A method for the transition is provided from a Boolean masking of a value to be kept secret to an additive masking of the value to be kept secret. The value to be kept secret is present in the Boolean masking as a representation masked with a first Boolean mask and a second Boolean mask. A first additive mask and a second additive mask are determined for the value to be kept secret. A first masking transition is executed in which the first Boolean mask is converted into the first additive mask. A second masking transition is executed in which the obfuscation value is converted into an additive correction value, and a third masking transition is executed in which the second Boolean mask is converted into the second additive mask.

Disclosed is a checksum generation and validation system and associated methods for dynamically generating and validating checksums with customizable levels of integrity verification. The system receives a file with data points defined with positional values and non-positional values, and differentiates a first set of the data points from a second set of the data points. The system generates a checksum based on a combination of two or more values from the positional values and the non-positional values of each data point from the first set of data points, and further based on exclusion of the positional values and the non-positional values of the second set of data points from the checksum. The system may use the checksum to verify the integrity of the data associated with the first set of data points.

As vehicles collect more data in autonomous or semi-autonomous operation, the collected data such as video, navigation and telemetry data, can containing personally identifiable information (PII). The PII may be governed by specific handling requirements or privacy policies. In order to comply with these requirements and policies a method, system and computer readable memory are provided for determining a location of a vehicle to enable determination of an enforcement policy associated with the location of the vehicle. The enforcement policy defines one or more PII objects that are to be filtered from the vehicle data. The PII objects contained within the vehicle data can then be filtered such that the PII objects are not identifiable. The filtered data can then be stored or transmitted to a remote location.

A method for managing personal digital identifiers of a user in data elements stored in a computerized system may include receiving personal digital identifiers for identifying a user. The data elements may be searched for the personal digital identifiers and data elements may be identified as having the personal digital identifiers of the user. One or more candidate personal digital identifiers in the identified data elements may be assigned as one or more common words appearing in the identified data elements when a word count for each of the one or more common words exceeds a predefined threshold. The user may validate the candidate personal digital identifiers, which may be added to the personal digital identifiers of the user. A personal digital footprint of the user including a location in the computerized system for each of the personal digital identifiers in the identified data elements may be stored.

Limiting access to native device capabilities. A method includes, at a container application installed at the computing device, the container application configured to execute hosted script based applications, identifying a hosted application to execute. The method further includes, at the container application, obtaining information identifying a limited set of capabilities from among the native device capabilities indicating which of the native device capabilities the hosted application has been granted access to. The method further includes, at the container application, executing the hosted application and enforcing limits on the hosted application such that the hosted application is only able to access the native device capabilities identified in the limited set of capabilities.

Determining a level of congruence between modality-event characteristics is disclosed. Information can be collected from an event input source via one or more information collection modalities. Modality-event characteristics can be determined from this information. A level of congruence between the modality-event characteristics can be determined to enable initiating a response based on the level of congruence. The level of congruence can be based on satisfying a rule related to congruence between modality-event characteristics, user profile information, etc. The level of congruence can be related to a probability that the several inputs collected for an event, collected by a plurality of modalities, embody characteristics that are associated with the event occurring according to determined notions embodied in the rule and profile. Determining the level of congruence can support assertions that each input, across differing modes of capturing said input, accords with the expected inputs for an event.
