Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention controls the output of confidential print data, which controls the output of print data sent from a host computer via a communication line to a printing means according to whether or not it has a confidentiality condition. Regarding the scheme.

[0002]

2. Description of the Related Art Since print data sent from a host computer to a printing device on a remote side is configured to be output without determining whether output is possible, important print data is also output. Although it has drawbacks, JP-A-60-157 proposed to eliminate such drawbacks.
In the publication No. 34, as shown in FIG. 6, a list name to be output and a password are input from the input device 52 and stored in the output list name storage unit 54 and the password storage unit 60. Then, prior to the output of the list, the output list name is transmitted from the processing device 56 to the printing device 51 and set in the output list designation register 57.

As a result, the contents of the output list name storage unit 54 are sequentially read out, and the output designating register 57 and the contents of the output list name storage unit 54 are compared by the comparison circuit 58.
The result is set in the comparison result display circuit 59. If they match, the password request report is transmitted to the processing device 56. Upon receiving this, the processing device 56 transmits the password corresponding to the output list to the printing device 51, sets this in the output list designation register 57, and then uses the comparison circuit 58 to compare the password read from the password storage unit 60. The comparison is made, and if they match, the data request report is transmitted to the processing device 56. The processing device 56 starts transmitting the output data to the printing device 51, and the AND gate 12
Is turned on and transmitted to the printing unit 13. In addition, reference numeral 6 in the drawing
Reference numeral 4 denotes a conversion circuit that converts the output data into different false data and outputs the output data even if the output data is erroneously or illegally transmitted by the processing device 56.

Since the confidential print data output method described above requires a password to be input at the time of printing, the confidential print data is not output if there is no operator who inputs the password on the remote side. However, there is a problem that the print data after that accumulates. Further, since the printout is performed on condition that the password is input by the operator, output of data other than confidential print data is limited, and even if it is attempted to output this, it is output as fake data by the conversion circuit and is output wastefully. Therefore, there is a problem that the utilization efficiency of the printer is reduced. Furthermore, since the password set for each print data is input, the number of passwords becomes enormous in proportion to the number of print data, and therefore the operator is burdened with managing the password for each user. Therefore, there is a problem in that a password input operation tends to make a mistake.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to manage confidential print data in accordance with confidentiality condition data set for each user, thereby making the password complicated. By eliminating the need for management and performing the output operation by inputting the user password data, the operator who performs the printing operation becomes unnecessary, while ensuring the confidentiality protection and the output of the print data without the confidentiality obligation. It is an object of the present invention to provide a confidential print data output protection method that enables the efficiency of use of a printing unit.

Further, an object of the present invention is to provide a confidential print data output protection system which allows a plurality of confidential print data sent to a specific user to be collectively printed out, thereby simplifying the printing operation. is there.

Note that the salary information of the user Sato is
Even if the print data name A is divided into the two, and both are input as the print data name A in the output attribute column, the print data name A can be input to the display input device and used as a batch print command. Further, as the personal identification data for each user, it is also possible to use the personal identification number instead of the user name and password as in the present embodiment. Furthermore, in this embodiment, the print data name and the form name are set and input as the confidentiality condition data, but the FCB name can also be set and input and used.

[0030]

As described above, according to the present invention, the output attribute of the transmitted print data is compared with the confidentiality condition data set for each user. When the personal identification data is input to the display input means by prohibiting registration to the user, the corresponding confidential print data in the first storage means is displayed and printed. Until then, the confidential print data is suppressed from being output and the confidentiality is surely secured. Moreover, it is possible to eliminate the need for an operator to output the confidential print data. Also, unlike the conventional method, a password is required for each print data. Since the confidentiality condition data is set for each user instead of setting the password, the password will increase in proportion to the increase in the number of confidential print data. This eliminates the need for complicated password management, and because the confidential print data name is displayed by the input operation to the display input means only by the user who receives the confidential print data, the confidential print data name is displayed. The unconditional disclosure of is surely prevented, and its confidentiality can be further improved.

Further, since the print data whose confidentiality condition data does not match the output attribute is configured to be output to the printing means immediately, the print data having no confidentiality obligation can be transmitted and output, and the print data of the printer can be output. It is possible to improve utilization efficiency.

Further, according to the present invention, the output attribute displayed on the display input means is input as a print command, and a plurality of confidential print data having a common output attribute among the confidential print data are collectively output. With this configuration, all the relevant confidential print data stored in the first storage unit can be output by the operation of inputting the output attribute, and the operability is improved.
