Review of Privacy Violation Identification Methods for Social Networking Sites

An individual or group can seclude themselves by the ability of privacy , or information about themselves or related to them, and thereby express themselves selectively. ―The boundaries and content that is considered private differ among cultures and individuals, but share common themes or platform. When something is private or exclusive to a person, it commonly means that something is personal or inherently special and sensitive to them. The domain of privacy partially overlaps security (confidentiality), and it includes concepts of appropriate use, and protection of information as well [1].‖ Violation of Privacy or intrusion in private data by misusing someone‘s private information, like their passwords or passkeys, their security numbers or codes, can steal privacy for a user, which is illegal as invasion of privacy [2].

1. Private user information enters the program. 2. The data is written to the external locations, for instance the console, file system, network, etc. Private data can enter a program in the various ways: 1. Directly from the user in the form of a password or personal information 2. Accessed from a database or other data store by the application 3. Indirectly from a partner or other third party There are 2 important axis to understand the privacy violations: 1. One is the main contributor of the situation 2. The other axis tells about how information or data is disclosed or revealed‖ 1.1. Threats of Online Social Networks Social networking sites are the platform at which any user is allowed to share data that access other users to read, saw and interact with[3]. This can be the user themselves sharing an information that may lead to or canreveal private data or it can be some other user that are sharing content that reveals the data about some other user that they are not comfortable to show. A much better approach for managing users‘privacy is for detecting privacy violations and make the user aware of it so that they can secure the content as per their need. It‘s crucial that if privacy of an user is violated, then the system takes an appropriate and immediate action to avoid this or if that cannot be done then letting the user be aware of the circumstance so that they can fix it. In today‘s world, users are expected to take note of their privacy and take care of it by 1.2. Social Network Site Review Detecting privacy violations are done in a very centralized manner [4]. First implementation are needed for privacy agreements between agents. Second, to develop model further to identify privacy violations itself before they can arise in this system. It helps agents to reach problems automatically improving the system further. Agents may have privacy issues and these conflicts should be secured as their privacy is utmost. The next step is that researchers uses technologies to shield privacy; example, making of an offer or a counter-offer to negotiate; making of an argument and an attack in argumentation. The analytical structure of an SNS is shown in Figure 1.

Figure 1: Analytical Structure of an SNS It has found that solving some of this conflicting situations are very useful. This information is enough to be processed further by agent, then the agent will make the decision whether a post is private or not. Therefore, user can take action themselves, and it has never been used before in the context of privacy and since users itself sometimes don‘t have faith in a central to protect their privacy. Maybe it may need asking for proofs from other sources and agents as well and new ways are found for agents so they can gather such proofs to detect violation of privacy.

To review these techniques there are three ways. 1. To abstract the commitment among individuals when carrying out agreements. 2. Checking and verifying that characteristic properties hold in the system or not. 3. Using the help of ontologies to define semantics of concepts related to OSNs and privacy and reason about their relationships.

A commitment (if a specified condition is achieved) is a deal between two people about to bring about a specific attribute [5]. A commitment is not simply a agreement. To achieve this, a commitment is associated with a state of the system that develops over time in coordination with the state of the representation agreement. In the conditional state, a commitment is made, in which neither the response nor the commitment results successfully. When the commitment response is received, the commitment status changes to Active. If the result of the commitment is satisfied, the commitment condition changes to the state of completion.

Zhou et al. [6] show that by processing public information about social network users, one can identify various personal traits such as whether the person is aloof or not.Golbeck and Hanson [7] showed the way of seeing how we can spot political choices of different users on a social networking, truly based on what these users allows us to see. Heatherly et al. [10] use inference attacks using social networking data is to predict private information and propose sanitization techniques to prevent inference attacks made by attacker . All these efforts helps one to find and know about user‘s personal info with their own consent. 3.1. Ontology Ontology is an understanding for a specific domain. It aids in stating concepts of domain and their relations semantically. We can describe these concepts by using their attributes. The connections permit concepts to hold together. A usual connection between concepts is the relation, which tells that one concept. From the perspective of privacy, that content linked to privacy can be seen as a domain system and shown as an ontology technique.That the information given or represented was not given by the user. The second set helps to recognize risky user‘s who are highly likely to violate privacy of anyone. While it is a very informative that when initial information is not therein the system, would not be an approachable way to work.

Current system for privacy violation available on social networking sites is similar to the violations of access control. In access control scenarios, there is only one authority can permit access to users when they requires. Though , in social networking sites, there are numerous sources to control, i. e. Every user can give their contribution in sharing of the content by putting up posts and pictures of them or others. Furthermore, viewers of a post can re-share the content, makes it accessible to watch or interact for others. Though these interactions can sometimes leads to privacy violation, having access to their posts.

5. REVIEW OUTCOME

After performing many surveys, it has become very clear that all around the world users are facing privacy violations and related concerns in their everyday life. Each and every work is done and handled easily by the first violation type as it is endogenous and direct. This is, this privacy constraint can be enforced if a user can tell that a privacy constraint is not related to any other or someone else‘s user‘s perspective.

In this paper we discussed about many different privacy related queries and issues and saw the approach to solve them. It includes privacy content, relationship between a user and the other content types, is collected with the help of using description logic to explain the social network domain and commitments that helps a user or helps the system to clear the privacy requirement of the user‘s itself.
