Embodiment Construction

[0029] In general, this document describes cryptographic techniques used to prevent fraud when determining event-level and aggregated network measurements. For example, the techniques described in this document can prevent fraud in determining event-level and aggregated impression and conversion measurements of digital components for various types of conversions. The cryptographic techniques described in this document may also protect user privacy, for example, by preventing all entities from being able to track or aggregate user data received from a user's client device.

[0030] System Overview

[0031] figure 1 is a block diagram of an example environment 100 in which an aggregation server 180 determines aggregated network measurements. The example environment 100 includes a data communications network 105, such as a local area network (LAN), a wide area network (WAN), the Internet, a mobile network, or combinations thereof. Network 105 connects client device 110 , publi...

Abstract

Methods, systems, and apparatus, including a method for determining network measurements. In some aspects, a method includes receiving, by a first aggregation server and from each of multiple client devices, encrypted impression data. A second aggregation server receives, from each of at least a portion of the multiple client devices, encrypted conversion data. The first aggregation server and the second aggregation server perform a multi-party computation process to decrypt the encrypted impression data and the encrypted conversion data. Each portion of decrypted impression data and each portion of decrypted conversion data is sent to a respective reporting system.

Description

Background technique [0001] Client devices transmit data over a public network, such as the Internet. These communications may be intercepted and / or altered by entities other than the intended recipients. Additionally, the entities may forge network identities and send data that appears to originate from these forged network identities. An example of such forgery is a Sybil attack, in which an entity creates a network identity to undermine the reputation system of a peer-to-peer network. Contents of the invention [0002] This specification describes techniques related to determining network measurements in a manner that prevents fraud and preserves user privacy. [0003] In general, an innovative aspect of the subject matter described in this specification can be implemented in a method comprising: receiving, by a first aggregation server, presentation data from each of a plurality of client devices, for for each exposure of a recorded digital component, the exposure dat...
