A tunable proof of ownership scheme for deduplication using Bloom filters

Jorge Blasco, Roberto Di Pietro, Agustin Orfila, Alessandro Sorniotti
2014 2014 IEEE Conference on Communications and Network Security  
Deduplication is a widely used technique in storage services, since it affords a very efficient usage of resources-being especially effective for consumer-grade storage services (e.g. Dropbox).  ...  In this paper, we introduce a novel solution based on Bloom filters that provides a flexible, scalable, and provably secure solution to the weaknesses of deduplication, and that overcomes the deficiencies  ...  Bloom filters have been successfully used in other domains of computer security [10] . However, to the best of our knowledge, they have never been applied to proof of ownership schemes.  ...

Revocable attribute-based encryption scheme with efficient deduplication for eHealth systems

Hua Ma, Ying Xie, Jianfeng Wang, Guohua Tian, Zhenhua Liu
2019 IEEE Access  
In this paper, we propose a variant of the attribute-based encryption scheme that supports efficient deduplication and attributes revocation for eHealth systems.  ...  However, the excessive computation costs of existing schemes lead to inefficient deduplication.  ...  [30] put forward a clever idea, named bloom filter proof of ownership (BF-PoW), to give a flexible, scalable, and provably secure method.  ...

‏An Enhanced Approach to Improve the Security and Performance for Deduplication

Nourah Almrezeq Et al.
2021 Turkish Journal of Computer and Mathematics Education  
That is what drives us to suggest a method for removing duplicate data that is both performance and security effective.  ...  Via the use of the AES-CBC algorithm and hashing functions, we have proposed an enhancement to improves the performance and protection of data de-duplication for users.  ...  Acknowledgements The authors would like to thank the Deanship of Graduate Studies at Jouf University for funding and supporting this research through the initiative of DGS, Graduate Students Research Support  ...

Instead, we design BFSMinHash, a Bloom-filter sketching scheme for Minhash, which uses a single hash function.  ...  The Bloom filter is a space efficient data structure which can be used to test whether an element is in a set. However, when we adopt Bloom filter, we have to tolerate its effect of false positives.  ...  model; Data summarization task for social media data from Twitter.  ...
