  • Patent number: 6986063
    Abstract: A method and system for reducing unauthorized software use include generating a key based on computer-specific information of a computer on which the software is installed and using the key to encrypt an authorization code which enables use of the software on the computer. A representative maintains contact with the software user as a new authorization code from the representative is required after some period of use of the software. The representative encrypts the new password using the key and transfers the encrypted key to authorize use of the software for a next period of use. The encrypted password is a form of digital signature or certificate which is unique to a particular computer and limits use of the software to the particular computer. The key may be generated using various computer-specific information such as the motherboard/processor identification, the number of bad sectors or hard disk identification, and/or the amount of installed memory.

  • Patent number: 6857078
    Abstract: A method for reducing unauthorized software use includes supplying a first authorization code with the software. The first authorization code enables the software on a computer for use by a user for an initial authorized period upon entry by the user. The user is required to contact the representative for retrieval of an additional authorization code. The software is operable during a subsequent authorization period beyond the initial authorization period without further or continual communication with the representative following entry of the additional authorization code. The user chooses manual or electronic registration and provides registration information to the representative prior to retrieval of the additional authorization code. The registration information includes computer specific information.

The first authorization code enables the software on a computer for use by a user during an initial period upon entry by the user. The user then contacts the representative for retrieval of an additional authorization code. The software is operable during subsequent periods without further communication with the representative following entry of the additional authorization code. The user chooses either manual or electronic registration and provides registration information to the representative prior to retrieval of the additional authorization code. Previously stored registration information is compared with the registration information provided by the user to the representative prior to retrieval of the additional authorization code to determine if the user is an unauthorized user.

  • Publication number: 20040225894
    Abstract: Hardware based digital rights management includes designating software for protection via a code or identifier associated with the software and detected by a hardware based authorized representative entity resident on a user computer, network, or device, remotely located relative to the user, or both. Representative hardware based implementations may be in the form of a chip, chipset, PC card, processor, and/or integral with a CPU, preferably supplied on an OEM basis. Authorized representative functions are programmable and/or hard coded. Software/digital content is self-activating/self-authenticating when used in conjunction with a resident authorized administrator. During the first use or transfer of content designated for protection, the authorized representative generates a password or authentication code at least partially based on registration information including user system information and links the code to the content.

  • Publication number: 20040117644
    Abstract: A method for reducing unauthorized use of software includes designating software for protection via a corresponding identifier associated with the software. The identifier is detected by an authorized representative entity that may be resident on a user computer, network, or device, remotely located relative to the user, or both. The software is self-activating/self-authenticating when used in conjunction with a resident authorized representative. During the first use or transfer of the content designated for protection, the authorized representative generates a password or authentication code based on user system information and links the code to the content. Subsequent use or access to the content requires that the current system information at least partially match the system information of the authorized system encoded in the authorization code or codes associated with the content.
