Abstract: Techniques for synthetic data generation in computer-based reasoning systems are discussed and include receiving a request for generation of synthetic data based on a set of training data cases. One or more focal training data cases are determined. For undetermined features (either all of them or those that are not subject to conditions), a value for the feature is determined based on the focal cases. In some embodiments, the generation of synthetic data may be conditioned on values of features, preserved features, such as unique identifiers, previous-in-time features, and using the other techniques discussed herein.

Abstract: An apparatus to unblock a security device issued to an end user includes an unblocking service for establishing a secure gateway. A client-side applet securely transfers information among the unblocking service, the end user, and the security device. An agent-side applet securely transfers information between the unblocking service and a security agent. An Unblock Authorization Code (UAC) is securely transferred from the agent-side applet and the client-side applet to the unblocking service. An Unblock Code (UBC) is securely transferred from the unblocking service to the client-side applet. The client-side applet is set to check at a configurable frequency for determining that the UAC is generated. The client-side applet uses the UBC to unblock the security device.
