The invention discloses an information divulgement prevention method based on a credible program. The method comprises the following steps of: establishing a
server of each enterprise and public institution, arranging a storage module at each
server, collecting an application program uploaded by a collection terminal, and storing and backing up the application program. The application program called by the terminal cannot be normally used until data of the application program are compared with that of each
server. A credible progress of each
client is collected manually or automatically; the credible progresses are subjected to MD5 value measurement, uniformly uploaded to the servers for storage, recorded and distributed and then monitored by each
client in real time, so that whether the application program used by the
current user is the credible program is judged; and therefore, the
information confidentiality of the enterprise and public institution is guaranteed, and an information divulgement event caused by a program problem is effectively prevented.
