    摘要： A computer-implemented method comprises training, using a validation set of input, a first classifier to predict when a second classifier will issue a classification error on a particular input, the first classifier generating a number of data buckets based on the validation set of input and populating a threshold lookup table for each data bucket based on a number of thresholds set for the second classifier during the training; storing each threshold lookup table in memory; obtaining a target error rate; obtaining a new input and running the new input through the first classifier, the first classifier selecting one of the data buckets for the new input; and selecting a threshold for the second classifier using the stored threshold lookup table for the selected data bucket and the target error rate.

    摘要： Systems, methods, and software can be used to provide secure inter-vehicle data communications. In some aspects, a method, comprising: receiving, at a security server and from a hardware security processor connected to a system bus of a vehicle, security confidence data of the vehicle, wherein the security confidence data include at least one of version information of a software code executing on a component of the vehicle, diagnostic data information of the vehicle, or data traffic pattern information of the vehicle; determining, at the security server, a security confidence score of the vehicle; receiving, at the security server, a query from a different vehicle; and in response to the query, transmitting the confidence score of the vehicle to the different vehicle.

    摘要： A computer system includes a processor, a communications subsystem, and a non-transitory computer-readable storage medium. The computer-readable medium stores instructions that when executed by the processor adapt the computer system to receive an indication of a second device selected, at a first device, for update; send an indication signalling the second device to send state information about the second device; receive state information about the second device; determine, based on the state information, that the second device is ready to perform an update; send, to the first device, an indication that the second device is ready to perform the update; receive, from the first device, an indication to update the second device; and, send a corresponding indication to the second device. The second device is configured to begin updating in response to such an indication without any direct interaction with it. Related methods and computer-readable media are also described.

    摘要： Systems, methods, and software can be used to provide inter-vehicle data communications for multimedia content. In some aspects, a method is disclosed comprising: receiving, at a first vehicle, a multimedia content request message from a second vehicle, wherein the multimedia content request message indicates a target location at which multimedia content is requested; determining, a current location of the first vehicle; in response to determining that the current location matching the target location, generating the multimedia content; and transmitting, by the first vehicle, the multimedia content.

    摘要： A method and apparatus for determining tampering at a device coupled to a moveable object includes receiving a plurality of orientation states of the device, the plurality of orientation states measured by an orientation sensor, determining, based on the received orientation states, at least two expected orientation states, receiving a further orientation state of the device measured by the orientation sensor, in response to determining that the further orientation state differs from the at least two expected orientation states, generating a tamper alert.
