Secure data parser method and system
View Patent ↗A secure data parser is provided that may be integrated into any suitable system for securely storing and communicating data. The secure data parser parses data and then splits the data into multiple portions that are stored or communicated distinctly. Encryption of the original data, the portions of data, or both may be employed for additional security. The secure data parser may be used to protect data in motion by splitting original data into portions of data that may be communicated using multiple communications paths.
1. A method of managing access to data, the method comprising:
associating, by processing circuitry, a group of users with a volume comprising a plurality of shares stored on a plurality of physical storage devices in a secure data storage network, wherein the volume and the group of users are associated with a workgroup key for providing access to the volume; and
upon determining a user of a client device is a member of the group of users, providing to the user access to the volume.
2. The method of claim 1 , further comprising determining whether the user of the client device is a member of the group of users by assessing user credentials at a secure storage appliance.
3. The method of claim 2 , further comprising receiving the user credentials at the secure storage appliance from an application on the client device.
4. The method of claim 1 , wherein the workgroup key is stored on a remote key server.
5. The method of claim 1 , wherein associating the group of users with the volume occurs on a secure storage appliance.
6. The method of claim 1 , further comprising providing access to the workgroup key to members of the group of users using a secure storage appliance.
7. The method claim 1 , wherein the plurality of shares comprise a plurality of secondary data blocks, and wherein the plurality of secondary data blocks are generated by performing a cryptographic operation on a data set and distributing the data set in the secondary data blocks.
8. A secure storage appliance comprising:
a programmable circuit configured to execute program instructions which, when executed, cause the secure storage appliance to:
associate a group of users with a volume comprising a plurality of shares stored on a plurality of physical storage devices in a secure data network, wherein the volume and the group of users are associated with a workgroup key for providing access to the volume; and
upon determining a user of a client device is a member of the group of users, provide to the user access to the volume.
9. The secure storage appliance of claim 8 , wherein the programmable circuit is further programmed to determine whether the user of the client device is a member of the group of users by assessing user credentials.
10. The secure storage appliance of claim 9 , wherein the programmable circuit is further programmed to receive the user credentials from an application on the client device.
11. The secure storage appliance of claim 8 , wherein the workgroup key is stored on a key server separate from the secure storage appliance.
12. The secure storage appliance of claim 8 , wherein the plurality of shares comprise a plurality of secondary data blocks, and wherein the plurality of secondary data blocks are generated by performing a cryptographic operation on a data set and distributing the data set in the secondary data blocks.
13. A secure data storage network comprising:
a plurality of physical storage devices; and
a secure storage appliance connected to a client device and the plurality of physical storage devices, the secure storage appliance including a programmable circuit configured to execute program instructions which, when executed, cause the secure storage appliance to:
associate a group of users with a volume comprising a plurality of shares stored on the plurality of physical storage devices, wherein the volume and the group of users are associated with a workgroup key for providing access to the volume; and
upon determining a user of the client device is a member of the group of users, provide to the user access to the volume.
14. The secure data storage network of claim 13 , wherein the programmable circuit is further programmed to determine whether the user of the client device is a member of the group of users by assessing user credentials.
15. The secure data storage network of claim 14 , wherein the programmable circuit is further programmed to receive the user credentials from an application on the client device.
16. The secure data storage network of claim 13 , wherein the workgroup key is stored on a key server separate from the secure storage appliance.
17. The secure data storage network of claim 13 , wherein the plurality of shares comprise a plurality of secondary data blocks, and wherein the plurality of secondary data blocks are generated by performing a cryptographic operation on a data set and distributing the data set in the secondary data blocks.
