IoT MEMORY-EFFICIENT VIRTUAL EMAIL ADDRESS CREATING AND TRACKING METHOD TO PREVENT PERSONAL INFORMATION LEAKAGE IN IOT ENVIRONMENT

摘要

The present invention relates to a memory efficient virtual email address generation and tracking method for preventing personal information leakage in an IoT environment, and more particularly, to a method and apparatus for generating and tracking e-mail that is performed in a user device, a personal information management server, and an email proxy server (1) receiving an encryption key generation request from a user device in the personal information management server; (2) generating an encryption key according to the request of step (1) in the personal information management server, and generating a decryption key for decrypting the encryption key; (3) generating an encrypted virtual email address for the email address of the address book stored in the user device, using the encryption key generated in step (2) in the user device; (4) the encryption key generated in the step (2) is transmitted to the user device in the personal information management server, and the decryption key is transmitted to the e-mail proxy server; (5) If the virtual e-mail address generated in step (3) is leaked and the e-mail proxy server receives a spam mail with a virtual e-mail address of a third party, the e-mail proxy server uses the decryption key The virtual email address is decrypted to track the service or application that accessed the virtual email address of the third party; And (6) a guide mail including information on the service or application tracked in the step (5) in the e-mail proxy server is transmitted in the e-mail of the user. The present invention also relates to a memory efficient virtual email address generation and tracking method for preventing personal information leakage in an IoT environment. More specifically, the present invention relates to a method and apparatus for generating and tracking e-mail that is performed in a user device, a personal information management server, The method includes the steps of: (1) receiving an encryption key generation request from a user device in the personal information management server; (2) generating an encryption key according to the request of step (1) in the personal information management server, and generating a decryption key for decrypting the encryption key; (3) generating an encrypted virtual email address for the email address of the address book stored in the user device, using the encryption key generated in step (2) in the user device; (4) the encryption key generated in the step (2) is transmitted to the user device in the personal information management server, and the decryption key is transmitted to the e-mail proxy server; (5) If the virtual e-mail address generated in step (3) is leaked and the e-mail proxy server receives a spam mail with a virtual e-mail address of a third party, the e-mail proxy server uses the decryption key The virtual email address is decrypted to track the service or application that accessed the virtual email address of the third party; And (6) a guide mail including information on the service or application tracked in the step (5) in the e-mail proxy server is transmitted in a third party's e-mail. According to the memory efficient virtual email address generation and tracking method for preventing personal information leakage in the IoT environment proposed in the present invention, a virtual email address is generated for each service or application requesting an email address, You can track which services or applications have been compromised, and block spilled virtual email addresses to stop receiving spam. In addition, according to the present invention, only an encryption / decryption key capable of encrypting and decrypting an e-mail address can be stored, while maintaining the effect of generating and tracking virtual e-mails, And the size of the data to be stored and managed is very small, so that the size of the database can be reduced.
