<p>The subject disclosure pertains to systems and methods for facilitating detection of click fraud for a pay per click advertising system. A random, unbiased sample of clicks can be generated and used to estimate the occurrence of click fraud within the advertising system. Analysis of the limited sample set reduces expenses in detection of illegitimate clicks. Additionally, instances of click fraud detected within the sample set can be used to estimate the total volume of click fraud for purposes of adjudication and reimbursement of the advertiser, making click fraud detection economically viable. In an aspect, cryptographic techniques, such as public key encryption, can be used in the generation of the random sample set, allowing the advertiser to verify the selection of the sample set.</p> |
