Next, the operation of the recording / reproducing apparatus will be described with reference to FIGS. 2 and 3. 2 and 3 show the recording / reproducing apparatus 1 of FIG.
12 is a schematic flowchart for explaining the operation of the 00.
Here, an operation in the case where Mr. A records a voice message to Mr. B in the recording / reproducing apparatus 100 and Mr. B performs one or both (playback and / or deletion) of the voice message, Will be explained. First, a procedure for registering the fingerprint and ID number of an operator who instructs reproduction or deletion of a voice message in the recording / reproducing apparatus 100 will be described with reference to FIG.
This will be described with reference to FIG.

First, in step S1, Mr. B inputs the ID number (first ID number) of Mr. B who plays or deletes a voice message to the operating means 10, and this operating means 10 A signal indicating the first ID number is supplied to the control means 6.

In step S2, Mr. B causes the fingerprint collation device 20 to read his / her own fingerprint. This fingerprint collation device 20 reads the fingerprint of Mr. B to generate first fingerprint data, and supplies the first fingerprint data of Mr. B to the control means 6. More specifically, in the fingerprint collation device 20, the fingerprint reading means 21 reads the fingerprint of Mr. B to generate first fingerprint data of analog data, and the A / D conversion means 22 converts the first fingerprint data into analog data. The data is converted into digital data.
Is supplied to the control means 6.

In step S 3, the control means 6 associates the first fingerprint data of Mr. B with the first ID number, and writes and stores these in the storage means 7 by the access means 3.

Next, the operation of the recording / reproducing apparatus 100 when reproducing or erasing a voice message will be described with reference to FIG. First, in step S11, Mr. A inputs the ID number (second ID number) of Mr. B, who is the operator who gives the reproduction or erasure instruction, to the operation means 10, and this operation means 10 A signal indicating the ID number 2 is supplied to the control means 6.

In step S12, Mr. A records the voice message in the recording / reproducing apparatus 100. Specifically, A
He inputs a voice message using the microphone 4. The microphone 4 converts a voice message into analog data. The A / D converter 5 converts the voice message from analog data to digital data and supplies it to the controller 6. The control means 6 associates the voice message of the digital data with the second ID number, and writes and stores these in the storage means 7 using the access means 3.

In step S13, at the time of reproducing or erasing the voice message, Mr. B receives collation by the fingerprint collation device 20, and it is determined whether or not he is the person himself. Specifically, fingerprint data (second fingerprint data) based on the fingerprint of Mr. B read by the fingerprint reading unit 21 and converted into digital data by the A / D conversion unit 22; Using the first fingerprint data associated with the ID number 1 and the first fingerprint data, the authentication unit 23 compares the two fingerprint data. The control means 6 determines whether the second ID number matches the first ID number,
If they match, the first fingerprint data associated with the first ID number is read from the storage unit 7 and supplied to the authentication unit 23.

If the authentication means 23 has generated a collation result indicating a match and was able to authenticate the identity of Mr. B, the control means 6 permits access to the input data in the storage means 7 and proceeds to step S14. . If the authentication unit 23 generates a collation result indicating a mismatch and fails to authenticate the identity of Mr. B, the control unit 6 suppresses access to the input data in the storage unit 7 and ends the processing of this flowchart. And does not reproduce or delete the audio data. As a result, reproduction and deletion of audio data by a person other than Mr. B can be suppressed.

In step S14, Mr. B issues an instruction as to whether the voice message is to be reproduced or deleted.
Enter 0. If an erasure instruction has been input to the operation means 10, the process proceeds to step S17. If a reproduction instruction has been input to the operation means 10, the process proceeds to step S15.

At step S15, the control means 6 reads out the voice message stored in the storage means 7 and which is associated with the second identification data by the access means 3, and reads this voice message into the D message. /
Output to A conversion means 8. The D / A converter 8 converts the voice message from the controller 6 into analog data and outputs the analog data to the speaker 9. The speaker 9 converts the analog data voice message into sound and reproduces and outputs the sound.

In step S16, Mr. B
The determination data indicating whether or not the storage of the voice message is necessary is input to the operation means 10, and the operation means 10 supplies the determination data to the control means 6. If the discrimination data indicating that the storage is required is input to the operation means 10, the voice message stored in the storage means 7 is not deleted, and the processing of this flowchart is ended. If the discrimination data indicating that the storage is not necessary is input to the operation means 10, the process proceeds to step S1.
Go to 7.

In step S17, the control means 6 accesses the voice message stored in the storage means 7 using the access means 3, deletes the voice message, and ends the processing of this flowchart.

As described above, by using the collation result to restrict access to the voice message, a voice message can be heard by a person other than B without the knowledge of Mr. It is possible to prevent the voice message from being erased and to protect the secret of the voice message stored in the storage means 7. If access control of a voice message is performed using the password of Mr. B, the password may be forgotten or stolen. However, since access control is performed using a fingerprint or the like, the information is unique to the human body. And plagiarism can be prevented.

The fingerprint reading means 2 of the fingerprint collating device 20
The case where a capacitance sensor is used as an example has been described as 1;
A fingerprint may be generated using analog data by photographing a fingerprint using a CD (Chage Coupled Device).
Although the case where the fingerprint collation device 20 is used as the collation means has been exemplified, the iris is read by the CCD to generate iris data,
An iris collation device that performs operator collation based on the iris data may be used. In addition, a voiceprint verification device that verifies an operator based on voiceprint data may be used as the verification unit. Also, a case has been described where Mr. A sends a message to Mr. B. However, Mr. A and Mr. B may be the same person, and the recording / reproducing apparatus 100 may be used as a diary to record a message for himself / herself. The storage means 7 may be configured to store encrypted fingerprint data.

The storage means 7 stores second collation data indicating that the collation result in the fingerprint collation device 20 (collation means) is inconsistent among the second fingerprint data (second collation data). It is good also as a structure which performs. In this way, when a person other than Mr. B attempts to reproduce or delete the voice message, the matching data of the person can be stored in the storage means 7, and the identification of the person can be performed. It becomes possible. The storage unit 7 stores count data indicating the number of generations of the second matching data together with second matching data indicating that the matching result indicates inconsistency.
When the same data as the collation data is generated again by the fingerprint collation device 20, the count data is counted up by the access means 3 and updated without storing the second collation data again. Alternatively, it may be possible to prevent the second collation data from being stored in the storage unit 7 redundantly.

Further, the control means 6 or the fingerprint collation device 20
Is a serial number of the second collation data indicating that the collation result in the fingerprint collation device 20 indicates a mismatch among the second collation data (however, the serial number is a value different from the ID number). If the same data as the second collation data indicating that the collation result indicates a mismatch is generated again by the fingerprint collation device 20, the storage unit 7 replaces the second collation data with the second collation data. The configuration may be such that the number assigned to the second comparison data is stored. By doing so, when the data size of the collation data is large, by storing the number having a smaller data size than the collation data, a person other than Mr. B can reproduce or delete the voice message more than once. In the case where the retry is performed, it is possible to prevent the data for matching of the person from being repeatedly stored in the storage unit 7 a plurality of times.

[0044]

According to the recording / reproducing apparatus and the driving method of the present invention, the access to the input data is suppressed when the collation result indicates mismatch, and the access to the input data is inhibited when the collation result indicates coincidence. Is permitted, it is possible to specify an operator who instructs reproduction or deletion of the input data using the collation. As described above, according to the present invention, it is possible to provide a recording / reproducing apparatus capable of specifying an operator who instructs reproduction or deletion of data such as a voice message stored in a storage unit, and a driving method thereof.
