[action of first embodiment]
In the aforesaid structure, in the data handling system 1000 of present embodiment, for example, there is the data file F of verify data C to be registered in the computer installation 100, by 100 indications can make this data file of printing equipment 114 printouts F to computer installation with additional.
For example, read the data file F of hope at operator's manual operation computer installation 100, and under the situation of this data file of printout F, as shown in Figure 5, the printout (step S1) that the operator indicates the data file F that is read to computer installation 100.
Like this, computer installation 100 confirms whether added verify data C (step S2) among this data file F, not have under the situation of adding, and the data subject B of data file F is transformed to common print datas (step S8) such as bitmap.Because this print data is sent to printing equipment 114 (step S12) from computer installation 100, so shown in Fig. 4 (a), the data subject B of printing equipment 114 print output data file F.
On the other hand, added in data file F under the situation of verify data C (step S2), computer installation 100 shows input guiding (step S3) such as " the recognition data D that please import you " on display unit 112.
Therefore, if the manual operations of the operator who has confirmed the input guiding by keyboard 110 etc. are input to (step S4) in the computer installation 100 with the recognition data D of self, then computer installation 100 detects recognition data D from the verify data C of data file F, and contrasts the recognition data D of this data file F and the recognition data D that imported carries out authentication processing (step S6).
If it is consistent and suitable (step S7) to be judged as recognition data D by this authentication processing, then only the data subject B of data file F is transformed to print data (step S8), and sends to (step S12) the printing equipment 114 from I/F unit 113.
This printing equipment 114 since the print data printout that will be received to the printed medium of print paper etc., so shown in Fig. 4 (a), the data subject B of print output data file F on printed medium P only.
On the other hand, if be judged as recognition data D inconsistent and improper (step S7) by authentication processing, then data subject B and the result data R with data file F is transformed to print data (step S9, S10) respectively.Then owing to after synthetic these print datas (step S11), send to printing equipment 114 (step S12), so printing equipment 114 with the print data printout that received to printed mediums such as print paper.
In the computer installation 100 of the manner, owing to be set at result data R is synthesized on the data subject B as watermark, so shown in Fig. 4 (b), data subject B printed with the watermark of result data R output on the printed medium P.The watermark of this result data R is made of warning guiding as previously mentioned, and prints output with the state that can confirm the data subject B after synthetic.
In addition, the computer installation 100 of the manner does not all have input operation person's recognition data D (step S4, S5) through schedule time as if (step S3) after being presented on the display unit 112 in the input guiding with recognition data D, be improper with operator's automated validation then, still the data subject B of generated data file F and result data R make printing equipment 114 printouts (step S9～S12).
[effect of first embodiment]
In the data handling system 1000 of the manner, as mentioned above, the verify data C that utilizes data file F carries out authentication processing to the operator's that prints output data file F recognition data D, if the recognition data D after the authentication processing is suitable, the data subject B of print output data file F only then, but, then result data R is synthesized to printout on the data subject B, so can confirm that the operator of print output data file F is suitable or improper by print result if improper.
And because setting operation person's recognition data D is used as verify data C on data file F, so computer installation 100 does not need recognition data D is carried out data management, whether the person is suitable can to come the setting operation by each data file F.
Further, owing to also set result data R on the data file F,, also multiple result data R can be set among the data file F selectively corresponding to the content of data subject B so computer installation 100 does not need to keep result data R.
In addition, can be used as a spot of text data and wait and set recognition data D and result data R, so for recognition data D and result data R, the data capacity of data file F can not increase superfluously.
In addition, in the data handling system 1000 of the manner, as mentioned above,, then automatically perform the print processing of data subject B, so can not require the operator to carry out the input of recognition data D if in data file F, do not set verify data C with there is no need.
[variation of first embodiment]
The present invention is not limited to aforesaid way, allows to carry out in the scope that does not break away from its spirit various distortion.For example, in the aforesaid way example only print the situation of output on for the data subject B that result data is synthesized under the inappropriate situation of operator data file F in authentication, but can also be only to be authenticated to be under the suitable situation, result data R is synthesized to printout on the data subject B the operator.
At this moment, result data R for example is set at guiding such as " this document is printed by the wright " report etc., and preferably the upper and lower of printed medium P etc. is arrived in printout, so that it does not hinder data subject B.
Further, also can be suitable or improper corresponding to operator's authentication result, switch the first/the second result data R and print output.At this moment, shown in Fig. 3 (b), be preferably in the result data R that data file F goes up setting the first/the second, and print output selectively corresponding to authentication result.
In addition, in the aforesaid way example in data file F, be set with the situation of result data R, but also the result data R of typing can be registered in the computer installation 100.
Further, also can will be registered in the computer installation 100, will be set among the data file F corresponding to inappropriate second result data R corresponding to the first suitable result data R of authentication result.
In addition, the default result data R of registration on computer installation 100, and setting independently result data R among the data file F arbitrarily, and when in data file F, having set result data R, can select this result data R by computer installation 100, when not setting, can select default result data R.
Further, in aforesaid way, suppose in data file F a recognition data D is set at verify data C, but also a plurality of recognition data D can be set among the data file F as verify data C.
In addition, in aforesaid way, example in data file F directly setting operation person's recognition data D be used as verify data C, but also can set verify data C so that it can carry out authentication processing to recognition data D.
For example, a plurality of operators are being divided into a plurality of groups, and are organizing under the whether suitable situation of regulation printout, the recognition data of group is included among operator's the recognition data D and verify data C by each.
Further, in the aforesaid way example in data file F, registered the situation of verify data C, but for example also the corresponding relation of a plurality of recognition data D and a plurality of verify data C can be registered in the computer installation 100, utilize the corresponding relation of recognition data D that registers input to some extent and the verify data C that in data file F, adds to carry out authentication processing.At this moment, because verify data C can be the recognition data of data file F, so can cut down the capacity of data file F significantly.
In addition, in the aforesaid way, self the ID that supposes that the operator will be made of the text data of minority imports as recognition data D, but for example also can input ID and password is used as recognition data D.At this moment, by only with ID, or password only, or the combination of ID and password etc. is set at verify data C, also can carry out various authentication processing.
Further, in the aforesaid way, example the operator imported the situation of recognition data D by the manual operation of keyboard 110, but for example, also organism data such as operator's finger scan and sound input can be input in the computer installation 100 as recognition data D.At this moment, verify data C for example can be used as a plurality of characteristics of extracting out and waits and set from organism data.
In addition, in the aforesaid way, understand a series of actions of computer installation 100 specifically according to Fig. 5, but also can in the reconcilable scope of the order of this a series of actions, change described a series of actions.For example, example after carrying out authentication processing, data subject is transformed to the situation of print data, but carry out authentication processing after also data subject can being transformed to print data.
Further, in the aforesaid way only example utilize the verify data C of data file F to come operator's recognition data D is carried out the situation of authentication processing, but also can comprise so-called electronic signature or timestamp among this verify data C, the verify data C that can utilize data file F carries out authentication processing to operator's recognition data D, and utilizes verify data C that the legitimacy of data file F is carried out authentication processing.
In addition, in the aforesaid way, example by moving corresponding to the computer program of storage in RAM104 etc. by CPU101, each several part is logically realized the situation as the various functions of computer installation 100.But this each several part can form intrinsic hardware respectively, a part can be stored among RAM104 etc. as software, and a part is formed hardware.
