Abstract: Techniques are disclosed relating to application verification. In various embodiments, a computing device includes a secure circuit configured to maintain a plurality of cryptographic keys of the computing device. In such an embodiment, the computing device receives, from an application, a request for an attestation usable to confirm an integrity of the application, instructs the secure circuit to use one of the plurality of cryptographic keys to supply the attestation for the application, and provides the attestation to a remote computing system in communication with the application. In some embodiments, the secure circuit is configured to verify received metadata pertaining to the identity of the application and use the cryptographic key to generate the attestation indicative of the identity of the application.

Abstract: A technique that can be implemented by the digital asset repository, and includes the steps of (1) receiving, from a first application executing on the first computing device, a request to access information associated with a second application managed by the digital asset repository, wherein the request: (i) is transmitted in response to a selection of a user interface that is displayed by the first application and that relates to the second application, and (ii) includes a set of parameters that is provided by a remote server and that specifies at least one utilization requirement pertaining to the second application; (2) receiving, from the second application, an indication that activity associated with the second application has been performed; (3) determining, based on the indication, that the at least one utilization requirement is satisfied; and (4) providing the set of parameters to a metrics manager executing on a second computing device.

Abstract: The embodiments set forth techniques for managing advertisement attributions. A first technique can be implemented by an “app store” application, and include the steps of (1) receiving, from a first user application, a request to view a second user application, where the request includes a set of digitally-signed parameters that are specific to an advertising campaign (provided by an advertisement network) for the second user application that is presented by the first user application. In turn, and in response to identifying that the second user application satisfies at least one criterion, the app store application provides the set of digitally-signed parameters to an advertisement metrics manager that: (i) verifies the set of digitally-signed parameters, and (ii) indicates, to the advertisement network, that business logic should be carried out in association with the first user application and the second user application. A second technique for managing advertisement attributions is also disclosed.

Abstract: A location control subsystem is provided that allows a user of an electronic device to define the granularity used to provide location coarseness. A user can define a coarse location granularity for an application. When a coarse device location is reported to an application, the location can be provided with at least a minimum degree of variable specificity based on the selected location coarseness. When an application is granted a coarse location, the application is to interpret the provided location indicating that the user may be anywhere within a geographic region of variable specificity, as opposed to being close to a center point with a horizontal accuracy based on the precision of the location fix, as when a fine granularity location is provided. In addition to reducing the spatial resolution of the location that is reported to the application, the temporal resolution may also be reduced.

Abstract: Some embodiments provide a method of providing information to a third-party service. From the third-party service, the method receives a request for information regarding a particular device that is transacting with the third-party service. The request includes data encrypted by the particular device that is inaccessible to the third-party service. The method accesses the encrypted data to determine a unique identifier of the particular device. The method uses the unique identifier to determine the requested information. The method provides the requested information to the third-party service without providing an identity of the device to the third-party service.

Abstract: Systems, methods, and computer-readable storage media for maintaining user anonymity in content statistics. A system can first receive a media content request from a client device. The media content request can include a user account identifier and a content identifier. The content identifier can be different and separate from the user account identifier and a device identifier associated with the client device, and the content identifier can identify content presented at the client device. Next, the system can store the user account identifier and the content identifier in separate locations without attributing the content identifier to the user account identifier. In response to the media content request, the system can transmit a media content item to the client device based on the user account identifier. The system can also report the content presented at the client device with the content identifier and without the user account identifier.

Abstract: Systems and method for allowing an identifier value associated with a computing device, and that is delivered to content providers when requesting content, to be altered from that of the unique identifier value associated with the computing device. A computing device will include user interface elements that allow a user to request a new identifier on-demand. In some cases, the user can also configure the computing device to obtain a new identifier value in response to other actions at the computing device or automatically when some type of usage criteria is met. The identifier value is configured to be substantially unique and to be different than a unique identifier associated with the computing device to provide anonymity for the user.

Abstract: In a method of writing data to a file system on a solid state drive, a file stream is opened for writing to a file in the file system. A life expectancy value predicting a length of time the data to be written will be stored in the file system is attached to the file stream. The data is written to the file stream and stored on the solid state storage device according to the life expectancy value attached to the data. In one embodiment, a unique identifier may be used as the life expectancy value for writing a group of related files predicted to be stored in the file system for substantially the same length of time. The life expectancy value may be predicted based on a file type of the file being written. The life expectancy value may be stored as metadata for the file being written.
