How IMSI works
IMSI is a unique code that authenticates and verifies the SIM cards. The service is necessary to serve customers of banks, as it completely eliminates the possibility of fraud with SIM-cards.
The scenario on which the technology is based is developed in three possible ways:
- Entering new code to the database. This is the first request; there is no information in the database about the subscriber's actions yet.
- Successful code verification. The resulting value is not different from what is recorded in the database. The message is sent automatically.
- Code verification problem. If the received value is not identical to the one specified in the database, the SMS is blocked, and the user receives a notification of refusal to complete the transaction. As a rule, a message also contains a recommendation to call the Bank to get the details.
The algorithm on which authentication is built
The Bank receives SOAP Web-service, which is operated on the technological platform of our company. The software on the Bank's platform is responsible for remote calls. The algorithm allows you to request a SIM-card code by phone number and track where the person is, as well as to obtain the status of Devino Telecom service to confirm its availability. In this case, the bank always starts these operations.
What takes place on the part of the Devino Telecom? A message is delivered to the subscriber via SMPP connection. At this point, Devino Telecom sends a request for a reference value to the Bank. It is updated and becomes the first reference. Later, the whole process is performed simultaneously. The code is sent to the subscriber if the value is identical to the first reference. Otherwise, the person receives a notification specifying that the authenticity of the SIM-card is not confirmed, and the operation was interrupted.
In your account, you can view all the data; activate the procedure for obtaining the code, as well as a detailed log of all the requests made. There is also an option to disable verification for a specific client.
If it is impossible to know the reference value due to technical failures, the absence of a subscriber in the network or the limitations of the mobile operator, the system automatically decides whether the message will be sent. The decision is made based on errors occurred.
