Abstract: A method is provided. The method comprises a computer calculating a sensitivity score based on an assessment of a first message received by a first electronic device from a second electronic device. The method also comprises the computer calculating a trust score based on the first message and previous messages between the first and second electronic devices. The method also comprises the computer calculating a risk score by aggregating the sensitivity score and the trust score.

Abstract: A method is provided comprising a computer posting a work order comprising a first quantity of tasks available for work at a first price per task and a completion deadline for the first quantity of tasks. The computer receives a claim of the order from a first job seeker device, the claim comprising an offer to fulfill the order. The computer accepts the offer and instructs the device to begin work. The computer determines, at a first time before the deadline, a first actual job completion velocity of the order comprising a number of tasks of the first quantity completed at the first time compared to the first quantity. The computer adjusts at least one of the first price per task and the deadline based on comparison at the first time of the first actual and expected completion velocities for that time.
