Introduction

Passive Wi-Fi monitoring

Cloud Messaging

Local area messaging mashup

Conclusion

Passive Wi-Fi monitoring

• Wi-Fi probe request• Client (even not

connected) can send requests to AP

• AP can analyze requests

• We can collect MAC-addresses for clients

Advantages and disadvantages

• Does not require special mobile applications • For mobile users it works automatically and transparently• It is anonymous monitoring. MAC address is used for re-identification only. It could be replaced with some hash-code (privacy)• It is not 100% reliable. There is no warranty that Wi-Fi client will send probe request

Cloud Messaging

• Cloud infrastructure from vendor

• Google, Apple, Microsoft, Nokia – own cloud based infrastructures for notifications

• Google message: 4 Kb payload delivery

Google Cloud Messages

Key moments for Cloud Messaging

• Application register with Cloud Messaging• Application provides a key from Cloud

Messaging server (subscribes) to the particular application (Sender)

• Sender saves keys and use them later for delivering notifications

• Key moment – subscription is activated from the mobile application on the particular phone.

Key moments for mashup

• Let us extend the subscription process

• Mobile application (mobile phone, actually) will provide a key for notification and MAC-address for identification

• Sender can compare saved MAC-addresses with the MAC-addresses, collected by the passive monitoring

Key moments for mashup - 2

• Sender can deliver notifications to those, who are nearby only.

• It is real-time detection

• MAC-address is used for the re-identification only. So, it could be replaced with some hash-code (privacy)

Use cases

• Proximity marketing

• Deliver local area messages in retail

• Hyper-local new delivery in campuses. Tested in Lomonosov Moscow State University

• Smart Cities information delivery
