Abstract

An exemplary system for detecting and preventing voice data leakage may comprise one or more servers running a packet payload converter module, a transcript generator module, and a detection logic module. The packet payload converter module may receive VoIP packets, convert them to a digital audio file, and write the digital audio file to a media database. The transcript generator module may read the digital audio file from the media database, convert it to a text file, and write the text file to a transcript database. The detection logic module may read the text file from the transcript database, parse it into a plurality of keywords, determine whether the plurality of keywords contain one or more target keyword, and, if so, transmit a report to an events database.

Claims

1. A system, comprising:

one or more server computers communicatively coupled to a network running;

A) a packet payload converter module configured to;

i) receive a plurality of VoIP packets;

ii) convert said plurality of VoIP packets to a digital audio file; and

iii) write said digital audio file to a media database running on said one or more server computers;

B) a transcript generator module configured to;

i) read said digital audio file from said media database;

ii) convert said digital audio file to a text file; and

iii) write said text file to a transcript database running on said one or more server computer; and

C) a detection logic module configured to;

i) read said text file from said transcript database;

ii) parse said text file into a plurality of keywords;

iii) determine whether said plurality of keywords contains one or more target keywords; and

iv) responsive to a determination that said plurality of keywords contains said one or more target keywords, transmit a report to an events database running on said one or more server computer.

2. The system of claim 1, wherein said plurality of VoIP packets represent a conversation.

3. The system of claim 2, wherein said plurality of VoIP packets comprise a plurality of real-time transport protocol packets.

4. The system of claim 2, wherein said packet payload converter module is configured to convert said plurality of VoIP packets to said digital audio file by:

a) extracting a plurality of digital audio data from said plurality of VoIP packets; and

b) converting said plurality of digital audio data to said digital audio file.

5. The system of claim 1, wherein said one or more target keywords are received from a system administrator.

6. The system of claim 5, wherein said one or more target keywords comprise a personally-identifiable information, a credit card number, a social security number, a bank account number, a customer information, a name, an address, a phone number, an organizational secret, a curse word, a trade secret, an illegal activity, an improper activity, a medical information, a financial, or an accounting information.

7. The system of claim 1, wherein said events database is accessible to a system administrator via an event display portal.

8. The system of claim 7, wherein said report comprises a source phone number, a destination phone number, an internet protocol address, a time, a keyword, said digital audio file, or said text file associated with said conversation.

9. The system of claim 2, further comprising:

D) a censored communication generation module configured to;

i) generate a censored plurality of VoIP packets that excludes one or more VoIP packets corresponding to said one or more target keywords; and

ii) transmit said censored plurality of VoIP packets to a recipient.

10. The system of claim 9, wherein said censored communication generation module is configured to generate said censored plurality of VoIP packets by:

a) identifying one or more VoIP packets corresponding to each of said one or more target keywords located in said text file; and

b) deleting said one or more VoIP packets corresponding to each of said one or more target keywords located in said text file from said censored plurality of VoIP packets.

11. The system of claim 10, wherein said censored communication generation module is configured to substituting one or more silent packets for said one or more VoIP packets corresponding to each of said one or more target keywords located in said text file.

12. A system, comprising:

one or more server computers communicatively coupled to a network configured to;

A) receive a plurality of VoIP packets;

B) convert said plurality of VoIP packets to a digital audio file;

C) convert said digital audio file to a text file;

D) parse said text file into a plurality of keywords;

E) determine whether said plurality of keywords contains one or more target keywords entered by a system administrator; and

F) responsive to a determination that said plurality of keywords contains said one or more target keywords;

i) generate a censored plurality of VoIP packets that excludes one or more VoIP packets corresponding to said one or more target keywords; and

ii) transmit said censored plurality of VoIP packets to a recipient.

13. The system of claim 12, wherein said plurality of VoIP packets represent a conversation.

14. The system of claim 13, wherein said plurality of VoIP packets comprise a plurality of real-time transport protocol packets.

15. The system of claim 13, wherein said one or more server computers is further configured to convert said plurality of VoIP packets to said digital audio file by:

i) extracting a plurality of digital audio data from said plurality of VoIP packets; and

ii) converting said plurality of digital audio data to a plurality said digital audio file.

16. The system of claim 15, wherein said one or more server computers is further configured to store said digital audio file in a media database running on said one of more server computers.

17. The system of claim 16, further comprising a transcript generator module running on said one or more server computers configured to read said digital audio file from said media database, convert said digital audio file to said text file, and store said text file in a transcript database running on said one or more server computers.

18. The system of claim 12, wherein said one or more target keywords are received from a system administrator.

19. The system of claim 18, wherein said one or more target keywords comprise a personally-identifiable information, a credit card number, a social security number, a bank account number, a customer information, a name, an address, a phone number, an organizational secret, a curse word, a trade secret, an illegal activity, an improper activity, a medical information, a financial, or an accounting information.

20. The system of claim 12, where said one or more server computers are further configured to:

transmit a report to an events database running on said one or more server computers.

21. The system of claim 20, wherein said report comprises a source phone number, a destination phone number, an internet protocol address, a time, a keyword, said digital audio file, or said text file associated with said conversation.
