Target object authentication method and device

The invention provides a target object authentication method and device, and the method comprises the steps: triggering an authentication request when an operation request of a user for a target object is received, the authentication request is used for calling an authentication service in an authentication software development kit SDK, and the authentication service is used for determining whether the user has the authority of operating the target object; according to a dependency mode of the label of the target object, controlling the authentication service to obtain the label of the target object, the dependency mode being used for representing a storage mode of the label on which the target object depends; and controlling an authentication service to determine an authentication result of the target object according to the label of the target object. The label of the target object is obtained by calling the authentication service, so that when the label is added to the target service, only the software dev
