The target user may be a user in a preset user list or a preset user set. Such as a user interacting with the blockchain system. The certification file may be a file pre-uploaded by the target user in various formats, such as a text file, a video file, an image file, and the like. The attribute information of the deposit certificate file may include, but is not limited to, at least one of the following: the file management method comprises the following steps of version information of a file, a file name, a type format of the file, a length of the file, a file storage channel source, a name of an operator of the file, submission and storage time of the file, a storage period of the file, an encryption identifier of the file, a message key of the file, a transformation password of the file and the like.
In this embodiment, based on the certificate-storing file and the attribute information received in step 201, the electronic device may number the certificate-storing file and the attribute information to obtain a first certificate-storing number of the certificate-storing file.

The basic process of the cryptographic calculation is to process a file or data, which is originally in plaintext, according to some algorithm to make the file or data become an unreadable segment of code, which is generally called "ciphertext", so that the original content can be displayed only after a corresponding key is input. The above-mentioned cryptographic Algorithm may be various types of algorithms, such as a symmetric encryption Algorithm, an asymmetric encryption Algorithm, a Hash Algorithm, a Secure Hash Algorithm (SHA), and the like.

After receiving the first deposit number and the first file identifier, the blockchain system may store the first deposit number and the first file identifier in the blockchain system in the form of an item in a certain block of the blockchain account book through blockchain calculation. The inlier indication may be an identification of an item stored within a block (the block being determined by the block height) within the blockchain system, by which the storage location of the item (e.g., transaction, access, etc.) in the blockchain system may be located. It should be noted that the above-mentioned blockchain technology and technical terms related to the blockchain technology (such as book block height, etc.) are well-known technologies and well-known terms widely studied and applied by those skilled in the art, and are not described herein again.
