    摘要： A device that secures a token from unauthorized use is disclosed. The device comprises a user interface for accepting a personal identifier, a processor, communicatively coupled to the user interface device, and a token interface. The token interface includes a token interface IR emitter that produces an IR signal having information included in the PIN. The token IR emitter is coupled to the processor and is further communicatively coupled to a token IR sensor when the token is physically coupled with the token interface. The token interface also includes a shield, substantially opaque to the IR signal, for substantially confining the reception of the IR signal to the token IR sensor. In one embodiment, the shield substantially circumscribes the IR emitter. In another embodiment, the interface also comprises a token interface IR sensor, which allows communications from the token to the device as well.

    摘要： A system and method in which the operating system of the user computer loads the software application and a DLL having a portion of the application execution code stored therein into memory is disclosed. At selected points during its execution, the software application calls the DLL to execute a portion of the application code that was saved into the DLL before delivery to the end user. Since this code is encrypted and the encryption key is stored in a hardware security device and not in the DLL or the software application, the application code portion cannot be executed without recovering the key.

    摘要： The computer-based software protection systems are provided using methods that improve the protection of vendor's software against unauthorized use. A code generator generates randomized protection code, which is then used to protect the application software. Because the code is unique for each protected software, potential crackers have to analyze and crack every instance of the protection, so that generic hack is almost impossible. Some embodiments of the present invention also randomize license verification module, add and randomize a specific anti-hacking code, and randomize the protection code execution sequence(s). The same embodiments can also select which instructions and how many instructions are randomized. Moreover, these embodiments select where the data is being stored, in which register, memory address and stack position, and also randomize variable offsets. Other embodiments of the present invention are used for interpreted code.

    摘要： Apparatus and method for discouraging computer theft. The apparatus and method requires that a password or other unique information be supplied to the computer before the computer BIOS routines can be completely executed. A BIOS memory storing the BIOS routines includes a security routine which will determine whether or not the required password entered by the user, or a known quantity read from an externally connected memory device is present. The security function stored within the BIOS memory also includes an administration function which permits the computer to be either placed in a locked state, thereby requiring password or the known quantity read from an externally connected memory device to be present each time the computer is booted up. The administration function also permits an unlock state which permits the computer boot up process to complete without entering any password or externally supplied quantity. The external memory location is consulted during each boot up sequence, to determine whether the computer has been placed in the locked or in the unlocked state. If the security depends upon the supply of the known quantity from an externally connected memory device, the computer will be inoperable to anyone not in possession of the external memory device. In the event that the external memory location bearing the locked or unlocked code is removed, the security function assumes the computer to be in the locked state, thus frustrating avoidance of the locked state by tampering with the external memory.
