My decision and my privacy networks

ABSTARCT :

In today’s world, most of the people utilize Online Social Networks (OSN) to mingle with people of their interest. Various new and innovative photo sharing features attract many users and kindle them to post several photos. The user has the privilege of posting any photo on his/her profile and share it with a range of people. Unfortunately, it may leak user’s privacy if others are allowed to post, comment, and tag a photo freely. To address this issue we have proposed a system that would notify OSN users, if any of their friends post a content that involves them. The Face Recognition (FR) system extracts facial features of the user’s friends and gets trained. If the user’s friend posts a photo that includes people other than himself/herself, then that photo is fed into FR system. The system detects all faces in the photo, locates facial details and compares with the faces of the other friends in the list.

EXISTING SYSTEM :

? It allows users to easily choose suites of privacy settings that can be created by an expert using privacy programming or can be created through exporting them to the abstract format or through existing configuration UIs. ? A Privacy suite can be verified by a good practice, a high level language and motivated users which then can be then distributed to the members of the social sites through existing distribution channels. ? It presents a system that consists of policies in the form of constraints on the type, depth and the trust level of the relationship that are existing on the access control model for Web-based social networks (WBSNs).

DISADVANTAGE :

? There's no restriction with sharing of co-photos. On the contrary, social network service suppliers like Facebook are encouraging users to post co-photos and tag their friends so as to attract a lot of folks. ? Unfortunately, on most current OSNs, users do not have any management over the details leaked outside their profile page. ? People are unaware of their photos being posted on their friend’s profile. ? This creates an issue for users who share media without knowledge of this occurring. The exploitation of a single shared photo can result in an adversary.

PROPOSED SYSTEM :

• While intensive research interests lie in FR engines refined by social connections, the security and privacy issues in OSNs also emerge as important and crucial research topics. • Orthogonal to the traditional cryptographic solution, this work proposes a consensus-based method to achieve privacy and efficiency. • Basically, in our proposed one-against-one strategy a user needs to establish classifiers between self, friend and friend, friend also known as the two loops in Algorithm. • To break this dilemma, we propose a privacy-preserving distributed collaborative training system as our FR engine. In our system, we ask each of our users to establish a private photo set of their own.

ADVANTAGE :

? We propose a privacy-preserving, distributed and collaborative training system. In our system, we ask each of our users to establish a private photo set of their own, ensuring to make use of it only for the FR system. ? We use these private photos to build personal Face Recognition engine based on the specific facial context. ? We have proposed a novel consensus based approach that would efficiently deal with the privacy of the users. ? All the faces in the photograph are recognised. Each person’s facial specifications are verified with the FR system, which has student the facial specifications of the user’s friends. ? User’s friends on the photo are identified and a request notification is sent to their profile for them to decide on uploading the photo.
