Abstract

A user data management apparatus for connection to a terminal data processor used by a user through a network, registers data that is dependent on a user ID peculiar to the user. The user data management apparatus has a first unit for generating a first data registration screen, when data of the user is to be initially registered, which differs from user ID to user ID, and a second unit for displaying, on the terminal data processor, a second data registration screen based on the first data registration screen generated by the first means, when the data of the user is to be registered.

Claims

1. A user data management apparatus for being connection to a terminal data processor used by a user through a network, for registering data dependent on a user ID peculiar to the user, comprising:

when data of said user is to be initially registered, first means for generating a first data registration screen, which differs from user ID to user ID; and

when the data of said user is to be registered, second means for displaying, on said terminal data processor, a second data registration screen based on said first data registration screen generated by said first means.

2. The user data management apparatus according to claim 1, wherein said first means hashes a character string obtained from any one of a plurality of elements making up said user ID with respect to a constant assigned to a predetermined picture, thereby producing message digest character strings, produces relocating identifiers peculiar to the user by sequentially sorting the message digest character strings, masks a predetermined range of the relocating identifiers from the beginning thereof, and generates said first data registration screen from the relocating identifiers outside of said predetermined range;

and

said second means dehashes said first data registration screen generated by said first means to produce the constant assigned to said predetermined picture, hashes a character string obtained from any element amongst those elements making up said user ID which are other than the element used to generate said first data registration screen, thereby producing message digest character strings, sequentially sorts the message digest character strings, extracts the position of said constant therein, and extracts identifiers required to form an image at the position, thereby generating said second data registration screen.

3. The user data management apparatus according to claim 1, wherein said second means performs a one-time session to display said second data registration screen on said terminal data processor.

4. The user data management apparatus according to claim 2, wherein said second means performs a one-time session to display said second data registration screen on said terminal data processor.

5. A method of managing user data on a user data management apparatus for connection to a terminal data processor used by a user through a network, for registering data dependent on a user ID peculiar to the user, comprising the steps of:

when data of said user is initially to be registered, generating a first data registration screen, which differs from user ID to user ID; and

when the data of said user is to be registered, displaying, on said terminal data processor, a second data registration screen based on said first data registration screen generated by said first-mentioned step.

6. The method according to claim 5, wherein said first-mentioned step comprises the steps of hashing a character string obtained from any one of a plurality of elements making up said user ID with respect to a constant assigned to a predetermined picture, thereby producing message digest character strings, producing relocating identifiers peculiar to the user by sequentially sorting the message digest character strings, masking a predetermined range of the relocating identifiers from the beginning thereof, and generating said first data registration screen from the relocating identifiers outside of said predetermined range;

and

said second-mentioned step comprises the steps of dehashing said first data registration screen generated by said first means to produce the constant assigned to said predetermined picture, hashing a character string obtained from any element amongst those elements making up said user ID which are other than the element used to generate said first data registration screen, thereby producing message digest character strings, sequentially sorting the message digest character strings, extracting the position of said constant therein, and extracting identifiers required to form an image at the position, thereby generating said second data registration screen.

7. The method according to claim 5, wherein said second-mentioned step comprises the step of performing a one-time session to display said second data registration screen on said terminal data processor.

8. The method according to claim 6, wherein said second-mentioned step comprises the step of performing a one-time session to display said second data registration screen on said terminal data processor.

9. The user data registration apparatus for registering data dependent on a user ID peculiar to a user, comprising:

a display unit;

when data of said user is to be initially registered, first means for generating a first data registration screen, which differs from user ID to user ID; and

when the data of said user is to be registered, second means for displaying, on said display unit, a second data registration screen based on said first data registration screen generated by said first means.

10. The user data registration apparatus according to claim 9, wherein said first means hashes a character string obtained from any one of a plurality of elements making up said user ID with respect to a constant assigned to a predetermined picture, thereby producing message digest character strings, produces relocating identifiers peculiar to the user by sequentially sorting the message digest character strings, masks a predetermined range of the relocating identifiers from the beginning thereof, and generates said first data registration screen from the relocating identifiers outside of said predetermined range;

and

said second means dehashes said first data registration screen generated by said first means to produce the constant assigned to said predetermined picture, hashes a character string obtained from any element amongst those elements making up said user ID which are other than the element used to generate said first data registration screen, thereby producing message digest character strings, sequentially sorts the message digest character strings, extracts the position of said constant therein, and extracts identifiers required to form an image at the position, thereby generating said second data registration screen.

11. A method of managing user data on a user data management apparatus having a display unit, for registering data dependent on a user ID peculiar to a user, comprising the steps of:

when data of said user is to be initially registered, generating a first data registration screen, which differs from user ID to user ID; and

when the data of said user is to be registered, displaying, on said display unit, a second data registration screen based on said first data registration screen generated by said first-mentioned step.

12. The method according to claim 11, wherein said first-mentioned step comprises the steps of hashing a character string obtained from any one of a plurality of elements making up said user ID with respect to a constant assigned to a predetermined picture, thereby producing message digest character strings, producing relocating identifiers peculiar to the user by sequentially sorting the message digest character strings, masking a predetermined range of the relocating identifiers from the beginning thereof, and generating said first data registration screen from the relocating identifiers outside of said predetermined range;

and

said second-mentioned step comprises the steps of dehashing said first data registration screen generated by said first means to produce the constant assigned to said predetermined picture, hashing a character string obtained from any element amongst those elements making up said user ID which are other than the element used to generate said first data registration screen, thereby producing message digest character strings, sequentially sorting the message digest character strings, extracting the position of said constant therein, and extracting identifiers required to form an image at the position, thereby generating said second data registration screen.
