## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a system, a method and a program, which are utilized in mobile communication terminals such as mobile phone terminals, personal digital assistants (PDA) or the like, for storing and managing the user's personal information.
2. Description of the Related Art
Conventionally, a mobile phone terminal has a telephone book (or referred to as an address book) called a memory dial that stores personal information, and the data stored in the telephone book can be used to easily perform an operation for sending electronic mail (e-mail) or for making a call. The data stored in the telephone book, however, cannot commonly be transferred to other mobile phone terminals except for a part of the data such as telephone numbers. For this reason, for example, when another mobile phone terminal has to be used as an alternative device to deliver the mobile phone terminal of the user's own for repair, it has been impossible to transfer the data of such mail addresses, stored in the telephone book of the mobile phone terminal, to the alternative device and to use the transferred data in the alternative device.
When a mobile phone terminal is replaced with a terminal of another communication carrier, the data is rewritten in the telephone book in the renewed mobile phone terminal, or alternatively the data, which have been stored in the original telephone book, are copied to a PC (a personal computer) and then the copied data are moved to a telephone book of the renewed mobile phone terminal. This task, however, takes a lot of trouble.
In this connection, mobile phone terminals have been proposed which are configured such that all the personal information stored in a telephone book can also be used for another mobile phone terminal. For example, JP 2001-86220 (hereinafter, referred to as Patent Document 1) describes a mobile phone device provided with a removable personal-information storing means for storing personal information. In this mobile phone device, the telephone book's personal information is stored in the personal-information storing means that is installed in the mobile phone device. The personal information of a telephone book can be used in any mobile phone device by installing the personal-information storing means in the desired mobile phone device.
In addition to the above described Patent Document 1, JP2003-46634 (hereinafter, referred to as Patent Document 2) describes a mobile phone terminal provided with a SIM (Subscriber Identity Module) card. In the mobile phone terminal of this type, telephone-book data stored in a SIM card can be used as well in another mobile phone terminal.
Explanation next regards problems of conventional mobile phone terminals.
As described above, conventional mobile phone terminals have been inconvenient, because it has been impossible to use telephone-book data of a mobile phone terminal, as is, in an alternative device or a new mobile phone terminal. In addition, in copying telephone-book data to a PC or the like, it has been necessary to use a medium such as a data-link cable, memory card or the like, which was trouble some to set up. In addition, in conventional mobile phone terminals, there are other problems as described below.
In cases where a mobile phone terminal is lost or left behind somewhere, it is feared that personal information stored in the mobile phone may be illegally used by another person.
Furthermore, a memory storage capacity in a mobile phone terminal is predetermined for each device model, and a user who wishes to store many items of information in a telephone book has had to purchase high storage-capacity mobile phone terminals which are high priced. In addition, in cases where the user wishes to save information in excess of the maximum storage capacity of the mobile phone terminal, he or she has had to purchase an external memory card. Furthermore, a mobile phone terminal commonly has a storage capacity memory designed to store a predetermined number of items of the telephone-book data that are to be saved. Thus, a case may happen that this storage capacity provides superfluous memory for a user who handles only a small amount of the telephone-book information. Above described problems impose an excessive cost burden on the user.
While the mobile phone terminals described in Patent Documents 1 and 2 allow the telephone-book data to be utilized in other mobile phone terminals as well, these mobile phone terminals require memories for downloading telephone-book data into other mobile phone terminals, and this entails cost burdens for the user as described above. In addition, neither of these mobile phone terminals are capable of effecting operations such as transmitting e-mail via a PC or the like, based on the telephone-book data installed in the mobile phone terminal, while a telephone call is in progress using that terminal.
SUMMARY OF THE INVENTION
It is an object of the present invention to solve the above-described problems and provide a system and a method for storing and managing personal information capable of facilitating the utilization of the personal information such as telephone-book data in another mobile phone terminal or a PC and reducing the cost burden on the user.
It is another object of the present invention to provide a portable external memory system for storing and managing personal information.
It is a further object of the present invention to provide a program for implementing such a method of storing and managing personal information.
The principal feature of the present invention is a system having at least one mobile communication terminal carried by a user, and a portable external memory system carried by the user capable of making mutual communication with said mobile communication terminal through short-range wireless communication, wherein said portable external memory system stores in advance the user's personal information and also stores the registered authentication information for deciding validity of the mobile communication terminal in a first memory section; the mobile communication terminal transmits the information for authentication entered by the user for accessing the personal information to the portable external memory system; and the portable external memory system permits said mobile communication terminal to access user's personal information stored in the first memory section only when the information for authentication received from said mobile communication terminal coincides with said registered authentication information stored in said first memory section.
In the above-described construction, personal information such as telephone-book data is not stored in a mobile phone terminal, which is a mobile communication terminal, but is stored in the portable external memory system. Thus, it is possible to reduce the storage capacity of the mobile phone terminal by the amount of memory that is required for storing the personal information. For this reason, it is feasible for the user to buy a mobile phone terminal that has a small storage capacity regardless of whether the user needs a large or small amount of registered information in a telephone book.
In addition, since the mobile phone terminal stores no personal information, the user can protect the personal information from being used for illegitimate purposes even if the user has lost the mobile phone terminal or left it behind.
The user, when he or she has no mobile phone terminal at hand, can make a call request to access the personal information stored in the portable external memory system, as is, through the use of a mobile phone terminal borrowed from an acquaintance.
Also, in cases where the mobile phone terminal is renewed due to contract renewal or renewal of the device model or the like, it is feasible to utilize the personal information stored in the portable external memory system, as is, through the use of the renewed mobile phone terminal.
In cases where a mobile phone fails and an alternative device is provided, the user can access the personal information stored in the portable external memory system using the alternative device.
Another feature of the present invention is in the construction that, when the user effects a predetermined input operation, the portable external memory system requests an input of the information for authentication necessary for access to the personal information, to the user, and reads out the personal information from the first memory section, only if the information for authentication entered by the user in response to the request coincides with the registered authentication information that is stored in the first memory section, and displays the read personal information. Since this construction allows displaying the personal information on the portable external memory system itself, the user can acquire necessary personal information using the portable external memory system even if the user has left his or her mobile phone terminal in his or her home.
A further feature of the present invention resides in the construction that, the mobile phone terminal stores the information for authentication that is entered by the user in the second memory section, and when an input operation for a telephone call request or transmission of an electronic mail is effected by the user, it transmits the information for authentication stored in the second memory section to the portable external memory system, following which the mobile phone terminal acquires from the portable external memory system the personal information necessary for the call request of the telephone or the transmission of the electronic mail and displays the acquired personal information. This construction allows automatic display of the personal information when a telephone call request and electronic mail transmission are performed.
Still a further feature of the present invention is in the construction that the mobile phone terminal, at the time of receiving a telephone call or the receipt of electronic mail, transmits the information for authentication, stored in the second memory section, to the portable external memory system; acquires the personal information on the caller of the arrived telephone call or the transmitter of the received electronic mail from the portable external memory system; and displays the acquired personal information. This construction allows the automatic display of personal information regarding the telephone caller and sender of electronic mail.
Still a further feature of the present invention is in the construction that the portable external memory system permits access to the personal information stored in said first memory section for at least two mobile communication terminals at once, each of which has the information for authentication that coincides with the contents of the registered authentication information. This construction allows the user to make a telephone call request with reference to personal information stored in the portable external memory system using a mobile communication terminal, while simultaneously making a mail communication using another mobile communication terminal (for example, a PC) with reference to personal information stored in the portable external memory system.
A further feature of the present invention is in the construction that a system device capable of effecting mutual communication with the portable external memory system through a short-range wireless communication, requests that the user input information for authentication necessary for access to the personal information when a predetermined input operation has been effected by the user and transmits the information for authentication, entered by the user in response to the request, to the portable external memory system; and the portable external memory system permits the system device to access the personal information stored in the first memory section only if the information for authentication received from the system device coincides with the registered authentication information stored in the first memory section. In this case, the system device can be configured to acquire, from the portable external memory system, destination information necessary for a telephone call request or transmission of electronic mail through a communication terminal connected to a predetermined communication network and to display the acquired information. This construction allows a telephone call request and electronic mail transmission at the system device with reference to the personal information stored in the portable external memory system.
The above and other objects, features and advantages of the present invention will become apparent from the following description with reference to the accompanying drawings, which illustrate examples of the present invention.

(1) Establishment and Cancellation of Authentication
On those occasions when the user intends to employ wristwatch 20 as an external memory device, the establishment of authentication is conducted by mobile phone terminal 10a. When the establishment of authentication is intended, the user first performs an input operation at input section 13. This input operation causes control section 15 to read the program for executing the establishment of authentication, stored in advance in memory section 12, and to execute the program. Execution of the program involves a procedure by control section 15 that requires the user to input his/her PIN (personal identification number) through display section 14. Once the user inputs the PIN number, control section 15 operates to transmit the received PIN and also the ID number, assigned in advance to the mobile phone terminal to which control section 15 belongs, from wireless section 11 to wristwatch 20 as registered authentication information. The ID number is assigned when the communication carrier, who provides the mobile phone terminal, makes the utilization contract with the user.
In wristwatch 20, the registered authentication information (the PIN and ID numbers) that is transmitted from mobile phone terminal 10a is received by wireless section 21. Control section 24 operates to store the registered authentication information that is received in wireless section 21 into memory section 22. In the later steps, control section 24 decides access validity from mobile phone terminal 10a on the basis of the registered authentication information that is stored in memory section 22.
When canceling the establishment of the authentication, the user performs an input operation at input section 13 of mobile phone terminal 10a. In response to this input operation, control section 15 reads the program for canceling establishment of authentication, stored in advance in memory section 12, and executes the program. Execution of the program involves a procedure by control section 15 that requires the user to input his/her PIN number through display section 14. Upon the user inputs the PIN number at input section 13 in response to the requirement, control section 15 operates to transmit the received PIN and also the ID number assigned to the mobile phone terminal to which control section 15 belongs, from wireless section 11 to wristwatch 20 as registered authentication information. In wristwatch 20, control section 24 collates the information for authentication (the PIN and ID numbers) that is received at wireless section 21 with the registered authentication information stored in memory section 22.
If the collation results do not match, then control section 24 operates to send a notification from wireless section 21 to mobile phone terminal 10a that the authentication processing has not been normally completed. In mobile phone terminal 10a, when receiving notification that the authentication processing has not been normally completed, control section 15 operates to display a message on display section 14 describing the subject matter of the notification and ends the processing for canceling the establishment of authentication.
If the collation results match, then control section 24 operates to erase the registered authentication information stored in memory section 22 with regard to mobile phone terminal 10a, and also sends notification from wireless section 21 to mobile phone terminal 10a that the cancellation of the establishment of authentication has been normally completed.

When the user makes an input operation for transmitting/receiving e-mail at input section 32 of system device 30, control section 34 executes the program for e-mail stored in advance in a memory section (not shown). Execution of the program causes control section 34 that requires the user to input a PIN number through display section 33 in order to execute the authentication processing and also to operate to send the PIN, entered by the user in response to this requirement, from wireless section 31 to wristwatch 20. Since the authentication processing is as explained in the above section “(5) Making telephone calls through use of a communication terminal 40”, the explanation thereof is herein omitted.
The state in which access to wristwatch 20 is attained after the authentication processing. In system device 30, control section 34 operates to acquire from wristwatch section 20 information required by the user in the personal information that is stored in memory section 22, for example, information on destination of e-mail, and to display the acquired information on display section 33, whereby the user can effect a transmission operation of the mail through communication terminal 40 at input section 32 with reference to the personal information displayed on display section 33. In addition, on receiving e-mail, control section 34 operates to acquire the information on the transmitter from wristwatch 20 and also to display the acquired information on display section 33. In this way, the user can obtain information on the transmitter relevant to e-mail that is received through communication terminal 40, whereby processing at the time of transmission and receipt of e-mail through the utilization of communication terminal 40 is effected by making use of the telephone-book data.
Furthermore, in order to transmit and receive e-mail through the utilization of communication terminal 40, it is necessary for the user to install in advance in system device 30 information necessary for the transmission and receipt of e-mail (mail addresses, name of the mail server and the like given in advance). Still further, it is feasible to employ an existing procedure for settling accounts as a means to levy a utilization charge for communication terminal 40 (a charge for communication), for example, the settlement of accounts through the use of a credit card, which the user carries with him or her, or the settlement of accounts through the use of a medium such as an IC card that allows account transaction, or the like.
(7) Display of Personal Information in Stand-Alone Wristwatch 20
When the user makes an input operation for displaying personal information at input section (not shown) of wristwatch 20, control section 24 executes the program for displaying the personal information stored in memory section 22. Execution of the program involves the procedure by control section 24 to require the user to input a PIN number through display section 23. When the user inputs the PIN number in response to the requirement at the input section, control section 24 collates the received PIN with the registered authentication information (the PIN) stored in memory section 22.
If the collation results do not match, then control section 24 operates to display a message that the authentication processing has not been normally completed at display section 23 and ends the process to display personal information. If the collation results match, then control section 24 operates to display a message that the authentication processing has been normally completed at display section 23 and also to display the personal information that is stored in memory section 22.
In the above-described system for storing and managing personal information of the present embodiment, personal information such as telephone-book data (data x) is not stored in a mobile phone terminal but is stored in wristwatch 20. Thus, it is possible to reduce the storage capacity of the mobile phone terminal by the amount that would be required to store data x.
In addition, since personal information (data x) is not stored in the mobile phone terminal, use of the personal information for illegitimate or unauthorized purposes can be obviated even if the user has lost the mobile phone terminal or has left it behind.
Also in cases where the user has left his or her mobile phone terminal at home, the user can effect a telephone call request, transmission and receipt of e-mail by accessing to personal information (data x), for example, at system device 30, provided that the user carries wristwatch 20.
Furthermore, since it is feasible to display the personal information (data x) on wristwatch 20 itself, the user can obtain the necessary information from the displayed personal information.
In cases where, due to failure of the mobile phone terminal, an alternative device is provided, the user can obtain the personal information from wristwatch 20 by using the alternative device. In this case, the user first effects an establishment of authentication on wristwatch 20. The procedures of the establishment of authentication are as in the above-described paragraph “(1) establishment and cancellation of authentication.” By establishment of authentication, access of the alternative device to wristwatch 20 becomes feasible, whereby the user can send and receive telephone calls and also transmission and receipt of e-mail through utilization of the personal information stored in wristwatch 20 by using an alternative device as well. In the same way, the user, when he or she has no mobile phone terminal at hand, can make a call request by utilizing the personal information stored in wristwatch 20 as is, through the use of a mobile phone terminal borrowed from an acquaintance. Also, in cases where the mobile phone terminal is renewed due to contract renewal or renewal of the device model or the like, it is feasible to utilize the personal information stored in wristwatch 20 as is, through the use of the renewed mobile phone terminal.
In mobile phone terminal 10b is used as a PC that is provided with a capability both for short-range wireless communication with wristwatch 20 and for connecting with the internet, the user can make a telephone call request by mobile phone terminal 10a with reference to the personal information stored in wristwatch 20 and also can transmit and receive e-mail at the same time based on the personal information stored in wristwatch 20 by making use of the PC.
The hereinabove described system for storing and managing personal information of the present embodiment is an example and the construction can properly be modified within a general range without departing from the spirit of the present invention. For example, while the above embodiment employs a wristwatch as an external memory device, the memory device can be a commodity that the user daily carries, such as a key-holder, a music player, a radio, a writing utensil, a credit card, a commuter ticket or a purse, in place of wristwatch 20.
Furthermore, while the explanation has used a mobile phone terminal as an example, other portable communication terminal such as a PDA or a PC may be used in place of the mobile phone terminal.
Further, while a PIN number is used as authentication information, any of a variety of other information items may be used such as a pass word or the like.
Additionally, wristwatch 20 is as item purchased by a user the storage capacity of which can be determined depending on the amount of data required by the user.
The sections, mobile phone terminals 10a and 10b, wristwatch 20 and system device 30, are adapted to perform the respective operations basically through execution of a program by a computer, the operations being: “(1) Establishment and cancellation of authentication”; “(2) Registration and editing of personal information into wristwatch 20 by the user”; “(3) Receiving and sending telephone calls through the use of mobile phone terminal 10a”; “(4) Transmission and receipt of e-mail through the use of mobile phone terminal 10a”; “(5) Making telephone calls through the use of communication terminal 40”; “(6) Transmission and receipt of e-mail through the use of communication terminal 40”; and “(7) Display of personal information in stand-alone wristwatch 20.”
As described above, the present invention allows a mobile phone terminal borrowed from an acquaintance, an alternative device, a mobile phone terminal newly purchased due to a new contract, a change in the device model or the like, and a PC, to utilize the personal information (the telephone-book data and the like) stored in a portable external memory system as is without any transfer of the data, thereby improving user-friendliness.
Furthermore, since it suffices for the user to buy a mobile phone terminal that has a small storage capacity regardless of the amount of telephone-book data to be used, the cost burden to the user can be alleviated.
In addition, since the mobile phone terminal stores no personal information, this information is protected from being used for illegitimate or unauthorized purposes even when the user has lost the mobile phone terminal or left it behind.
Further, since it is feasible for the user to make a phone call while using the terminal as a PC to send/receive e-mail, user friendliness of the present invention is further improved.
While preferred embodiments of the present invention have been described using specific terms, such description is for illustrative purposes only, and it is to be understood that changes and variations may be made without departing from the spirit or scope of the following claims.
