Abstract: A system and a method for distributing and redeeming coupons through mobile devices of consumers are disclosed. Consumers submit a coupon and purchase proof to the redemption server through mobile devices. Once the purchase information is confirmed, a reward is granted to the consumers along with a survey with questions about consumer demographic information and product related questions. The consumers' answers to the survey questions help target the future coupon distributions.

Abstract: A job is divided into tasks belonging to various levels in a hierarchy such that the tasks of one level of the hierarchy depend on the performance of the tasks of another level. The divided tasks are assigned to the respondents and, once the respondents' responses have been determined to be sufficiently accurate, the responses are assembled into a final result. The respondents may be rewarded for completion of their assigned tasks, and the rewards may be structured such that the rewards for the completed tasks create an informal hierarchy amongst the respondents.

Abstract: A system receives from a client a job comprising confidential information. The system then distorts the confidential information associated with the job. Next, the system divides the job into multiple discrete tasks such that the distorted confidential information is further divided and the confidential information cannot be deciphered from an individual task. The tasks are then delegated to respondents in different geographical locations with different social preferences. Because of these differences the respondents are unlikely to communicate information about their job with each other. The respondents receive the job securely through their electronic devices, perform the delegated tasks, and provide the system with responses to the tasks through the devices. The system receives the responses for individual tasks, deduces a unified job response from the received responses and transmits the unified response to the client.

Abstract: A job is divided into multiple discrete tasks that can be performed by multiple different workers of a distributed workforce. The tasks are assigned to the workers through their mobile phones or other communication devices, and the workers perform the assigned tasks and provide responses to the tasks through the devices. Workers are compensated, in part, based in part on the quality of their responses. Once the workers' responses have been determined to be sufficiently accurate, the responses are assembled into a final result. To manage the distributed workforce, the system stores information for each worker, such as an identification of the worker, the tasks previously completed by the worker, and the quality of performance of those tasks. The stored worker information is used to assign tasks to workers, to compensate workers, and in general to manage the workforce.

Abstract: Portable communication devices, such as Bluetooth enabled cellular phones, communicate with and identify like devices that are nearby, and send notification messages to a remote server. When a notification message is received at the server identifying two devices that have come within range of one another, the server compares the profile data associated with each of the two identified devices and facilitates communications between the devices when appropriate.
