Abstract
Multimedia data having, embedded therein by using electronic watermark technique, data that includes first information to be disclosed, and second information for controlling the data to be disclosed is received by a data terminal via a communication network. The data terminal compares the second information included in the received multimedia data with the condition on the data terminal side. At least part of the multimedia data or first information is not displayed or is made illegible on the data terminal according to a result of the comparison of the second information. The multimedia data or the first information is displayed on the data terminal according to another result of the comparison of the second information.
Claims25
A data display method comprising the steps of:
- receiving, by a data terminal, multimedia data having embedded therein data that includes first information to be disclosed, and second information for controlling said data to be disclosed, said multimedia data symbolically representing a content of said embedded data;
- comparing said second information included in said received multimedia data with the condition on said data terminal side;
- and
- making at least part of said multimedia data or said first information invisible or illegible on said data terminal on the basis of a result of the comparison of said second information.
A data terminal comprising:
- a receiving portion for receiving multimedia data having embedded therein data that includes first information to be disclosed, and second information for controlling said data to be disclosed, said multimedia data symbolically representing a content of said embedded data;
- a processor for comparing said second information included in said received multimedia data with a condition on said data terminal side;
- and
- a display device capable of displaying said multimedia data and said first information, said processor making at least part of said multimedia data or said first information invisible or illegible on said data terminal on the basis of a result of the comparison of said second information.
A data display system comprising at least one client terminal having information wanted to disclose, at least one management server for managing multimedia data having such elements as to symbolize a content of said information, at least one WWW server for putting said multimedia data on view, and at least one client terminal for reading said multimedia data,
- said management server having means for embedding said desired-to-disclose information and a digital signature in said multimedia data when receiving a request from said client terminal having said desired-to-disclose information, and means for attaching a public key to said multimedia data and sending it to said WWW server,
- said WWW server having means for attaching said multimedia data to a Web page and sending said Web page with said multimedia data,
- said client terminal having means for acquiring from said management server said management server's public key and a program necessary for referring to said multimedia data, and storing them, means for acquiring said Web page with said multimedia data from said WWW server, means for comparing said public key attached to said multimedia data with said public key acquired from said management server and stored, means for making said multimedia data not displayed or said information embedded in said multimedia data not displayed if there is no coincidence in said comparison, and means for making said multimedia data displayed or said information embedded in said multimedia data displayed if they matches each other.
A data display system having at least one client terminal for reading information, said client terminal including means for embedding desired-to-read information and display conditions of said desired-to-read information in multimedia data having elements that symbolize said desired-to-read information, means for making said multimedia data not displayed or the content of said desired-to-read information not displayed if there is no coincidence about said display conditions, and means for making said multimedia data displayed or the content of said desired-to-read information displayed if there is a coincidence about said display conditions.
A data display system having at least one information distribution station for distributing information and at least one information processing terminal for reading the information embedded in multimedia data or said information after the processing of reliability confirmation of said multimedia data, wherein said station distributes said multimedia information, which has such elements as to symbolize a content of said information, reliability confirmation means and display control means, to said information processing terminal, and said information processing terminal displays said multimedia or said information embedded in said multimedia data.
A data display method comprising the steps of:
- displaying on a display device a Web page having set up therein link information to a mark manager side that manages a mark for authenticating said Web page together with said mark for certifying said Web page that said mark manager side apparatus manages;
- sending a request for confirming authenticity of said Web page to said mark manager side apparatus determined by said link information set up in said Web page when an operator selects said mark displayed together with said Web page on said display device;
- and
- controlling said mark to be controlled on the basis of display data included in said mark.
A recording medium having a program stored to be used in a data display system and that can be read by a computer, said program including the steps of:
- receiving, by a data terminal, multimedia data that has embedded therein data including first information to be disclosed, and second information for controlling said data to be displayed, said multimedia data symbolically expressing the content of said embedded data;
- comparing said second information included in said received multimedia data with the condition on said data terminal side;
- and
- making at least part of said multimedia data or said first information not displayed or illegible on said data terminal according to the result of said comparison of said second information.
