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 data bases 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 occurence 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 royalities can be calculated based on actual use.

A secure database access system for use by at least one user, said system comprising: an optical storage arrangement located at said user site, said storage arrangement storing at least one encrypted database component of at least one database, said database being adapted for being searched and retrieved in response to search criteria; input means for providing database search criteria in response, at least in part, to user input; searching means, operatively connected to said storage arrangement and to said input means, for searching and identifying a portion of said at least one database that corresponds to said search criteria; reading means operatively connected to said searching means for reading an identified database portion so as to provide digital signals; decrypting means, operatively connected to receive said provided digital signals, for decrypting an encrypted database portion; and control means, operatively connected to at least one of (a) said storage arrangement, (b) said searching means, (c) said reading means, and (d) said decrypting means, for metering at least one of (a) processing, and (b) usage, of at least one part of said at least one database, and for facilitating communicating of information indicative of at least part of said metered at least one of (a) processing, and (b) usage, to at least one location distant from said user.
