STOCHASTIC PRIVACY

摘要

A stochastic privacy service provider may provide users with a guaranteed upper bound on a probability that personal data will be accessed while enabling the services to collect data that can be used to enhance its services. Users may receive incentives to become participants in a stochastic privacy program. The stochastic privacy provider may employ one or more probabilistic and decision-theoretic methods to determine which participants' personal data should be sought while guaranteeing that the probability of personal data being accessed is smaller than the mutually agreed upon probability of access. The probability of access may be on a per time basis. The stochastic privacy provider mayaccess coalescenses of the personal data of sets of multiple people, where a maximum probability is given for accessing statistical summaries of personal data computed from groups of people that are of at least some guaranteed size.

1. A method of handling personal data, the method comprising:
providing (710) a personal data utilization probability guarantee, wherein a participant of a stochastic privacy program is guaranteed that personal data of the program participant will be utilized with a probability no greater than the personal data utilization probability guarantee; generating (718) a pool that represents participants of the stochastic privacy program; stochastically selecting (720) a plurality of members of the pool in accordance with the personal data utilization probability guarantees of the respective program participants represented by the pool; and utilizing (606) the personal data of the program participants corresponding to the selected members of the pool.
