System and method for detecting confidential information emails
Systems and methods are disclosed for detecting confidential information emails. In accordance with one implementation, a method is provided for detecting confidential information emails. The method includes obtaining a sender address of an electronic message, the sender address comprising a first username and a first domain name, and obtaining at least one recipient address of the electronic message, the recipient address comprising a second username and a second domain name. The method also includes determining whether the recipient address and the sender address are different addresses of a user, and based on the determination, flagging the electronic message.
1. An electronic device comprising:
one or more non-transitory computer-readable storage media configured to store instructions; and
one or more processors configured to execute the instructions stored on the one or more non-transitory computer-readable storage media to cause the electronic device to:
determine sender data from a message, the sender data comprising a first domain name of a sender address;
determine a recipient address from the message, the recipient address comprising a second domain name different from the first domain name;
finding a mismatch between the first domain name of the sender address and the second domain name of the recipient address;
finding a relationship between another part of the recipient address and at least a portion of the sender data;
determine that the recipient address and the sender address are related to a same user based on the mismatch and the relationship;
determine that the message comprises confidential content; and
flag the message based at least in part on the determination that the recipient address and the sender address are related to a same user.
2. The electronic device of claim 1 , wherein the sender data comprises a first username.
3. The electronic device of claim 1 , wherein the relationship between the another part of the recipient address and the at least a portion of the sender data comprises matching at least data portions of the recipient address with the sender address, the first name of the sender, or the last name of the sender.
4. The electronic device of claim 1 , wherein the first domain name is associated with a particular business and the second domain name is associated with an entity that provides electronic communication accounts to consumers.
5. The electronic device of claim 1 , wherein the first domain name is associated with an entity that provides electronic communication accounts to consumers and the second domain name is associated with a particular business.
6. The electronic device of claim 1 , further comprising:
determine a probability that the message is unauthorized, wherein said flagging the message is based on the determined probability.
7. The electronic device of claim 1 , wherein the another part of the recipient address is the second domain name and the at least a portion of the sender data is a surname of the sender included in the sender address.
8. A computerized method, performed by one or more processors configured to execute instructions stored on a non-transitory computer-readable storage media, comprising:
determining sender data from a message, the sender data comprising a first domain name of a sender address;
determining a recipient address from the message, the recipient address comprising a second domain name different from the first domain name;
finding a mismatch between the first domain name of the sender address and the second domain name of the recipient address;
finding a relationship between another part of the recipient address and at least a portion of the sender data;
determining that the recipient address and the sender address are related to a same user based on the mismatch and the relationship; and
flagging the message based at least in part on the determination that the recipient address and the sender address are related to a same user.
9. The method of claim 8 , wherein the sender data comprises a first username.
10. The method of claim 8 , wherein the relationship between the another part of the recipient address and the at least a portion of the sender data comprises matching at least data portions of the recipient address with the sender address, the first name of the sender, or the last name of the sender.
11. The method of claim 8 , wherein the first domain name is associated with a particular business and the second domain name is associated with an entity that provides electronic communication accounts to consumers.
12. The method of claim 8 , wherein the first domain name is associated with an entity that provides electronic communication accounts to consumers and the second domain name is associated with a particular business.
13. The method of claim 8 , further comprising:
determine a probability that the message is unauthorized, wherein said flagging the message is based on the determined probability.
14. The method of claim 8 , wherein the another part of the recipient address is the second domain name and the at least a portion of the sender data is a surname of the sender included in the sender address.
