Resumen
The article describes the Lucent Personalized Web Assistant (LPWA), a software system designed to address Internet users' concerns. Users may browse the Web in a personalized, simple, private and secure fashion using LPWA-generated aliases and other LPWA features. LPWA generates secure, consistent, and pseudonymous aliases for Web users. Each alias consists of an alias username, an alias password and an alias email address. The alias email addresses allow Web sites to send messages to users and enable effective spam filtering. LPWA forwards mail addressed to the alias email address to the actual user. LPWA allows users to filter incoming messages based on the recipient address, which is an effective method for detecting and blocking spam. In this way, the LPWA site does not attract break-ins, and the LPWA service may be replicated easily. The absence of state information also implies there are no records to which an outside agency can demand access. INSET: Usage of LPWA.
