Abstract

A method of extracting unclassified data from a collection of data including both classified data and unclassified data, includes: providing a plain text format file including a plurality of attributes; using the attributes to identify unclassified data within a collection of data that includes a combination of unclassified and classified data; and extracting the identified unclassified data from the collection of data. An apparatus that implements the method is also provided.

Claims

1. A method of extracting unclassified data from a collection of data including both classified data and unclassified data, the method comprising:

providing a plain text format file including a plurality of attributes;

using the attributes to identify unclassified data within a collection of data that includes a combination of unclassified and classified data; and

extracting the identified unclassified data from the collection of data.

2. The method of claim 1, wherein the format files describe a data structure per message type and include security marks.

3. The method of claim 1, wherein the collection of data includes binary files and the binary files are filtered on both variable type and bit wise levels in accordance with security marks provided in format files.

4. The method of claim 1, wherein the collection of data follows a defined data structure criteria that is consistent with system description documentation.

5. The method of claim 4, wherein a message structure of files in the collection of data are described by an Object Management Group Interface Description Document Language.

6. The method of claim 1, wherein the collection of data includes nested data.

7. The method of claim 1, wherein the step of using the attributes to identify unclassified data is implemented using a software tool that extracts, decodes, and filters the identified unclassified data and stores the unclassified data in plain text files.

8. The method of claim 8, wherein the software tool is independent of data structures in the collection of data.

9. The method of claim 9, wherein the software tool uses the attributes to decode message reports written into a binary file.

10. An apparatus comprising:

a classified environment including a collection of data including both classified data and unclassified data;

a plain text format file including a plurality of attributes;

an application configured to use the attributes to identify and extract unclassified data from the collection of data; and

an unclassified environment including a memory configured to receive the extracted unclassified data.

11. The apparatus of claim 10, wherein the format files describe a data structure per message type and include security marks.

12. The apparatus of claim 10, wherein the collection of data includes binary files and the application is configured to filter the binary files on both variable type and bit wise levels in accordance with security marks provided in format files.

13. The apparatus of claim 10, wherein the collection of data follows a defined data structure criteria that is consistent with system description documentation.

14. The apparatus of claim 13, wherein a message structure of files in the collection of data are described by an Object Management Group Interface Description Document Language.

15. The apparatus of claim 10, wherein the identified unclassified data is placed in plain text files.

16. The apparatus of claim 10, wherein the collection of data includes nested data.

17. The apparatus of claim 10, wherein the application is configured to extract, decode, and filter the identified unclassified data and stores the unclassified data in plain text files.

18. The apparatus of claim 17, wherein the application is independent of data structures in the system.

19. The apparatus of claim 17, wherein the application is configured to use the attributes to decode message reports written into a binary file.

20. A method of extracting data having an identified classification level from a collection of data including both data having the identified classification level and data having a higher classification level, the method comprising:

providing a plain text format file including a plurality of attributes;

using the attributes to identify data having an identified classification level from a collection of data including both data having the identified classification level and data having a higher classification level; and

extracting the data having the identified classification level from the collection of data.
