
2020 International Conference on Computer Communication and Informatics (ICCCI), 2020Cloud computing technology is on-demand nowadays. Number of files created, stored and processed in cloud is increasing per day. The amount of space, processing power, bandwidth and cost requirement is quiet high. It is been observed that more than half of the data generated and stored on the cloud is duplicate.

An enhanced approach for securing authorized deduplication in hybrid clouds
2016 International Conference on Communication and Electronics Systems (ICCES), 2016Cloud computing enables new business models and cost effective resource usage. In Cloud Computing Technology Data Storing and Data Sharing plays a major role. In Data Storing we face a main problem of Data deduplication. Various traditional deduplication systems are introduced for elimination of replicate check besides the data itself, but existing ...

A review of hilevel authorized deduplication method for cloud storage system
2016 3rd International Conference on Advanced Computing and Communication Systems (ICACCS), 2016The data storage management is the biggest problem in the cloud computing environment. To reduce the storing space and save the bandwidth share the data with others in cloud storage using public-key cryptosystems that produce constant-size cipher texts such that the active delegation of decoding rights for any set of cipher texts but it lead to many ...

Data deduplication is the technique of reduction in the data which keeps only one physical copy and generates pointers to that copy for referencing other redundant data. To secure the confidentiality of private data throughout deduplication, the convergent cryptography technique is used to encode the information before uploading it onto the general ...
