A “return on investment”digital database usage metering, billing, and security system includes a hardware device which is plugged into a computer system bus (or into a serial or other functionally adequate connector) and a software program system resident in the hardware device. One or more database
A “return on investment”digital database usage metering, billing, and security system includes a hardware device which is plugged into a computer system bus (or into a serial or other functionally adequate connector) and a software program system resident in the hardware device. One or more databases are encrypted and stored on a non-volatile mass storage device (e.g., an optical disk). A tamper-proof decrypting device and associated controller decrypts selected portions of the stored database and measures the quantity of information which is decrypted. This measured quantity information is communicated to a remote centralized billing facility and used to charge the user a fee based on database usage. A system may include a “self-destruct”feature which .disables system operation upon occurrence of a predetermined event unless the user implements an “antidote”－instructions for implementing the antidote being given to him by the database owner only if the user pays his bill. Absolute database security and billing based on database usage are thus provided in a system environment wherein all database access tasks are performed at the user\s site. Moreover, a free market competitive environment is supported because literary property royalties can be calculated based on actual data use.
A database protection system for securely distributing a database, said system preventing unauthorized use of at least a portion of said database, said system comprising: at least one storage medium physically disposed at a customer\s site, said storage medium storing at least a portion of said data
A database protection system for securely distributing a database, said system preventing unauthorized use of at least a portion of said database, said system comprising: at least one storage medium physically disposed at a customer\s site, said storage medium storing at least a portion of said database, said database containing properties, at least a portion of said database being encrypted, said encrypted portion requiring processing with at least one key for authorized use; and a digital processing arrangement, disposed at said customer\s site and operatively connected to said storage medium, said processing arrangement including: (a) control logic allowing said customer to select and use at least one part of at least one of said database properties, said control logic selectively processing, using said at least one key, at least one part of said encrypted portion of said stored database; (b) means for storing, at said customer\s site, at least one value related to metering of at least one aspect of use of at least a portion of said database properties, said storing means including means for storing, at said customer\s site, limit information related to limiting at least one aspect of said customer\s use of said database properties, wherein at least a portion of said stored limit information is accessible to said customer; and means for determining payment required from said customer for use of at least one portion of said database.
