An access certificate is generated and verified according to an access code corresponding to a file requested by a client and feature information of the client, and the file is prevented from being accessed through a stolen, tampered or forged access certificate. The invention concretely discloses an access certificate verification method and device, computer equipment and a storage medium. The access certificate verification method comprises the steps of acquiring an access request sent by a client side, wherein the access requestcomprises an access purpose; obtaining an access code corresponding to the access purpose; generating an access certificate according to the access code and the feature information of the client; sending the access certificate to the client; obtaining an access instruction sent by the client, wherein the access instruction comprises an access purpose, feature information of the client and an access certificate; generating a verification certificate according to the access code corresponding to the access purpose and the feature information of the client; and if the verification voucher is consistent with the access voucher in the access instruction, enabling the access instruction to pass the verification.

Description

technical field [0001] The present application relates to the technical field of identity authentication, and in particular to an access credential authentication method, device, computer equipment and storage medium. Background technique [0002] A certain type of data file is stored on the cloud server, and the owner of the data file can share it with a designated third party. [0003] At present, the commonly used data sharing method generally adopts the access method based on user name and password, which has the following defects: if the user name and password are too simple, it is easy to be cracked by a malicious third party; The data is shared with A, but there is no guarantee that A will not disclose the user name and password to other B, which is what the file owner does not want to happen; if user A obtains the access link of a data file through normal channels, but the If the link is accidentally leaked, the privacy of the data file will be leaked.
