ارائه روشی مبتنی بر بلاکچین برای حفظ حریم خصوصی کاربران در شبکه‌های اجتماعی

چکیده مقاله :

امروزه شبکه‌های اجتماعی راحتی زیادی را برای کاربران خود به ارمغان آورده‌اند، اما هنوز مشکلات عدم رعایت حریم خصوصی وجود دارد. همین امر باعث شده امنیت و حفاظت از حریم خصوصی کاربران شبکه‌های اجتماعی مورد اهمیت قرار بگیرد. کاربران مقدار زیادی از داده‌های شخصی در شبکه‌های اجتماعی به اشتراک می‌گذارند، مهاجمان می‌توانند اطلاعات شخصی حساس را به سادگی با استفاده از شبکه‌های اجتماعی به دست آورند و انواع مختلفی از حملات و سرقت هویت را انجام دهند. بسیاری از شبکه‌های اجتماعی مراکز داده خود را ندارند و معمولاً داده‌های کاربر را در مراکز داده شخص ثالث ذخیره می‌کنند. این مراکز می‌توانند این داده‌ها را با سایرین اشتراک بگذارند و داده‌های کاربر را بدون اطلاع آن‌ها در اختیار سازمان‌های دیگر قرار دهند. مالکان شبکه‌های اجتماعی می‌توانند داده‌های کاربران را در اختیار آژانس‌های اطلاعاتی قرار دهند و یا از آنها در زمینه‌های تبلیغاتی استفاده کنند. در این تحقیق در بخش اول مقدمه موضوع را شرح داده‌ایم و پس از آن در بخش دوم به ادبیات موضوع پرداخته‌ایم که بیشتر تمرکز کارهای قبلی بروی روش‌های متمرکز حفظ حریم خصوصی می‌باشد و سپس در بخش سوم روش تحقیق را شرح داده‌ایم و روشی را ارائه داده‌ایم که با استفاده از بلاکچین حریم خصوصی کاربران در شبکه‌های اجتماعی تا حد زیادی افزایش پیدا می‌کند. در بخش چهارم اجرای تحقیق را شرح داده‌ایم و در نهایت به نتیجه‌گیری و جمع‌بندی از این تحقیق پرداخته‌ایم.

چکیده انگلیسی :

Today, social networks have brought a lot of convenience to their users, but there are still problems of not respecting privacy. This has caused the security and privacy protection of social network users to be important. Users share a large amount of personal data on social networks, attackers can obtain sensitive personal information simply by using social networks. and carry out various types of attacks and identity theft. Many social networks do not have their own data centers and usually store user data in third-party data centers. These centers can share this data with others and provide user data to other organizations without their knowledge. Owners of social networks can provide users' data to information agencies or use them for advertising purposes. In this research, in the first part, we have described the introduction of the subject, and then in the second part, we have discussed the literature on the subject, which is mostly focused on the centralized methods of privacy protection, and then in the third part, we have described the research method. And we have presented a method that increases the privacy of users in social networks to a great extent by using blockchain. In the fourth part, we have described the implementation of the research and finally we have concluded and summarized this research.
