METHOD FOR SEPARATELY EXECUTING SOFTWARE, APPARATUS, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

The present invention relates to a method for separately executing software, to an apparatus, and to a computer-readable recording medium. The present invention provides a method for separately executing software, comprising the steps of distinguishing an important module from specific software by analyzing a control flow, a data flow, and a module structure through a static binary analysis or runtime profiling (i.e., dynamic analysis), separating the module from the main body of the software, storing the module in a smart card having a secure execution environment, storing the modified main body of the software, in which the module is replaced by an interface code into a user terminal, and co-processing the user terminal and the smart card when using the software, thereby executing the software only if the smart card is coupled to the user terminal. The present invention also provides an apparatus and a computer-readable recording medium. The present invention significantly reduces the burden of software development companies regarding the introduction of a copy protection tool, as well as the possibility of errors caused by the additional change in a user environment resulting from the necessity of having the copy protection tool, and protects the copyright of the software in a simple and clear manner using the co-processing of a client-server system.
