Improvement of Deduplication Efficiency by Two Layers Deduplication System
IEEJ Transactions on Electronics, Information and Systems, 2014SUMMARYThis paper proposes a two‐layer deduplication system for the backup process in an IT environment. The proposed system implements two chunk sizes in a descendent way and activates them simultaneously in a sequence. They eliminate duplicated parts among backup target data more efficiently than any conventional single‐layer deduplication system ...

Metadedup: Deduplicating Metadata in Encrypted Deduplication via Indirection
2019 35th Symposium on Mass Storage Systems and Technologies (MSST), 2019Encrypted deduplication combines encryption and deduplication in a seamless way to provide confidentiality guarantees for the physical data in deduplication storage, yet it incurs substantial metadata storage overhead due to the additional storage of keys.

2017 IEEE 16th International Symposium on Network Computing and Applications (NCA), 2017
Video content makes up more than half of the world's Internet traffic, and this figure is expected to grow rapidly. New techniques that remove traffic redundancy have been shown to significantly improve network performance since many concurrent streams deliver the same video. These techniques employ smart routers that recognize duplicated video streams

Demystifying data deduplication
Proceedings of the ACM/IFIP/USENIX Middleware '08 Conference Companion, 2008Effectiveness and tradeoffs of deduplication technologies are not well understood -- vendors tout Deduplication as a "silver bullet" that can help any enterprise optimize its deployed storage capacity. This paper aims to provide a comprehensive taxonomy and experimental evaluation using real-world data.

Adaptive pipeline for deduplication
012 IEEE 28th Symposium on Mass Storage Systems and Technologies (MSST), 2012Deduplication has become one of the hottest topics in the field of data storage. Quite a few methods towards reducing disk I/O caused by deduplication have been proposed. Some methods also have been studied to accelerate computational sub-tasks in deduplication.

Deduplicating a places database
Proceedings of the 23rd international conference on World wide web, 2014We consider the problem of resolving duplicates in a database of places, where a place is defined as any entity that has a name and a physical location. When other auxiliary attributes like phone and full address are not available, deduplication based solely on names and approximate location becomes an exceptionally challenging problem that requires ...

Online Deduplication for Databases
Proceedings of the 2017 ACM International Conference on Management of Data, 2017dbDedup is a similarity-based deduplication scheme for on-line database management systems (DBMSs). Beyond block-level compression of individual database pages or operation log (oplog) messages, as used in today's DBMSs, dbDedup uses byte-level delta encoding of individual records within the database to achieve greater savings.

Distributed data deduplication
Proceedings of the VLDB Endowment, 2016Data deduplication refers to the process of identifying tuples in a relation that refer to the same real world entity. The complexity of the problem is inherently quadratic with respect to the number of tuples, since a similarity value must be computed for every pair of tuples.

Transparent Data Deduplication in the Cloud
Proceedings of the 22nd ACM SIGSAC Conference on Computer and Communications Security, 2015Cloud storage providers such as Dropbox and Google drive heavily rely on data deduplication to save storage costs by only storing one copy of each uploaded file. Although recent studies report that whole file deduplication can achieve up to 50% storage reduction, users do not directly benefit from these savings-as there is no transparent relation ...

Entity Deduplication on ScholarlyData
2017ScholarlyData is the new and currently the largest reference linked dataset of the Semantic Web community about papers, people, organisations, and events related to its academic conferences. Originally started from the Semantic Web Dog Food (SWDF), it addressed multiple issues on data representation and maintenance by (i) adopting a novel data model ...
