In　recent　years,　blockchain　has　emerged　as　a　new　decentralized　infrastructure　and　distributed　computing　paradigm　with　the　increasing　popularity　of　digital　cryptocurrencies　such　as　Bitcoin.　Blockchain　technology　is　a　decentralized,　de-trusted,　open　and　transparent　distributed　data　storage　technology　that　can　reduce　the　costs　of　trust　and　achieve　secure　and　reliable　data　interaction.　Big　data　has　been　widely　concerned　and　studied　because　it　contains　great　value,　however,　because　big　data　sets　usually　contain　a　lot　of　privacy-sensitive　information,　extensive　and　in-depth　research　on　privacy　protection　of　big　data　has　not　been　realized.　Under　the　premise,　reasonable　storage　of　big　data　is　an　urgent　problem　to　be　solved.　Under　the　premise　of　analyzing　blockchain　structure　and　access　control,　this　paper　proposes　data　security　storage　protection　architecture　based　on　blockchain　technology　and　access　control　technology,　and　analyzes　the　architecture　in　detail,　and　finally　summarizes　the　paper.　©　2020,　Springer　Nature　Singapore　Pte　Ltd.
