Gamoshi's policy regarding DNT (Do Not Track signals) is described in detail below. The system is reacting to four signals coming in the Inventory's requests.
Device
- In the device object:
dnt - recommended Standard “Do Not Track” flag which is set in the header by the browser:
0 = Tracking is unrestricted.
1 = Do not track.
lmt - Limit Ad Tracking signal commercially endorsed (e.g., iOS, Android).
0 = tracking is unrestricted.
1 = tracking must be limited per commercial guidelines. - In the Reg (Regulation) object:
Coppa - Flag indicating if this request is subject to the COPPA regulations established by the USA FTC.
0 = no.
1 = yes.
User
- In the User object:
yob - year on birth signals that the user's age is 13 or under.
Impacts
The spec specifically calls out these areas relevant for OpenRTB as “Personal Information” that is not to be collected:
Geo-location information is sufficient to identify the street name and name of a city or town. Persistent identifiers when they can be used to recognize a user over time and across different websites or online services.
Gamoshi is making all efforts to follow the IAB recommendations:
- OpenRTB Exchanges and Bidders should:
- Provide a facility for sites to be declared as “child-directed”.
- Implement the regulations object extension.
- Provide facilities within campaigns to target for and against this signal.
- Degrade the Geographic information to be less exact prior to logging or transmission.
- Suppress the assignment and synchronization of identifiers, depending on usage.
Gamoshi additionally manipulates the OpenRTB bid request object as follows:
- Device Object
- Suppress Didmd5, didsha1 device ID fields.
- Truncate IP field - remove lowest 8 bits.
- Truncate ipv6 field - remove lowest 32 bits.
- Geo Object
- Suppress lat and lon fields.
- Suppress the metro, city, and zip fields.
- User Object
- Suppress id, buyer uid, yob, and gender fields.
