SoftBank and TBCASoft Launch Blockchain-Based “Identification & Authentication” Working Group under the Carrier Blockchain Study Group (CBSG)

SUNNYVALE, Calif. & TOKYO–(BUSINESS WIRE)–SoftBank Corp. (“SoftBank”) (TOKYO: 9434) and TBCASoft,
Inc. (“TBCASoft”)
today announced the launch of a blockchain-based
“Identification & Authentication” Working Group under the Carrier
Blockchain Study Group (CBSG), the global blockchain consortium of
telecom carriers. TBCASoft created a new foundation application
framework called Cross-Carrier Identification System (CCIS)
that will focus on enabling identification and authentication services.
SoftBank and TBCASoft are leading this Working Group under the CBSG
Consortium and will collaborate with CBSG Consortium members around the
world.

Most current identification systems rely on a centralized database that
could be dominated by a minority group. Users of those services need to
trust one centralized authority to provide accurate identification and
authentication processes. As a result, individuals disclose personal
information to the system providers on numerous internet databases.
Compared to centralized services, CCIS provides a blockchain-based
solution operated by independent CBSG carrier members under a CCIS
Cross-Carrier Consensus with carrier-grade reliability. CCIS uses Zero
Knowledge Proof cryptography and Distributed Ledger Technology (DLT)
that enables issuing, storing and authenticating a user’s identification
without having to reveal private detailed information that the user may
not want or need to share.

CCIS gives individuals freedom from creating multiple accounts and
remembering countless passwords to protect their personal information
from identity thefts by using TBCASoft’s Cross-Carrier Blockchain
Technology and telecom carriers’ highly protected data centers. Via
CCIS, businesses and individuals can share and verify encrypted digital
identities without disclosing confidential or private information.

Takeshi Fukuizumi, VP of SoftBank, said, “We envision that individuals
should create encrypted digital identities, instead of using and storing
multiple usernames and passwords on databases here and there with
various qualities of privacy protection. We have been working with
TBCASoft on solving identification and authentication problems, and have
an answer with CCIS. We believe that telecom operators under the CBSG
Consortium will play very important roles in the global identity
business.”

Ling Wu, Founder and CEO of TBCASoft, said, “After the success of the
Cross-Carrier-Payment System (CCPS), CCIS is another important
foundation application framework that TBCASoft has been developing for
CBSG Consortium members. CCIS is a global platform that protects
individuals’ identities from fraudulent activities with telecom
carrier-grade reliability. TBCASoft is committed to working with telecom
carriers to provide comprehensive and cost-effective blockchain-based
identification and transaction services to businesses and individuals
around the globe.” Mr. Wu is also the Co-Chairman of the CBSG Consortium.
