Online social networks provide attractive platform to sharing information for users. In recent years, exponentially increasing the number of online social networks users and being accessible considerable volume of information caused some concerns in term of user privacy in these networks. This mass volume of information increases motivation of intruders to try to accessing them. It seems important and necessary to providing some mechanisms to prevent disclosing private information and valuable data lying in these networks. In recent years, many research tried to provide security approaches and architecture to protecting privacy. Most of these researches were focused on protecting user data against external factors and social network members. In this work, we propose a solution to protect user private data against service provider that maintains functional capabilities of current social networks. This solution is provided in the form of decentralized architecture that leveling user data. Proposed solution enables private data sharing for users and public data sharing for service providers to support attractive capabilities of current social networks by defining a new decentralized architecture for them. This architecture implemented by utilizes Onion routing based on tour network hidden service for data transmission and obtained results compared with some existing architectures.
