Abstract

Systems for instant messaging private tags preferably comprise a parser for parsing an instant message for sensitive data and an encryption engine for encrypting the sensitive data. A modified uuencoder is also preferably included for converting the encrypted sensitive data into a data stream that complies with an XML format. Other systems and methods are also provided.

Claims

1. A method comprising:

transmitting a first data stream, the transmitting comprising;

parsing unstructured text content within a first message to identify, from the text content, a first set of sensitive data;

encrypting the first set of sensitive data using an encryption type identified by a first name and value pair;

transmitting the first message in the first data stream with a first set of private tags surrounding the first set of sensitive data, the first set of private tags identifying the first name and value pair;

receiving a second data stream, the receiving comprising;

parsing the second data stream to identify a second set of private tags surrounding a second set of sensitive data in a second message; and

decrypting the second set of sensitive data using a decryption type identified by a second name and value pair identified by the second set of private tags.

2. The method of claim 1, further comprising:

removing the second set of private tags surrounding the second set of sensitive data in the second message to generate an original second message.

3. The method of claim 2, further comprising:

transmitting the original second message to a recipient.

4. The method of claim 1, further comprising:

converting the first data stream into an extensible markup language compliant format.

5. The method of claim 1, wherein the parsing the first message comprises:

identifying the first set of sensitive data by evaluating the text content using user defined rules.

6. The method of claim 1, wherein the parsing the first message comprises:

identifying the first set of sensitive data using identifiers entered by a user and forming part of the text content in the first message.

7. The method of claim 1, wherein the sensitive data comprises one of bank account information, credit card information, and social security information.

8. An apparatus comprising:

a processor; and

a memory to store computer program instructions, the computer program instructions when executed on the processor cause the processor to perform operations comprising;

transmitting a first data stream, the transmitting comprising;

parsing unstructured text content within a first message to identify, from the text content, a first set of sensitive data;

encrypting the first set of sensitive data using an encryption type identified by a first name and value pair;

transmitting the first message in the first data stream with a first set of private tags surrounding the first set of sensitive data, the first set of private tags identifying the first name and value pair;

receiving a second data stream, the receiving comprising;

parsing the second data stream to identify a second set of private tags surrounding a second set of sensitive data in a second message; and

decrypting the second set of sensitive data using a decryption type identified by a second name and value pair identified by the second set of private tags.

9. The apparatus of claim 8, the operations further comprising:

removing the second set of private tags surrounding the second set of sensitive data in the second message to generate an original second message.

10. The apparatus of claim 9, the operations further comprising:

transmitting the original second message to a recipient.

11. The apparatus of claim 8, the operations further comprising:

converting the first data stream into an extensible markup language compliant format.

12. The apparatus of claim 8, wherein the parsing the first message comprises:

identifying the first set of sensitive data by evaluating the text content using user defined rules.

13. The apparatus of claim 8, wherein the parsing the first message comprises:

identifying the first set of sensitive data using identifiers entered by a user and forming part of the text content in the first message.

14. The apparatus of claim 8, wherein the sensitive data comprises one of bank account information, credit card information, and social security information.

15. A non-transitory computer readable medium storing computer program instructions, which, when executed on a processor, cause the processor to perform operations comprising:

transmitting a first data stream, the transmitting comprising;

parsing unstructured text content within a first message to identify, from the text content, a first set of sensitive data;

encrypting the first set of sensitive data using an encryption type identified by a first name and value pair;

transmitting the first message in the first data stream with a first set of private tags surrounding the first set of sensitive data, the first set of private tags identifying the first name and value pair;

receiving a second data stream, the receiving comprising;

parsing the second data stream to identify a second set of private tags surrounding a second set of sensitive data in a second message; and

decrypting the second set of sensitive data using a decryption type identified by a second name and value pair identified by the second set of private tags.

16. The computer readable medium of claim 15, the operation further comprising:

removing the second set of private tags surrounding the second set of sensitive data in the second message to generate an original second message.

17. The computer readable medium of claim 16, the operations further comprising:

transmitting the original second message to a recipient.

18. The computer readable medium of claim 15, the operations further comprising:

converting the first data stream into an extensible markup language compliant format.

19. The computer readable medium of claim 15, wherein the parsing the first message comprises:

identifying the first set of sensitive data by evaluating the text content using user defined rules.

20. The computer readable medium of claim 15, wherein the parsing the first message comprises:

identifying the first set of sensitive data using user entered identifiers entered by a user and forming part of the text content in the first message.
