  • Content protection via online servers and code execution in a secure operating system
    Patent number: 11163859
    Abstract: A computer system comprising a processor and a memory for storing instructions, that when executed by the processor performs a copy protection method. The copy protection method comprises executing a software loop of a first software application in a first operating system. A first call is executed in the software loop to a code portion. A decrypted code portion of the first software application is executed in a second operating system in response to the first call. The code portion is decrypted in response to a successful validation of the first software application.

  • Code protection using online authentication and encrypted code execution
    Patent number: 9177121
    Abstract: Methods for code protection are disclosed. A method includes using a security processing component to access an encrypted portion of an application program that is encrypted by an on-line server, after a license for use of the application program is authenticated by the on-line server. The security processing component is used to decrypt the encrypted portion of the application program using an encryption key that is stored in the security processing component. The decrypted portion of the application program is executed based on stored state data. Results are provided to the application program that is executing on a second processing component.
