METHOD AND SYSTEM FOR ONLINE TRUST MANAGEMENT USING STATISTICAL AND PROBABILITY MODELING

A method and system to manage security in an online collaborative process are provided. The method includes receiving a requirement containing trustworthiness properties of a participant and establishing one or more trust parameters relating to the trustworthiness properties. In addition, the method applies the trust parameters with a statistics and probability function, such as stochastic process, to derive a trust parameter value. The trust parameter value indicates future development of the trustworthiness properties of the participants. Furthermore, the trust parameters are classified under one or more trust domains. The trust parameters of each trust domain are aggregated to derive a trust domain value. The trust domain value provides a high-level indication of the future development of the trustworthiness properties of the participant. The aggregation may be performed using statistics and probability function. The method also includes collecting feedback regarding the trust parameters so as to adjust the trust parameter values and the trust domain values based on the feedback. The adjustment is made by re-applying the trust parameters values and trust domains values with the respective statistics and probability functions. In addition, the method provides initial trust parameter values and trust domain values for a new participant with no prior record of trustworthiness properties.
