| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have proposed a location-based forwarding scheme for Named Data Networking, in which consumers retrieve content from geographically distributed IoT devices by sending requests specifying the locations of their interests. However, this content retrieval scheme has a drawback that the locations of consumers' interests are revealed to adversaries on the networks because the names of the locations are carried in the content requests in plaintext. This allows the adversaries to obtain sensitive information of the consumers, such as their addresses and life styles. In this paper, we propose a $k$-anonymity based scheme to preserve consumers' privacy. More specifically, in our scheme, consumers issue requests to a set of $k$ locations at the same time to hide their locations of interests in a crowd of $k$ locations. In addition, to prevent adversaries from inferring the locations of interests from the identities of consumers, those requests are forwarded through a relay node called an anonymizer. | |
