Detection of sensitive personal information in a storage device

A computer program product for detecting sensitive personal information in a storage device, the computer program product comprising one or more computer readable storage mediums having program code embodied therewith, the program code comprising the programming instructions for:

• processing a block delta list, wherein said block delta list is a list of changed blocks in a storage device, wherein said block delta list includes deltas associated with said changed blocks that indicate differences in said changed blocks from a first point of time to a second point of time;
• identifying changed blocks from said block delta list;
• searching said identified changed blocks for sensitive personal information using a character scanning technique;
• identifying a changed block deemed to contain said sensitive personal information;
• and
• translating said identified changed block from a block level to a file level using a hierarchical reverse mapping technique.

A system, comprising:

• a memory for storing a computer program for detecting sensitive personal information in a storage device;
• and
• a processor connected to said memory, wherein said processor is configured to execute the program instructions of the computer program comprising:
• processing a block delta list, wherein said block delta list is a list of changed blocks in a storage device, wherein said block delta list includes deltas associated with said changed blocks that indicate differences in said changed blocks from a first point of time to a second point of time;
• identifying changed blocks from said block delta list;
• searching said identified changed blocks for sensitive personal information using a character scanning technique;
• identifying a changed block deemed to contain said sensitive personal information;
• and
• translating said identified changed block from a block level to a file level using a hierarchical reverse mapping technique.
