Secure Access to Data Over the Internet

Current developments in small, portable computers, and the proliferation of on-line information servers worldwide , will place new requirements on computer software to support appropriate notions of privacy and security. Our research goal is to develop approaches to au-thentication and authorization for databases operating in an open environment, to allow databases to deal appropriately with re...

Using Neural Networks with Limited Data to Estimate Manufacturing Cost

Neural networks were used to estimate the cost of jet engine components, specifically shafts and cases. The neural network process was compared with results produced by the current conventional cost estimation software and linear regression methods. Due to the complex nature of the parts and the limited amount of information available, data expansion techniques such as doubling-data and data-cr...

Access control over uncertain data

Access control is the problem of regulating access to secret information based on certain context information. In traditional applications, context information is known exactly, permitting a simple allow/deny semantics. In this paper, we look at access control when the context is itself uncertain. Our motivating application is RFID data management, in which the location of objects and people, a...
