There is a great interest in many approaches towards blockchain in providinga solution to record transactions in a decentralized way. However, there aresome limitations when storing large files or documents on the blockchain. Inorder to meet the requirements of storing relatively large data, adecentralized storage medium is produced. IPFS is a distributed file systemwhich is content-addressable. It works very similar to the blockchain network.There are some attempts which take advantage of the blockchain concept and IPFSto design new approaches. Unfortunately, there are some inefficiencies insharing data using the combination of IPFS and blockchain. In this paper, weproposed a secure file sharing system that brings a distributed access controland group key management by the adoption of the IPFS proxy. The IPFS proxywhich plays an important role in the design is adopted to take responsibilityfor the control policies. The combination of the IPFS server and the blockchainnetwork with the adoption of the IPFS proxy make a secure file sharing systemwhich the members on the system can create new groups or join different groupsby their own choice. Although there is no access control mechanism in IPFSserver and blockchain network, the secure file sharing system manages theaccess control policies. The members access files only belong to the group theyauthorized.
