Abstract
A method and system for rendering a set of computer-readable program instructions on a user device as executable or non-executable. The user device or an intermediary device may transmit an access-token request including a device identifier to a server device. The server device determines whether the device identifier matches a registered device identifier, and if so, transmits an access-token to the user device, or to the intermediary device, which in turn transmits the access-token to the user device. The access-token includes an expiration indicator. Preferably, the expiration indicator is not expired when received by the user device, but expires some time after being received by the user device. The user device executes a first set of program instruction to determine whether the expiration indicator is expired, and if so, renders a second set of program instructions as non-executable, otherwise the second set of program instructions are rendered as executable.
