Sensitive Label Privacy Protection on Social Network Data

                   Sensitive Label Privacy Protection on Social

                                         Network Data

ABSTRACT

                         This project is motivated by the recognition of the need for a finer grain and more personalized privacy in data publication of social networks. We propose a privacy protection scheme that not only prevents the disclosure of identity of users but also the disclosure of selected features in users' profiles. An individual user can select which features of her profiles she wishes to conceal. The social networks are modeled as graphs in which users are nodes and features are labels. Labels are denoted either as sensitive or as non-sensitive. We treat node labels both as background knowledge an adversary may possess, and as sensitive

information that has to be protected. We present privacy protection algorithms

that allow for graph data to be published in a form such that an adversary who possesses information about a node's neighborhood cannot safely infer its identity and its sensitive labels. To this aim, the algorithms transform the original graph into a graph in which nodes are sufficiently indistinguishable. The algorithms are designed to do so while losing as little information and while preserving as much utility as possible. We evaluate empirically the extent to which the algorithms

preserve the original graph's structure and properties. We show that our solution is effective, efficient and scalable while offering stronger privacy guarantees than those in previous research.

                                          

 Existing System

                       

                       The current trend in the Social Network it not giving the privacy about user profile views. The method of data sharing or (Posting) has taking more time and not under the certain condition of displaying sensitive and non-sensitive data.

Problems on existing system:

1.     There is no way to publish the Non sensitive data to all in social Network.

2.     It’s not providing privacy about user profiles.

3.     Some mechanisms that prevent both inadvertent private information leakage and attacks by malicious adversaries.

Proposed System

            Here, we extend the existing definitions of modules and we introduced the sensitive or non-sensitive label concept in our project. We overcome the existing system disadvantages in our project.

Advantages:

1.     We can publish the Non sensitive data to every-one in social Network.

2.     It’s providing privacy for the user profiles so that unwanted persons not able to view your profiles.

3.     We can post sensitive data to particular peoples and same way we can post non-sensitive data to everyone like ads or job posts.

                                  IMPLEMENTATION

             Implementation is the stage of the project when the theoretical design is turned out into a working system. Thus it can be considered to be the most critical stage in achieving a successful new system and in giving the user, confidence that the new system will work and be effective.

               The implementation stage involves careful planning, investigation of the existing system and it’s constraints on implementation, designing of methods to achieve changeover and evaluation of changeover methods.

Main Modules:-

1.    User Module:

                 In this module, Users are having authentication and security to access the detail which is presented in the ontology system. Before accessing or searching the details user should have the account in that otherwise they should register first.

.

2.Information Loss:

            We aim to keep information loss low. In- formation loss in this case contains both structure information loss and label information loss. There are  some  non sensitive  data’s  are Loss due to Privacy making so we can’t send out full information to the public.

3. Sensitive Label Privacy Protection:

                There are who post the image to the online social network if allow the people for showing the image it will display to his requesters it make as the sensitive  to that user. Ths is is very useful to make sensitive data for the public .
