摘要

Computer-implemented methods and systems for searching network information through the use of user identification information, user preference information, and search topic information embedded in predetermined web sites. At least one of the user identification information and the user preference information may be collected from the user (202b) through the use of a questionnaire, encrypted, and stored (202c) under a user profile (205). Search information may be received (250a) from the user, encrypted, and utilized in performance of the network search by matching (250b) at least a portion of the encrypted search information with encrypted search topic information located in the predetermined web sites. The search may include matching (250b) at least a portion of the encrypted user identification information and/or the encrypted preference information with the encrypted search topic information located in the predetermined web sites.
