| Zusammenfassung: | The embodiment of the invention provides a data storage verification method and device, and the method comprises the steps: generating first data fingerprint information according to first storage data information and auxiliary information, and sending the first data fingerprint information to a block chain, so as to obtain data fingerprint certificate information fed back by the block chain; if storage data verification is carried out, generating second data fingerprint information according to the second storage data information and the auxiliary information, and sending the data fingerprintcertificate information to the block chain to obtain first data fingerprint information fed back by the block chain; and comparing the first data fingerprint information with the second data fingerprint information to obtain verification result information. According to the method, the data fingerprint information is generated through the preset algorithm, and through comparison of the second data fingerprint information |
