    • The present disclosure is directed to secure vehicular data management with enhanced privacy. A vehicle may comprise at least a vehicular control architecture (VCA) for controlling operation of the vehicle and a device. The VCA may record operational data identifying at least one vehicle operator and vehicular operational data recorded during operation of the vehicle by the at least one vehicle operator. The device may include at least a communication module and a trusted execution environment (TEE) including a privacy enforcement module (PEM). The PEM may receive the operational data from the VCA via the communication module, may generate filtered data by filtering the operational data based on privacy settings and may cause the filtered data to be transmitted via the communication module. The filtered data may be transmitted to at least one data consumer. The privacy settings may be configured in the PEM by the at least one operator.

    • Embodiments of the present disclosure are directed toward publication and/or removal of attributes in a multi-user computing environment. In some embodiments, a consumer information manager (CIM) associated with a user of a multi-user computing system may receive a notification, from a dimension authority (DA), of a decrease in a population count of users of the computing system who have published an attribute within the computing system, and may determine whether the user has published the attribute. In response to receiving the notification of the decrease and determining that the user has published the attribute, the CIM may determine a likelihood that continued publication of the attribute will enable identification of the user, compare the likelihood to a threshold, and, when the likelihood exceeds the threshold, remove the attribute from publication. Other embodiments may be disclosed and/or claimed.

    • In one embodiment, a security logic of first portable device is configured to receive first motion sample information from at least one motion sensor of the first portable device and second motion sample information from at least one motion sensor of a second portable device, the first and second motion sample information obtained responsive to training movement of the first and second portable devices by a first user. Based on the motion sample information, the security logic is configured to generate a device pairing value, generate a first confidence value based on the first motion sample information and first reference motion sample information stored in the first portable device corresponding to reference movement of the first portable device by the first user, generate a relationship key pair for a relationship, and communicate the first confidence value and a public key of the relationship key pair to the second portable device using the device pairing value. Other embodiments are described and claimed.

    • Generally, this disclosure provides technologies for collecting ad statistics in a privacy sensitive manner. In some embodiments the technology includes a system which includes a plurality of client devices, each hosting a context information management (CIMM) module in a secure processing environment. Each CIMM may be operable to select ads for display and calculate statistics for each of the selected ads. The CIMMs may generate a vector representative of those statistics, and may encrypt that vector using additive homomorphic encryption. The encrypted vector may be associated with a statistics collection counter, which may be incremented each time an encrypted vector is calculated. Each CIMM may compare the incremented counter value to a threshold, and may distribute the encrypted vector to another CIMM for further statistical tabulation if the incremented value is less than the threshold. In this way, the technologies described may ensure that a minimum statistical sample size is collected prior to the transmission of ad statistics to an ad network or advertiser, potentially maintaining or protecting user privacy.
    • 通常,本公开提供了以隐私敏感方式收集广告统计信息的技术。 在一些实施例中,该技术包括包括多个客户端设备的系统,每个客户端设备在安全处理环境中托管上下文信息管理(CIMM)模块。 每个CIMM可以用于选择要显示的广告并且计算每个所选广告的统计。 CIMM可以生成代表这些统计信息的向量,并且可以使用加法同态加密来加密该向量。 加密向量可以与统计收集计数器相关联,每当计算加密的向量时,其可以递增。 每个CIMM可以将增加的计数器值与阈值进行比较,并且如果递增的值小于阈值,则可以将加密的向量分配给另一CIMM用于进一步的统计表。 以这种方式,所描述的技术可以确保在将广告统计信息传输到广告网络或广告商之前收集最小统计样本大小,潜在地维护或保护用户隐私。
