Abstract: The present disclosure provides systems and methods for secure identification retrieval. The method includes retrieving a value of a periodic variable and calculating a plurality of query tokens from a corresponding plurality of client device identifiers and the value of the periodic variable. Each query token is associated with a corresponding client device identifier in a first database. The method further includes receiving a first query token calculated from a client device identifier of the first client device and the value of the periodic variable and identifying a second query token of the calculated plurality of query tokens in the first database matching the first query token. The method further includes, responsive to the identification, retrieving the associated client device identifier and retrieving one or more characteristics of the first client device according to the associated client device identifier. The method further includes transmitting the retrieved one or more characteristics.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for combating false advertising using crowdsourcing. In one aspect, a method includes receiving a false digital component alert indicating that a digital component presented at a client device includes false information, validating the false digital component alert based on a public key to verify digital signature included in the false digital component alert matching the public key of stored attestation tokens specifying presentation and interaction data for the digital component. In response, adding the false digital component alert to an aggregated report. Based on a false alert ratio, determining that a magnitude of validated false digital component alerts in the aggregated report meets a threshold, and triggering a false digital component mitigation response including providing a false information warning with the false digital component to one or more client devices or digital component provider.

Abstract: Systems and methods described herein can relate to a web browser-based application programming interface (API) that can control the authorization of data transmissions within a networked environment. The system enables content items displayed in a web page to make a call to the browser to request that the browser register the content item with the browser. The web browser can control the network transmissions to content items approved or authorized by the web browser. The system can reduce the number of transmissions that do not result in content for the client device—saving bandwidth and computational resources for the client device.

Abstract: The systems and methods described herein can enable the indirect transmission of session data between different domains. The system can pass the session data through a hashing function so that the data from a given domain remains private and secure to the specific domain. The system can generate clusters of associated domains for a given client device that the system can use to maintain a session between the client device and the domain.

Abstract: The present disclosure provides systems and methods for content quasi-personalization or anonymized content retrieval via aggregated browsing history of a large plurality of devices, such as millions or billions of devices. A sparse matrix may be constructed from the aggregated browsing history, and dimensionally reduced, reducing entropy and providing anonymity for individual devices. Relevant content may be selected via quasi-personalized clusters representing similar browsing histories, without exposing individual device details to content providers.

Abstract: The present disclosure provides systems and methods for automatically detecting third-party re-identification of anonymized computing devices. The method includes retrieving a log of content items provided to anonymized computing devices identifying a first content item provided to a plurality of anonymized computing devices within a first predetermined time period; for each anonymized computing device of the plurality of anonymized computing devices, generating a set of identifications of second content items retrieved by the anonymized computing device prior to receiving the first content item within a second predetermined time period; determining that signals or combinations of signals with a highest predictive ability between a first set of identifications and a second set of identifications exceeds a threshold; identifying a provider of the first content item; and if the signals or combinations of signals with the highest predictive ability exceeds the threshold, preventing, transmission of a request of an anonymized computing device for a content item to the identified provider.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for detecting errors in a client device and its associated applications while preserving the privacy of the user of the device. Methods can include obtaining and blinding contextual application data for an application on a device. Data regarding the application's digital certificate and device trustworthiness data are obtained and provided to a trust assessment server along with the blinded data. This server can provide indications that the device is trustworthy and the application is authentic, and can digitally sign the blinded data. The digital signature can be validated and the unblinded contextual application data can be obtained. If the unblinded data matches the contextual application data, the application can provide the digital signature, the indications, and the unblinded contextual application data to an error detection server, which in turn can indicate the application does not have errors.

Abstract: At least one aspect is directed to improving the performance of real-time verification of online identity. The issuer computing system can receive a request to generate a composite token, the composite token configured to authorize certain verifying parties to authenticate a first-party token comprising information about a client. The issuer can generate a composite token using cryptographic keys and distribute it to the client, who can distribute it to other content item networks. The verifying parties can receive the composite token from the content item networks, use a cryptographic key verify the authenticity of the token corresponding to the client device, and use the token to further process content item operations. The system can distribute the cryptographic keys prior to the generation and verification of the composite token, and as such allow the parties to verify the composite token in real-time without contacting outside verification parties.

Abstract: Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a method for providing content. A linking is provided of identifiers for users or devices known to a content delivery service. Each identifier is associated with the user or device in a specific context. The linking includes first and second identifiers. A request for content is received that includes either the first or second identifier. Bidders in an exchange are identified that have expressed an interest in bidding on a content delivery opportunity associated with the user or the device. For each bidder, a relative value is determined for a respective bidder for the opportunity to present content to the user or device in association with each identifier known to the bidder. For each bidder, a real-time bid request is generated in the exchange that includes the highest value identifier for submission to a respective bidder.

Abstract: The present disclosure provides systems and methods for client-side anonymized content selections. The method includes collecting a plurality of identifications of content selection lists, each content selection list associated with the first device and at least one other device. The method includes selecting a first subset of the content selection lists, responsive to a total number of unique device associated with a plurality of content selection lists of the first subset exceeding a threshold. The method includes transmitting a request for an item of content, the request comprising identifications of the content selection lists of the selected first subset. The method includes receiving a first item of content selected by the content server based on the content selection lists of the selected first subset.
