Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an information processing apparatus having a secret function for controlling reading and writing of secretly registered data.

[0002]

2. Description of the Related Art Among data registered in an information processing apparatus, there are data that is desired to be kept secret, that is, data that should not be read from a storage unit unless a specific input operation or the like is performed. And data. Conventionally,
As an information processing apparatus with a secret function for controlling reading of registered data to be kept secret, for example,
No. 25364, an identification code indicating that the registered data is set to be confidential is added to specific registered data to be kept secret, and an input for releasing confidentiality of all registered data, for example, a password input is not performed. As long as the control based on the identification code is performed, only registration data that is not set as secret is read out. (Prior Art A) Thereby, the registration data set as secret is not read and the secret is maintained. In the related art, all registered data is confidentially collectively known. However, in this technique, it is necessary to input the password or the like every time the registered data is referenced or confidential. However, according to the prior art A, the password input or the like is performed only at the time of referencing the specific secretly set registration data, so that the operability is good and the chance of leaking the password or the like is reduced. Here, an example of the prior art A in the case where the registration data is schedule data will be described with reference to FIGS. FIG. 10 is a display example of one piece of schedule data in the secret release state, in which a title 51, date and time 52, contents 53 corresponding to the registered data, and an identification symbol 50 indicating that the secret is set are displayed. Have been. When this is displayed in a time table format, FIG.
As shown in FIG. 1 (a), a bar graph 52a corresponding to the title 51, the contents 53 and the date and time 52 is displayed. Do not show.

[0003]

However, in the example of the prior art A, there is a problem that the existence of the registered data itself becomes invisible and a schedule is erroneously made at the same date and time. . Further, not only the schedule data but also a problem that there is a problem that if there is little opportunity to release the confidentiality, even the input person forgets the existence of the registration data and cannot use the registration data sufficiently. As described above, the prior art A does not correspond to the need to always clearly indicate the existence of registered data that has been set secret. Accordingly, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide an information processing apparatus with a secret function for controlling readout of secretly set registration data. The content is kept secret, and the existence of the registration data itself can be specified to the user.

[0004]

In order to achieve the above object, the present invention provides a first storage means for storing a plurality of registration data, and has a relation with the registration data, and each of the registration data has a secret setting. An information processing apparatus with a secret function, comprising: second storage means for storing identification data indicating whether or not the registration data has been read; and reading means for controlling reading of the registration data based on the identification data. And third storage means for storing substitute data read by the read means in place of the registered data, wherein the read means replaces the read of the registered data based on the identification data. Thus, it is configured as an information processing apparatus with a secret function for reading the substitute data stored in the third storage means. Thus, the secret data is kept secret from the registered data, and the read substitute data is
The existence of the secretly set registration data can be clearly indicated.

The reading means reads the substitute data based on the identification data instead of reading the registration data, and performs a read control based on the identification data, which is a part of the registration data. It may be configured to also read out predetermined disclosure data that does not exist. This provides a system that is easy for a user to understand when a part of the secretly set registration data includes data to be read together with the substitute data. In addition, there is provided secret release input means for releasing the secrecy of the user from all of the registered data, and the reading means sets the identification information only when the secrecy is not released by the secret release input means. Instead of reading out the registered data based on data, a configuration may be considered in which the substitute data is read out. Accordingly, only the user who can release the security by, for example, inputting a password or the like can read the secret-registered registration data.

[0006] When receiving an instruction to delete the registration data, only when the confidentiality is not released by the confidentiality inputting means, whether to delete the registration data based on the identification data is determined. Or when receiving an instruction to update the registration data, and only when the secrecy has not been released by the secret release input means, the registration data is deleted based on the identification data. An apparatus provided with an updating unit for controlling whether or not to update is also conceivable. This prevents anyone other than the user who can release the confidentiality from deleting and updating the registered data with the confidentiality set, thereby maintaining security. Further, when each of the deletion means or the update means determines that the deletion or update is not performed, the first warning display means for displaying a warning indicating that deletion or update is not possible is provided. There may be. This is convenient because the user can know the reason why the registration data cannot be deleted or updated. Further, when the registration data is written under a condition that the writing of the secretly set registration data is possible only when the secret is released by the secret release input means, A second warning for determining whether or not the alternative data related to the data has been input, and displaying a warning that the alternative data has not been input if it is determined that the alternative data has not been input; When a warning is displayed by a device having a display means or further by the second warning display means,
It is also conceivable to provide a writing means for writing the registration data only when an input for permitting the writing of the registration data is made, and not performing the writing otherwise. Thereby, when registering the registration data in the secret setting, input omission of the substitute data is checked, so that erroneous registration can be prevented. Further, the apparatus may include a data display unit that outputs data including the registration data and the substitute data. It is also conceivable that the computer is configured as an information processing program with a secret function for causing a computer to function as the information processing apparatus with a secret function.
