Abstract
Official abstract text for this publication.
A mechanism is provided which allows to de-duplicate encrypted data such that the de-duplication ratio for encrypted data is similar to the de-duplication ration of the corresponding un-encrypted data and the purpose of encryption is not obfuscated, i.e. only the originator of the data (the client) can decrypt—and hence read—the data. This is achieved by interwoven the de-duplication algorithm with the encryption algorithm in a way that the data are encrypted with a key that is generated from the unencrypted data. Afterwards, that key is itself encrypted with an encryption key being private to a particular client. Due to the fact that the private key is not effecting the encrypted data stream, it can still be de-duplicated efficiently.
First claim
Opening claim text (preview).
The invention claimed is: 1. A computer program product comprising a non-transitory computer readable storage medium having a computer readable program stored therein for backing-up data within a computer environment, wherein the computer readable program, when executed on a computing device, causes the computing device to: store a client file within a client repository on a client device; split, in a deterministic way the client file into chunks of data; generate a client has…
