Interactive file generation and execution

A method comprising:

• receiving, using one or more computing device processors, a non-interactive media file encoded in a first file format;
• receiving, using the one or more computing device processors, first data;
• generating, using the one or more computing device processors, based on the non-interactive media file and the first data, an interactive media file comprising:
• one or more executable instructions based on the first data, and
• an execution engine for enabling a user device to execute the one or more executable instructions;
• wherein the interactive media file is encoded in a second file format;
• and
• transmitting, using the one or more computing device processors, the interactive media file to the user device,
• wherein the user device displays the interactive media file within a display area of the user device or a display associated with the user device,
• wherein an occurrence of a trigger event causes execution, by a processor, of at least one executable instruction of the one or more executable instructions of the interactive media file,
• wherein the processor uses the execution engine for executing the at least one executable instruction of the one or more executable instructions of the interactive media file, and
• wherein the execution, by the processor, of the at least one executable instruction of the one or more executable instructions, causes a display state of the interactive media file to be modified, within the display area of the user device or the display associated with the user device, from a first display state to a second display state,
• wherein the one or more executable instructions, based on the first data and comprised in the interactive media file transmitted to the user device, are updated, after transmission of the interactive media file to the user device, at the user device, based on a communication between the user device and a remote server and based on an update policy verifier and an interactive media file identifier associated with the interactive media file.
