Abstract

Provided are a method and apparatus for managing a graded cipher. The method includes that: a corresponding relationship between different security grades and corresponding voice passwords is established, herein the voice password corresponding to each security grade in the corresponding relationship is a part or all of a preset voice password; and a voice password is received from a user, and the obtained corresponding relationship is searched for the security grade corresponding to the voice password matched with the received voice password.

Claims

1. A method for managing a graded cipher, comprising:

establishing a corresponding relationship between different security grades and corresponding voice passwords, wherein a voice password corresponding to each security grade in the corresponding relationship is a part or all of a preset voice password; and

receiving a voice password from a user, and searching the obtained corresponding relationship for a security grade corresponding to a voice password matched with the received voice password.

2. The method according to claim 1, wherein when a security grade in the corresponding relationship is higher, a length of a voice password corresponding to the security grade is larger.

3. The method according to claim 1, wherein the establishing a corresponding relationship between different security grades and corresponding voice passwords comprises:

acquiring the preset voice password and a security grade number in advance; and

acquiring a voice password, of which a length is (N-i)/N of a length of the preset voice password, from the preset voice password, and setting a corresponding relationship between the obtained voice password and an ith security grade;

wherein N is the security grade number, and i is an integer more than or equal to 0.

4. The method according to claim 3, wherein the setting a corresponding relationship between the obtained voice password and an ith security grade comprises:

extracting a voiceprint characteristic of the obtained voice password, and storing a corresponding relationship between the voiceprint characteristic of the obtained voice password and the ith security grade;

the searching the obtained corresponding relationship for a security grade corresponding to a voice password matched with the received voice password comprises;

acquiring a voiceprint characteristic of the received voice password; and

searching the obtained corresponding relationship for the security grade corresponding to a voiceprint characteristic of the voice password matched with the voiceprint characteristic of the received voice password.

8. A computer-readable storage medium, storing a computer-executable instruction, the computer-executable instruction being used to execute the method according to claim 1.

9. The method according to claim 2, wherein the establishing a corresponding relationship between different security grades and corresponding voice passwords comprises:

acquiring the preset voice password and a security grade number in advance; and

acquiring a voice password, of which a length is (N-i)/N of a length of the preset voice password, from the preset voice password, and setting a corresponding relationship between the obtained voice password and an ith security grade;

wherein N is the security grade number, and i is an integer more than or equal to 0.

10. A computer-readable storage medium, storing a computer-executable instruction, the computer-executable instruction being used to execute the method according to claim 2.

11. A computer-readable storage medium, storing a computer-executable instruction, the computer-executable instruction being used to execute the method according to claim 3.

12. A computer-readable storage medium, storing a computer-executable instruction, the computer-executable instruction being used to execute the method according to claim 4.

5. An apparatus for managing a graded cipher, comprising:

an acquisition module, configured to establish a corresponding relationship between different security grades and corresponding voice passwords, wherein a voice password corresponding to each security grade in the corresponding relationship is a part or all of a preset voice password;

a receiving module, configured to receive a voice password from a user; and

a searching module, configured to search the obtained corresponding relationship for a security grade corresponding to a voice password matched with the received voice password.

6. The apparatus according to claim 5, wherein the acquisition module is configured to,

acquire the preset voice password and a security grade number in advance;

and

acquire a voice password, of which a length is (N-i)/N of a length of the preset voice password, from the preset voice password, and set a corresponding relationship between the obtained voice password and an ith security grade;

wherein N is the security grade number, and i is an integer more than or equal to 0.

7. The apparatus according to claim 5, wherein the acquisition module is configured to,

acquire the preset voice password and a security grade number in advance;

and

acquire a voice password, of which a length is (N-i)/N of a length of the preset voice password, from the preset voice password, extract a voiceprint characteristic of the obtained voice password, and store a corresponding relationship between the voiceprint characteristic of the obtained voice password and an ith security grade;

wherein N is the security grade number, and i is an integer more than or equal to 0; and

the searching module is configured to,

acquire a voiceprint characteristic of the received third voice password, search the obtained corresponding relationship for the security grade corresponding to a voiceprint characteristic of the voice password matched with the voiceprint characteristic of the received voice password, and enter the searched security grade.
