An installation image for installing an unprotected software product is used to install a protected version of the same product. A protected version of the executable file is embedded in a new installation image with the original installation image, in which the unprotected version of the executable file is damaged so as to be unusable and unreadable. The new installation image causes the original installation image to operate, installing the damaged installation file and other data files. The new installation image then replaces the damaged installation file with the protected installation file.

Post-production preparation of an unprotected installation image for downloading as a protected software product

Techniques are provided for adjusting the number of devices allowed to use a digital product (e.g., software) under a license. In one embodiment, the technique may involve setting the allowed number of devices to a first upper/lower limit for a first time period, and, after the first time period has expired, increasing/lowering the allowed number of devices to a second upper/lower limit for a second time period. The technique may involve, readjusting the allowed number for a third time period, thereby allowing for a changing number of device installations of the digital product.

System and method for adjustable licensing of digital products

Techniques are provided secured communication of data, such as in the context of a public key infrastructure (PKI). In one embodiment, the technique may involve using a private key that is bound to the device requesting the secure data, thereby making it harder for someone to copy, steal or fake. The private key may be generated by adding a filler code to a unique device identifier. The identifier may be based on at least one user-configurable parameter and at least one non-user-configurable parameter of the device.

System and method for device bound public key infrastructure

A method encoded on a data storage medium as executable software for processing data includes steps for providing a scrambling key for scrambling a current piece of information from a plurality of pieces of information, providing with the current piece of information a current identification token from a series of identification tokens, the current identification token to be combined with the scrambling key for scrambling a subsequent piece of information from the plurality of pieces of information, and scrambling the current piece of information using a combination of the scrambling key and a previous identification token from the series of identification tokens to create scrambled current data. A system and an article of manufacture for processing data are also disclosed.

System of dependant keys across multiple pieces of related scrambled information

Installing protected software product using unprotected installation image

A method for detecting an attempted attack on a security system. In one preferred embodiment of the present invention, the method includes the step of retrieving a parameter from a hardware system, wherein the parameter changes during an operation of the hardware system. Then, comparing the retrieved parameter with a previously stored parameter; and, detecting a lack of change between the retrieved parameter and the previously stored parameter. An apparatus and an article of manufacture for detecting an attempted attack on a security system is also disclosed.

Method and apparatus for detection of tampering attacks

A method for authenticating a device including the steps of operating the device to create at least one failure condition; obtaining a measurement based on the at least one failure condition; and, comparing the measurement based on the at least one failure condition with a previously stored measurement based on the at least one failure condition to determine an identity of the device. An apparatus and an article of manufacture for authenticating a device is also disclosed.

Method and apparatus for using imperfections in computing devices for device authentication

A method for authenticating a device including the steps of measuring at least one performance parameter of the device to obtain a measurement; and comparing the measurement of the at least one performance parameter with a previously stored measurement of the at least one performance parameter to determine an identity of the device. An apparatus and an article of manufacture for authenticating a device is also disclosed.

Method and apparatus for using performance and stress testing on computing devices for device authentication

Systems and methods are provided for auditing and selectively restricting software usage based on, for example, software copy counts or execution counts. In one embodiment, the method comprises verifying whether the serial number for a software installed on a computing device corresponds to one of recognized serial numbers, and calculating a copy count (or software execution count) for the serial number. In response to the copy count exceeding a defined upper limit, a limited unlock key may be sent to the device. The limited unlock key may allow the software to be executed on the device for a defined time period, a defined number of executions, and/or with at least one feature of the software disabled.

System and method for auditing software usage

A method for using optical media for identification purpose including the steps of exposing a portion of the optical media to a source of radiation; detecting an imperfection in the portion of the optical media; and, quantifying the imperfection to create a unique identifier. An apparatus for using an optical media for identification purposes, including a light source for exposing a portion of the optical media to a radiation; and, a receptor for receiving the radiation through the portion of the optical media, wherein the receptor measures a change in radiation that is received once the radiation has passed through the portion of the optical media.

Method and apparatus for using imperfections and irregularities in optical media for identification purposes

A system for encoding data is provided. The system includes a number parser that breaks down a field that has many digits into a set of data strings that each has a fixed number of digits. A logarithmic converter is connected to the number parser, and converts each data string into a compressed string that has less than the fixed number of digits. A compiler connected to the number parser and the logarithmic converter receives the compressed strings from the logarithmic converter and forms a new field that has many digits.
