Abstract: A method for obfuscating functionality of computer software is disclosed. In an embodiment, the method involves determining a first set of instructions needed to perform a target operation and a second set of instructions for at least one or more additional operations. The second set of instructions is tuned to contain instructions such that, by executing the second set of instructions, the function of the first set of instructions can be performed. Once the first and second sets of instruction are determined and tuned, a code library is created and code fragments in the library correspond to code needed to perform the function of the first set of instructions when executed. Instructions are then added to the second set of instructions such that, when executed, will cause the functionality of the first set of instructions to be achieved.

Abstract: An apparatus for restricting execution of software is disclosed. The apparatus includes a telecommunication device configured to communicate with a wireless device (e.g., an RFID device) using a first wireless communication protocol. The telecommunication device is configured to determine whether or not the telecommunication device is located in an authorized wireless environment, based on wireless devices detected by the telecommunication device. The telecommunication device is also configured to execute a program in response to determining that it is located in an authorized wireless environment. Conversely, the telecommunication device is also configured to inhibit execution of the program in response to determining that it is not located in an authorized wireless environment.
