INFORMATION PROCESSING DEVICE AND METHOD FOR PREVENTING UNAUTHORIZED APPLICATION COOPERATION

摘要

An information processing terminal (40) includes: a network control unit (250); an installation control unit (260); a process control unit (200) for starting up an application and establishing cooperation among applications including the application; an access-history map updating unit (290) for updating an access-history map (281) which represents history information on an access relationship among the applications when a request is made to start up the application or to establish cooperation among the applications; and an unauthorized-cooperation-of-applications control unit (220) for (i) determining whether or not an unauthorized cooperation, which is directed at sensitive information kept secret, is established among the applications with reference to information obtained from the access-history map (281) and an application authorizing list (271), and (ii) controlling execution of the application using an application execution control technique in the case where a result of the determination shows that the unauthorized cooperation is established.
