A Practical Framework for Executing Complex Queries over Encrypted Multimedia Data
Over the last few years, data storage in cloud based services has been very popular due to easy management and monetary advantages of cloud computing. Recent developments showed that such data could be leaked due to various attacks. To address some of these attacks, encrypting sensitive data before sending to cloud emerged as an important protection mechanism. If the data is encrypted with traditional techniques, selective retrieval of encrypted data becomes challenging. To address this challenge, efficient searchable encryption schemes have been developed over the years. Almost all of the existing searchable encryption schemes are developed for keyword searches and require running some code on the cloud servers. However, many of the existing cloud storage services (e.g. Dropbox (https:/www.dropbox.com) Box (https:/www.box.com/ Google Drive (http:/drive.google.com/ etc. only allow simple data object retrieval and do not provide computational support needed to realize most of the searchable encryption schemes.
