Tagging is most widely used feature in online networks. There are no of tags are available mainly offline resources based on their feedback, expressed in the form of free-text labels (i.e., tags). Recently there is a problem based on the tagging of feedback, free-text labels etc. Without user permission tags are automatically generated spam scripts. So, users are facing many sensitive problems like privacy. In the existing system, a privacy-preserving collaborative tagging service, by showing how a specific privacy-enhancing technology, namely tag suppression, can be used to protect end-user privacy. Some problems identified in the existing system. To overcome these problems captcha based security in introduced in the proposed system to provide better security for the tagging information. Results will show the performance of the proposed system.
