Abstract

The application relates to a document distribution method, a document distribution device, a computer device and a readable storage medium. The method comprises the steps of obtaining a pre-built initial document reading application, embedding a portable document format document to be distributed and an identification association rule of the portable document format document into the initial document reading application to obtain an intermediate document reading application, configuring a security access policy of the portable document format document in the intermediate document reading application to obtain a target document reading application, packaging the target document reading application into an executable file and forwarding the executable file to target equipment, enabling the target equipment to run the target document reading application based on the executable file, positioning the portable document format document based on the identification association rule through the target document reading application, and calling the portable document format document and displaying based on the security access policy. By adopting the method, the document distribution safety can be improved.
