NTT Com and four other companies have developed two sets of web technologies under a three-year project of the National Institute of Information and Communications Technology. One technology will be used for a system that links websites prepared by separate entities and the other technology will ensure that linked websites operate securely. The new technologies will automatically generate a website linkage program by selecting appropriate program designs from among its database Users who have logged on to one of the websites will be able to move to another linked site without being asked for a password.
