View Edit Delete	US8762658B2	In one embodiment, the secure erase module 1320 overwrites the existing data each time a data segment token is stored. In another embodiment, the storage request specifically includes a request to overwrite the existing data and the secure erase module 1320 overwrites the existing data in response to the request to overwrite the existing data. In another embodiment, the secure erase module 1320 stores metadata information regarding confirmation that the existing data has been erased so that subsequent reads can indicate the erasure.	278	Added by DJM 3 2021	3/24/21, 12:00 AM
View Edit Delete	US8762658B2	In other embodiments where a secure erase is not received, the existing data is deleted. In one embodiment, deleting the data includes deleting an index entry, address, etc. In a preferred embodiment, the when a data segment token is stored, the corresponding existing data is marked as invalid or otherwise ready for storage recovery. The data may be later recovered in a storage recovery operation, garbage collection operation, etc.	279	Added by DJM 3 2021	3/24/21, 12:00 AM
View Edit Delete	US8762658B2	In a particular embodiment, the apparatus includes a read request receiver module 1308 that receives a storage request to read the data segment, a read data segment token module 1310 that reads the data segment token corresponding to the data segment requested by the storage request, and a read request response module 1312 that transmits a response to the requesting device 1326. The response is generated using the data segment token corresponding to the requested data segment.	280	Added by DJM 3 2021	3/24/21, 12:00 AM
View Edit Delete	US8762658B2	The storage request to read the data segment, in one embodiment, is associated with the storage request and serves to confirm that the storage request has been successful. In another embodiment, the request to read the data segment is independent from the storage request and may be initiated by the requesting device 1326 that made the storage request or another separate requesting device 1326.	281	Added by DJM 3 2021	3/24/21, 12:00 AM
View Edit Delete	US8762658B2	In one embodiment, where the requesting device 1326 is capable of receiving information from the data segment token in place of actual data, the read request response module 1312 includes a transmit data segment token module 1314 that transmits in the response a message to the requesting device 1326. The message includes at least the data segment identifier and the data segment length, but may also include a data segment location, at least one instance of the repeated, identical character or character string, or other pertinent information. Typically, the message does not include the actual data of the data segment, other than what is included in the data segment token.	282	Added by DJM 3 2021	3/24/21, 12:00 AM
View Edit Delete	US8762658B2	In the depicted embodiment, the modules 1302-1324 are included in the storage device 150 or storage controller 152. In another embodiment, at least a portion of one or more of the modules 1302-1324 is located outside the storage device 150. In a further embodiment, the requesting device 1326 includes a portion of the modules 1302-1324 in the form of drivers, software, or other function of one or more of the modules 1302-1324. For example, a token generation module 1306 and a reconstitute data segment module 1318 are shown in the requesting device 1326. One of skill in the art will recognize other ways to distribute and implement the functionality of the modules 1302-1324.	268	Added by DJM 3 2021	3/24/21, 12:00 AM
View Edit Delete	US8762658B2	In one embodiment, the system 1300 includes a separate apparatus that includes a read request receiver module 1308, a read data segment token module 1310, a read request response module 1312, which are substantially similar to those described above. The apparatus may be independent from the apparatus including the write request receiver module 1302 and the data segment token storage module 1304. In one embodiment, the read request response module 1312 includes a transmit data segment token module 1314 and/or a transmit data segment module 1316, and the apparatus may include a reconstitute data segment module 1318, where the modules 1314, 1316, 1318 are substantially similar to those described above.	284	Added by DJM 3 2021	3/24/21, 12:00 AM
View Edit Delete	US8762658B2	FIG. 14 is a schematic flow chart diagram illustrating an embodiment of a method 1400 for storing a data segment token in accordance with the present invention. The method 1400 begins 1402 and the write request receiver module 1302 receives 1404 a storage request from the requesting device 1326, where the storage request includes a request to store a data segment in the storage device 150. The data segment includes a series of repeated, identical characters or character strings. The data segment token storage module 1304 stores 1406 a data segment token in the storage device 150 and the method 1400 ends 1408. The data segment token includes at least a data segment identifier and a data segment length and the data segment token does not include data from the data segment for the most part.	285	Added by DJM 3 2021	3/24/21, 12:00 AM
View Edit Delete	US8762658B2	FIG. 15 is a schematic flow chart diagram illustrating an embodiment of a method 1500 for reading a data segment token in accordance with the present invention. The method 1500 begins 1502 and the read request receiver module 1308 receives 1504 a storage request to read a data segment from the storage device 150. The data segment is represented on the storage device 150 by a data segment token and the data segment includes a series of repeated, identical characters or character strings. The data segment token includes at least a data segment identifier and a data segment length and the data segment token does not include data from the data segment. The read data segment token module 1310 reads 1506 the data segment token corresponding to the data segment requested in the storage request, the read request response module 1312 transmits 1508 a response to the requesting storage device 150 and the method 1500 ends 1510. The response is generated using the data segment token corresponds to the requested data segment.	286	Added by DJM 3 2021	3/24/21, 12:00 AM
