Claim Text:
1. A computer-implemented method for identifying an on-line advertising conversion, the method comprising: receiving, by one or more computers, a first set of data specifying that a user interacted with an online advertisement and specifying a first clock skew between a clock of a client device at which the user interaction occurred and a clock server that differs from the one or more computers, wherein the first clock skew is determined based on a difference between (i) a midpoint between a current time on the client device when the client device sent a time request to the clock server in response to detecting the user interaction occurred and a current time on the client device when the client device received a response to the time request from the clock server and (ii) a time specified in a response to the time request by the clock server, wherein the specified time corresponds to a time when the clock server received the time request from the client device; receiving, by the one or more computers, a second set of data specifying that an application was installed and specifying a second clock skew between a clock of a client device at which the application was installed and the clock server, wherein the second clock skew is determined based on a difference between (i) a midpoint between a current time on the client device when the client device sent a time request to the clock server in response to detecting the application was installed and a current time on the client device when the client device received a response to the time request from the clock server and (ii) a time specified in a response to the time request by the clock server, wherein the specified time corresponds to a time when the clock server received the time request from the client device; determining, by the one or more computers and based on a difference between the first clock skew and the second clock skew being less than a specified amount, that the application installation is attributable to presentation of the online advertisement; and outputting, by the one or more computers and based on the determination that the application installation is attributable to presentation of the online advertisement, an indication that the online advertisement led to a conversion.
