Abstract
Hanford Engineering Development Laboratory (HEDL) is developing a computerized accountability system that addresses the concerns of data access and data protection. The system utilizes a distributed processing network with transaction oriented software. Microprocessor controlled data accumulation stations are utilized which permit data editing to reduce errors, while maintaining several levels of backup protection. Software changes are allowed only after thorough review, protected by passwording, and are overchecked by audit. Protection against misuse by unauthorized individuals utilizes extensive physical security of the computer and the remote terminals. The positive identification devices and strict software control ensure that individuals cannot subvert the system without leaving an audit trail of their actions. This serves as a deterrent against malevolent acts by the authorized user.
