Mobile-click Cheat and Activation cheat phenomenon and early warning

First, click Cheat

Clicking Cheat is a relatively inexpensive and easy way to use a large number of test machines or simulators to send directly, and some are hired or motivated to induce users to do a lot of clicks.
Analyze the log of the click Data, it is not difficult to find that there are generally several phenomena:
1. IP dispersion density
2. Time period repetition
3. Data non-Mobile Send As simulator
4. Unable to access UA information on the mobile side

How to prevent click cheat?
1.Cookie row Weight: On the mobile side, often can also be similar to the PC, add monitoring links, so that you can record the jump to access the page information, you can prevent the same device multiple clicks on the same ad.
2.IP to prevent cheating: When the brush click, certainly not only with the same device, so in addition to the cookie weight, you can also be based on the IP to row weight. Now the Internet is generally dynamic IP, cheaters through the dialer on the offline to achieve the change of IP address, you can be identified by the C-segment IP, such as a large number of 218.175.11.x this same c-segment IP number, you may cheat.
3. Click on the validity period: Limit the duration of the click, in the validity period, the subsequent conversion to the corresponding platform, such as beyond the validity period, is not calculated, generally can be 1 days
4. Exception data blacklist: For some more than a periodic click Source, or non-mobile data click Record, more than a certain range marked as blacklist. For long-term filtration.

Second, activate cheating

Mobile side In addition to click, More is the effect of data, that is, the subsequent activation, registration, payment and other acts are can be monitored, of course, can cheat. Common means are simulated downloads with a click-consistent tester or simulator, as well as modifying device information by mobile manual or technical means, decoding the SDK to send virtual information, simulating download activation, and so on.
The phenomenon of activating cheating, of course, also includes:
1. IP dispersion density
2. Time period repetition
3. Simulator Send
4. The attribution time difference does not conform to the logic etc.

So how to prevent the activation aspect?
1. Equipment Number Weight: The number of equipment can be divided into several aspects:
A) for cheating means manual or simulator repeatedly download activation, it is sure to do the most basic equipment number of weight.
b) To modify the device information for cheating means, to add activation, we need to make clear the unique marking of the device. For example, iOS IDFA can be changed at will, Android domestic cottage many, but also a lot of equipment numbers are duplicates. This makes the equipment number row weight, must have the ability to uniquely mark a device, not only relies on IDFA, Mac and so on such common equipment marking.
2. Activate the IP row weight: As with click, multiple activations of the same IP segment should also be marked as abnormal activation.
3. The attribution time difference is cheating: the attribution difference is when you activate from click to download. In general cheating, fake click and activation is co-exist, he no matter who first who after, met even. So often the time is logically wrong, such as the activation time is earlier than the click Time or the difference is too short. These activations should also be marked as abnormal activation.
4.SDK encryption Protection: The transmission activation of the SDK to encrypt processing, improve its cost of cracking cheating.
Advertisers are the biggest victims of the advertising chain, so many advertisers are trying to protect themselves from cheating. However, this process is often troublesome, manual than the work of more cumbersome, and like the brush device number of this cheating situation, with their own technology to protect it is difficult to do everything. At the same time, marketing is often multi-platform channel concurrent operation, alone with their own strength is indeed difficult. Although cheating is difficult to completely prevent, but we can continue to improve cheaters cheating cost to cheat protection to also data true.
