CSC (Communication Service Concierge)NTT Cyber Solutions Laboratories

With the explosive increase in popularity of broadband and mobile network access in recent years, the connection of things

to the Internet that have never before been considered is beginning. We are also seeing rapid diversification in the ways

networks are employed by users. CSC is network middleware that serves as a platform for providing user-friendly services that

respond to the needs of this new network society.

In CSC, communication appliances that are connected to a network are configured with software components known as

plug-in modules. Network appliances include home gateways, automobiles, cell phones and other such devices that are

connected to a network. The required plug-in modules can be downloaded to the communication appliance from a data center to

immediately replace or add to existing plug-ins (1) when adding new services or devices, (2) when customizing functions for

individual customers, or (3) when it is desired to correct problems, download. CSC can be used in various fields, including home

automation, home security, ubiquitous services, mobile appliances, energy conservation, healthcare, telematics, and education.

CSC conforms to the industry standard OSGi* (www.osgi.org) specifications, with extended functions for better security and

providing safer services as well as functions for flexible cooperation among peer appliances. NTT promotes standardization

activities in the OSGi Alliance and established the OSGi Users’ Forum Japan (www.osgi-ufj.org) with other companies to

popularize this technology in Japan.

We will continue with future research and development to achieve even safer and faster provision of appealing network

services with CSC.

Music Discernment System via Mobile PhoneNTT Information Sharing Platform Laboratories

By a user transmitting a song heard on a street, from a radio or television to a data center via a mobile phone, this “music

discernment system via mobile phone” can identify the name of the song and inform the user of the name via e-mail.

In October 2004, in collaboration with NTT Resonant Inc., NTT Laboratories performed field test of the music discernment

system via mobile phone at “in the city Tokyo 2004”, a music industry event. After we had evaluated service requirements and

technical matters, the system was launched commercially in December 2004 as a mobile service provided by the Internet portal

site “goo”.

By combining “media research technologies” and “service integration technologies” developed at NTT Laboratories, this

system becomes a large-scale call-center system with outstanding customizability for mass-user services. Utilizing media-

search technology, it extracts characteristic data (i.e., a “fingerprint”) from a sound source sent from a mobile phone, checks a

previously prepared, huge database of fingerprints at high speed, and identifies the musical composition contained with the

sound source. Moreover, by utilizing service integration technology, mutual cooperation between multiple groups of

servers — such as CTI* servers and search servers for checking pairs of fingerprints — is possible. As a result of utilizing this

technology, a large-scale system can be constructed, while maintaining customizability, in a short time period from many

hundreds of systems. Maintenance such as database update adding new releases coming out day by day is available without

stopping the service.

From now onwards, we plan to apply the music discernment function to fields other than mobile phones, such as

broadcasting, we hope to expand the business domain of the NTT Group, such as copyright management business.

NTT-CERT, as the CSIRT for NTT GroupNTT Information Sharing Platform Laboratories

Information security cannot be pursued only by proactive protection measures. Moreover, since information systems mutually depend on

each other through multiple types of interactions over information network, it is difficult for an individual group, organization or person in charge

to execute effective security measures. With the aim of overcoming this difficulty, the activities of CSIRTs*1 and coordination among them have

been drawing much attention. The key factors for success of these activities are to construct and maintain capabilities for collecting incident

information and leading-edge trends commoditize know-how and delivery usable information in the right place at the right time.

The NTT Laboratories — R&D center to develop an information-security platform within the NTT Group — founded NTT-CERT*2 on October

2004 and started CSIRT activities since then. At the core of the NTT Group, NTT-CERT is a trusted contact point of NTT Group in regard to

information security and through which organizations and specialists inside and outside of the NTT Group can cooperate and receive reliable

back up regarding early incident detection, early incident resolution, limiting damages, and prevention. Put more concretely, NTT-CERT

analyzes security information collected from CSIRTs inside and outside of NTT Group, and develops advisories and technical documents in

the forms reusable at the scene of operation and delivers this information to appropriate place timely. On January 2005, NTT joined FIRST*3 or

Forum for Incident Response and Security Teams which is the worldwide CSIRTs alliance working on developing and coordinating member

CSIRTs all over the world in terms of exchanging security information and coordinated incident response worldwide, in order to tighten

relationship with other CSIRTs all over the world, since the security breaches and incidents nowadays can easily spread out worldwide.

From now onwards, NTT-CERT will develop a security management framework called “NTT CRISTs” for CSIRTs and the security

departments in NTT Group companies to share the security information and to manage incidents and their response. NTT-CERT will continue

to support establishing a CSIRT at NTT Group companies for their own, coordinating CSIRTs within NTT Group, and communicating with

other CSIRTS out of NTT Group.

Examples of how i-Visto is used

The i-Visto Internet HDTV Video Studio SystemNTT Network Service Systems Laboratories, NTT Network Innovation Laboratories

As evidenced by the beginning of terrestrial digital broadcasting in 2003, the transition in television broadcasting from analog

to digital format is being accompanied by a rapid shift toward multiple channels and higher image resolution. This trend has

presented broadcasters with the major problems of how to efficiently produce high definition television (HDTV) programs, which

require five times as much data as conventional standard definition television (SDTV) and distribute the programs to affiliated

stations across the nation.

NTT Laboratories have developed i-Visto*1 to provide an environment for producing and distributing high-quality HDTV

material at low cost to broadcasting industries. The i-Visto system functions as an integrated network system that implements,

for the first time, realtime transport, storage, and distribution of uncompressed multi-rate HDTV video up to 1.5 Gbit/s over an IP

network whose maximum speed is 10 Gbit/s.

Some research results and activities from 2004 are listed below.

(1) April 2004: Success in live, two-way uncompressed HDTV via a commercial 2.5-Gbit/s IP network between Japan and the U.S. at NAB*2 2004.

(2) August 2004: Success in live, uncompressed HDTV over a 10-Gbit/s IPv6*3 network between Osaka and Tokyo.

(3) November 2004: Successful transmission of up to six multiplexed uncompressed live HDTV signals using a video synchronization technique between Chiba, Tokyo, and Osaka over a 10-Gbit/s IP network at InterBEE*4 2004.

(4) February 2005: Remote conferencing with uncompressed HDTV video over a 10-Gbit/s IP network between Kanagawa and Osaka.

(5) March 2005: Successful uncompressed live HDTV transmission between the World’s Exposition site (in Aichi) and Osaka.

(6) March 2005: Successful development of a server system capable of storing and distributing uncompressed HDTV at up to 15 Gbit/s.

We will continue to expand this system with respect to network computing, including storage functions.

Container Administrative Experiment by Using Active RFID TagsNTT Network Innovation Laboratories

The NTT Laboratories are turning attention to Active RFID* as a key device for implementing distribution management and

automatic freight movement history recording. An Active RFID contains its own battery power supply for transmitting a radio

signal. Active RFID Tags that are already on the market emit weak signals periodically, but the NTT Laboratories have developed

a more powerful RFID that offers more advanced features.

We conducted verification experiments for marine shipping container management with the Active RFID. We attached our

400-MHz Active RFID to containers and measured the signal range. Even in a container yard where containers were stacked

around in the area, the signal could be read at about 30 m from the RFID. These results demonstrate the feasibility of recording

of freight movement histories in unprecedented detail by using this high-performance Active RFID on freight containers.

In future work, we will proceed with development and experimentation on highly accurate location determination technology

and various types of sensor network technology to achieve a more practical and efficient system.
