Yun-Sam Kim, Eun-Sun Cho · 2005
Mobile software industry is suffering from the illegal usage of the software. PKI will not be a solution for small software distribution. We introduce a lightweight but safe method to prevent illegal usage of mobile phone software, by instrumentation on binary for device-identity check. The method is now being implemented on a presumable code on demand (COD) server for WIPI (Wireless Internet Platform for Interoperability).
