SIM Binding at 1Kosmos (Subscriber Identity Module – Binding)

1Kosmos BlockID SIM binding is achieved during account registration in the 1Kosmos BlockID app. The user will click on an email invite from the institution, which will open the BlockID app.

The user is then challenged to verify their phone number. The BlockID platform uses a combination of SIM detection and SMS verification to validate a user’s mobile number against the number registered with their service provider. Upon successful validation, the customer is allowed to add a new account with the registered device as an authenticator all through the BlockID app.

SIM binding helps reduce fraud, especially in the Internet retail banking sector, where vulnerable customers can be duped into allowing unauthorized entities to register the app and take over the account.

SIM Binding Administration

The 1Kosmos customer (bank, payment provider, enterprise, etc.) generates an email in BlockID console that contains a link to send to end users. When the recipient (consumer, employee, etc.) clicks on the link, it opens the BlockID app, which initiates a process to detect the presence of a single or dual SIM. The user is then prompted to choose the SIM that is registered with their service provider or employer. BlockID then validates the SIM and phone number by matching the phone number on record with the service provider or employer. If validated, then the account, user, and device are linked.
