TLDR
In this article, 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 resident in the hardware device.Abstract:
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.read more

Method and system for providing document retention using cryptography
TL;DR: In this paper, the security criteria can pertain to keys (or ciphers) used to secure electronic files (namely, electronic documents), or to unsecure (e.g., decrypt) electronic files already secured.
Patent
Method for computer network operation providing basis for usage fees
TL;DR: In this article, a computer network having a requesting node and a providing node permits data transfer there between when permitted by an authorizing node, and reports generated in response to data transfers are reconciled at a reconciliation node to improve the accuracy of payments collected and paid for use of the data.
Patent
Protecting encrypted files transmitted over a network
TL;DR: In this article, an improved system and approaches for protecting secured files when being used by an application (e.g., network browser) that potentially transmits the files over a network to unknown external locations are disclosed.
Patent
Method and apparatus for tracking client interaction with a network resource
Owen Davis,Vidyut Jain +1 more
TL;DR: In this paper, a method for monitoring client interaction with a resource downloaded from a server in a computer network includes the steps of using a client to specify an address of a resource located on a first server, downloading a file corresponding to the resource from the first server in response to specification of the address, using a server to acquire client identifying indicia from the client, and uploading the amount of time determined by the first executable program to a third server.

Software distribution system
TL;DR: In this paper, the authors propose a software authorization system where a software can be authorized for use a given number of times by a base unit after which the base unit (computer, videogame base unit, record player, videorecorder or videodisk player) cannot use that software until the manufacturer sends an authorization for additional uses to the user's base unit.
