Abstract

An information processing apparatus that can easily and safely transmit data. A registering unit registers first authentication information in association with user information indicating a first user. The first authentication information is necessary for the first user to log on to the information processing apparatus. A generating unit generates an address data that is used to transmit data from an external apparatus to the information processing apparatus and includes the user information and second authentication information. A transmitting unit transmits the address data to the external apparatus. An authenticating unit authenticates by utilizing the second authentication information included in the address data when the data is transmitted based on the address data from the external apparatus. A storing unit stores the received data in association with the first user when the authentication by the authenticating unit succeeds.

Claims

1. An information processing apparatus capable of storing data in association with a user, comprising:

a registering unit adapted to register first authentication information in association with user information indicating a first user, the first authentication information being necessary for the first user to log on to the information processing apparatus;

a generating unit adapted to generate an address data, the address data being used to transmit data from an external apparatus to the information processing apparatus, and including the user information and second authentication information;

a transmitting unit adapted to transmit the address data to the external apparatus;

an authenticating unit adapted to authenticate by utilizing the second authentication information included in the address data when the data is transmitted based on the address data from the external apparatus; and

a storing unit adapted to store the received data in association with the first user when the authentication by said authenticating unit succeeds.

2. The information processing apparatus according to claim 1,

wherein said generating unit generates the second authentication information so that the first authentication information and the second authentication information do not become the same as each other.

3. The information processing apparatus according to claim 1, further comprising:

a keeping unit adapted to keep the second authentication information included in the address data,

wherein said authenticating unit authenticates by comparing the second authentication information kept in said keeping unit with the second authentication information included in the address data of the data transmitted from the external apparatus.

4. The information processing apparatus according to claim 1,

wherein said generating unit generates the second authentication information with random numbers.

5. The information processing apparatus according to claim 1,

wherein the data transmitted from the external apparatus is transmitted by using a general-purpose file transfer protocol.

6. The information processing apparatus according to claim 5,

wherein the general-purpose file transfer protocol provides an authenticating function and a data-receiving function.

7. The information processing apparatus according to claim 1, further comprising:

an address storing unit adapted to store an address of a device transmitting the address data through a communication network,

wherein a connection request is not accepted from the device without the address stored in said address storing unit.

8. The information processing apparatus according to claim 7,

wherein said authenticating unit keeps the second authentication information included in the address data, and the address of the external apparatus to which the address data is delivered in a manner that the second authentication information is associated with the address of the external apparatus, and when a combination of the second authentication information of the received data and the address of the external apparatus transmitting the data corresponds to a combination of the kept second authentication information and the address of the external apparatus, it is determined that the authentication succeeds.

9. The information processing apparatus according to claim 1,

wherein said generating unit periodically and automatically generates the address data, and said transmitting unit transmits the automatically-generated address data.

10. The information processing apparatus according to claim 1,

wherein said registering unit registers user information on each of a plurality of the users,

the information processing apparatus further comprises:

a selecting unit adapted to select the user to be registered in the address data from a plurality of pieces of the user information registered in said registering unit, and

said generating unit generates the address data in which the selected user is registered.

11. A control method of an information processing apparatus capable of storing data in association with a user, comprising:

a registration step of registering first authentication information in association with user information indicating a first user, the first authentication information being necessary for the first user to log on to the information processing apparatus;

a generation step of generating an address data, the address data being used to transmit data from an external apparatus to the information processing apparatus, and including the user information and second authentication information;

a transmitting step of transmitting the address data to the external apparatus;

an authentication step of authenticating by utilizing the second authentication information included in the address data when the data is transmitted based on the address data from the external apparatus; and

a storing step of storing the received data in association with the first user when the authentication in said authentication step succeeds.
