Ticket issuing method, ticket issuing system and ticket collating method

Claim 2

A ticket issuing method according to claim 1, wherein the step to make the security data includes the steps of: making binary embedded data by binary encoding basic security data comprising control code, letter, image, voice, etc.; and converting the binary embedded data into binary image data in preset specific format.

Claim 3

A ticket issuing method according to claim 1, wherein the step to make the ticket printing data includes the steps of: making prescribed pattern image data; making pattern modulated data by modulating the pattern image data by the security data; and superimposing the pattern modulated image data on the ticket image data.

Claim 4

A ticket issuing method according to claim 3, wherein the step of making the prescribed pattern image data includes the step of: arranging adjacent image data so that they become a combination of complementary colors.

Claim 5

A ticket issuing method according to claim 1, further comprising the step of: making ticket display data for checking the display by a display means of the user by partially reducing the ticket printing data; wherein the sending step sends the ticket display data together with the ticket printing data to a user via a communication means.

Claim 6

A ticket issuing method according to claim 5, wherein the step to make the ticket display data includes the steps of: executing the smoothing process of the ticket printing data; and executing the thinning process of the smoothing processed ticket printing data.

Claim 7

A ticket issuing method according to claim 1, wherein the ticket printing data making step includes the step of: embedding a part of the security data in the ticket image data in both the invisible state and the visible state.

Claim 8

A ticket issuing method according to claim 1, wherein the ticket printing data making step includes the step of: embedding a part of the security data in the ticket image data in both the invisible state and the visible state so that the invisible and visible state locations agree with each other.

Claim 9

A ticket issuing method according to claim 1, wherein the ticket printing data making step includes the step of: visibly adding a specific mark for distinguishing from the ticket image data without the security data embedded to the ticket image data with the security data embedded in the invisible state.

Claim 10

A ticket issuing method according to claim 1, wherein the security data is composed of user identification data, ticket issue date and time data, kind of ticket data, ticket available period data, ticket charge data and control data.

Claim 11

A ticket collating method comprising the steps of: making security data from ticket issue request data and user identification data sent from a user via a communication means; making ticket image data from the ticket issue request data; making a prescribed pattern image data; making pattern modulated image data by modulating the prescribed pattern image data by the security data; making ticket printing data by superimposing the pattern modulated image data on the ticket image data; sending the ticket printing data to the user via a communication means; restoring the security data from a ticket printed by the user based on the received ticket printing data; and judging genuineness of the printed ticket according to the restored security data.

Claim 12

A ticket collating method according to claim 11, wherein the restoring step includes the step of: making the security data visible by physically superimposing a sheet shape mask having the transmission factor of the same pattern as the pattern image data on the printed ticket.

Claim 13

A ticket collating method according to claim 11, wherein the restoring step includes the step of: reading the printed ticket data optically and comparing the obtained read signal with a mask signal representing the same pattern as the pattern image data, making the agreed portions of both signals invalid.

Claim 14

A ticket collating method according to claim 11, wherein the restoring step includes the step of: reading the printed ticket data optically and executing the thinning process of the obtained read signal at the period corresponding to spacial frequency of the pattern image data.

Claim 15

A ticket issuing system comprising: means for making security data from ticket issue request data and user identification data sent from a user via a communication means; means for making ticket image data from the ticket issue request data; means for making ticket printing data by embedding the security data in the ticket image data, the security data being invisible against the ticket image data when the ticket printing data including the ticket image data and the security data is printed on a ticket paper by the user; and means for sending the ticket printing data to the user via the communication means.

Claim 16

A ticket issuing method comprising the steps of: outputting security data according to ticket issue request data from a user via a communication means, the security data being visible when the security data is printed on a paper; outputting ticket image data from the ticket issue request data, the ticket image data being visible when the ticket image data is printed on a paper; outputting ticket printing data by embedding the security data in the ticket image data, the security data being invisible against the ticket image data when the ticket printing data including the ticket image data and the security data is printed on a ticket paper by the user; and sending the ticket printing data to the user via the communication means.
