Claim 19:
20. A non-transitory computer readable medium storing instructions that, when executed by one or more data processing apparatus, cause the one or more data processing apparatus to perform operations comprising:
generating, by an application executing on a client device, a random set of data;
blinding, by the application, the random set of data to generate blinded random set of data;
obtaining data regarding a digital certificate of the application and device trustworthiness data including device data that can be used in assessing trustworthiness of the client device;
providing, to a trust assessment server, the blinded random set of data, the data regarding the digital certificate, and the device trustworthiness data;
receiving, from the trust assessment server, a first set of data including (1) a first indication specifying that the client device is trustworthy, (2) a second indication specifying that the application is authentic, and (3) a digital signature, of the trust assessment server, over a first data item;
validating the digital signature over the first data item;
in response to validating the digital signature over the first data item, unblinding, by the application, the first data item to obtain an unblinded first data item;
confirming that the unblinded first data item matches the random set of data;
in response to confirming that the unblinded first data item matches the random set of data, obtaining, by the application, contextual application data representing a context in which content is provided and interacted with, within the application;
providing, to an application error detection server, the digital signature over the first data item, the first indication, the second indication, and the contextual application data; and
receiving, from the application error detection server, a third indication specifying that the application does not have any errors.
