Abstract

Claims (102)

1. A system for implementing multilayer security using multiple codebooks, comprising:

a computing device comprising at least a memory and a processor;

a plurality of programming instructions stored in the memory and operable on the processor, wherein the plurality of programming instructions, when operating on the processor, cause the computing device to:

receive a document for encoding, the document comprising a plurality of sections;

analyze the document to identify security levels required for each section;

select, for each section, an appropriate codebook from a plurality of codebooks, each codebook associated with a specific security clearance level;

encode each section using its selected codebook;

generate metadata for each encoded section, including an associated codebook identifier and security level;

combine the encoded sections and their metadata into a secure document structure;

receive a request from a user to access the secure document;

authenticate the user and determine their security clearance level;

for each section of the secure document:

compare the user's clearance level to the section's required security level;

if the user's clearance level is sufficient, decode the section using the associated codebook;

if the user's clearance level is insufficient, replace the section with a redaction marker;

present the decoded document to the user, with authorized sections decoded and unauthorized sections redacted; and

maintain an audit trail of all encoding, decoding, and access activities.

2. The system of claim 1 , wherein the plurality of programming instructions further cause the computing device to:

implement a dynamic reclassification process to change the security level of a section without re-encoding the entire document, comprising:

receiving a reclassification request for a specific section;

verifying the authority of the user making the request;

retrieving and decoding the original content of the section;

selecting a new codebook based on the new security level;

re-encoding the section using the new codebook;

updating the section's metadata with the new codebook identifier and security level; and

replacing the old, encoded section with the newly encoded section in the secure document structure.

3. The system of claim 1 , wherein the plurality of codebooks are arranged in a hierarchical structure mirroring security clearance levels, and wherein a user with a higher clearance level can access sections encoded with codebooks of their level and all lower levels.

4. The system of claim 1 , wherein the plurality of programming instructions further cause the computing device to:

implement an expiring access feature by:

associating an expiration parameter with each codebook;

including expiration information in the metadata of each encoded section; and

preventing decoding of a section if its associated codebook has expired, even if the user has sufficient clearance level.

5. The system of claim 1 , wherein authenticating the user comprises implementing a multi-factor authentication process that:

determines the highest security level in the requested document;

identifies required authentication factors based on this security level; and

prompts the user for additional authentication factors if necessary before granting access.

6. The system of claim 1 , wherein the plurality of programming instructions further cause the computing device to:

implement a watermarking feature that:

generates a unique, user-specific watermark for each document access session;

inserts the watermark into decoded content before displaying it to the user; and

logs the association between the watermark, user, document, and access time.

7. The system of claim 1 , wherein encoding each section comprises:

dividing the section into blocks of a predetermined size;

encoding each block using the selected codebook; and

storing the encoded blocks along with their position information in the secure document structure.

8. The system of claim 1 , wherein the plurality of programming instructions further cause the computing device to compress the encoded sections using a lossless compression algorithm before combining them into the secure document structure.

9. The system of claim 1 , wherein the plurality of programming instructions further cause the computing device to:

implement a version control system that:

maintains a history of changes to the document, including security level changes;

allows rollback to previous versions of the document or specific sections; and

tracks which users made which changes and when.

10. The system of claim 1 , wherein the audit trail comprises user identification, timestamp, document identifier, sections accessed, and actions performed for each interaction with the system.

11. A method for implementing multilayer security using multiple codebooks, comprising the steps of:

receiving a document for encoding, the document comprising a plurality of sections;

analyzing the document to identify security levels required for each section;

selecting, for each section, an appropriate codebook from a plurality of codebooks, each codebook associated with a specific security clearance level;

encoding each section using its selected codebook;

generating metadata for each encoded section, including an associated codebook identifier and security level;

combining the encoded sections and their metadata into a secure document structure;

receiving a request from a user to access the secure document;

authenticating the user and determine their security clearance level;

for each section of the secure document:

comparing the user's clearance level to the section's required security level;

if the user's clearance level is sufficient, decoding the section using the associated codebook;

if the user's clearance level is insufficient, replacing the section with a redaction marker;

presenting the decoded document to the user, with authorized sections decoded and unauthorized sections redacted; and

maintaining an audit trail of all encoding, decoding, and access activities.

12. The method of claim 11 , further comprising the steps of:

implementing a dynamic reclassification process to change the security level of a section without re-encoding the entire document, comprising:

receiving a reclassification request for a specific section;

verifying the authority of the user making the request;

retrieving and decoding the original content of the section;

selecting a new codebook based on the new security level;

re-encoding the section using the new codebook;

updating the section's metadata with the new codebook identifier and security level; and

replacing the old, encoded section with the newly encoded section in the secure document structure.

13. The method of claim 11 , wherein the plurality of codebooks are arranged in a hierarchical structure mirroring security clearance levels, and wherein a user with a higher clearance level can access sections encoded with codebooks of their level and all lower levels.

14. The method of claim 11 , further comprising the steps of:

implementing an expiring access feature by:

associating an expiration parameter with each codebook;

including expiration information in the metadata of each encoded section; and

preventing decoding of a section if its associated codebook has expired, even if the user has sufficient clearance level.

15. The method of claim 11 , wherein authenticating the user comprises implementing a multi-factor authentication process that:

determines the highest security level in the requested document;

identifies required authentication factors based on this security level; and

prompts the user for additional authentication factors if necessary before granting access.

16. The method of claim 11 , further comprising the steps of:

implementing a watermarking feature that:

generates a unique, user-specific watermark for each document access session;

inserts the watermark into decoded content before displaying it to the user; and

logs the association between the watermark, user, document, and access time.
