People and businesses are more often than ever storing large amounts of private data in \u2018the cloud\u2019 with storage service providers. To protect their clients\u2019 private information, this stored data is encrypted so that no one, including the service providers, can read it. But this makes it impossible for cloud storage providers to efficiently manage that data and provide their clients with better storage capacity. Research sponsored by a multinational IT service provider in 2010 suggested that up to 75% of all produced data is duplicated. Owners of an open source \u2018deduplication\u2019 solution suggest that reducing duplicate data could clear up to 95% of storage space.<\/span><\/p>\n

For cloud storage providers to remove, or \u2018deduplicate\u2019, data, they need to be able to recognize it without infringing on their clients\u2019 privacy. Now, researchers at the Agency for Science, Technology and Research (A*STAR) Data Storage Institute in Singapore have developed a system that allows cloud storage providers to do just that.<\/span><\/p>\n

The system, called HEDup, involves the use of a separate \u2018key server\u2019, which assigns a secure key to the data that will be encrypted and then uploaded for storage on the cloud\u2019s server. The service provider, such as Dropbox or Gmail, can then employ \u2018homomorphic encryption\u2019, which involves carrying out computations on the encrypted text, to detect information from the data\u2019s secure key. This allows the provider to determine, without actually reading the original data, whether it is a duplicate. Duplicate data will have the same key, which can only be accessed for encryption and decryption purposes by data owners.<\/span><\/p>\n

The team tested its system and found that it increased the uploading time of a 16-megabyte file, which normally takes an average of 5.22 seconds, by 1.4 seconds. It also increased the downloading time by only 0.4 seconds.<\/span><\/p>\n

The team next plans to improve the security of the key server and to develop a method for clients to upload and download data from multiple devices without the need for manually providing their private key for its encryption and decryption.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
