Abstract

PROBLEM TO BE SOLVED: To hide the fact that a telephone call is made from a specified person in the past and to protect the privacy of the owner of a telephone set by not displaying the telephone number for caller information including the same telephone number as a specified telephone number specified beforehand. SOLUTION: When a caller data display key 8b is pressed, a control part 1 reads one item of caller data stored in the leading address of a caller data storage part 9a first. Then, non-display telephone numbers registered in a non- display telephone number storage part 9c are successively read and collated and whether or not the telephone number matched with the telephone number included in the caller data is registered in the storage part 9c is judged. Then, in the case that the matched telephone number is registered, the control part 1 replaces the telephone number and a name in the caller data with a specified character string and then, displays the caller data at a display part 7. Thus, the caller data including the number matched with the non-display telephone number registered in the storage part 9c are prevented from being displayed.

2. Description of the Related Art In some parts of the United States and Canada, a "caller telephone number transmission service" which is one of additional telephone services is implemented. According to this service, at the time of an incoming call or an incoming call from a third party during a call, identification information (caller information) about the caller is sent from the telephone exchange. Specifically, during the pause time of the first and second ring tones, caller data including a caller's telephone number, a name, a time at which a call was received, and the like are transmitted at a communication speed of 1200 bits per second. .

[0003] In Japan, Nippon Telegraph and Telephone Corporation has
The trial service was started in January 1997 for implementation in 1997. When such a service is started, by providing a memory or the like to the telephone, the transmitted caller information can be accumulated and recorded in the memory. Then, by sequentially displaying the stored caller information on the LCD or the like of the telephone according to the instruction of the operator, it is possible to know a list of persons who have called the telephone in the past.

[0004]

However, in the above-mentioned telephone, in order to display the caller information unconditionally, an unspecified number of persons use the telephone number or name of the caller stored in the telephone. There is a problem that the privacy of the owner of the telephone cannot be protected.

Accordingly, the present invention has been made in view of such a problem, and a telephone in which caller information stored in the telephone is not easily known to others, ie, a telephone for disclosing caller information. It is an object of the present invention to provide a telephone capable of protecting the privacy of its owner.

[0006]

In order to achieve the above-mentioned object, a telephone according to the present invention is a telephone corresponding to a caller telephone number transmission service, wherein the telephone of a caller transmitted via a telephone line is provided. Caller information storage means for acquiring and storing caller information including a telephone number, display means, display instruction input means for receiving an instruction to display caller information on the display means, and display instruction input means. When the instruction is received, the caller information stored in the caller information storage means is read out, and the judgment means for judging whether or not the telephone number included in the caller information matches a predetermined telephone number is determined. If not, the caller information is displayed on the display means, and if it is determined that they do not match, at least the telephone number of the caller information is not displayed on the display means. Characterized in that it comprises a display control means for controlling so.

[0007] Thus, by specifying the telephone number of the person who does not want to be seen by others as the specific telephone number, the telephone number can be prevented from being displayed on the display means. Its privacy is protected.

The control section 1 comprises a ROM in which a control program is stored, a RAM as a work area, a calendar timer, a microprocessor, and the like, and controls the entire telephone according to the control program. More specifically, in addition to the control provided by the control unit of a general telephone (such as outgoing / incoming control, hold control, calendar display control, etc.), the control specific to this telephone (registration control of a hidden telephone number described later, transmission Display control of user data).

Next, the operation of the telephone according to the present invention configured as described above will be described. FIG. 5 is a flowchart showing an operation procedure of the telephone. First, when the incoming call detector 2 detects a ringing tone from the telephone company exchange (step S1), the data demodulator 3 demodulates the caller data (step S2). The demodulated sender data is stored in the sender data storage unit 9a by the control unit 1 (step S3).

Thereafter, the hook control unit 4, the amplification unit 5, and the handset unit 6 start normal call processing. If there is an incoming call (call) from a third party during a call, the call processing (step S4) is bypassed. Such recording of the sender data is performed for each incoming call, and when the number of incoming calls exceeds 50, the latest 50 sender data is updated and recorded in the sender data storage unit 9a.

On the other hand, when there is no incoming call and a key input from the operation unit 8 is performed (steps S1 and S5), the control unit 1 determines the type of the input key (step S1).
6). As a result, when the non-display telephone number registration key 8c is pressed, the non-display telephone number is registered (step S6), and when the caller data display key 8b is pressed, the caller data storage section 9a. The display processing of the caller data stored in is performed (step S7), and the other 12 keys 8a
When is pressed, normal transmission processing is performed.

FIG. 6 is a flow chart showing a detailed procedure of step S6 (non-display telephone number registration processing) in FIG. When the non-display telephone number registration key 8c is pressed, the control unit 1 first obtains a 4-digit password from the operator through the 12 keys 8a (step S10). Then, the obtained security code is collated with the security code registered in the security code storage unit 9b in advance (step S11). As a result, if they do not match, the subsequent processing is stopped.

On the other hand, if the verification is successful, one non-display telephone number stored at the start address of the non-display telephone number storage section 9c is read out (step S13) and displayed on the display section 7 (step S13). ). Then, a new non-display telephone number is received from the operator through the numerical keys of the 12 key 8a, and the new non-display telephone number is overwritten and updated (registered / changed / deleted) in the non-display telephone number storage unit 9c.

When the update of one non-display telephone number is completed, the non-display telephone number stored at the next address is read out and the same processing is repeated (steps S12 to S14). Further, when the symbol key of the 12 key 8a is pressed, only the update display of the non-display telephone number is repeated, the personal identification number is updated, or the registration process is terminated according to the type of the key. (Step S15).

FIG. 7 is a flowchart showing the detailed procedure of step S7 (sender data display processing) in FIG. When the caller data display key 8b is pressed, the control unit 1
First, one piece of sender data stored at the start address of the sender data storage unit 9a is read (step S20).

Subsequently, the non-display telephone numbers registered in the non-display telephone number storage section 9c are sequentially read out and collated (step S21), so that a telephone number matching the telephone number included in the caller data is obtained. It is determined whether it is registered in the non-display telephone number storage unit 9c (Step S22).
As a result, when the matching telephone number is not registered, the control unit 1 displays the caller data on the display unit 7 as it is (step S24). The display result in this case is
For example, as shown in FIG.

On the other hand, if a matching telephone number is registered, the control unit 1 replaces the telephone number and name in the caller data with a specific character string ("****").
The sender data (only the specific character string and the arrival time) is displayed on the display unit 7 (step S23). The display result in this case is, for example, as shown in FIG. When the sender data display key 8b is pressed again, the controller 1 reads out the sender data stored in the next address of the sender data storage 9a and repeats the same processing (step S20). If the symbol key of the 12 key 8a is pressed, the display process is terminated (step S2).
5).

As described above, according to the present telephone, the caller data is stored in the caller data storage section 9a every time an incoming call is received, but matches the non-display phone number registered in the non-display phone number storage section 9c. This prevents caller data including the telephone number to be displayed from being displayed on the display unit 7. The non-display phone number registered in the non-display phone number storage unit 9c can be viewed or changed only by the owner of the personal identification number.

Thus, the owner of the telephone can hide the fact that the call was received from a specific person from others, thereby protecting the privacy of the telephone. In the above-described embodiment, the telephone number registered in the non-display telephone number registration key 8c is used as a target whose display on the display unit 7 is prohibited, but the control program of the control unit 1 may be additionally changed. Thereby, it can be used as a target for which return transmission is prohibited.

Here, "return call" refers to making a call from the present telephone to the caller associated with the caller data stored in the caller data storage section 9a. Specifically, the desired caller data is displayed on the display unit 7 and a key for returning the call is pressed, so that the on-hook call is made using the telephone number of the caller data displayed at that time. Is what you do.

FIG. 9 is a flowchart showing an operation procedure when the telephone makes a return call. Step S
30 to S34 are steps S20 to S2 shown in FIG.
Same as 4. The control unit 1 sets a variable flag indicating that the privacy protection process has been performed in step S33 to 1; otherwise, the variable flag
Is set to 0 (steps S35 and S36).

Subsequently, the control section 1 detects whether or not an instruction has been given by the operator using the symbol key of the 12 key 8a to make a return call (step S37). As a result, when the instruction is given, the current value of the variable flag is further determined (step S38), and the return transmission is performed only when the variable flag is not 1 (the privacy protection process is not performed) ( Step S39). That is, the control unit 1
Makes an on-hook call to the telephone number included in the caller data displayed on the display unit 7 at that time.

On the other hand, if there is no instruction to return the call, or if the variable flag is 1 even if the instruction is issued (the privacy protection process is being performed), the return call is not performed (steps S37 and S38). Then, the control section 1 sequentially repeats the display of the sender data and the return transmission until the termination instruction is received from the operator (step S4).
0).

Thus, the non-display telephone number registration key 8c
In addition to using the telephone number registered in the telephone number as a non-display target, the telephone number can be used as a target for which return calling is prohibited. As a result, the owner of the telephone can not only hide the fact that the telephone call from the specific person has been made to other people, but also prevent a situation in which another person executes the return call to the hidden specific person without permission.

The embodiment of the present invention has been described above.
It goes without saying that the present invention is not limited to such an embodiment. For example, in the above embodiment, it is prohibited to view or update the contents of the non-display telephone number storage unit 9c unless the password is verified, but the present invention requires such a form of protection function. It does not mean that.
A switch for permitting access to the non-display telephone number storage unit 9c may be provided on the bottom surface of the telephone, or no such protection function may be provided. This is because hiding the contents of the hidden telephone number storage unit 9c itself is not a direct object of the present invention.

In the above embodiment, the display of the caller data having the same telephone number is prohibited. However, instead of the telephone number, the name of the caller or the storage address of the caller data storage section 9a is used. You can also. Non-display phone number storage 9
This is because the data to be stored in c may be information that specifies one of the 50 cases stored in the sender data storage unit 9a.

Further, in the above embodiment, only the telephone number and the name of the caller in the caller data are replaced with specific characters and displayed. However, the present invention is not limited to this, and the caller data itself is displayed. It can be processed so as to be excluded from the target. Further, in the above-described embodiment, the sender data includes the sender's telephone number, name, and time at which the call was received. However, the present invention is not limited to such a data format. This is because the object of the present invention is to hide not only a telephone number and a name but also various kinds of caller information included in caller data, that is, identification information for specifying a caller.

[0035]

As is apparent from the above description, the telephone according to the present invention is a telephone corresponding to the caller telephone number transmission service, and is capable of storing the telephone number of the caller transmitted via the telephone line. Caller information storage means for acquiring and storing caller information including the information, display means, display instruction input means for receiving an instruction to display the caller information on the display means, and display instruction input means receiving the instruction. Determining means for reading the caller information stored in the caller information storage means and determining whether a telephone number included in the caller information matches a specific telephone number specified in advance; If so, the caller information is displayed on the display means, and if it is determined that they match, control is performed so that at least the telephone number of the caller information is not displayed on the display means. Characterized in that it comprises a that display control means.

[0036] With this, for the caller information including the same telephone number as the specific telephone number specified in advance, the telephone number is not displayed on the display means, so that the fact that a specific person has called in the past is considered. Can be hidden,
The privacy of the owner of the phone is protected. Here, the telephone further includes a transmission instruction input means for receiving an instruction to perform a return transmission based on the caller information stored in the caller information storage means, and a transmission when the transmission instruction input means receives the instruction. Means for reading the caller information from the caller information storage means, and judging whether or not the telephone number included in the caller information matches the specific telephone number specified in advance, and only when it is judged that they do not match. It is also possible to provide a return call control means for returning a call to a telephone number included in the caller information.

Thus, the owner of the telephone can not only prevent the specific caller information from being displayed, but also prevent another person from making a return call to the specific caller without permission. be able to. Therefore,
According to the present invention, a telephone which is compatible with the caller telephone number transmission service and which can easily protect the privacy of its owner is realized, and its practical effect is great.
