  • Internet profiling
    Patent number: 6839680
    Abstract: A system, method, and various software products provide for consistent identification of web users across multiple web sites, servers and domains, monitoring and capture of data describing the users' web activities, categorization of the web activity data, aggregation of the data into time dependent models describing interest of users and groups over time. Categorization is made with respect to a category tree which may be standardized or customized for each web site. User groups may be defined based on membership rules for category interest information and demographics. Individual user profiles are then created for users automatically based on satisfaction of the user group membership rules. As new data is collected on a user over time, the category interest information extracted from the user's web activity is updated to form a current model of the user's interests relative to the various categories. This information is also used to automatically update group membership and user profile information.

  • Database system with methods for controlling object interaction by establishing database contracts between objects
    Patent number: 5751909
    Abstract: A method for ensuring reliable interactions between principals within a database or between databases. The method involves the creation of database contracts which are, in essence, binding constraints on the behavior of entities within a database system that can be enforced by the system. A database contract is formed when two or more principals agree on the terms and conditions of the contract, and a monitor puts in to place the constraints necessary to enforce the agreed-upon terms and conditions after determining that each of the principals has the requisite authority and ability to carry out the contract.
