InactiveUS20120054112A1Digital data protectionInternal/peripheral component protectionInternet privacyConfidentiality
Techniques for performing a task while preserving the privacy or confidentiality of information used as input for the task. In one embodiment the task is broken down into smaller tasks (called subtasks or microtasks), which are then outsourced. The input information for each microtask is based upon and is generally a subset of the input information received for the task. The determination of microtasks for the task is performed in such a manner that constraints associated with the task are satisfied. For example, microtasks may be determined for the task based upon risk (e.g., the risk associated with the privacy or confidentiality of the input information being compromised as a result of the outsourcing), quality constraints (e.g., desired quality of the work product resulting from performance of the task), cost constraints, and other constraints associated with the job.
