최근 빠르게 확산되고 있는 온라인 소셜 네트워크 서비스는 수많은 데이터를 저장하고 이를 분석하여 여러 연구 분야에 활용하고 있다. 정보의 효율성을 높이기 위해 기업이나 공공기관은 자신들이 가진 데이터를 배포하고, 배포된 데이터를 이용하여 여러 목적에 사용한다. 그러나 배포되는 소셜 네트워크에는 개인과 관련된 정보가 포함되어 있으므로 개인 프라이버시가 노출될 수 있는 문제가 있다. 배포되는 소셜 네트워크에서 단순히 이름 등의 식별자를 지우는 것으로는 개인 프라이버시 보호에 충분하지 않으며, 소셜 네트워크가 가진 구조적 정보에 의해서도 개인 프라이버시가 노출될 수 있다. 본 논문에서는 내용 정보를 포함하고 있는 소셜 네트워크 배포 시 개인 프라이버시 노출에 이용되는 복합된 공격법을 제시하고 이를 방지할 수 있는 새로운 모델인 $\ell$-차수 다양성($\ell$-degree diversity)을 제안한다. $\ell$-차수 다양성은 소셜 네트워크 데이터 배포에서 $\ell$-다양성을 최초로 적용한 모델이며 높은 정보 보존율을 가짐을 실험을 통해 볼 수 있다.

소셜 사물 인터넷(SIoT)에서 차량들이 다양한 정보를 생성하고 이를 다른 차량과 공유하고 피드백을 주고 받는 소셜 행위가 이루어진다. 차량 간에 신뢰성 있는 정보를 공유하기 위해서는 차량의 신뢰성을 판별하는 것이 중요하다. 본 논문에서는 차량들 간에 신뢰성 있는 정보를 공유하기 위한 차량 신뢰도 계산 기법을 제안한다. 제안하는 기법은 차량 간 소셜 행위에 기반한 사용자 평판과 네트워크 신뢰도를 고려하여 차량 신뢰도를 판별한다. 차량은 점수 부여, 무시, 재배포 등의 행위를 선택할 수 있으며 이에 따라 사용자 평판이 계산된다. 네트워크 신뢰도를 계산하기 위해 다른 차량과의 거리와 패킷 전송률을 이용한다. 사용자 평판과 네트워크 신뢰도를 이용하여 지역 신뢰도가 계산된다. 이때, 전달되는 데이터의 중복 배포를 방지한다. RSU(Road Side Unit)의 데이터를 활용하여 지역적인 데이터의 한계를 극복하고 전역적인 데이터를 활용하여 보다 더 정확한 차량 신뢰도 계산이 가능하다. 다양한 성능평가를 통해 제안하는 기법이 기존 기법에 비해서 성능이 우수함을 보인다.
