KB Kookmin Bank Surpasses 3.6 Million Subscribers for 'KB Mobile Certificate'

[Asia Economy Reporter Kangwook Cho] KB Kookmin Bank announced on the 26th that the number of subscribers to the KB Mobile Certificate exceeded 3.6 million within 10 months of its launch.

The KB Mobile Certificate, developed independently by KB Kookmin Bank to replace the public certificate, is a private certificate with advantages in security and convenience.

Using the KB Mobile Certificate, even first-time customers can conduct transactions via mobile without visiting a branch. The issuance time takes about one minute, and instead of complicated passwords, customers can easily log in by choosing the most convenient method such as pattern, fingerprint, or Face ID (for iPhone users). Unlike other certificates, it has no expiration date.

When conducting financial transactions with the KB Mobile Certificate, transactions are completed by entering only a simple 6-digit password without the need for security cards or OTP, greatly enhancing customer convenience. To protect customers' financial assets, additional identity verification procedures such as ARS authentication are required when processing transactions above a certain amount.

KB Mobile Certificate is the only one among domestic banks that applies security technology not only to software but also to hardware. By storing the certificate in a separate secure area called TEE (Trusted Execution Environment), stability and reliability are enhanced. To this end, the TAP (Trustonic Application Protection) solution from the UK security company Trustonic was applied, and the algorithm verifying the certificate’s validity and password was developed with KB Kookmin Bank’s own technology to strengthen stability and security.

KB Kookmin Bank is also expanding the scope of use of the KB Mobile Certificate. Unlike other private certificates developed focusing only on mobile banking, it allows linked login on PC-based internet banking. Additionally, KB Mobile Certificate login is available on the KB Insurance app. The bank is building an integrated authentication environment within the KB Financial Group to enable financial transactions across other KB Financial Group affiliates.

A KB Kookmin Bank official said, "With the amendment to the Electronic Signature Act passing the National Assembly, we plan to continuously expand the scope of mobile certificate services," adding, "We expect that the KB Mobile Certificate will enable even simpler and more convenient non-face-to-face transactions."
