Abstract: A federated query engine system and method for multiple datasets is enhanced with privacy preserving features. It may, for example, limit the movement of data from one or more of the datasets being accessed. It may use cryptographic long-term keys, enabling fuzzy table joins that do not require a comparison of the plaintext column values. The query plan may leverage the particular infrastructure of the storage system that houses each of the datasets. The query engine receives a standard SQL query, translates the query into a logical plan for performing the query across the multiple datasets, converts the logical plan into physical plans that are specific to the implementational architecture of the multiple datasets, and sends these physical plans to SQL workers located near the data warehouses housing each dataset.

Abstract: A data analytics platform provides secure access to federated data for advanced analytics and machine learning. No raw data is exposed or moved outside its original location, thereby providing data privacy. A coordinator located in the provider cloud communicates with runners in each client data silo. The runners ensure that no raw private data is ever exposed to the coordinator. Silo managers are implemented in the client data silo in order to manage and maintain the client cloud components of the platform remotely. In some embodiments, the platform can anonymize verified models for privacy and compliance, and users can export and deploy secure models outside the original data location.

Abstract: The present invention is directed to a differential privacy platform in which the privacy risk of a computation can be objectively and quantitatively calculated. This measurement is performed by simulating a sophisticated privacy attack on the system for various measures of privacy cost or epsilon, and measuring the level of success of the attack. In certain embodiments, a linear program reconstruction-type attack is used. By calculating the loss of privacy resulting from sufficient attacks at a particular epsilon, the platform may calculate a level of risk for a particular use of data. The privacy budget for the use of the data may thereby be set and controlled by the platform to remain below a desired risk threshold.

Abstract: A diet and activity-monitoring device includes a housing configured to be mounted on the subject and a display integral with the housing for displaying information to the subject. The device also includes a body activity monitor operatively disposed within the housing for monitoring the body activity of the subject, a consumption notation control operable by the subject to indicate food consumption, and a timer operable to output a time indicative signal. The device further includes a processor operable to receive and process the body activity signal, time indicative signal and the food consumption signal, for use in determining a food consumption indicator or a body activity indicator, that is stored in a memory portion of the processor for recall by the subject on the display screen.

Abstract: A diet and activity-monitoring device includes a timer which outputs a time-indicative signal. A body activity monitor monitors the body activity of a subject and outputs a signal indicative of the body activity. A consumption notation control is provided which the subject may operate to indicate when they consume food. An activity calculator receives the body activity signal and determines a body activity level for the subject. A consumption calculator communicates with the consumption notation control and receives the time-indicative signal. The consumption calculator determines and stores the times when the consumption location control is operated.

Abstract: A personal activity monitor adapted to be supported on the body of the user, preferably on the wrist, includes a motion sensor such as an accelerometer to generate electrical signals as a function of body motion. The monitor also includes an electronic clock and a memory for recording signals representative of the motion of the housing and their time of occurrence. User entry keys on the monitor allow the entry of signals representative of the time of food consumption and the beginning and end of exercise activity. Other activity and condition sensors may be supported on the monitor such as pulse rate detector, camera for recording images of food consumed, barcode reader and the like. The output of the memory is useful in weight control and fitness logging systems.
