Transfer apparatus, transfer network system and transfer method

Abstract

Disclosed are a transfer apparatus, a transfer network system and a transfer method. When data is disclosed to a plurality of users by using a transfer network and a transfer apparatus, data disclosure time control which cannot be adversely affected by the users is performed to reduce the difference in data disclosure time among the users. The transfer network system includes a distribution server (110) serving as a data-distribution-source transfer apparatus, and a network terminal (120) connected to distribution-destination user equipment (130). The distribution server (110) and the network terminal (120) each have a time keeping function and a time synchronization function for matching the time of the time keeping function with a master clock. The distribution server (110) sends in advance disclosure data and disclosure time to the network terminal (120). When the time of the time keeping function of the network terminal matches the disclosure time, the network terminal (120) sends the disclosure data to the user equipment (130).

Description

technical field [0001] The present invention relates to a transmission device, a transmission network system, and a transmission method, and particularly relates to a transmission device, a transmission network system, and a transmission method that have a function of simultaneously disclosing certain information to a plurality of users. Background technique [0002] In recent years, information transmission using a transmission network such as the Internet or a dedicated line has been widely used in the field of economic activities such as business transactions, and people are seeking to disclose news that may affect economic activities to users or use it for transactions. When important information such as the initial authentication key is used, fairness is improved by reducing the difference in information disclosure time for each user. [0003] Conventionally, there is a method of distributing information from the server all at once during a push service as a method aime...

Problems solved by technology

For Patent Document 2, although the time synchronization method between the server and the client is described, when the client receives information that includes the current time of the server, since the additional software on the client has a built-in timer and received In the way that the current time of the server is consistent, the time synchronization accuracy between clients is affected by the difference in the time required to transmit information from the server to each client

In addition, since the information disclosure control is performed by the software after the client receives the information, there is also a risk of eavesdropping on the information earlier than the set information disclosure time
