| 20080229115 | PROVISION OF FUNCTIONALITY VIA OBFUSCATED SOFTWARE - In an example embodiment, executable files are individually encrypted utilizing a symmetric cryptographic key. For each user to be given access to the obfuscated file, the symmetric cryptographic key is encrypted utilizing a public key of a respective public/private key pair. A different public key/private key pair is utilized for each user. Obfuscated files are formed comprising the encrypted executable files and a respective encrypted symmetric cryptographic key. The private keys of the public/private key pairs are stored on respective smart cards. The smart cards are distributed to the users. When a user wants to invoke the functionality of an obfuscated file, the user provides the private key via his/her smart card. The private key is retrieved and is utilized to decrypt the appropriate portion of the obfuscated file. The symmetric cryptographic key obtained therefrom is utilized to decrypt the encrypted executable file. | 09-18-2008 |
| 20090319761 | HARDWARE CONSTRAINED SOFTWARE EXECUTION - Restricting execution by a computing device of instructions within an application program. The application program is modified such that execution of the selected instructions is dependent upon a corresponding expected state of one or more hardware components in the computing device. In an embodiment, the application program is modified to place the hardware components in the expected states prior to execution of the corresponding selected instructions. Creating the dependency on the hardware components prevents the unintended or malicious execution of the selected instructions. | 12-24-2009 |
| 20090327711 | AUTHENTICATION OF BINARIES IN MEMORY WITH PROXY CODE EXECUTION - Presented is an anti-tampering method that validates and protects specific sections of a binary file. In one embodiment, this method permits a proxy engine to execute (via emulation by a virtual machine) the protected code on behalf of the binary in kernel mode upon successful completion of an integrity check. The integrity check can optionally check only the specific parts of code that the developer wishes to validate. The integrity check can cross binary boundaries. Moreover, the integrity check can be done on a hard drive or in memory. Furthermore, since the encrypted code is executed by the proxy engine in kernel mode, hackers are further deterred from modifying the code. Additionally, a method of creating a protected binary file is described herein. | 12-31-2009 |

| 20080250550 | Sports helmet with quick-release faceguard connector and adjustable internal pad element - The present invention is directed to an improved sports helmet including a quick release connector assembly for the faceguard that allows for rapid disconnection of the faceguard from the helmet shell. The connector includes a bracket, and a coupler mechanism featuring an elongated pin, a head component, a spring, a retractable engaging element and a washer. The connector assembly is moveable between a use position wherein the faceguard is secured to the shell by the bracket and the coupler mechanism, and a released position wherein the bracket and the faceguard are disconnected from the shell. An inwardly directed actuation force that lacks a rotational component is applied to the elongated pin to move from the use position to the released position. In addition, the sports helmet includes an adjustable pad assembly comprised of an inflatable bladder and a pad member, wherein the bladder displaces the pad member towards the center of the shell. Once sufficiently displaced, the pad member, which includes a molded pad element, cradles a portion of the helmet wearer's skull. | 10-16-2008 |
