The　traditional　system　of　video　surveillance　interworking　improves　the　efficiency,　resources　utilization　rates　and　management　ability　through　emerging　technology,　such　as:　AI,　Big　data,　etc.　However,　while　video　surveillance　system　interworking,　the　problem　of　video　surveillance　data　leakage,　data　authenticity　cannot　be　verified　still　exists.　Blockchain　is　a　fundamental　trust　techniques,　which　can　solve　the　problem　of　data　not　be　trusted,　data　has　been　tampered,　etc.　This　paper　research　and　proposes　an　application　model　of　video　surveillance　system　interworking　based　on　blockchain　(BVSSI)　and　shows　several　application　scenarios　based　BVSSI.　©　2021　IEEE.
