  • Publication number: 20220019689
    Abstract: In some implementations, a computing system can be configured to perform personalized content item selection in a privacy preserving manner. In some implementations, user privacy can be protected by performing the personalized selection of content items on the user's device. For example, the computing system can include a client device configured to select content items from a collection of candidate content items received from a server device based on a user profile generated and stored on the client device. In some implementations, user privacy can be protected when performing the personalized selection of content items by sending an anonymous, or approximate, user profile (e.g., class profile) to the server device. For example, the computing system can include a server device configured to select content items from a collection of content items based on a class profile representing a group of similar user profiles received from the client device.

  • Publication number: 20210406531
    Abstract: This disclosure describes techniques for providing instructions when receiving biometric data associated with a user. For instance, an electronic device may detect a portion of a user, such as a hand. The electronic device may then determine locations of the portion of the user relative to the electronic device. Based on the locations, the electronic device may cause a visual indicator to provide instructions to the user for placing the portion of the user at a target location relative to the electronic device. For example, the visual indicator may emit light indicating that the portion of the user is off-centered, angled, too low, and/or too high. After providing the instructions and determining that the portion of the user is at the target location, the electronic device may capture at least an image of the portion of the user and use the image to identify an account.

  • Patent number: 10789696
    Abstract: The present disclosure relates to a method for image patch selection for training a neural network for image quality assessment. The method includes receiving an input image and extracting one or more image patches from the input image. The moment of the extracted image patches is measured. There is a decision to accept or decline the extracted image patches according to the measured moment. Additional image patches are extracted until a minimum number, Nmin, of extracted image patches are accepted. Alternatively, selection criteria are adjusted until the minimum number of extracted image patches are accepted. The selected image patches are input into a neural network with a corresponding image quality value of the input image, and the neural network is trained with the image patches and image quality value. Also provided is a method for image quality assessment using a neural network trained as set forth above.

  • Publication number: 20200302147
    Abstract: A biometric input device includes a sensor assembly that generates images of a user's palm that is within a field of view (FOV) using an image sensor behind a polarizer with a first polarization. The palm within the FOV is illuminated at different times with light having the first polarization and the second polarization. The images are acquired using polarized light and provide images of surface and subcutaneous features. The images may then be processed to identify the user. The device may include a touchscreen to provide information to the user or receive input from a user. The device may include a stand to mount the device at a convenient location, such as at an entry portal, point of sale, and so forth.

  • Publication number: 20200192954
    Abstract: In some implementations, a computing system can determine how important an investment identifier is to a content item that mentions the investment identifier. For example, a content item may describe a story, event, etc., related to an investment identifier. The content item may mention the investment identifier by mentioning the investment identifier, proxies for the investment identifier, or other equivalents associated with the investment identifier. The computing system can determine locations in the content item where the investment identifier is mentioned and/or how frequently the investment identifier is mentioned. Based on the locations and/or frequency of mentions, the computing system can determine an importance score that represents how important the investment identifier is to the story described by the content item. The importance score can be stored in metadata for the content item and used when determining which content items to present to a user.

  • Publication number: 20200193056
    Abstract: In some implementations, a computing system can deliver personalized content while preserving user privacy. For example, the computing system can include a content server that filters, deduplicates, and generates clusters of content items (e.g., articles, news stories, etc.) that are relevant to an investment identifier received in a request from a client device. The content server can send the clusters of content items to the requesting client. Upon receiving the clusters of content items, requesting client device can evaluate the content items based on user preferences stored on the user device and select a representative content item from one or more content item clusters. The selected content item can then be presented on a display of the user device. Thus, personalization of content item selection and presentation can be performed without distributing user preference data outside of the user device thereby preserving user privacy.
