Hashed Device ID Targeting

At Eskimi the key element is to provide clients privacy safe solutions. This is why Eskimi can provide clients to use their hashed first party data which provides privacy that clients are looking for. 

 

Hashed first-party data

Eskimi supports only sha256 hashing. This is a well known cryptographic hash that changes 40 symbols of device ID to 64 symbols. 

Example of unhashed device ID:

00001928-4f63-4923-8ce0-a1e2c2517385

Example of sha365 hashed device ID:

335a0a471e13c7773712a038576f6186c7df6975ee3f91500c97112a44135e0f

 

Why hashed first-party data is important?

 

Privacy. They key goal of hashed first-party is to ensure privacy for the data that clients share. By providing the opportunity to upload hashed device IDs Eskimi provides privacy first solution to the clients.

Manual Appsflyer Audience. Hashed first-party data upload enables advertisers to manually upload audience from Appsflyer. This wasn't possible before as Eskimi was able to only take up unhashed device IDs. While now clients can take their first-party data from Appsflyer and upload it on Eskimi dashboard and use the data during programmatic advertising. 

 

How hashed first-party data is uploaded?

Hashed first-party data is uploaded as unhashed. In Eskimi dashboard you have to go to:

Tools -> Audiences -> Add Audience -> Under Audience Type select: User IDs list -> Upload a .csv file of hashed device IDs -> check Hashed device IDs (as in the example). By doing so you will inform the system that you uploaded hashed device IDs which will make the matching easier.

After the audience is created it will take around 15 minutes for the system to do the matching. After that audience can be added as targeting. 

Keep in mind that clients still can only use hashed device IDs so the uploaded audience will be compatible with targeting that uses device IDs (app, operator, device and etc.)
