Ubiquitous questionnaire is to provide users with E-questionnaire services anytime and anywhere such that one can use E-questionnaire servers without even thinking about them. An E-questionnaire server for ubiquitous questionnaire should provide guarantees to satisfy any user-specified requirement on information assurance, privacy, and security because some questionnaires may concern organization secrets as well as personal privacy, and some questionnaires such as E-voting or E-testing must impose restrictions on and provide assurance to respondents, voters, and/or testees. Until now, there is no detail requirement analysis for information assurance, privacy, and security in ubiquitous questionnaire. To implement an E-questionnaire server for ubiquitous questionnaire, this paper presents a requirement analysis for information assurance, privacy, and security in ubiquitous questionnaire. The paper identifies all participants and their information assets in ubiquitous questionnaire with a general purpose E-questionnaire server that can be used not only an E-questionnaire server but also an E-voting server and an E-testing server, gives a threat analysis of and a requirement analysis for information assurance, privacy, and security, and investigates technical issues for implementing facilities satisfied the requirements.
