Secure Multimedia Retrieval System Using Selective Ordered Bucketization

Bucketization is the splitting of large amount of data into smaller chunks and storing the parts in different sub servers called buckets. This paper deals with ordered bucketization (OB), which makes use of a random key generator algorithm and a deterministic bucketing algorithm, to propose a secure storage and retrieval system for multimedia files. In OB, plaintext-space is split into a number of disjoint buckets, from one to n, based on the ranges covered by them. A bucket number is allotted to each split range in ascending order. Based on the survey on various literature papers, it can be concluded that OB is considered more efficient than order preserving encryption (OPE) in terms of security. Further, asymmetric encryption is used to overcome key related security issues while retrieving the data. While enclosing the proposed method, it is concluded that multimedia retrieval system works effectively for quick retrieval of large multimedia files in a secure manner.
