Abstract:
1. A method for creating an activator for processing a content title into executable form, comprising: generating, by a computer system, an activator, the activator including cryptographic data for decrypting content title data, the cryptographic data is encoded in obfuscated bytecode to inhibit unauthorized extraction of the cryptographic data, wherein the obfuscated bytecode implements executable instructions for decrypting content title data and the obfuscated bytecode is consumable by a bytecode interpreter that is configured to interpret and execute the obfuscated bytecode to obtain the cryptographic data for decrypting the content title data; adding authorization data to the activator, the authorization data identifying a time period in which the content title remains in an executable form; sending the generated activator in the form of the obfuscated bytecode to a client; and sending the content title data to the client, the content title data including a downloadable file system that includes files associated with the content and simulated registry values, wherein the content is configured to be executed by using the files stored in the downloadable file system and using the simulated registry values to simulate an installation of the content in a client file system.
