Electronic writing implement and method of electronic writing

An electronic writing implement that outputs electronic information, comprising:

• a writing means that writes characters or symbols on a medium, said characters or symbols corresponding to a writing movement of a user of said electronic writing implement on said medium, the characters or symbols producing an imprint on said medium;
• and
• a sending means for ending electronic certification information that identifies said electronic writing means, in accordance with said writing by said writing means;
• wherein said medium stores said electronic certification information into a storing means, contained in an Integrated Circuit (IC) embedded in said medium, associating said electronic certification information with said medium.

A method of giving approval to information held in a medium, by using a seal stamp that can transfer a seal image of a stamp surface to said medium, wherein, according as a user of said seal stamp makes a sealing movement on said medium, the following steps are carried out, said steps comprising:

• transferring said seal image to said medium, the seal image producing an imprint on said medium;
• sending electronic certification information that identifies said seal stamp to a storing means, contained in an Integrated Circuit (IC) embedded in said medium, associating said electronic certification information with said medium;
• and
• storing the sent electronic certification information into said storing means;
• wherein authenticity of the approval of the information held in said medium can be confirmed using the stored electronic certification information and the transferred seal image.

An electronic writing implement that outputs electronic information, comprising:

• a pen unit, the pen unit being provided at a tip of said electronic writing implement and writes characters or symbols on a medium, said characters or symbols corresponding to a writing movement of a user of said electronic writing implement on said medium, the characters or symbols producing an imprint on said medium;
• memory, the memory being contained in an Integrated Circuit (IC) embedded in said medium and storing electronic certification information for identifying said electronic writing implement;
• and
• a transmitter, the transmitter electrically connected with said memory, the transmitter sending said electronic certification information in accordance with the writing by said pen unit.

A certification system comprising:

• an electronic seal, the electronic seal capable of writing characters or symbols;
• an electronic sheet, the electronic sheet allowing the writing of characters or symbols onto it by the electronic seal, said characters or symbols corresponding to a writing movement of a user of the electronic seal on the electronic sheet, the characters or symbols producing an imprint on the electronic sheet, the electronic sheet containing an embedded Integrated Circuit (IC) with memory, the memory storing electronic certification information identifying said electronic seal and associating said electronic certification information with said electronic sheet;
• and
• a transmitter, the transmitter electrically connected with said memory and sending the electronic certification information to said memory in accordance with said writing.

A certification method comprising:

• writing characters or symbols by an electronic seal onto an electronic sheet, the characters or symbols producing an imprint on the electronic sheet;
• storing electronic certification information identifying said electronic seal and associating said electronic certification information with said electronic sheet in a memory, the electronic sheet containing an embedded Integrated Circuit (IC) containing the memory;
• and
• sending the electronic certification information to said memory in accordance with said writing.
