Abstract

Claims (35)

1. A computerized system for determining an intent of a sender in transmitting electronic information in order to prevent unauthorized dissemination of the electronic information and to facilitate cost-effective handling of dissemination events, the system comprising:

computer hardware configured by instructions to determine whether a distribution list of the electronic information includes both a plurality of authorized addresses and one or more unauthorized addresses,

and configured by instructions to determine whether the distribution list of the electronic information includes an unauthorized address whose edit distance from another authorized address is below a threshold,

and configured by instructions to determine whether the sender replies to an original message using a reply to all feature to transmit the electronic information, and an original sender of the original message is authorized,

and configured to execute an intention assessment unit to determine if the intent in sending the electronic information is malicious or a mistake, wherein the sender's intent is determined to be a mistake if:

a distribution list of the electronic information includes both a plurality of authorized addresses and one or more unauthorized addresses, or

the distribution list of the electronic information includes an unauthorized address whose edit distance from another authorized address is below a threshold, or

the sender replies to an original message using a reply to all feature to transmit the electronic information, and an original sender of the original message is authorized.

2. The system of claim 1 , wherein the electronic information comprises descriptors, and wherein the descriptors comprise at least one of the content of the message, the sender of the message, and a recipient of the message.

3. The system of claim 1 , wherein the intention assessment unit is configured to determine whether the electronic information should be disseminated.

4. The system of claim 1 , wherein the intention assessment unit is configured to determine whether the decision about dissemination of the information should be made by the sender.

5. The system of claim 4 , wherein the intention assessment unit evaluates a confidence level based on previously defined confidential information and a severity based at least in part on the potential damage if the electronic information is disseminated.

6. The system of claim 1 , wherein the electronic information comprises descriptors and parameters and wherein the intention assessment unit compares the descriptors and parameters of the electronic information to predefined scenarios in order to determine whether the electronic information should be disseminated.

7. The system of claim 6 , wherein the predefined scenarios are generated from previous electronic information dissemination events.

8. A computer-implemented method for determining an intent of a sender in transmitting electronic information in order to prevent unauthorized dissemination of the electronic information, the method comprising:

receiving the electronic information from a computer network;

determining descriptors and parameters of the electronic information, wherein the descriptors and parameters include a message distribution list;

determining a first condition, based on the descriptors and parameters, of whether the message distribution list includes both a plurality of authorized addresses and one or more unauthorized addresses;

determining a second condition, based on the descriptors and parameters, of whether the distribution list of the electronic information includes an unauthorized address whose edit distance from another, authorized address is below a threshold, or

determining a third condition, based on the descriptors and parameters, of whether the sender replies to an original message using a reply to all feature to transmit the electronic information, and an original sender of the original message is authorized; and

determining the sender mistakenly transmitted the electronic information if at least one of the first condition, second condition, and third condition are true;

sending a network message to the sender if the sender mistakenly transmitted the electronic information.

9. The method of claim 8 , further comprising determining whether the intent of the sender is malicious.

10. The method of claim 8 , further comprising:

determining a confidence level based on a level of similarity of the electronic information to previously defined confidential information;

determining a severity based at least in part on the potential damage if the electronic information is disseminated; and

determining the intent of the sender based, at least in part, on the severity and the confidence level.

11. The method of claim 10 , further comprising determining whether the electronic information should be quarantined based, at least in part, on the determined intent of the sender.

12. The method of claim 11 , further comprising determining whether the decision about releasing the electronic information from the quarantine should be made by the sender based, at least in part, on the determined intent of the sender.

13. The method of claim 8 , further comprising comparing the descriptors and parameters of the electronic information to predefined scenarios in order to determine the intent of the sender.

14. The method of claim 13 , wherein comparing the descriptors and parameters of the electronic information to predefined scenarios comprises finding a nearest neighbor between the descriptors and parameters and the predefined scenarios.

15. The method of claim 8 , further comprising applying heuristics based on the email addresses of the sender and one or more recipients in the distribution list to assess the intention of the sender.

16. The method of claim 8 , further comprising determining whether the electronic information should be disseminated based, at least in part, on the determined intent of the sender.

17. The method of claim 8 , further comprising using the determined intent of the sender in determining whether the decision about dissemination of the information should be made by the sender.

18. The method of claim 11 , further comprising informing the sender of the actions required to release the message from quarantine.
