Abstract:
1. A method to secure data read from a storage device before the data is passed to a network, comprising: reading data from the storage device before the data is passed to the network; examining, with an electronic device, the data read from the storage device to identify header information that indicates whether the data is either compressed or uncompressed; identifying the data as either compressed or uncompressed based on the examination of the header information; evaluating the data to determine whether the data read from the storage device is in encrypted form or whether the data read from the storage device is in unencrypted form; passing the data read from the storage device without further encryption in response to determination that the data read from the storage device is in encrypted form so as to avoid double encryption of the data; encrypting the data read from the storage device in response to determination that the data read from the storage device is not in encrypted form; passing the encrypted data to the network; and storing the encrypted data in a cache.
