Abstract

A method, system and computer-usable medium are disclosed for generating a cyber behavior profile, comprising: monitoring user interactions between a user and an information handling system; converting the user interactions and the information about the user into electronic information representing the user interactions; generating a unique cyber behavior profile based upon the electronic information representing the user interactions and the information about the user; and, storing information relating to the unique cyber behavior profile in a behavior blockchain.

Claims

1. A computer-implementable method for generating a cyber behavior profile, comprising:

monitoring electronically-observable user behavior;

converting the electronically-observable user behavior into electronic information representing the electronically-observable user behavior, the electronic information representing the electronically-observable user behavior comprising respective user behavior elements;

generating a user behavior profile based upon the electronic information representing the electronically-observable user behavior;

storing the respective user behavior elements in user behavior blocks of behavior profile in a behavior blockchain;

determining whether a user behavior element is suspect;

generating a user behavior block using the user behavior element; and

,

appending the user behavior block to the behavior blockchain, the user behavior block comprising a known good user behavior element when the user behavior element is not suspect and a suspect user behavior element when the user behavior element is suspect.

2. The method of claim 1, wherein:

the user behavior profile is based upon at least one of an identification factor and a user behavior factor.

3. The method of claim 1, wherein:

the user behavior block comprises a transaction payload; and

,

the transaction payload includes a representation of the user behavior profile.

4. The method of claim 3, wherein:

the transaction payload comprises executable code, the executable code being used by a user behavior monitoring system to detect at least one of acceptable behavior, anomalous behavior, malicious behavior and unknown behavior being enacted by a user.

5. The method of claim 3, wherein:

the transaction payload comprises a user behavior score, the user behavior score being used by a user behavior monitoring system to assess a particular user while enacting a given user behavior.

6. A system comprising:

a processor;

a data bus coupled to the processor; and

a non-transitory, computer-readable storage medium embodying computer program code, the non-transitory, computer-readable storage medium being coupled to the data bus, the computer program code interacting with a plurality of computer operations and comprising instructions executable by the processor and configured for;

monitoring electronically-observable user behavior;

converting the electronically-observable user behavior into electronic information representing the electronically-observable user behavior, the electronic information representing the electronically-observable user behavior comprising respective user behavior elements;

generating a user behavior profile based upon the electronic information representing the electronically-observable user behavior;

storing the respective user behavior elements in user behavior blocks of behavior profile in a behavior blockchain;

determining whether a user behavior element is suspect;

generating a user behavior block using the user behavior element; and

,

appending the user behavior block to the behavior blockchain, the user behavior block comprising a known good user behavior element when the user behavior element is not suspect and a suspect user behavior element when the user behavior element is suspect.

7. The system of claim 6, wherein:

the user behavior profile is based upon at least one of an identification factor and a user behavior factor.

8. The system of claim 6, wherein:

the user behavior block comprises a transaction payload; and

,

the transaction payload includes a representation of the user behavior profile.

9. The system of claim 8, wherein:

the transaction payload comprises executable code, the executable code being used by a user behavior monitoring system to detect at least one of acceptable behavior, anomalous behavior, malicious behavior and unknown behavior being enacted by a user.

10. The system of claim 8, wherein:

the transaction payload comprises a user behavior score, the user behavior score being used by a user behavior monitoring system to assess a particular user while enacting a given user behavior.

11. A non-transitory, computer-readable storage medium embodying computer program code, the computer program code comprising computer executable instructions configured for:

monitoring electronically-observable user behavior;

converting the electronically-observable user behavior into electronic information representing the electronically-observable user behavior, the electronic information representing the electronically-observable user behavior comprising respective user behavior elements;

generating a user behavior profile based upon the electronic information representing the electronically-observable user behavior;

storing the respective user behavior elements in user behavior blocks of behavior profile in a behavior blockchain;

determining whether a user behavior element is suspect;

generating a user behavior block using the user behavior element; and

,

appending the user behavior block to the behavior blockchain, the user behavior block comprising a known good user behavior element when the user behavior element is not suspect and a suspect user behavior element when the user behavior element is suspect.

12. The non-transitory, computer-readable storage medium of claim 11, wherein:

the user behavior profile is based upon at least one of an identification factor and a user behavior factor.

13. The non-transitory, computer-readable storage medium of claim 11, wherein:

the user behavior block comprises a transaction payload; and

,

the transaction payload includes a representation of the user behavior profile.

14. The non-transitory, computer-readable storage medium of claim 13, wherein:

the transaction payload comprises executable code, the executable code being used by a user behavior monitoring system to detect at least one of acceptable behavior, anomalous behavior, malicious behavior and unknown behavior being enacted by a user.

15. The non-transitory, computer-readable storage medium of claim 13, wherein:

the transaction payload comprises a user behavior score, the user behavior score being used by a user behavior monitoring system to assess a particular user while enacting a given user behavior.

16. The non-transitory, computer-readable storage medium of claim 11, wherein the computer executable instructions are deployable to a client system from a server system at a remote location.

17. The non-transitory, computer-readable storage medium of claim 11, wherein the computer executable instructions are provided by a service provider to a user on an on-demand basis.
