Privacy preserving pattern matching : implementation issues

Abstract

The growing of the Internet has the potential to erode personal privacies. One can monitor a private data through the Internet without data owner knowledge. The project is to implement technique that allow pattern matching on user data and still preserve user privacy. Such technique gives possibility to place data on insecure third party site and be able to perform matching without revealing information about either data or pattern. The system uses public key cryptography to protect data on third part insecure site and to control revealing of data. The data owner participate in data decryption together with permitted data user.
