Project JAL

The Problem• Mobile customers often must provide their number to

untrusted 3rd parties, such as market vendors for a recharge, or for entering a lottery competition• Unfortunately some of these 3rd parties collect customer

numbers and sell them to unsavory characters• It happens that a criminal in a prison purchases a list of

numbers and calsl these customers claiming to know where they live and make threats if they don’t send them money immediately• Out of fear and wanting to avoid a confrontation, many

people give in to the scam and send the cash

The Solution

• Create a system to allow a user to create temporary, anonymous, re-usable access codes that can be shared with an untrusted 3rd party instead of a phone number and deleted later

• Allow easy management (list, create, delete) of access codes via USSD

• Create the back-end anonymous interconnection system that can handle both of the required areas of integration:• Provide voice and recharge connectivity via the anonymized code to

the real customer• Privacy management allowing translation of the anonymized code to

a real customer number to be shared with trusted back-end enablers

Step 1: Create and manage access codes via USSD

Step 2: Share your code with anyone, and they can call, message, or recharge your phone without ever knowing your real phone number
